gistfile1.txt

Metabox - sunt casutele din dreapta de la wp-admin, de la adaugare post.
        - putem adauga unele noi, in plus fata de cele existente.

<?php
   add_meta_box( $id, $title, $callback, $post_type, $context,
         $priority, $callback_args );
?>

EXEMPLU:
-------------

In functions.php:
add_action('admin_menu', 'cwp_post_options_box');

function cwp_post_options_box() {
        add_meta_box('post_info', 'Testimonial section', 'custom_post_info', 'page', 'side', 'high');
	add_meta_box('post_info', 'Testimonial section', 'custom_post_info', 'post', 'side', 'high');
}

//Adds the actual option box
function custom_post_info() {
	global $post;
	?>
