Quick Question: Whats the Best Way to Disable a Shipping Method IF..

NodsDorf · December 12, 2011

I'm using 3 shipping methods. (2.3.1)

Multi Geo Zones for orders bellow $50.00

Zone rate for Europe & Over $49.99

Table Rate for Everywhere Else Over $49.99

If the order is over $49.99 I need to disable the Mulit Geo Zone as I don't want it to display on the checkout_shipping.php page.

Can I just put an if statement on the Multi Geo Zone /includes/modules/shipping/mzmt.php page that checks the cart price?

Or should I try to do it on the checkout_shipping.php

Any help is appreciated.

Put it in multi-zones

Thanks Geoffrey,

I tried adding this to the first line of includes/modules/shipping/mzmt.php file

if ($cart->total >= 50.00) {

exit;
} else {
..... the mzmt.php code }

But this didn't work it still shows the module anyway

So then I tried without the exit;

if ($cart->total >= 49.99) {

And now I am getting class mzmt not found error

Any idea where I can stick the check at?

Here is the page code

<?php  class mzmt {
   var $code, $title, $description, $icon, $enabled, $num_zones, $num_tables, $delivery_geozone, $geozone_mode, $order_total;

	    $this->delivery_geozone = $n;
	    break;
	  } elseif ( ((int)constant('MODULE_SHIPPING_MZMT_GEOZONE_' . $n . '_ID') == 0) && ($n == (int)$this->num_geozones) ) {

check your shopping cart class ... to get the total of your cart, you need to use the funtion show_total() - there is no "total" as you put it.

and when using session arrays, you need to define them in a function like this

global $cart;

(or attach to a given list of defined globals...)

NodsDorf · December 12, 2011

Hi Monika

I printed $cart->total on the shipping.php page and it is outputting the correct value of the cart so I assumed that would work.

I'm not real sure how to acheive the other stuff you suggested.

Thanks,

Don

♥Monika in Germany · December 12, 2011

don, in that case you should try to find example code in the contribution section (for shipping modules) or google for example code ...

ypu do have at least basic php knowledge?

NodsDorf · December 13, 2011

Yes I have an okay understanding of PHP. I am having a hard time understanding why the variable $cart->total works if you echo it but you suggest I need to make another function or use the show_total() is this just because I need to use it in an array?

Anyway I do appreciate the help, I'll see if I can find another shipping module that has the code I need and try to modify it.

NodsDorf · December 13, 2011

Okay think I got it..

This seems to work

Around Line 43

Find

// class methods
  function quote($method = '') {

	 global $order, $shipping_weight, $shipping_num_boxes;
	   $combined_quote_weight = ($shipping_num_boxes * $shipping_weight);

Change To:

// class methods

  function quote($method = '') {
 global $order, $shipping_weight, $shipping_num_boxes;
	   $combined_quote_weight = ($shipping_num_boxes * $shipping_weight);
	  if ($this->order_total = $_SESSION['cart']->show_total()); {
		  if ($this->order_total >=50.00) {
		  $this->quotes = array('module' => $this-> title,
		  'error' => MAX_VALUE_EXCEEDED);
		  return $this->quotes;
		  }
	  }

Then define

MAX_VALUE_EXCEEDED error messages in all your includes/languages/xxxx/modules/shipping/mzmt.php files

Thanks to bruyndoncx for a max weight example here http://forums.oscomm...certain-weight/

It helped me sort it out.
