Porting CCBill Module

**dbailey1980** · 21 Jan 2010, 07:30 PM

Hi

I am trying to port the oscommerce payment module ccbill dynamic pricing and have completed the changes laid out in the wiki.

The problem I have encountered is Fatal error: Call to a member function Execute() on a non-object in C:\wamp\www\zen-cart\zen-cart\includes\modules\payment\ccBillDynamicPricing.php on line 49

I have tried out the fixes for that error I have found in the forum and cant make it work.

I am using v1.3.8a
PHP 5.2.6
MySQL 5.1.36

This is the code where the error is showing

Code:

function check(){
		if (!isset($this->_check)) {
			$check_query = $db->Execute("select configuration_value from " . TABLE_CONFIGURATION . " 
				where configuration_key = 'MODULE_PAYMENT_CCBILL_DYNAMICPRICING_STATUS'");
		$this->_check = $check_query->RecordCount();
		}
		return $this->_check;
	}

This is the code I created from using the wiki

Code:

<?php

class ccBillDynamicPricing {
	var $code, $title, $description, $enable;

	function ccBillDynamicPricing(){
		global $order;

		$this->code = 'ccBillDynamicPricing';

		if ((int)MODULE_PAYMENT_CCBILL_DYNAMICPRICING_ORDER_STATUS_ID > 0) {
			$this->order_status = MODULE_PAYMENT_CCBILL_DYNAMICPRICING_ORDER_STATUS_ID;

	}

	function update_status(){

			while (!$check->EOF){
				if ($check->fields['zone_id'] < 1) {
					$check_flag = true;
					break;
				}
				elseif ($check->fields['zone_id'] == $order->billing['zone_id']){

If there is anyone who could help or steer me in the right direction it would be very appreciated.
