 * I got a custom post type, with a form for storing some data (name, url) to display
   in a template.
 * What I want to know is how can I store those values in an array?
 * An example of my code:
 *     ```
       <? function files_metadata(){
               global $post;
               $custom = get_post_custom($post->ID);
               $name = $custom["name"][0];
               $url = $custom["url"][0];
   
               echo '<input type="hidden" name="files_metadata" id="files_metadata" value="' .wp_create_nonce('files_m'). '" />'; ?>  
   
       <label>Name: </label><br/>
       <input id="name" name="name" value="<?php echo $name; ?>" />
       <label>Url: </label><br/>
       <input id="url" name="url" value="<?php echo $url; ?>" />
   
       <? function save_meta_files($post_id) {
               if (!wp_verify_nonce($_POST['files_metadata'], 'files_m')) return $post_id;
               if (defined('DOING_AUTOSAVE') && DOING_AUTOSAVE) return $post_id;
   
               update_post_meta($post_id, "name", $_POST["url"]);
               update_post_meta($post_id, "url", $_POST["url"]);
           }  
   
       add_action('save_post', 'save_meta_files'); ?>
       ```
   
 * To this I want to add something like…
 *     ```
       $url = $custom["url"][0];
       $url2 = $custom["url"][1];
       $url3 = $custom["url"][2];
   
       <input id="url" name="url[0]" value="<?php echo $url; ?>" />
       <input id="url2" name="url[1]" value="<?php echo $url2; ?>" />
       <input id="url3" name="url[2]" value="<?php echo $url3; ?>" />
   
       update_post_meta($post_id, "url", $_POST["url"][0]);
       update_post_meta($post_id, "url2", $_POST["url"][1]);
       update_post_meta($post_id, "url3", $_POST["url"][2]);
       ```
   
 * …but that actually works…
 * I hope you understand me,
    Thanks for your time
