Stock by Attribute v4.0 addon for v1.3.5-1.3.9

[godfogger]

Hey guys and gals, I am a noob, (As every one sighes!! Another one!!) Sorry!! I am stuck in a pickle and I'm trying to dig my way out.
After installing ZC 1.5, configured the cart to be fully operational with all my needed settings and looks, I have found that I need a module like Stock by Attribute to help me keep track of multiple attributes in my inventory. This scenario would fall in line with the whole t-shirt sizes and colors attributes analogy very similarly. My problem is that I have already started loading products, yet our catalog menu and options have just trippled over night, which is going to cause a major headache as we grow. Now that I'm to this point, going back to a fresh install to add this module would set me back weeks. Is there anyway I can get some help figuring out how to make changes to the php files without starting from scratch? I would greatly appreciate it!
P.S. I started to do a fresh install on a seperate server if it helps to cut corners, then relocate. Whichever is easier!

Using ZENCART 1.5
Would like to implement "Stock by Attributes 4.7 multi add"
Unix based server (justhost.com)

PROBLEM:
I am selling Women's Shorts in two sizes, and the stocking level for each is unique.
The attributes are only two: (Size small and Size medium).

Is there a simple way to do this? When I say simple, I mean can I use features already built into V1.5 ?

Thank you for your time.

I did all the changes, but then I just get a white store. The admin-area works fine, the Stock by Attributes is there in my 1.5, but my store is just plain white.
Anyone knows why that is?

Did you merge the code or copy it? In order for this to work, you must merge the code and merge only those sections labeled for stock by attributes. The problem here is that the code sections were not labeled in some of the files, and it gets a little tricky - but still doable.

Toneklone,

Did you resolve this issue? If so how? I am having the same problem and I did merge the files. I'm pretty sure the issue is with the file: admin/includes/functions/general.php

But you have to restore all the original ZC files that were modified or overwritten before the white screen returns to normal. I checked my site each time I uploaded a merged file and the one stated above was what sent my site to a white screen. Just restoring that file didn't fix it though.

If anyone else could help it would be much appreciated. Thank you.

ATTENTION: Restock Feature has been FIXED!!!!

Sorry for the caps, but I am just too excited

I really had to get the functionality of this feature to start working, well because, a typical order for my store might contain numerous products, and having to manually edit the stock for each product when I deleted a large order was not practical.

So without further Adieu! -

In \admin\includes\functions\general.php look for the following code:

function zen_remove_order($order_id, $restock = false) {
    global $db, $order;
    if ($restock == 'on') {
      $order = $db->Execute("select products_id, products_quantity
                             from " . TABLE_ORDERS_PRODUCTS . "
                             where orders_id = '" . (int)$order_id . "'");

      while (!$order->EOF) {
        //restored db
        $restored_attributes = $db->Execute("select pa.products_attributes_id    
                                              from ".TABLE_ORDERS_PRODUCTS_ATTRIBUTES." opa, ".TABLE_PRODUCTS_ATTRIBUTES." pa
                                              where opa.orders_id='".(int)$order_id."'
                                              and opa.products_options_id = pa.options_id
                                              and pa.options_values_id = opa.products_options_values_id
                                              and pa.products_id='".(int)$order->fields['products_id']."'
                                              ORDER BY pa.products_attributes_id ASC
                                            ");
        while(!$restored_attributes->EOF) {
          $attr_array[] = $restored_attributes->fields['products_attributes_id'];
          $restored_attributes->MoveNext();
        }
        //echo implode(',', $attr_array);die;
        $db->Execute("update ".TABLE_PRODUCTS_WITH_ATTRIBUTES_STOCK." 
                        set quantity = quantity + " . $order->fields['products_quantity'] . " 
                        where products_id = '" . (int)$order->fields['products_id'] . "'
                        and stock_attributes = '".implode(',', $attr_array)."'
                      ");
        $db->Execute("update " . TABLE_PRODUCTS . "
                      set products_quantity = products_quantity + " . $order->fields['products_quantity'] . ", products_ordered = products_ordered - " . $order->fields['products_quantity'] . " where products_id = '" . (int)$order->fields['products_id'] . "'");
        $order->MoveNext();
      }
    }

And replace with...

function zen_remove_order($order_id, $restock = false) {
    global $db, $order;
    if ($restock == 'on') {
      $order = $db->Execute("select orders_products_id, products_id, products_quantity
                             from " . TABLE_ORDERS_PRODUCTS . "
                             where orders_id = '" . (int)$order_id . "'");

      while (!$order->EOF) {
        //restored db
        $restored_attributes = $db->Execute("select pa.products_attributes_id    
                                              from ".TABLE_ORDERS_PRODUCTS_ATTRIBUTES." opa, ".TABLE_PRODUCTS_ATTRIBUTES." pa
                                              where opa.orders_id='".(int)$order_id."'
                                              and opa.products_options_id = pa.options_id
                                              and opa.products_options_values_id = pa.options_values_id
					      and opa.orders_products_id='".(int)$order->fields['orders_products_id']."'
                                              and pa.products_id='".(int)$order->fields['products_id']."'
                                              ORDER BY pa.products_attributes_id ASC
                                            ");
        while(!$restored_attributes->EOF) {
          $attr_array[] = $restored_attributes->fields['products_attributes_id'];
          $restored_attributes->MoveNext();
        }
        $db->Execute("update ".TABLE_PRODUCTS_WITH_ATTRIBUTES_STOCK." 
                        set quantity = quantity + " . $order->fields['products_quantity'] . " 
                        where products_id = '" . (int)$order->fields['products_id'] . "'
                        and stock_attributes = '".implode(',', $attr_array)."'
                      ");
        $db->Execute("update " . TABLE_PRODUCTS . "
                      set products_quantity = products_quantity + " . $order->fields['products_quantity'] . ", products_ordered = products_ordered - " . $order->fields['products_quantity'] . " where products_id = '" . (int)$order->fields['products_id'] . "'");
        unset($attr_array);
	$order->MoveNext();
      }
    }

But just a little background and forewarning, I am by no means a programmer, just a noobie, but proficient computer nerd who has had a little background in programming back in college. I sat down for the past 12 hours trying to dissect the logic of tying the line items of the ORDERS_PRODUCTS table (which records each of your unique products sold and in what quantities) to the PRODUCTS_WITH_ATTRIBUTES_STOCK table (which contains your master list of stock for each unique attribute of your product inventory) in the zen-cart database, and realized that the arguments utilized were not specific enough to appropriately identify tie the two tables together accurately.

Furthermore, $attr_array needs to be unset after each iteration, or else data just gets appended to the end of it, causing the whole function to simply not work.

PLEASE NOTE:

This needs more testing and input from the rest of you guys who use this module, because my store's attributes are set up where the only unique attribute I use is color.

So if your store's products are similar to mine, I'm sure that the fix above will work, but if you have multiple attribute combinations (such as size and color), then please test cautiously, and provide your feedback. From looking at the code, I believe it should work in all scenarios...but I can't be for certain.

Also, PLEASE test with caution!!! I would suggest creating a few dummy orders and taking note of your quantities before and after placing your dummy order then monitoring the stock levels after you delete the dummy order and choose to restock the items! It should go without saying, but...obviously don't test this on real live orders :)

Hopefully this helps out a lot of you out there, and this code (or at least the logic to make the restock feature work) make it to the 1.5 version of SBA!

[RoboPhung]

Sorry, also important to note for my above solution, this is for ZC 1.3.9h only! I don't have any experience with 1.5 and don't know if the code has changed much, if any, in 1.5...so I can only guarantee this to be working with the latest verion of SBA for ZC 1.3.9h.

Any suggestion on how I can fix this???

Thanks in advance

[milobloom]

I searched my store for pa1 and narrowed the problem. Is there something I can comment out to remove this problem??

Dr Byte once said

"WHERE pa1.products_attributes_id IN ()"
You're telling it to lookup a products_attributes_id in the list of values specified inside the parentheses, but your list is empty, thus you're creating a MySQL syntax error. Hence the error message.

So I see the 2 places... What can I do now?

WHERE pa1.products_attributes_id IN ($atr)

Is the problem..
