How to hide shipping option based on cart amount

[Aarto]

Hi all! I have a shipping module which is only applicable for amounts over a certain limit, I would like to alter the code a bit to hide the shipping option from the user if the cart amount is less than 500 DKK

I tried putting in code in the nidule function itself (function zipship()) and this works fine on the front-end but i get an error in the admin section every time i view shipping modules section

 

 

The code i tested (to disable module if cart anount < 500 )

 

class zipship {

var $code, $title, $description, $enabled, $num_zones;

 

// class constructor

function zipship() {

 

global $order, $cart, $cart_total;

$this->code = 'zipship';

$this->title = MODULE_SHIPPING_ZIPSHIP_TEXT_TITLE;

$this->description = MODULE_SHIPPING_ZIPSHIP_TEXT_DESCRIPTION;

$this->sort_order = MODULE_SHIPPING_ZIPSHIP_SORT_ORDER;

$this->icon = '';

$this->tax_class = MODULE_SHIPPING_ZIPSHIP_TAX_CLASS;

$this->enabled = ((MODULE_SHIPPING_ZIPSHIP_STATUS == 'True') ? true : false);

$this->num_zones = 3;

 

if ( ($this->enabled == true) && ((int)MODULE_SHIPPING_ZIPSHIP_ZONE > 0) ) {

$check_flag = false;

$check_query = tep_db_query("select zone_id from " . TABLE_ZONES_TO_GEO_ZONES . " where geo_zone_id = '" . MODULE_SHIPPING_ZIPSHIP_ZONE . "' and zone_country_id = '" . $order->delivery['country']['id'] . "' order by zone_id");

while ($check = tep_db_fetch_array($check_query)) {

if ($check['zone_id'] < 1) {

$check_flag = true;

break;

} elseif ($check['zone_id'] == $order->delivery['zone_id']) {

$check_flag = true;

break;

}

}

 

if ($check_flag == false) {

$this->enabled = false;

}

 

$cart_total = $cart->show_total();

if ($cart_total < 500) {

$this->enabled = false;

}

 

(i added these last 4 lines)

 

I get this error message in admin

"Fatal error: Call to a member function show_total() on a non-object in /var/www/web52/web/shop/includes/modules/shipping/zipship.php on line 154"

 

 

I have (as you probably realixed by now) very limited .php knowledge but it should not be very difficult to hide a shipping method based on the order amount?

 

I would be grateful for any tips/pointers

 

With kind regards
