    // if our nonce isn't there, or we can't verify it, bail 
    if(!isset($_POST['meta_box_nonce']) || !wp_verify_nonce($_POST['meta_box_nonce'], 'my_meta_box_nonce')) return;

    // now we can actually save the data 
    $allowed = array( 
     'a' => array(// on allow a tags 
      'href' => array() // and those anchords can only have href attribute 
     )

    // Probably a good idea to make sure your data is set 

    if(isset($_POST['meta_box_video_embed'])) 
     update_post_meta($post_id, 'meta_box_video_embed', $_POST['meta_box_video_embed']);

Answer 1

to:

function meta_box_video() 
{ 
    add_meta_box('video-meta-box-id', 'Video Embed', 'meta_box_callback', 'post', 'normal', 'high'); 
} 

Należy określić page nie post.

function meta_box_video() 
{          // --- Parameters: --- 
    add_meta_box('video-meta-box-id', // ID attribute of metabox 
        'Video Embed',  // Title of metabox visible to user 
        'meta_box_callback', // Function that prints box in wp-admin 
        'page',    // Show box for posts, pages, custom, etc. 
        'normal',   // Where on the page to show the box 
        'high');   // Priority of box in display order 
} 

Spójrz na Codex for add_meta_box(). Przykłady są bardzo pomocne. Część, którą jesteś zainteresowany, jest pod "Parametrem". Czwarty parametr pozwala określić, czy chcesz mieć metabox na stronach, posty itp.
