$globals[$this->selected_module]->process_button();

[Guest]

in includes/classes/payment.php I've been looking at this section of code:

	function process_button() {
  if (is_array($this->modules)) {
	if (is_object($GLOBALS[$this->selected_module]) && ($GLOBALS[$this->selected_module]->enabled) ) {
	  return $GLOBALS[$this->selected_module]->process_button();
	}
  }
}

Where is it set what $GLOBALS[$this->selected_module]->process_button(); actually is? I really need to be able to change this.

 

Thanks.

Change it to what? This call returns the selected payment's module form contents. And each payment module should include that member function.

okay.. lets say I wanted to change what happens when you click on the process button for a paypal payment.

Would I change the code in includes/modules/payment/paypal.php?

I presume it would be the

	function process_button() {
  global $order, $currencies, $currency;

  if (MODULE_PAYMENT_PAYPAL_CURRENCY == 'Selected Currency') {
	$my_currency = $currency;
  } else {
	$my_currency = substr(MODULE_PAYMENT_PAYPAL_CURRENCY, 5);
  }
  if (!in_array($my_currency, array('CAD', 'EUR', 'GBP', 'JPY', 'USD'))) {
	$my_currency = 'GBP';
  }
  $process_button_string = tep_draw_hidden_field('cmd', '_xclick') .
						   tep_draw_hidden_field('business', MODULE_PAYMENT_PAYPAL_ID) .
						   tep_draw_hidden_field('item_name', STORE_NAME) .
						   tep_draw_hidden_field('amount', number_format(($order->info['total'] - $order->info['shipping_cost']) * $currencies->get_value($my_currency), $currencies->get_decimal_places($my_currency))) .
						   tep_draw_hidden_field('shipping', number_format($order->info['shipping_cost'] * $currencies->get_value($my_currency), $currencies->get_decimal_places($my_currency))) .
						   tep_draw_hidden_field('currency_code', $my_currency) .
						   tep_draw_hidden_field('return', tep_href_link(FILENAME_CHECKOUT_PROCESS, '', 'SSL')) .
						   tep_draw_hidden_field('cancel_return', tep_href_link(FILENAME_CHECKOUT_PAYMENT, '', 'SSL'));

  return $process_button_string;
}

I need to alter to change how the button works?

The process_button function all it does it returns back the form content specific to paypal. The button for the form is processed by the checkout_confirmation.php. (Basically it just submits the form) by default

 

So if you need to change the behavior only when it's for paypal you could use the "title" or "code" variables because these are common for each payment module and you can access them from the checkout_confirmation.php

 

 if (isset($$payment->code) && $$payment->code =='paypal')) {
//do something paypal specfic
}

Thanks,

I've used this code:

if($order->info['payment_method'] == 'PayPal'){
//do something paypal specfic
}

 

would your code be more suitable?

it's the same thing. just make sure the title of your paypal module is "PayPal" and not "paypal" case sensitivity matters.
