Only Include In-Stock WooCommerce Products in Grid

Step 1:

Get your grid’s ID.

Step 2:

Add the following code to your theme’s “functions.php” file, modifying the number “1” with your grid’s ID.

add_filter('essgrid_modify_posts', 'eg_mod_posts', 10, 2);
 
function eg_mod_posts($posts, $grid_id) {
 
    // only process if Grid ID equals "1"
    if($grid_id == 1) {
 
        $products = array();
 
        foreach($posts as $post) {
 
            $id = $post['ID'];
            $meta = get_metadata('post', $id);
 
            if($meta['_stock_status'][0] == 'instock') {
 
                $products[] = $post;
 
            }
 
        }
 
        return $products;
 
    }
 
    return $posts;
 
}
