Stocks by attributes

i accidentally uploaded the files for the stock attributes, before i installed the sql patch. Now it doesn't work when i try and install the sql.

here is the error message

1062 Duplicate entry 'STOCK_SHOW_LOW_IN_CART' for key 2
in:
[INSERT INTO zen_configuration (configuration_title, configuration_key, configuration_value, configuration_description, configuration_group_id, sort_order, last_modified, date_added, use_function, set_function) VALUES ('Show available stock level in cart when less than order', 'STOCK_SHOW_LOW_IN_CART', 'false', 'When customer places more items in cart than are available, show the available amount on the shopping cart page:', '9', '6', NULL, now(), NULL, "zen_cfg_select_option(array('true', 'false')," );]
If you were entering information, press the BACK button in your browser and re-check the information you had entered to be sure you left no blank fields.

I have tryed many things but am stuck. if you could help me that would be great!!!!

[FONT=Arial]Hi all,

[/FONT] [FONT=Arial]I have installed the products with attributes stock mod on my fresh ZenCart install. When i try to select it form the Catalog Menu i get the follwing errors...[/FONT]

[FONT=Arial]I followed the instructions ot the letter and I am using the latest release of the mod and a fresh install of the latest version of Zen Cart

It could be that the user account used to deliver web pages to users on your server (typically IUSR_xxxxx on Windows) does not have read permissions to the folder/file

public_html/newstore/admin/products_with_attributes_stock.php

Login in to your server/control panel and check the permissions on this file/folder.

hanks Kev, It was previously set to 644. I have tried it on 666 but now get the follwing error...

A file permissions error has occurred. Please check the permissions on the script and the directory it is in and try again.Bit baffled by this, thought it would be strightforward install :s

is it possible to set the quantity for all variants on every product id in one go, to say 100?

I have over 3000 products, and it seems a bit long winded to click Add Quantity For Product Variant and select all for the options and 100 for quanity!

hope that makes sense

I've looked through the code for the stock_by_attribute add-on and it looks like the verification is done at checkout. Is there any modifications that would prevent an attribute from showing in the product listing. For example if I want to allow time slots for an event but only allow qty 1 for each time slot. I don't want the customer to have to go through checkout multiple times trying to find an open time slot. I want them to be able to only see available time slots unless someone has purchased that time slot in the time it took them to complete their transaction then checkout would suffice for verifying quantity. I see a couple of queries in the attributes.php under modules that should be ok for checking quantity but I would like to here from someone with more time working with this area of the zencart to give me some feedback on preventing attributes from showing up if qty is zero or if this feature exists and I'm just missing something.

Thanks

Crin,

it sounds likike you are having a file permissions problem. Did you correctly set all the folder permissions as specified by the original Zen Cart installation instructions?

I made a single SQL statement change that does the behavior that I was looking for in my original post. After reading some posts by Grayson I think I was able to do this properly. The version of zencart I have has since replaced main_template_vars_attributes.php with just attributes.php. What I wanted to do was prevent the option from showing if the individual product-option qty was 0. I made the following modification using a LEFT JOIN and then doing a check whether the quantity is greater than zero or IS NULL within the same sql statement. If > 0 then the individual product-option has qty available. If it IS NULL then there is not an entry for this product-option and it should be using the Main Item Qty.

Code:

---

$sql=        "SELECT  pov.products_options_values_id,
        pov.products_options_values_name,
        pa.*,
        pwas.*
        FROM  " . TABLE_PRODUCTS_OPTIONS_VALUES . " pov, " . TABLE_PRODUCTS_ATTRIBUTES . " pa LEFT JOIN " . TABLE_PRODUCTS_WITH_ATTRIBUTES_STOCK . " pwas ON pwas.stock_attributes = pa.products_attributes_id
        WHERE  pa.products_id = '" . (int)$_GET['products_id'] . "'
        and    pa.options_id = '" . (int)$products_options_names->fields['products_options_id'] . "'
                and    (pwas.quantity > 0 or pwas.quantity IS NULL)
        and    pa.options_values_id = pov.products_options_values_id
              and      pov.language_id = '" . (int)$_SESSION['languages_id'] . "' " .
                $order_by;

Do any of the senior zenners see any potential problems with this? Are there other areas that could potentially be broken by this modification that I may have missed?

Thanks

I added the following to make the quantity show in select boxes if a quantity is specified for the individual attribute since some of my products will use the Item Quantity and not an individual item attribute quantity.

Code:

---

if($products_options->fields['quantity'])
{
        $products_text_to_use = $products_options->fields['products_options_values_name'] . " (" .  $products_options->fields['quantity'] . " Available)"; //yes Available is improperly hard coded
}
else
{
        $products_text_to_use = $products_options->fields['products_options_values_name'];
}
        $products_options_array[] = array('id' => $products_options->fields['products_options_values_id'],
        'text' => $products_text_to_use);
