[28-Jun-2010 08:13:15] PHP Warning: Division by zero in store/includes/functions/functions_general.php on line 1329s

which is this line of code

$zc_round = ($x1000)/($y1000);

which is not a file i've touched so far in this but i wonder if something else i install is effecting this piece of code or em i looking in the totally wrong place?

i cornered it down to this my last install of group pricing per item, i assumed everything was working but obviously not here is a link to my attempt at merging 1.39d with group pricing per item, i wonder what i did wrong

http://www.2shared.com/file/BHl-BTXw...r_item_1-.html

ok i found the file with that is the issue but i don't know what to do with it

store/includes/classes/shopping_cart.php

i'm just going back to the original code and test each line i modify till i track the issue down to the single line of code

here is the piece of code around line 1135 that is screwing everything up

    $products_array = array();
    reset($this->contents);
    while (list($products_id, ) = each($this->contents)) {
      $products_query = "select p.products_id, p.master_categories_id, p.products_status, pd.products_name, p.products_model, p.products_image,
                                  p.products_price, p.products_weight, p.products_tax_class_id,

                                  [B]p.products_group_a_price, p.products_group_b_price,
                                  p.products_group_c_price, p.products_group_d_price,[/B]

                                  p.product_is_free, p.products_priced_by_attribute,
                                  p.products_discount_type, p.products_discount_type_from
                           from " . TABLE_PRODUCTS . " p, " . TABLE_PRODUCTS_DESCRIPTION . " pd
                           where p.products_id = '" . (int)$products_id . "'
                           and pd.products_id = p.products_id
                           and pd.language_id = '" . (int)$_SESSION['languages_id'] . "'";

replaces this original code

 $products_array = array();
    reset($this->contents);
    while (list($products_id, ) = each($this->contents)) {
      $products_query = "select p.products_id, p.master_categories_id, p.products_status, pd.products_name, p.products_model, p.products_image,
                                  p.products_price, p.products_weight, p.products_tax_class_id,
                                  [B]p.products_quantity_order_min, p.products_quantity_order_units,[/B]
                                  p.product_is_free, p.products_priced_by_attribute,
                                  p.products_discount_type, p.products_discount_type_from
                           from " . TABLE_PRODUCTS . " p, " . TABLE_PRODUCTS_DESCRIPTION . " pd
                           where p.products_id = '" . (int)$products_id . "'
                           and pd.products_id = p.products_id
                           and pd.language_id = '" . (int)$_SESSION['languages_id'] . "'";
                               

any ideas? on what to do with this

ok i just merged the 2 instead of replace one for the other and it seems like everything is peachy now :D

    $products_array = array();
    reset($this->contents);
    while (list($products_id, ) = each($this->contents)) {
      $products_query = "select p.products_id, p.master_categories_id, p.products_status, pd.products_name, p.products_model, p.products_image,
                                  p.products_price, p.products_weight, p.products_tax_class_id,
                                   [B]p.products_quantity_order_min, p.products_quantity_order_units,[/B]
                                  [B]p.products_group_a_price, p.products_group_b_price,
                                  p.products_group_c_price, p.products_group_d_price,[/B]
                                  p.product_is_free, p.products_priced_by_attribute,
                                  p.products_discount_type, p.products_discount_type_from
                           from " . TABLE_PRODUCTS . " p, " . TABLE_PRODUCTS_DESCRIPTION . " pd
                           where p.products_id = '" . (int)$products_id . "'
                           and pd.products_id = p.products_id
                           and pd.language_id = '" . (int)$_SESSION['languages_id'] . "'";

Before changing code, could you make sure your Products are not setup with a Product Unit of 0 it should be 1 as you cannot but 0 ... :unsure:

sorry product unit? all the products have stock?

Edit your Products ...

Check the settings, the defaults are:

Product Qty Minimum: 1
Product Qty Maximum: 0
Product Qty Units: 1

If you have the Product Quantity Units set to 0 you will get errors ...

would this be done through the admin or through the code?

Go to your Zen Cart Admin for your store ...

Go to the Catalog ... Categories/Products ... and find a Product that this happens on and hit E for EDIT ...

Find the settings for:

Product Qty Minimum: 1
Product Qty Maximum: 0
Product Qty Units: 1

What do you have set?

Product Qty Minimum:1
Product Qty Maximum: 0 0 = Unlimited, 1 = No Qty Boxes
Product Qty Units:1

that is what i have

I tried the Apeman Training Gloves and do not get the error ... did you change something?

the apeman training gloves have the same 1,0,1 setting

and i haven't touched the code since post number 6
http://www.zen-cart.com/forum/showpost.php?p=902859&postcount=6

which solve my issue at the time and i haven't touch anything since unless adding 10 or so more mods but non of which touched this code. please look at post 5 and 6 and is there an issue with what i did you make it work. Unless the problem is elsewhere

As long as the setting are right ... you will need to speak to the folks writting the Stock by Attribute to see why the error is happening ...

It is odd, others are using it and this is not happening that I have heard of ...

well thank you like always for all the help
