Custom Query Filter in Elementor
Both post widgets and portfolio widgets come with a query control that lets you select specific posts to show in the widget. But sometimes, you need more control over the query. For those situations, there is the custom query filter, which exposes the WP_Query object and allows you to customize the query in a way you want
Setting Up a Custom Filter
In the example below, the query ID is set to my_custom_filter, so when Elementor renders the widget, it will create a custom filter based on the query ID: elementor/query/my_custom_filter
Here comes an image :
Using the Custom Filter
After you have set up the custom query filter, you can use it to modify the query in the same way that the WordPress native pre_get_posts (opens new window)hook lets you modify a query. Using the custom query filter is just like any other WordPress native action hook:
function custom_query_callback( $query ) {
// Modify the posts query here
}
add_action( 'elementor/query/{$query_id}', 'custom_query_callback' );
Examples
Multiple Post Types in a Posts Widget
function my_query_by_post_types( $query ) {
$query->set( 'post_type', [ 'custom-post-type1', 'custom-post-type2' ] );
}
add_action( 'elementor/query/{$query_id}', 'my_query_by_post_types' );
