Problem: Editing options not available for Order Total Modules

[borkybrown]

When I go to Modules > Order Totals in the Admin, I am no longer able to edit the settings. There is nothing displayed to the right of the Actions column. When I click on one of the items in the list, such Shipping, nothing changes on the page.

This has always worked fine, but I noticed the problem after I made some modifications to the process function of ot_shipping.php (didn't modify any other functions). However, even after I restored ot_shipping.php to it's original (unmodified) version, I still see the same behavior in the Admin.

From the shopper perspective, everything works fine and it is using the last good settings in the Admin for ot_shipping.

Any ideas on the best way to resolve this?

Okay, I just figured this out myself. It seems that if you have files in the /includes/modules/order_total directory other than the standard files and file names that ZC is expecting, it will not display the page correctly in the Admin. I just had a backup copy of ot_shipping.php in the directory named ot_shipping_orig.php and that caused the problem. Renaming the file so it doesn't start with ot_ and trying other permutations of changing the file name made no difference, it still causes the same problem.

Ah ha! You have discovered the secret of the self loading directory!

Try 1ot_somemodule.php.BAK or similar next time

Thanks for the tip, Kim!

The reason I ran into this is because I need to be able to have two different order total values to qualify an order for free shipping...one value for domestic, and one for international.

Maybe I should post this somewhere else, but...

It seems that I will need to tweak these files that make use of MODULE_ORDER_TOTAL_SHIPPING_FREE_SHIPPING_OVER:

/includes/modules/order_total/ot_shipping.php
/includes/modules/pages/checkout_shipping/header_php.php
/includes/modules/shipping_estimator.php

Can anyone confirm this, or otherwise point me in the right direction in terms of best way to enable this in ZC?

You need to customize the ot_shipping.php module for this IF where it determines what the amount is:

        if ( ($pass == true) && ( ($order->info['total'] - $order->info['shipping_cost']) >= MODULE_ORDER_TOTAL_SHIPPING_FREE_SHIPPING_OVER) ) {
          $order->info['shipping_method'] = $this->title;
          $order->info['total'] -= $order->info['shipping_cost'];
          $order->info['shipping_cost'] = 0;
        } 

You would set the module to Both ... but then need to customize:
MODULE_ORDER_TOTAL_SHIPPING_FREE_SHIPPING_OVER

to be one value for International and one value for national ...

Look at the case statement above this IF to see how National and International are determined to know which charge to apply ...

Thanks, I have tried modifying ot_shipping.php, but when testing things out with the new values, the free shipping option didn't show up at checkout when it should have.

So that led me to think that I need to modify some additional files, and I'm thinking that /includes/modules/pages/checkout_shipping/header_php.php is the culprit(?), though I need to stare at the code more.

(BTW, I'm using ZC 1.2.5)

Another way to manage Free Shipping on orders over a certain amound for 1 country is explained in this thread:
