    Hi Im trying to use php to display a list of a type of custom post. I created the post type using MB with an id of "course" and tried using the following php
    print_r(rwmb_meta('course'));

    It's not displaying anything so am i not meant to use rwmb_meta for posts?

    Hi,

    If you are using the helper function rwmb_meta() in a custom loop (not in the post template), please add the post ID to the third argument

    rwmb_meta( 'course', '', 123 )

    where 123 is the post ID. Please read more on the documentation https://docs.metabox.io/functions/rwmb-meta/

    Maybe i didnt explain too well. First I want to show a list of a particular post type not one particular post. So i want to show a list of posts of the type "course"

    Hi,

    To show a list of a post type, please use the custom query with WP Query and add the helper function rwmb_meta() in the loop to get the field value. For example:

    // The Query
$the_query = new WP_Query( $args );
 
// The Loop
if ( $the_query->have_posts() ) {
    echo '<ul>';
    while ( $the_query->have_posts() ) {
        $the_query->the_post();
        echo '<li>' . get_the_title() . '</li>';
        echo rwmb_meta( 'course', '', get_the_ID() );
    }
    echo '</ul>';
}
wp_reset_postdata();
