Show Payment module only if

[El_Heso]

Hi!

I wonder if someone can help me how to write to fix my problem.

 

I have several payment modules installed one is to pay to a company who has invoices for me but the max limt for it´s services is 5.000 incl tax so i want to hide that option of payment IF the shoppingcarts value is higher then 5.000 incl tax

 

So my question is WHERE and WHAT should i write

 

 

i use checkout.php for payment choice

code:

//Om ordern är bekräftad, aktivera betalningsmodulen

if (isset($HTTP_POST_VARS['action']) && ($HTTP_POST_VARS['action'] == 'register') && (tep_session_is_registered('customer_id'))){

require(DIR_WS_CLASSES . 'payment.php');

$payment_modules = new payment($payment);

}

 

else {

//kolla om payment-formuläret är skickat.. ändra payment till det nya valet..

require(DIR_WS_CLASSES . 'payment.php');

$payment_modules = new payment;

$payment_select = $payment_modules->selection();

 

if ((tep_session_is_registered('payment') || isset($HTTP_POST_VARS['payment'])) && (tep_count_payment_modules() > 1 )){

// load the selected payment module

if (isset($HTTP_POST_VARS['payment'])) $payment = $HTTP_POST_VARS['payment'];

//$payment_modules = new payment($payment);

} else if (tep_count_payment_modules() > 1){

$payment = 'moneyorder';

tep_session_unregister('payment');

if (!tep_session_is_registered('payment')) tep_session_register('payment');

}

 

//Om det bara finns 1 payment-modul

else if (tep_count_payment_modules() < 2 ) {

// Annars välj förskottsbetalning

$payment_select = $payment_modules->selection();

$payment = 'moneyorder';

tep_session_unregister('payment');

if (!tep_session_is_registered('payment')) tep_session_register('payment');

//tep_redirect(tep_href_link(FILENAME_CHECKOUT_CONFIRMATION, '', 'SSL'));

}

}

 

 

 

 

and the codes in payment.php:

 

<?php

class payment {

var $modules, $selected_module;

 

// class constructor

function payment($module = '') {

global $payment, $language, $PHP_SELF;

 

if (defined('MODULE_PAYMENT_INSTALLED') && tep_not_null(MODULE_PAYMENT_INSTALLED)) {

$this->modules = explode(';', MODULE_PAYMENT_INSTALLED);

 

$include_modules = array();

 

if ( (tep_not_null($module)) && (in_array($module . '.' . substr($PHP_SELF, (strrpos($PHP_SELF, '.')+1)), $this->modules)) ) {

$this->selected_module = $module;

 

$include_modules[] = array('class' => $module, 'file' => $module . '.php');

} else {

reset($this->modules);

while (list(, $value) = each($this->modules)) {

$class = substr($value, 0, strrpos($value, '.'));

$include_modules[] = array('class' => $class, 'file' => $value);

}

}

 

for ($i=0, $n=sizeof($include_modules); $i<$n; $i++) {

include(DIR_WS_LANGUAGES . $language . '/modules/payment/' . $include_modules[$i]['file']);

include(DIR_WS_MODULES . 'payment/' . $include_modules[$i]['file']);

 

$GLOBALS[$include_modules[$i]['class']] = new $include_modules[$i]['class'];

}

 

// if there is only one payment method, select it as default because in

// checkout_confirmation.php the $payment variable is being assigned the

// $HTTP_POST_VARS['payment'] value which will be empty (no radio button selection possible)

if ( (tep_count_payment_modules() == 1) && (!isset($GLOBALS[$payment]) || (isset($GLOBALS[$payment]) && !is_object($GLOBALS[$payment]))) ) {

$payment = $include_modules[0]['class'];

}

 

if ( (tep_not_null($module)) && (in_array($module, $this->modules)) && (isset($GLOBALS[$module]->form_action_url)) ) {

$this->form_action_url = $GLOBALS[$module]->form_action_url;

}

}

}

 

// class methods

/* The following method is needed in the checkout_confirmation.php page

due to a chicken and egg problem with the payment class and order class.

The payment modules needs the order destination data for the dynamic status

feature, and the order class needs the payment module title.

The following method is a work-around to implementing the method in all

payment modules available which would break the modules in the contributions

section. This should be looked into again post 2.2.
