Question

In WordPress I’m trying to create a metabox script from scratch to better understand both WordPress and PHP.

I’m having some problems with a for each loop on a multidimensional array though. I’m using PHP5.

This is the array:

$meta_box = array();    
$meta_box[] = array(
            'id' => 'monitor-specs',
            'title' => 'Monitor Specifications',
            'context' => 'normal',
            'priority' => 'default',
            'pages' => array('monitors', 'products'),
            'fields' => array(
                array(
                    'name' => 'Brand',
                    'desc' => 'Enter the brand of the monitor.',
                    'id' => $prefix . 'monitor_brand',
                    'type' => 'text',
                    'std' => ''
                )
            )
        );

And this is the for each loop:

foreach ($meta_box['pages'] as $post_type => $value) {
            add_meta_box($value['id'], $value['title'], 'je_format_metabox', $post_type, $value['context'], $value['priority']);
        }

What I’m trying to do is loop through the keys in the ‘pages’ array which is an array inside the ‘meta_box’ array and at the same time be able to use the key values of the ‘meta_box’ array.

Do I need to nest some for each loops?

Would be grateful for some pointers in the right direction so I can solve this.

Answer 1

foreach ($meta_box[0]['pages'] as $post_type => $value) {

or

$meta_box = array(...
