DB Models and Eloquent

⬆️ Go to top ➡️ Next (Models Relations)

Reuse or clone query()

Typically, we need to query multiple time from a filtered query. So, most of the time we use query() method,

let's write a query for getting today created active and inactive products

$query = Product::query();


$today = request()->q_date ?? today();
if($today){
    $query->where('created_at', $today);
}

// lets get active and inactive products
$active_products = $query->where('status', 1)->get(); // this line modified the $query object variable
$inactive_products = $query->where('status', 0)->get(); // so here we will not find any incative products

But, after getting $active products the$querywill be modified. So, $inactive_products will not find any inactive products from $query and that will return blank collection every time. Cause, that will try to find inactive products from $active_products ($query will return active products only).

For solve this issue, we can query multiple time by reusing this $query object. So, We need to clone this $query before doing any $query modification action.

$active_products = (clone $query)->where('status', 1)->get(); // it will not modify the $query
$inactive_products = (clone $query)->where('status', 0)->get(); // so we will get inactive products from $query

Eloquent where date methods

In Eloquent, check the date with functions whereDay(), whereMonth(), whereYear(), whereDate() and whereTime().

$products = Product::whereDate('created_at', '2018-01-31')->get();
$products = Product::whereMonth('created_at', '12')->get();
$products = Product::whereDay('created_at', '31')->get();
$products = Product::whereYear('created_at', date('Y'))->get();
$products = Product::whereTime('created_at', '=', '14:13:58')->get();

Increments and decrements

If you want to increment some DB column in some table, just use increment() function. Oh, and you can increment not only by 1, but also by some number, like 50.

Post::find($post_id)->increment('view_count');
User::find($user_id)->increment('points', 50);

No timestamp columns

If your DB table doesn't contain timestamp fields created_at and updated_at, you can specify that Eloquent model wouldn't use them, with $timestamps = false property.

class Company extends Model
{
    public $timestamps = false;
}

Soft-deletes: multiple restore

When using soft-deletes, you can restore multiple rows in one sentence.

Post::onlyTrashed()->where('author_id', 1)->restore();

Model all: columns

When calling Eloquent's Model::all(), you can specify which columns to return.

$users = User::all(['id', 'name', 'email']);

To Fail or not to Fail

In addition to findOrFail(), there's also Eloquent method firstOrFail() which will return 404 page if no records for query are found.

$user = User::where('email', '[email protected]')->firstOrFail();

Column name change

In Eloquent Query Builder, you can specify "as" to return any column with a different name, just like in plain SQL query.

$users = DB::table('users')->select('name', 'email as user_email')->get();

Map query results

After Eloquent query you can modify rows by using map() function in Collections.

$users = User::where('role_id', 1)->get()->map(function (User $user) {
    $user->some_column = some_function($user);
    return $user;
});

Change Default Timestamp Fields

What if you’re working with non-Laravel database and your timestamp columns are named differently? Maybe, you have create_time and update_time. Luckily, you can specify them in the model, too:

class Role extends Model
{
    const CREATED_AT = 'create_time';
    const UPDATED_AT = 'update_time';
}

Quick Order by created_at

Instead of:

User::orderBy('created_at', 'desc')->get();

You can do it quicker:

User::latest()->get();

By default, latest() will order by created_at.

There is an opposite method oldest() which would order by created_at ascending:

User::oldest()->get();

Also, you can specify another column to order by. For example, if you want to use updated_at, you can do this:

$lastUpdatedUser = User::latest('updated_at')->first();

Automatic Column Value When Creating Records

If you want to generate some DB column value when creating record, add it to model's boot() method. For example, if you have a field "position" and want to assign the next available position to the new record (like Country::max('position') + 1), do this:

class Country extends Model {
    protected static function boot()
    {
        parent::boot();

        Country::creating(function($model) {
            $model->position = Country::max('position') + 1;
        });
    }
}

DB Raw Query Calculations Run Faster

Use SQL raw queries like whereRaw() method, to make some DB-specific calculations directly in query, and not in Laravel, usually the result will be faster. Like, if you want to get users that were active 30+ days after their registration, here's the code:

User::where('active', 1)
    ->whereRaw('TIMESTAMPDIFF(DAY, created_at, updated_at) > ?', 30)
    ->get();

More than One Scope

You can combine and chain Query Scopes in Eloquent, using more than one scope in a query.

Model:

public function scopeActive($query) {
    return $query->where('active', 1);
}

public function scopeRegisteredWithinDays($query, $days) {
    return $query->where('created_at', '>=', now()->subDays($days));
}

Some Controller:

$users = User::registeredWithinDays(30)->active()->get();

No Need to Convert Carbon

If you're performing whereDate() and check today's records, you can use Carbon's now() and it will automatically be transformed to date. No need to do ->toDateString().

// Instead of
$todayUsers = User::whereDate('created_at', now()->toDateString())->get();
// No need to convert, just use now()
$todayUsers = User::whereDate('created_at', now())->get();

Grouping by First Letter

You can group Eloquent results by any custom condition, here's how to group by first letter of user's name:

$users = User::all()->groupBy(function($item) {
    return $item->name[0];
});

Never Update the Column

If you have DB column which you want to be set only once and never updated again, you can set that restriction on Eloquent Model, with a mutator:

class User extends Model
{
    public function setEmailAttribute($value)
    {
        if ($this->email) {
            return;
        }

        $this->attributes['email'] = $value;
    }
}

Find Many

Eloquent method find() may accept multiple parameters, and then it returns a Collection of all records found, not just one Model:

// Will return Eloquent Model
$user = User::find(1);
// Will return Eloquent Collection
$users = User::find([1,2,3]);

Find by Key

You can also find multiple records with whereKey() method which takes care of which field is exactly your primary key (id is the default but you may override it in Eloquent model):

$users = User::whereKey([1,2,3])->get();

Use UUID instead of auto-increment

You don't want to use auto incrementing ID in your model?

Migration:

Schema::create('users', function (Blueprint $table) {
    // $table->increments('id');
    $table->uuid('id')->unique();
});

Model:

class User extends Model
{
    public $incrementing = false;
    protected $keyType = 'string';

    protected static function boot()
    {
        parent::boot();

        User::creating(function ($model) {
            $model->setId();
        });
    }

    public function setId()
    {
        $this->attributes['id'] = Str::uuid();
    }
}

Sub-selects in Laravel Way

From Laravel 6, you can use addSelect() in Eloquent statement, and do some calculation to that added column.

return Destination::addSelect(['last_flight' => Flight::select('name')
    ->whereColumn('destination_id', 'destinations.id')
    ->orderBy('arrived_at', 'desc')
    ->limit(1)
])->get();

Hide Some Columns

When doing Eloquent query, if you want to hide specific field from being returned, one of the quickest ways is to add ->makeHidden() on Collection result.

$users = User::all()->makeHidden(['email_verified_at', 'deleted_at']);

Exact DB Error

If you want to catch Eloquent Query exceptions, use specific QueryException instead default Exception class, and you will be able to get the exact SQL code of the error.

try {
    // Some Eloquent/SQL statement
} catch (\Illuminate\Database\QueryException $e) {
    if ($e->getCode() === '23000') { // integrity constraint violation
        return back()->withError('Invalid data');
    }
}

Soft-Deletes with Query Builder

Don't forget that soft-deletes will exclude entries when you use Eloquent, but won't work if you use Query Builder.

// Will exclude soft-deleted entries
$users = User::all();

// Will NOT exclude soft-deleted entries
$users = User::withTrashed()->get();

// Will NOT exclude soft-deleted entries
$users = DB::table('users')->get();

Good Old SQL Query

If you need to execute a simple SQL query, without getting any results - like changing something in DB schema, you can just do DB::statement().

DB::statement('DROP TABLE users');
DB::statement('ALTER TABLE projects AUTO_INCREMENT=123');

Use DB Transactions

If you have two DB operations performed, and second may get an error, then you should rollback the first one, right?

For that, I suggest to use DB Transactions, it's really easy in Laravel:

DB::transaction(function () {
    DB::table('users')->update(['votes' => 1]);

    DB::table('posts')->delete();
});

Update or Create

If you need to check if the record exists, and then update it, or create a new record otherwise, you can do it in one sentence - use Eloquent method updateOrCreate():

// Instead of this
$flight = Flight::where('departure', 'Oakland')
    ->where('destination', 'San Diego')
    ->first();
if ($flight) {
    $flight->update(['price' => 99, 'discounted' => 1]);
} else {
	$flight = Flight::create([
	    'departure' => 'Oakland',
	    'destination' => 'San Diego',
	    'price' => 99,
	    'discounted' => 1
	]);
}
// Do it in ONE sentence
$flight = Flight::updateOrCreate(
    ['departure' => 'Oakland', 'destination' => 'San Diego'],
    ['price' => 99, 'discounted' => 1]
);

Forget Cache on Save

Tip given by @pratiksh404

If you have cache key like posts that gives collection, and you want to forget that cache key on new store or update, you can call static saving function on your model:

class Post extends Model
{
    // Forget cache key on storing or updating
    public static function boot()
    {
        parent::boot();
        static::saving(function () {
           Cache::forget('posts');
        });
    }
}

Change Format Of Created_at and Updated_at

Tip given by @syofyanzuhad

To change the format of created_at you can add a method in your model like this:

public function getCreatedAtFormattedAttribute()
{
   return $this->created_at->format('H:i d, M Y');
}

So you can use it $entry->created_at_formatted when it's needed. It will return the created_at attribute like this: 04:19 23, Aug 2020.

And also for changing format of updated_at attribute, you can add this method :

public function getUpdatedAtFormattedAttribute()
{
   return $this->updated_at->format('H:i d, M Y');
}

So you can use it $entry->updated_at_formatted when it's needed. It will return the updated_at attribute like this: 04:19 23, Aug 2020.

Storing Array Type into JSON

Tip given by @pratiksh404

If you have input field which takes an array and you have to store it as a JSON, you can use $casts property in your model. Here images is a JSON attribute.

protected $casts = [
    'images' => 'array',
];

So you can store it as a JSON, but when retrieved from DB, it can be used as an array.

Make a Copy of the Model

If you have two very similar Models (like shipping address and billing address) and you need to make a copy of one to another, you can use replicate() method and change some properties after that.

Example from the official docs:

$shipping = Address::create([
    'type' => 'shipping',
    'line_1' => '123 Example Street',
    'city' => 'Victorville',
    'state' => 'CA',
    'postcode' => '90001',
]);

$billing = $shipping->replicate()->fill([
    'type' => 'billing'
]);

$billing->save();

Reduce Memory

Sometimes we need to load a huge amount of data into memory. For example:

$orders = Order::all();

But this can be slow if we have really huge data, because Laravel prepares objects of the Model class. In such cases, Laravel has a handy function toBase()

$orders = Order::toBase()->get();
//$orders will contain `Illuminate\Support\Collection` with objects `StdClass`.

By calling this method, it will fetch the data from the database, but it will not prepare the Model class. Keep in mind it is often a good idea to pass an array of fields to the get method, preventing all fields to be fetched from the database.

Force query without $fillable/$guarded

If you create a Laravel boilerplate as a "starter" for other devs, and you're not in control of what THEY would later fill in Model's $fillable/$guarded, you may use forceFill()

$team->update(['name' => $request->name])

What if "name" is not in Team model's $fillable? Or what if there's no $fillable/$guarded at all?

$team->forceFill(['name' => $request->name])

This will "ignore" the $fillable for that one query and will execute no matter what.

3-level structure of parent-children

If you have a 3-level structure of parent-children, like categories in an e-shop, and you want to show the number of products on the third level, you can use with('yyy.yyy') and then add withCount() as a condition

class HomeController extend Controller
{
    public function index()
    {
        $categories = Category::query()
            ->whereNull('category_id')
            ->with(['subcategories.subcategories' => function($query) {
                $query->withCount('products');
            }])->get();
    }
}
class Category extends Model
{
    public function subcategories()
    {
        return $this->hasMany(Category::class);
    }
    
    public function products()
    {
    return $this->hasMany(Product::class);
    }
}
    
    @foreach($categories as $category)
        
  • 
            {{ $category->name }}
            @if ($category->subcategories)
                
      
                @foreach($category->subcategories as $subcategory)
                    
    • 
                        {{ $subcategory->name }}
                        @if ($subcategory->subcategories)
                            
        
                                @foreach ($subcategory->subcategories as $subcategory)
                                    
      • {{ $subcategory->name }} ({{ $subcategory->product_count }})
        • 
                                @endforeach
                            
      
                        @endif
                    
      • 
                @endforeach
                
    
            @endif
        
    • 
    @endforeach

Use find to search multiple records

You can use Eloquent find() not only to search for one record but also to return a collection of multiple records by their IDs. Instead of

return Product::whereIn('id', $this->productIDs)->get();

You can do this

return Product::find($this->productIDs)

Perform any action on failure

When looking for a record, you may want to perform some actions if it's not found. In addition to ->firstOrFail() which just throws 404, you can perform any action on failure, just do ->firstOr(function() { ... })

$model = Flight::where('legs', '>', 3)->firstOr(function () {
    // ...
})

Check if record exists or show 404

Don't use find() and then check if the record exists. Use findOrFail() or optional().

$product = Product::find($id);
if ($product) {
    $product->update($productDataArray);
}

Shorter way

$product = Product::findOrFail($id); // shows 404 if not found
$product->update($productDataArray);

Even shorter

optional(Product::find($id))->update($productDataArray);

Models Relations

⬆️ Go to top ⬅️ Previous (DB Models and Eloquent) ➡️ Next (Migrations)

OrderBy on Eloquent relationships

You can specify orderBy() directly on your Eloquent relationships.

public function products()
{
    return $this->hasMany(Product::class);
}

public function productsByName()
{
    return $this->hasMany(Product::class)->orderBy('name');
}

Conditional relationships

If you notice that you use same relationship often with additional "where" condition, you can create a separate relationship method.

Model:

public function comments()
{
    return $this->hasMany(Comment::class);
}

public function approved_comments()
{
    return $this->hasMany(Comment::class)->where('approved', 1);
}

Raw DB Queries: havingRaw()

You can use RAW DB queries in various places, including havingRaw() function after groupBy().

Product::groupBy('category_id')->havingRaw('COUNT(*) > 1')->get();

Eloquent has() deeper

You can use Eloquent has() function to query relationships even two layers deep!

// Author -> hasMany(Book::class);
// Book -> hasMany(Rating::class);
$authors = Author::has('books.ratings')->get();

Has Many. How many exactly?

In Eloquent hasMany() relationships, you can filter out records that have X amount of children records.

// Author -> hasMany(Book::class)
$authors = Author::has('books', '>', 5)->get();

Default model

You can assign a default model in belongsTo relationship, to avoid fatal errors when calling it like {{ $post->user->name }} if $post->user doesn't exist.

public function user()
{
    return $this->belongsTo('App\User')->withDefault();
}

Use hasMany to create Many

If you have hasMany() relationship, you can use saveMany() to save multiple "child" entries from your "parent" object, all in one sentence.

$post = Post::find(1);
$post->comments()->saveMany([
    new Comment(['message' => 'First comment']),
    new Comment(['message' => 'Second comment']),
]);

Multi level Eager Loading

In Laravel you can Eager Load multiple levels in one statement, in this example we not only load the author relation but also the country relation on the author model.

$users = App\Book::with('author.country')->get();

Eager Loading with Exact Columns

You can do Laravel Eager Loading and specify the exact columns you want to get from the relationship.

$users = App\Book::with('author:id,name')->get();

You can do that even in deeper, second level relationships:

$users = App\Book::with('author.country:id,name')->get();

Touch parent updated_at easily

If you are updating a record and want to update the updated_at column of parent relationship (like, you add new post comment and want posts.updated_at to renew), just use $touches = ['post']; property on child model.

class Comment extends Model
{
    protected $touches = ['post'];
}

Always Check if Relationship Exists

Never ever do $model->relationship->field without checking if relationship object still exists.

It may be deleted for whatever reason, outside your code, by someone else's queued job etc. Do if-else, or {{ $model->relationship->field ?? '' }} in Blade, or {{ optional($model->relationship)->field }}. With php8 you can even use the nullsafe operator {{ $model->relationship?->field) }}

Use withCount() to Calculate Child Relationships Records

If you have hasMany() relationship, and you want to calculate “children” entries, don’t write a special query. For example, if you have posts and comments on your User model, write this withCount():

public function index()
{
    $users = User::withCount(['posts', 'comments'])->get();
    return view('users', compact('users'));
}

And then, in your Blade file, you will access those number with {relationship}_count properties:

{{ $user->posts_count }} {{ $user->comments_count }} @endforeach "> 
@foreach ($users as $user)
<tr>
    <td>{{ $user->name }}td>
    <td class="text-center">{{ $user->posts_count }}td>
    <td class="text-center">{{ $user->comments_count }}td>
tr>
@endforeach

You may also order by that field:

User::withCount('comments')->orderBy('comments_count', 'desc')->get();

Extra Filter Query on Relationships

If you want to load relationship data, you can specify some limitations or ordering in a closure function. For example, if you want to get Countries with only three of their biggest cities, here's the code.

$countries = Country::with(['cities' => function($query) {
    $query->orderBy('population', 'desc');
    $query->take(3);
}])->get();

Load Relationships Always, but Dynamically

You can not only specify what relationships to ALWAYS load with the model, but you can do it dynamically, in the constructor method:

class ProductTag extends Model
{
    protected $with = ['product'];

    public function __construct() {
        parent::__construct();
        $this->with = ['product'];
        
        if (auth()->check()) {
            $this->with[] = 'user';
        }
    }
}

Instead of belongsTo, use hasMany

For belongsTo relationship, instead of passing parent's ID when creating child record, use hasMany relationship to make a shorter sentence.

// if Post -> belongsTo(User), and User -> hasMany(Post)...
// Then instead of passing user_id...
Post::create([
    'user_id' => auth()->id(),
    'title' => request()->input('title'),
    'post_text' => request()->input('post_text'),
]);

// Do this
auth()->user()->posts()->create([
    'title' => request()->input('title'),
    'post_text' => request()->input('post_text'),
]);

Rename Pivot Table

If you want to rename "pivot" word and call your relationship something else, you just use ->as('name') in your relationship.

Model:

public function podcasts() {
    return $this->belongsToMany('App\Podcast')
        ->as('subscription')
        ->withTimestamps();
}

Controller:

$podcasts = $user->podcasts();
foreach ($podcasts as $podcast) {
    // instead of $podcast->pivot->created_at ...
    echo $podcast->subscription->created_at;
}

Update Parent in One Line

If you have a belongsTo() relationship, you can update the Eloquent relationship data in the same sentence:

// if Project -> belongsTo(User::class)
$project->user->update(['email' => '[email protected]']);

Laravel 7+ Foreign Keys

From Laravel 7, in migrations you don't need to write two lines for relationship field - one for the field and one for foreign key. Use method foreignId().

// Before Laravel 7
Schema::table('posts', function (Blueprint $table)) {
    $table->unsignedBigInteger('user_id');
    $table->foreign('user_id')->references('id')->on('users');
}

// From Laravel 7
Schema::table('posts', function (Blueprint $table)) {
    $table->foreignId('user_id')->constrained();
}

// Or, if your field is different from the table reference
Schema::table('posts', function (Blueprint $table)) {
    $table->foreignId('created_by_id')->constrained('users', 'column');
}

Combine Two "whereHas"

In Eloquent, you can combine whereHas() and orDoesntHave() in one sentence.

User::whereHas('roles', function($query) {
    $query->where('id', 1);
})
->orDoesntHave('roles')
->get();

Check if Relationship Method Exists

If your Eloquent relationship names are dynamic and you need to check if relationship with such name exists on the object, use PHP function method_exists($object, $methodName)

$user = User::first();
if (method_exists($user, 'roles')) {
	// Do something with $user->roles()->...
}

Pivot Table with Extra Relations

In many-to-many relationship, your pivot table may contain extra fields, and even extra relationships to other Model.

Then generate a separate Pivot Model:

php artisan make:model RoleUser --pivot

Next, specify it in belongsToMany() with ->using() method. Then you could do magic, like in the example.

// in app/Models/User.php
public function roles()
{
	return $this->belongsToMany(Role::class)
	    ->using(RoleUser::class)
	    ->withPivot(['team_id']);
}

// app/Models/RoleUser.php: notice extends Pivot, not Model
use Illuminate\Database\Eloquent\Relations\Pivot;

class RoleUser extends Pivot
{
	public function team()
	{
	    return $this->belongsTo(Team::class);
	}
}

// Then, in Controller, you can do:
$firstTeam = auth()->user()->roles()->first()->pivot->team->name;

Load Count on-the-fly

In addition to Eloquent's withCount() method to count related records, you can also load the count on-the-fly, with loadCount():

// if your Book hasMany Reviews...
$book = App\Book::first();

$book->loadCount('reviews');
// Then you get access to $book->reviews_count;

// Or even with extra condition
$book->loadCount(['reviews' => function ($query) {
    $query->where('rating', 5);
}]);

Randomize Relationship Order

You can use inRandomOrder() to randomize Eloquent query result, but also you can use it to randomize the relationship entries you're loading with query.

// If you have a quiz and want to randomize questions...

// 1. If you want to get questions in random order:
$questions = Question::inRandomOrder()->get();

// 2. If you want to also get question options in random order:
$questions = Question::with(['answers' => function($q) {
    $q->inRandomOrder();
}])->inRandomOrder()->get();

Filter hasMany relationships

Just a code example from my project, showing the possibility of filtering hasMany relationships.
TagTypes -> hasMany Tags -> hasMany Examples
And you wanna query all the types, with their tags, but only those that have examples, ordering by most examples.

$tag_types = TagType::with(['tags' => function ($query) {
    $query->has('examples')
        ->withCount('examples')
        ->orderBy('examples_count', 'desc');
    }])->get();

Filter by many-to-many relationship pivot column

If you have a many-to-many relationship, and you add an extra column to the pivot table, here's how you can order by it when querying the list.

class Tournament extends Model
{
    public function countries()
    {
        return $this->belongsToMany(Country::class)->withPivot(['position']);
    }
}
class TournamentsController extends Controller

public function whatever_method() {
    $tournaments = Tournament::with(['countries' => function($query) {
            $query->orderBy('position');
        }])->latest()->get();
}

Migrations

⬆️ Go to top ⬅️ Previous (Models Relations) ➡️ Next (Views)

Unsigned Integer

For foreign key migrations instead of integer() use unsignedInteger() type or integer()->unsigned(), otherwise you may get SQL errors.

Schema::create('employees', function (Blueprint $table) {
    $table->unsignedInteger('company_id');
    $table->foreign('company_id')->references('id')->on('companies');
    // ...
});

You can also use unsignedBigInteger() if that other column is bigInteger() type.

Schema::create('employees', function (Blueprint $table) {
    $table->unsignedBigInteger('company_id');
});

Order of Migrations

If you want to change the order of DB migrations, just rename the file's timestamp, like from 2018_08_04_070443_create_posts_table.php to2018_07_04_070443_create_posts_table.php (changed from 2018_08_04 to 2018_07_04).

They run in alphabetical order.

Migration fields with timezones

Did you know that in migrations there's not only timestamps() but also timestampsTz(), for the timezone?

Schema::create('employees', function (Blueprint $table) {
    $table->increments('id');
    $table->string('name');
    $table->string('email');
    $table->timestampsTz();
});

Also, there are columns dateTimeTz(), timeTz(), timestampTz(), softDeletesTz().

Database migrations column types

There are interesting column types for migrations, here are a few examples.

$table->geometry('positions');
$table->ipAddress('visitor');
$table->macAddress('device');
$table->point('position');
$table->uuid('id');

See all column types on the official documentation.

Default Timestamp

While creating migrations, you can use timestamp() column type with option useCurrent() and useCurrentOnUpdate(), it will set CURRENT_TIMESTAMP as default value.

$table->timestamp('created_at')->useCurrent();
$table->timestamp('updated_at')->useCurrentOnUpdate();

Migration Status

If you want to check what migrations are executed or not yet, no need to look at the database "migrations" table, you can launch php artisan migrate:status command.

Example result:

+------+------------------------------------------------+-------+
| Ran? | Migration                                      | Batch |
+------+------------------------------------------------+-------+
| Yes  | 2014_10_12_000000_create_users_table           | 1     |
| Yes  | 2014_10_12_100000_create_password_resets_table | 1     |
| No   | 2019_08_19_000000_create_failed_jobs_table     |       |
+------+------------------------------------------------+-------+

Create Migration with Spaces

When typing make:migration command, you don't necessarily have to use underscore _ symbol between parts, like create_transactions_table. You can put the name into quotes and then use spaces instead of underscores.

// This works
php artisan make:migration create_transactions_table

// But this works too
php artisan make:migration "create transactions table"

Create Column after Another Column

Notice: Only MySQL

If you're adding a new column to the existing table, it doesn't necessarily have to become the last in the list. You can specify after which column it should be created:

Schema::table('users', function (Blueprint $table) {
    $table->string('phone')->after('email');
});

If you're adding a new column to the existing table, it doesn't necessarily have to become the last in the list. You can specify before which column it should be created:

Schema::table('users', function (Blueprint $table) {
    $table->string('phone')->before('created_at');
});

If you want your column to be the first in your table , then use the first method.

Schema::table('users', function (Blueprint $table) {
    $table->string('uuid')->first();
});

Make migration for existing table

If you make a migration for existing table, and you want Laravel to generate the Schema::table() for you, then add "_in_xxxxx_table" at the end, or specify "--table" parameter. php artisan change_fields_products_table generates empty class

class ChangeFieldsProductsTable extends Migration
{
    public function up()
    {
        //
    }
}

But add in_xxxxx_table php artisan make:migration change_fields_in_products_table and it generates class with Schemma::table() pre-fileed

class ChangeFieldsProductsTable extends Migration
{
    public function up()
    {
        Schema::table('products', function (Blueprint $table) {
            //
        })
    };
}

Also you can specify --table parameter php artisan make:migration whatever_you_want --table=products

class WhateverYouWant extends Migration
{
    public function up()
    {
        Schema::table('products', function (Blueprint $table) {
            //
        })
    };
}

Views

⬆️ Go to top ⬅️ Previous (Migrations) ➡️ Next (Routing)

$loop variable in foreach

Inside of foreach loop, check if current entry is first/last by just using $loop variable.

@foreach ($users as $user)
     @if ($loop->first)
        This is the first iteration.
     @endif

     @if ($loop->last)
        This is the last iteration.
     @endif

     <p>This is user {{ $user->id }}p>
@endforeach

There are also other properties like $loop->iteration or $loop->count. Learn more on the official documentation.

Does view file exist?

You can check if View file exists before actually loading it.

if (view()->exists('custom.page')) {
 // Load the view
}

You can even load an array of views and only the first existing will be actually loaded.

return view()->first(['custom.dashboard', 'dashboard'], $data);

Error code Blade pages

If you want to create a specific error page for some HTTP code, like 500 - just create a blade file with this code as filename, in resources/views/errors/500.blade.php, or 403.blade.php etc, and it will automatically be loaded in case of that error code.

View without controllers

If you want route to just show a certain view, don't create a Controller method, just use Route::view() function.

// Instead of this
Route::get('about', 'TextsController@about');
// And this
class TextsController extends Controller
{
    public function about()
    {
        return view('texts.about');
    }
}
// Do this
Route::view('about', 'texts.about');

Blade @auth

Instead of if-statement to check logged in user, use @auth directive.

Typical way:

@if(auth()->user())
    // The user is authenticated.
@endif

Shorter:

@auth
    // The user is authenticated.
@endauth

The opposite is @guest directive:

@guest
    // The user is not authenticated.
@endguest

Two-level $loop variable in Blade

In Blade's foreach you can use $loop variable even in two-level loop to reach parent variable.

@foreach ($users as $user)
    @foreach ($user->posts as $post)
        @if ($loop->parent->first)
            This is first iteration of the parent loop.
        @endif
    @endforeach
@endforeach

Create Your Own Blade Directive

It’s very easy - just add your own method in app/Providers/AppServiceProvider.php. For example, if you want to have this for replace
tags with new lines:

    I am not talking about Http::pool(). This just does all given calls at once. I am talking about crawler situations where you are crawling 100s of urls and want a concurrency of 10 requests at a time without creating a new Pool every time 10 are done.

    Fix Various Spelling Error, Syntax Highlighting and inconsistent code formatting

    Hi Povilas!

    I found some spelling errors when i visiting the tips ...
    So i decide to clone the repository and ask PhpStorm to find all the spelling errors and fix it for this PR...

    While i reading some tips, i found out that some syntax highlighting is a bit off due to incorrect syntax, so i manually fix it and put under one PR.

    AND when i try to write this description... I realize i also contribute to this repo almost same time last year, so i guess its a one year anniversary ? 🥳

    Please let me know if any changes need to be made 😉

    As always, thanks for maintaining this tips collection
