PD_Steve question: on Option Type Feature module

[[email protected]]

I have a question about the instructions for your Product Attributes - Option Type Feature. It is for the instructions for the file: /catalog/includes/classes/shopping_cart.php

 

These are the instructions I'm confused about:

______________________________________________________________

FIND: (around line 88)

 

$products_id_string = tep_get_uprid($products_id, $attributes);

$products_id = tep_get_prid($products_id_string);

 

if (is_numeric($products_id) && is_numeric($qty)) {

$check_product_query = tep_db_query("select products_status from " . TABLE_PRODUCTS . " where products_id = '" . (int)$products_id . "'");

$check_product = tep_db_fetch_array($check_product_query);

 

if (($check_product !== false) && ($check_product['products_status'] == '1')) {

 

REPLACE with

 

$products_id = tep_get_uprid($products_id, $attributes);

______________________________________________________________

 

Because in my file it has some extra code which I pasted below:

______________________________________________________________

$products_id_string = tep_get_uprid($products_id, $attributes);

$products_id = tep_get_prid($products_id_string);

 

$attributes_pass_check = true;

 

if (is_array($attributes)) {

reset($attributes);

while (list($option, $value) = each($attributes)) {

if (!is_numeric($option) || !is_numeric($value)) {

$attributes_pass_check = false;

break;

}

}

}

 

if (is_numeric($products_id) && is_numeric($qty) && ($attributes_pass_check == true)) {

$check_product_query = tep_db_query("select products_status from " . TABLE_PRODUCTS . " where products_id = '" . (int)$products_id . "'");

$check_product = tep_db_fetch_array($check_product_query);

 

if (($check_product !== false) && ($check_product['products_status'] == '1')) {

______________________________________________________________

 

Any idea what to do here? I'm not sure why my file has extra code, as I have not installed any other modules yet.

 

Thanks so much and I'm really excited about getting this module up and running! Sorry to post this out here, this system would not let me send you a personal message.
