A CMS that will enable you to create truly amazing websites through easy-to-use features and a large contributing community.
Expression Engine is an extensive content and membership management system. Membrr is a plugin for ExpressionEngine that brings paid subscription membership website functionality to a powerful CMS.
The first step is to integrate your forms. Login to your Expression Engine (EE) control panel and navigate to Design> Templates> Edit and edit the form your want to integrate. Do this multiple times in case you want to integrate more of your forms.
Find the and form tag </form> and add this code above it:
Save your changes.
Your forms are integrated, so each form is sending an extra value with a tracking cookie value. You have to process it.
If you are not a programmer, ask one to help you as this is a programming task.
Connect to your server through FTP and find directory opengateway/system/opengateway/libraries/payment/
There are all payment gateways which you can integrate. Integrate those which you are going to use. The main idea is to load the custom value which a form sent you and send the value to the payment gateway.
This is an example for PayPal:
Edit file paypal.php and find function Charge(). Find a line which calls function $this->Process() and add this code above it:
$post['custom'] = $_POST['pap_custom'];
Save your work.
Now the last step is to activate a plugin for the integrated payment gateway in your Post Affiliate Pro and make sure a payment notification is sent to the plugin. To understand it more, check the original integration method for the payment gateway.
