Classipress 3.3 custom payment gateway plugin error

Hi all

I have written a custom gateway plugin for WP 3.6.
I followed instructions on the article
http://docs.appthemes.com/developers/creating-a-payment-gateway/

So my-plugin-gateway.php is:

//-------------
class My_Gateway extends APP_Gateway{

}
appthemes_register_gateway( 'My_Gateway' );
//--------------

and my-plugin.php is :

//--------------
add_action( 'init', 'my_plugin_setup' );
function my_plugin_setup(){
include 'my-plugin-gateway.php';
}
//--------------

Pretty simple, yeah?

But when I tried to install it or use it I got the following error:
Fatal error: Class 'APP_Gateway' not found in my-plugin-gateway.php

I solved it by adding the following to the top of the
my-plugin-gateway.php :

require_once ABSPATH . 'wp-content/themes/classipress/includes/payments/gateways/gateway-class.php';
require_once ABSPATH . 'wp-content/themes/classipress/includes/payments/gateways/boomerang-class.php';
require_once ABSPATH . 'wp-content/themes/classipress/includes/payments/gateways/gateway-registry.php';
require_once ABSPATH . 'wp-content/themes/classipress/includes/payments/gateways/gateway-functions.php';

But after that I got the following error:

Fatal error: Cannot redeclare class APP_Gateway in wp-content\themes\classipress\includes\payments\gateways\gateway-class.php on line 6

To fix it I had to replace in the file
wp-content\themes\classipress\includes\payments\load.php the
following code on line 43

/// Gateways
require dirname( __FILE__ ) . '/gateways/gateway-class.php';
require dirname( __FILE__ ) . '/gateways/boomerang-class.php';
require dirname( __FILE__ ) . '/gateways/gateway-registry.php';
require dirname( __FILE__ ) . '/gateways/gateway-functions.php';

to this one:

/// Gateways
require_once dirname( __FILE__ ) . '/gateways/gateway-class.php';
require_once dirname( __FILE__ ) . '/gateways/boomerang-class.php';
require_once dirname( __FILE__ ) . '/gateways/gateway-registry.php';
require_once dirname( __FILE__ ) . '/gateways/gateway-functions.php';

I wonder if I did the right thing. Maybe there is some other way to
avoid those errors without having to modify classipress core?

Thank you!

Best regards

Did you put the comments that declare the plugin in my-plugin-gateway.php
or my-plugin.php? According to the docs I believe you need it in
my-plugin.php. Whatever file the plugin declaration is in is loaded by
WordPress, so if that's your gateway file, that class will be included,
throwing the error.

Hi Taras,

I don't have the Classipress theme, so I can't actually look in the source
code, but I can take a guess here:

#1 Add a priority to your add_action call, like so:
add_action( 'init', 'my_plugin_setup', 1000 );

#2 If that doesn't work for you, try changing 'init' to one of the other
action hooks described here -
http://codex.wordpress.org/Plugin_API/Action_Reference

That's as far as I my guesses go. I simply assume that the gateway class is
initialized(included) later on compared to when your my_plugin_setup()
function is being called.

Hi Nikola

The first guess is the right one, thank you! :)
I tried it before. But it have worked only after I removed
plugin completely, reloaded WP and then replaced the code with

add_action( 'init', 'online_naira_setup', 1000 );

Thanks a lot!
