Query Loop filtered by custom page meta_key & meta value

Hi there,

Do you mean only show posts that have a certain meta_value in the query loop?

If so, try this method:

1. add an additional CSS class for the Grid block of the query loop block, eg.my-query

2. add below PHP code:

add_filter( 'generateblocks_query_loop_args', function( $query_args, $attributes ) {

    if ( ! empty( $attributes['className'] ) && strpos( $attributes['className'], 'my-query' ) !== false ) {

        $meta_query = array(
            array(
                'key' => 'my_meta_key', //change it to your meta key
                'value' => 'my_meta_value', // change it to your meta value
            ),
        );

        $query_args = array_merge( $query_args, array(
            'meta_query' => $meta_query,
        ) );
    }

    return $query_args;
}, 10, 2 );
