With the current version of ClassifiedEngine, when you search a product, you can sort by price from by highest to lowest.

But can we sort products from the lowest price to the highest? The answer is YES.

Here is what your result looks like in the front end:

sort price

To do this, add these following codes into child-theme/functions.php file:

add_filter( 'ce_ad_custom_sort_args' , 'ce_ad_custom_sort_args_child' );

function ce_ad_custom_sort_args_child($args){

   $args['price_asc'] = array( 'label' =>   __("Price Asc", ET_DOMAIN),  'key'   => __("price_asc", ET_DOMAIN));

   return $args;


add_filter( 'pre_get_posts', 'pre_get_posts_child', 112 );

function pre_get_posts_child($query) {
   global $wpdb,$wp_query,$et_global;
   if ( !$query->is_main_query()  ) return $query;
   $orderby    =    ce_get_ad_orderby();

   if ($orderby == "price_asc"){



       add_filter( 'posts_orderby', 'posts_orderby_asc');


    return $query;


function posts_orderby_asc() {

global $wpdb;

// return "{$wpdb->postmeta}.meta_value DESC";

return "{$wpdb->postmeta}.meta_value + 0 ASC, {$wpdb->posts}.post_date DESC";

      Hi Momo,

      Actually, we haven’t had any plan to directly implement in our theme yet. However, you can just follow this tutorial then it’ll work.

        Hello An,
        As we are now in 2016, I would like to understand why this option has not been implemented to the theme ?
        I guess you know this should not be an option but an integrated feature for a classified theme.
        I don’t really understand why instead of implementing this small piece of code to the main theme you ask your customers to add this code by their own in their theme.
        As you already have the code, for you it’s not a pain to implement it definitively in the theme.
        You are asking all your customers to follow the tutorial when for you it requires to do it only 1 time.
        Please understand it’s not a disrespect asking you that but as now I am the owner of your theme, I would really appreciate to understand why you ask us to follow your instructions instead of simply implementing good things like that knowing you care of your customers.
