Laravel-Payzen

The library provides an easy and fast Payzen form creation. This helps to instanciate all required parameters and create the form to access to payment interface. To know required parameters, go to https://payzen.io/en-EN/form-payment/quick-start-guide/sending-a-payment-form-via-post.html

Installation

First you need to add the component to your composer.json

composer require noweh/laravel-payzen

Update your packages with composer update or install with composer install.

Laravel uses Package Auto-Discovery, so doesn't require you to manually add the ServiceProvider.

Laravel without auto-discovery

Noweh\Payzen\PayzenServiceProvider::class,

To use the facade, add this in app.php:

'Payzen' => Noweh\Payzen\PayzenFacade::class,

Service Provider

After updating composer, add the ServiceProvider to the providers array in config/app.php

Configuration file

Next, you must migrate config :

php artisan vendor:publish --provider="Noweh\Payzen\PayzenServiceProvider"

Create a payment form

Now we are finally ready to use the package! Here is a little example:

     $blocks_html = \Payzen::set_amount(300)
        ->set_trans_id(123456)
        ->set_order_info(\Payzen::ascii_transcode('an information', 'an', 255, true))
        ->set_order_info2(\Payzen::ascii_transcode('another information', 'an', 255, true))
        ->set_url_return(request()->fullUrl())
        ->set_return_mode('POST')
        ->set_signature()
        ->get_form('<div><input id="spSubmit" type="submit" value="Pay" class="Button Button--black"></div>')
    ;

Check Payzen response signature

     $payzen = \Payzen::set_params(\Arr::where(request()->all(), function($value, $key) {
                 	return strrpos($key, 'vads_', -5) !== false;
             	}))
     			->set_signature()
     		;
             return (request()->input('signature') && ($payzen::get_signature() === request()->input('signature')));
    ;
