Returning a value from a function in a custom field or metabox

Hello,

Is there a simple or recommended way to return a value from a function within a custom field or metabox area on the post edit screen?

For example, I tried using this approach but it doesn’t work:

function acf_load_shorturl_field( $field ) {

    // Get shorturl value
    $field = get_shorturl();

    // return the field
    return $field;

}
add_filter('acf/load_field/name=shorturl', 'acf_load_shorturl_field');

Thanks for any help or suggestions.

John

Looks like I was close. I needed to set the ‘default_value’ attribute:

function acf_load_shorturl_field( $field ) {

    // Get shorturl value
    $field['default_value'] = get_shorturl();

    // return the field
    return $field;

}
add_filter('acf/load_field/name=shorturl', 'acf_load_shorturl_field');
