The query filter

Hi!

I really wanted to show in Similar posts only those products of the online store that are available. The availability of the item is defined in the custom field ‘sklad_1’.

I know how to modify a query to get products with the required custom fields. But I didn’t want to change the plugin files. And to change (filter) the query, you need a filter on it. I temporarily changed the plugin file YARPP_Core.php and added a filter to the query in the function display_related():

$wp_query->query(
                apply_filters('yarpp_wp_query', array( // malferov - apply_filters (see functions.php of theme)
                    'p'         => $reference_ID,
                    'orderby'   => $orders[0],
                    'order'     => $orders[1],
                    'showposts' => $limit,
                    'post_type' => (isset($args['post_type']) ? $args['post_type'] : $this->get_post_types()),
                ), $args)
            );

And in the functions file.php themes added filter:

/*
    * Filter wp_query of YARPP Plugin
    */
    function yarpp_custom_wp_query($args) {
        $meta_query = array(
                array(
                    'key' => 'sklad_1',
                    'value' => 0,
                    'compare' => '>',
                )
        );

        $args = [
            'post_status' => 'publish',
            'order' => $args['order'],
            'orderby' => $args['orderby'],
            'p' => $args['p'],
            'post_type' => $args['post_type'],
            'showposts' => 6,
            'meta_query' => $meta_query,
        ];

        return $args;
    }
    add_filter( 'yarpp_wp_query', 'yarpp_custom_wp_query');

Then, in the Admin panel in the Plugin settings, I set the number of similar posts to 12 (so that at least 6 of them meet the requirement to be available on stock).

I get it! ??

And finally, why I wrote this post. Please add a filter for $wp_query to the display_related() function in future releases so that user can modify the $wp_query without changing the plugin’s files.

Thank you!
