How to override parent global variable

  • If I wanted to add more items to an array called $meta_box that was being created in the parents functions.php, how can I accomplish this?

PARENTS FUNCTIONS.PHP

EX. $meta_box = array(
    'id' => 'my-meta-box2',
    'title' => __('Event Information'),
    'page' => 'event',
    'context' => 'normal',
    'priority' => 'high',
    'fields' => array(
		array(
            'name' => __('Date of Event'),
            'desc' => __('Enter the date of event.'),
            'id' => 'eventdate',
            'type' => 'text',
            'std' => ""
        )
    )
);

// Add meta box
function mytheme_add_box2() {
    global $meta_box;

    add_meta_box($meta_box['id'], $meta_box['title'], 'mytheme_show_box2', $meta_box['page'], $meta_box['context'], $meta_box['priority']);
}

so in the child theme I want to add 2 more items

$meta_box = array(
    'id' => 'my-meta-box2',
    'title' => __('Event Information'),
    'page' => 'event',
    'context' => 'normal',
    'priority' => 'high',
    'fields' => array(
		array(
            'name' => __('Date of Event'),
            'desc' => __('Enter the date of event.'),
            'id' => 'eventdate',
            'type' => 'text',
            'std' => ""
        ),
       array(
            'name' => __('Time of Event'),
            'desc' => __('Enter the time(s) of the event.'),
            'id' => 'eventtime',
            'type' => 'textarea',
            'std' => ""
        ),
		array(
            'name' => __('Google Map Link'),
            'desc' => __('Enter the url for the google map link (leave blank to disable).'),
            'id' => 'eventmaplink',
            'type' => 'text',
            'std' => ""
    )
);

  • You could use the array_merge function like this:

    $new_fields = array(

       array(
            'name' => __('Time of Event'),
            'desc' => __('Enter the time(s) of the event.'),
            'id' => 'eventtime',
            'type' => 'textarea',
            'std' => ""
        ),
		array(
            'name' => __('Google Map Link'),
            'desc' => __('Enter the url for the google map link (leave blank to disable).'),
            'id' => 'eventmaplink',
            'type' => 'text',
            'std' => ""
    )
);

$meta_box['fields'] = array_merge($meta_box['fields'],$new_fields);

    I tried merging but i think there is an ordering issue , because if I merge the 2 arrays in a child functions.php its not registering

    also the above function is being used ei

    add_action(‘admin_menu’, ‘mytheme_add_box2’);

    so maybe there is something i need to do to register these new fields
