Edit Orders v4.0 Support Thread

[burtonte]

I will try to supply as much info as I can. I am sunning zen cart 1.5.1 and I originally installed edit orders version 2.x.x. I have many many addons installed on top of the out-of-the box zen cart plus some of my own. I realize that this doesn't help but I seem to remember during the original install of zen cart and edit orders this problem arouse. I searched and searched then and found other people with the same problem when installing edit orders but no fixes. The log files complained about GetRewardPoints() as an undefined function. I assumed this was because it's not an admin function. I tried setting up the scope so admin could see this function but again I don't fully understand how php/zen cart handles scope. My assumption again was that reward points might not be calculated during an admin order entry. This was not a problem with me because I was going to use that as an excuse to drive customers to use my web site instead of phone orders but all seems to work for now. It's a new release so...we will see I'm sure

... I am sunning zen cart 1.5.1 and I originally installed edit orders version 2.x.x. I have many many addons installed on top of the out-of-the box zen cart plus some of my own. ...

Edit Orders 2.x and 4.1.x run completely different code. So what applied to a past version does not necessarily apply to the current version.

Edit Orders 2.x is not (to my knowledge) compatible with Zen Cart 1.5.x. Based on your statement of installing Edit Orders 2.x, it sounds like your store may have been upgraded "in-place" multiple times over the years. Over time this can result in lots of clutter, outdated files, and other issues. If this is the case with your site, it could be a contributing factor...

It may be in your best interest to start over with a clean install of the current version of Zen Cart 1.5.x (if the above is true). Once installed, start with a new template (designed for 1.5.x). Upgrade a "copy" of your old database and test. Only install Zen Cart plugins / modifications designed for 1.5.x (and required by your business needs). When done testing (and ensuring all required functionality works), deploy to the new site.

NOTE 1: I will not be responding further on this subject until answers to all of the questions listed in the "Posting Tips" have been supplied, answers to the questions asked in this thread have been supplied, and the response shows appropriate research (including reading the README, searching the forums, and applying known patches) has been completed.

NOTE 2: The appropriate place to change how individual order total modules operate is inside the order total modules themselves. Changes should not applied by editing the core loader / processing class "order_total.php".

Ok sorry for the missing information. I have included the differences between the vanilla zencart 1.5.1 install and the edit_orders 4.1.4 install. The responses I received caused me to go back and research what I think to be the real issue. Thanks again for your responses...

includes/classes/order_total.php

function order_total() {
global $messageStack;
if (defined('MODULE_ORDER_TOTAL_INSTALLED') && zen_not_null(MODULE_ORDER_TOTAL_INSTALLED)) {
$module_list = explode(';', MODULE_ORDER_TOTAL_INSTALLED);

reset($module_list);
while (list(, $value) = each($module_list)) {
// Fixes for when called from ADMIN
$lang_file = null;

// edit_orders v4.1.4 has this here.. causes blank screen when add new order from admin
// $module_file = DIR_WS_MODULES . 'order_total/' . $value;

if(IS_ADMIN_FLAG === true) {
$lang_file = zen_get_file_directory(DIR_FS_CATALOG . DIR_WS_LANGUAGES . $_SESSION['language'] . '/modules/order_total/', $value, 'false');
$module_file = DIR_FS_CATALOG . $module_file;
}
else {
$lang_file = zen_get_file_directory(DIR_WS_LANGUAGES . $_SESSION['language'] . '/modules/order_total/', $value, 'false');
}
if (@file_exists($lang_file)) {
include_once($lang_file);
} else {
if (IS_ADMIN_FLAG === false && is_object($messageStack)) {
$messageStack->add('header', WARNING_COULD_NOT_LOCATE_LANG_FILE . $lang_file, 'caution');
} else {
$messageStack->add_session(WARNING_COULD_NOT_LOCATE_LANG_FILE . $lang_file, 'caution');
}
}
// Moved to original position from zen cart 1.5.1 install to make add new order work in admin
$module_file = DIR_WS_MODULES . 'order_total/' . $value;

if (@file_exists($module_file)) {
include_once($module_file);
$class = substr($value, 0, strrpos($value, '.'));
$GLOBALS[$class] = new $class;
$this->modules[] = $value;
}
}
}
}

For anyone else reading this thread. Please disregard changes posted by burtonte.

In a properly configured store, moving that line will usually result in order total modules not loading from the admin interface. This includes "subtotal", "total", "tax", etc.

If order total modules are not loaded Edit Orders 4.1+ will not function correctly.

Does anyone have a copy of the plugin's v4.0.2 zip-file? I'm trying to "get a feeling" for the complexity of an upgrade to the most recent version.

[lat9]

FWIW, EO 4.1.4 installed without a hitch over the v4.0.2 "mystery version"!

I did, however, run into an issue that I'm not sure how to resolve:

SCENARIO: I've got an order total (a deduction) where the amount of the deduction is, essentially, dependent on the value of the cart/order. It uses the order-class structure to determine the overall order value and, if the order's total is less than some configurable value, then discount is not applied.

EO and my OT recalculate the deduction properly so long as the deduction doesn't change from a non-zero to a zero value! That's because, when the deduction is 0, the order-total class doesn't return that OT value as part of its modules. The order's subtotal, tax and total values are correct, it's just that the now-zero deduction doesn't get removed from the order's totals.

Any guidance would be much appreciated.
