Dynamic Filter [Support Thread]

[simon1066]

Solved - All of these niggles were actually symptoms of something fairly simple (as always). The names of my options and values were in a bit of a mess because of the previous Product Filter setup I was using. I've cleaned/tidied/rationalised and all seems to work perfectly.

Hi there

I have been reading the thread to resolve the PHP Warning: strlen() expects parameter 1 to be string error but to no avail.

I have tried and done each and every thing mentioned in the thread.

I have a zen cart 1.5.1 (upgraded version) and major mods installed are: IH4, Multi cross sell and Dynamic filter. URL: http://artemisia.com/store/

The problem is when I click Add to Cart button, it gives me a blank page with the warning.

Hosting Details:

Following is what my functions_general.php file looks like:

// Return all HTTP GET variables, except those passed as a parameter
function zen_get_all_get_params($exclude_array = '', $search_engine_safe = true) {

if (!is_array($exclude_array)) $exclude_array = array();

Please help me out.

The code for 1.5.1 should be:

Thanks a lotfor the correct code.

I just made changes to my functions_general.php file.
However, the add to cart still shows a blank page with a warning.

I checked the log files and following is what it showed me:

Apparently you are running products with attribute stock, but do not have the tables installed

Hi,

Zencart v1.51
Dynamic Filter v1.2
With Multisite v0.4.2

This problem is to do with the display of the product count (next to the option value name) in the dynamic filter sidebox, the issue I believe may be related to the Multisite add-on although I can't be certain.

Category product listing pages - correct number of products listed in the center column, correct product count shown next to option value name

Featured and Advanced Search Results pages (I don't use specials, new or all) - correct number of products listed in the center column, incorrect product count shown next to option value name. The product count shows the total number of all products of all multisite sites that use the option value.

I had thought that there might be a cat_filter missing after the core file merges of the header_php.php files for Featured and Advanced Search Results pages but I have checked, and in any event the products listed in the center column of these pages are displayed correctly according to multisite settings.

It seems strange that the sidebox option values on the Category product listing pages 'count' correctly but those on the search result and featured pages do not.

Anyone have any ideas?

You are a star, thank you

[simon1066]

One thing that might be useful to include in a future release:

At the moment the the product count - I guess it should be called quantity - displayed next to the attribute remains constant, I think it would be good to have that change dynamically as attributes are selected.

I'm not sure how much work that would mean as it's beyond my capabilities.

Just a thought.
