Help in creating new module

[omega13a]

I'm trying to write a new order total module. However, it just won't install from the admin panel. >_< I click install and nothing happens. :huh: Can anyone help me here? :sweating: Here's the code if it is off any help:

 

<?php
class ot_authorization_code
{
var $code;
var $title;
var $description;
var $enabled;
var $sort_order;
var $output;
var $deduction;
var $check;

function ot_authorization_code()
{
	$this->code = "ot_authorization_code";

	$this->title = 'Pre-Registered Class(es)';
	$this->description = "If you are signing up as part of a mass registration, please enter your authorization code";
	$this->enabled = true;
	$this->sort_order = 741;
	$this->output = array();
}

function process()
{
	global $PHP_SELF, $order, $currencies;

	$order_total = $this->get_order_total();
	$od_amount = $this->calculate_credit($order_total);

	$tod_amount = 0.0;
	$this->deduction = $od_amount;

	if ($od_amount > 0)
	{
		$order->info['total'] = $order->info['total'] - $od_amount;
		$this->output[] = array('title' => $this->title . ':', 'text' => '<b>-' . $currencies->format($od_amount) . '</b>', 'value' => $od_amount);
	}
}

function check()
{
	$check_query = tep_db_query("select configuration_value from " . TABLE_CONFIGURATION . " where configuration_key = 'MODULE_ORDER_TOTAL_AUTHORIZATION_CODE_STATUS'");
	$this->check = tep_db_num_rows($check_query);
	return $this->check;
}

function keys()
{
	return array(
		'MODULE_ORDER_TOTAL_AUTHORIZATION_CODE_STATUS',
		'MODULE_ORDER_TOTAL_AUTHORIZATION_CODE_SORT_ORDER',
	);
}

function install()
{
	tep_db_query("insert into " . TABLE_CONFIGURATION .

Your files must be named ot_authorization_code.php - you *must* have a corresponding language file.

 

It installs fine for me, but I have not tested it further.

 

Please remember to put the osCommerce copyright notice and your own copyright notice in the files :)

 

Please be sure to upload it as a contribution.
