    Hello,
    We are using a query inside the filter rwmb_meta_boxes to dynamic populate $posts_options in a select advanced, but the problem is that is loading in every page, admin and public.

    $posts_options = array();
$args_query = array(
    'post_type'      => 'page',
    'posts_per_page' => -1,
    'orderby'        => 'title',
    'order'          => 'ASC',
);

// The Query.
$the_query = new WP_Query( $args_query );
if ( $the_query->have_posts() ) {
    while ( $the_query->have_posts() ) {
        $the_query->the_post();
        $posts_options[ get_the_ID() ] = get_the_title();
    }
    wp_reset_postdata();
}

    How could we use this feature and not making queries every where?
    I don't see any documentation about callbacks or something similiar to populate values in a field.

    Thanks in advance.

    Hi,

    I think you can create a condition to check the area that you want to show the options, like admin area is_admin() or something else.

    $posts_options = array();
if( is_admin() ) {
    $args_query = array(
        //...
    );
    // The Query.
}

    Nice suggestion Long. That filters the query in only admin.
    Could we be more specific? in Edit page?

    I tried with pagenow global variable but in AJAX is not saving correctly.

    Hi,

    You can try to use the WP function get_current_screen() to check the current screen https://developer.wordpress.org/reference/functions/get_current_screen/

    or use this code to get the current post ID and check some cases based on the post ID

    $post_id = null;
if ( isset( $_GET['post'] ) ) {
    $post_id = intval( $_GET['post'] );
} elseif ( isset( $_POST['post_ID'] ) ) {
    $post_id = intval( $_POST['post_ID'] );
}

    Hello Long,

    I'm afraid None of your solutions works.

    get_current_screen function gives you undefined when it loads the filter:
    Fatal error: Uncaught Error: Call to undefined function get_current_screen()

    And $_GET is not working in AJAX.

    I think that the best would be to have a callback solution to load the values.

    Long, are you working in a callback so we can load dinamically the options? We need. We collapse the admin in WordPress having some blocks.

    Please work in a solution.

    Hi,

    Sorry, not yet. This case is beyond the scope support of Meta Box, it needs to create more custom code to do. You can create a service request via this contact form. I will forward it to the development team to check it and get back to you with a quote.

    It's a suggestion to add dynamic options to your plugin. Not interested in a quote.

    Dynamic fields really important, great to have feature to populate fields prior to submission in the case of MB Front-End Submission.
