Categories listing - search and sort

Hello,

You have to create a Module Filter specific for your Category listing, with only filter entries (HikaShop Configuration, Display dropdown => Filters) restricted on your required Category (if needed).
And in your required Item Menu, your category listing settings and activate in Product features display part, the Filters options.

Follow my configuration, especially red bordered part, but maybe you have to adapt to your relative needs.

Hi,

Unfortunately, there is no already available mechanism for categories listings.

Now, if you want to build your own filter system for categories, that's totally possible. You need two things:
1. create a module, which would allow the user to apply some filtering with dropdown, or input field, or other interfaces.
2. a plugin of the type "hikashop" implementing the onBeforeCategoryListingLoad event:
www.hikashop.com/support/documentation/6...eCategoryListingLoad
This event will be called each time HikaShop loads a listing of categories. First, you want to check that you're on a categories listing menu by checking the parameters. Then, you can read parameters relative to your module interface (for example, if you have a link to the same page with an extra parameter ?categorysearch=xxx added to it for a search on the category name with the text "xxx"), and then you can add custom conditions to the $filters parameter of the event to actually apply the filter to the loading of the categories. For example:

public function onBeforeCategoryListingLoad(&$filters) {
 // ....
 $search = hikaInput::get()->getString('categorysearch');
 if(!empty($search)) {
  $db = JFactory::getDBO();
  $filters[] = 'a.category_name LIKE '.$db->quote($db->escape('%'.$search.'%'));
 }
}
