I'm registering multiple metaboxes in my write posts panels. In functions.php:

```
$meta_boxes[] = array(
    'id' => 'products',
    'title' => 'Products',
    'pages' => array('post', 'page', 'link'), // multiple post types, accept custom post types
    'context' => 'normal', // normal, advanced, side (optional)
    'priority' => 'high', // high, low (optional)
    'fields' => array(
        array(
                        'name' => 'something',
            'id' => $prefix . 'something',
            'desc' => 'some description',
            'type' => 'checkbox'
              ),
                 //continue with other fields
             )
           );

//another metabox 
$meta_boxes[] = array(
    'id' => 'customers',
    'title' => 'Customers',
//etc...

```

I'm able to get all the values of fields in a post using:

```
$custom_field_keys = get_post_custom_keys();
foreach ( $custom_field_keys as $key => $value ) {
    $valuet = trim($value);

    if ( '_' == $valuet{0} )
        continue;
        echo $value . ":<br />";
        echo get_post_meta($post->ID, $value, true) . "<br/><br/>";
}

```

How can I get the names and values of all fields within a metabox that I specify. For example get all values of fields in metabox id "products".
