This is what I did, worked like a charm if you want to select the product listing module you want to use:
PHP Code:
$listing_module_loaded = false;
if(!$is_index_listing && $_GET['main_page'] == 'index' && !empty($cPath)){
$category_array = explode('_', $cPath);
$category_array = array_reverse($category_array);
foreach ($category_array as $c){
$listing_module_file = DIR_WS_MODULES . zen_get_module_directory("product_listing_c_$c.php");
if(file_exists($listing_module_file)){
include($listing_module_file);
$listing_module_loaded = true;
break;
}
}
}
if(!$listing_module_loaded)
include(DIR_WS_MODULES . zen_get_module_directory(FILENAME_PRODUCT_LISTING));
