 * Hi guys!
 * My problem is that I can not create more custom fields inside my custom meta 
   boxes.
 * I have this:
 *     ```
       function add_custom_meta_box_productos() {
           add_meta_box(
               'custom_meta_box_productos', // $id
               backend_product_metabox_title, // $title
               'show_custom_meta_box_productos', // $callback
               'products', // $page
               'normal', // $context
               'high'); // $priority
       }
       add_action('add_meta_boxes', 'add_custom_meta_box_productos');
   
           // Field Array
           $prefix_productos = 'custom_';
           $custom_meta_fields_productos = array(  
   
       array(
       'label'=> 'Label 1',
       'desc'  => 'Title',
       'id'    => 'label1',
       'type'  => 'text'
       ),
       array(
       'label'=> 'Label 2',
       'desc'  => 'Title',
       'id'    => 'label2',
       'type'  => 'text'
       ),
       array(
       'label'=> 'Label 3',
       'desc'  => 'Title',
       'id'    => 'label3',
       'type'  => 'text'
       ),
       array(
       'label'=> 'Label 4',
       'desc'  => 'Title',
       'id'    => 'label4',
       'type'  => 'text'
       ),
       );
   
       // The Callback
       function show_custom_meta_box_productos() {
       global $custom_meta_fields_productos, $post;
       // Use nonce for verification
       echo '<input type="hidden" name="custom_meta_box_nonce" value="'.wp_create_nonce(basename(__FILE__)).'" />';  
   
           // Begin the field table and loop
           echo '<table class="form-table">';
           foreach ($custom_meta_fields_productos as $field_producto) {
               // get value of this field if it exists for this post
               $meta_producto = get_post_meta($post->ID, $field_producto['id'], true);
               // begin a table row with
               echo '<tr>
                       <th><label for="'.$field_producto['id'].'">'.$field_producto['label'].'</label></th>
                       <td>';
       switch($field_producto['type']) {

       }
   
       // Save the Data
       function save_custom_meta_producto($post_id) {
           global $custom_meta_fields_productos;  
   
           // verify nonce
           if (!wp_verify_nonce($_POST['custom_meta_box_nonce'], basename(__FILE__)))
               return $post_id;
           // check autosave
           if (defined('DOING_AUTOSAVE') && DOING_AUTOSAVE)

                   return $post_id;
               } elseif (!current_user_can('edit_post', $post_id)) {
                   return $post_id;
           }  
   
           // loop through fields and save the data
           foreach ($custom_meta_fields_producto as $field_producto) {
               $old = get_post_meta($post_id, $field_producto['id'], true);
               $new = $_POST[$field_producto['id']];
               if ($new && $new != $old) {
                   update_post_meta($post_id, $field_producto['id'], $new);
               } elseif ('' == $new && $old) {
                   delete_post_meta($post_id, $field_producto['id'], $old);
               }
           } // end foreach
       }
       add_action('save_post', 'save_custom_meta_producto');
       ```
   
 * First, I create the metabox and create an array with 4 different input text. 
   But when I introduce information and clic in publish, they do not save nothing.
   The problem is that WordPress does not create the id custom field for each input
   text. This is a piece of code but I have more fields in this metabox and save
   the information properly. But, If I create new fields, these fields do not save
   the information. Any idea?
 * Thanks!

 * Hello again!
 * You have a typo in the save_custom_meta_producto() function. The foreach source
   is specified as `$custom_meta_fields_producto` but it must be `$custom_meta_fields_productos`(
   with an ‘s’ on the end). As it is, nothing is being saved, perhaps what appeared
   to be saved is residual from a previous version?
 * As long as the IDs are all unique, all the values should be saved correctly once
   the function is working properly.

 * Hi bcworkz!
 * Thanks for the correction, but I still with the problem. Finally, I will make
   it with a DEFINE.
 * But here, I need it. As you can see, the method is the same, but It does not 
   save the input text area.

 * The select saves the information properly, the input text does not. But, If I
   change the id for another that I create previously (for example ‘post_id’ that
   It’s other input from a different custom post), It works. It’s like WordPress
   does not accept new id’s.

 * I add this function to see if this was the problem but not….
 *     ```
       add_filter( 'postmeta_form_limit' , 'customfield_limit_increase' );
       function customfield_limit_increase( $limit ) {
           $limit = 1000;
           return $limit;
       }
       ```

 * No obvious problem is jumping out at me. As you say, new meta fields are not 
   being created, but it is not WP preventing this AFAIK. I think there is a subtle
   flaw in you script such that `update_post_meta()` is not called if there is not
   an existing field. I can’t identify where this flaw might be, I can only suggest
   you do a thorough trace through your code checking every variable and returned
   value is what you expect it to be and every part of any conditional only executes
   when it is supposed to.
 * Somewhere in there, you will find things are not as they should be and hopefully
   that will indicate what needs to change to make things right. Sorry I can’t give
   you a better answer, good luck with the debugging.

 * Well, I “solved” the problem with a plugin. It’s not the best way but it works.
   When I have more time I’ll find out what was the problem.
 * This design never ends jejejejejejej
