Hi All, I installed this mod but found that regardless of the criteria selected no items were shown. I started debugging and modified the header_php.php file a bit.
The scenario is as follows.
- The file as contained in the downloads folder will only work IF YOU HAVE ATTRIBUTES loaded against your products. I do not make use of attributes but I did like the idea of having a Price and Category search on my site.
- In the downloaded version there was a reference to a ZS_table. I fixed this by changing it to the correct variable so you no longer have to change the table prefix, it will be done for you.
To install this "fix" just override the header_php.php file contained in the contribution with the following:
<?php
