Default Shipping Method Problem

[toeyt]

Zen Cart 1.3.7
Database Patch Level: 1.3.7
Server OS: Linux 2.6.19.2-UP
Database: MySQL 4.1.20-max-log
HTTP Server: Apache
PHP Version: 4.3.11 (Zend: 1.3.0)

I have two shipping modules setup:
1. free shipping options with total >= £100.00
2. table rate

The problem I found is:

When I have £100.00 or more in the shopping cart and go to check out, both shipping methods show up and the free shipping method is selected as default, which is correct. Then I go back to the shopping cart and remove some items to make the total amount less than 100. After that, I go to check out again, and only table rate shows up. However, it is not automatically selected as default. If I click continue without selecting it, it takes me back to the page again without any error message.

Also, if I have less than £100.00 in the shopping cart and go to check out, only table rate shows up, and it is selected as default. This is correct. Then I go back to the shopping cart and add more items to make the total amount more than £100. After that, I go to check out again, and both shipping method show up, but the table rate is still selected as default. It should default to free shipping instead.

Thanks,

At the present time, once a shipping method is selected, it remembers that selection until the customer changes it or completes checkout or logs out.

If the selection is not valid for checkout, the customer is not allowed to complete checkout without selecting a valid option.

Will there be any fixes?
Or, this is how it suppose to work...

[DrByte]

There may be a "fix" to ensure that an error message is properly displayed if the previously-selected choice is no longer valid ... I'm surprised you're not seeing any error/warning about that.

What template are you using?
What customizations have you made to the templates used for checkout pages?

[toeyt]

I have my own template. But I use default tempaltes for all checkout process. There is no customization on the checkout process.

I also tested on a demo site, http://demo.opensourcecms.com/zencart/ , and I got the same result.

I looked at the header.php of checkout_shipping page, but I couldn't find any code that sends out error. Not sure if I look at the right place...

While waiting for the fix, I am planing to make a hack to it. I am thinking that if the selected shipping module is no longer exist, I will default to the cheapest one. (This is what my client wants.):

on line 172 of /includes/modules/pages/checkout_shipping/header.php.

 
// if no shipping method has been selected, automatically select the cheapest method.
// if the modules status was changed when none were available, to save on implementing
// a javascript force-selection method, also automatically select the cheapest shipping
// method if more than one module is now enabled
  if ( !$_SESSION['shipping'] || ( $_SESSION['shipping'] && ($_SESSION['shipping'] == false) && (zen_count_shipping_modules() > 1) ) ) {
   $_SESSION['shipping'] = $shipping_modules->cheapest();
  } else {
 $x3 = false;
 foreach ($quotes as $x1) {
  if ($x1["id"] == $_SESSION['shipping']['module']) {
   $x3 = true;
  }
 }
 if (!$x3) {
  $_SESSION['shipping'] = $shipping_modules->cheapest();
 }
}

Does it look ok? Is it the right place to do the hack?

Thanks

I too am looking for a fix/solution to this issue.

Toeyt, did your fix work?

I also noticed that if changing the address (on the checkout step 1 page), to one with a different shipping zone, the cheapest new shipping method is automatically selected. I'm going to look at this code now and see if it can be copied for use elsewhere.

I tested it in test environment, and it worked fine.
But I didn't implement it on the live site.
The owner of the site didn't want to hack the site. He can live with the issue...

Good luck

I've got this working on my live site and it's running fine.

Thanks for this bit of code, it's very useful. :)
