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;
}
