Package configuration file

Before using this package, you need to receive two dedicated keys from each of the Captcha servers. In order to receive the keys, you must register in each of the Captcha servers and receive the keys. for receive Arcaptcha service keys to Arcaptcha registration address , for receive Bibot keys to Bibot registration address, for receive recaptcha keys to Recaptcha registration address and for receive hcaptcha keys to hCaptcha registration address . Get the keys to act. Then go to a app/ThirdParty/CIMultiCaptcha/Config and replace the relevant site_key and secret_key keys in the MultiCaptchaCIConfig.php file. If you need to change the color, theme, size and... proceed through this file. In the case of the captcha language, the package defaults to any language set in the CI framework and displays the captcha in the same language. If you need to customize the captcha language, set the lang values through this file. Important point in this regard, the two Iranian servers (Arcaptcha and Bibot) support only two languages Persian (fa) and English (en), this restriction is related to captcha servers and not the package.

How to use (CIMC)

In general, how to use this package will be in two ways. The first method is to select the service by the programmer, for example, the programmer intends to use only the recaptcha service, so he must follow the blue path according to the diagram below. The next item is the programmer has no role in specifying the service. The system randomly selects one of the services, to do this you have to follow the black path.
