   A suggestion I have -- when creating a post, if a custom field is left blank, the empty string shouldn't be stored in the postmeta table.

   Great job so far. Looking fwd to the next release =)

   I second that! Is there a way to change this easily?

   or could you give me any help with creating a if,else string?

   The following works quite fine sometimes, but not on all the custom fields

   <?php $key="Role"; $values = get_post_custom_values($key); if ( isset($values) ) { ?><?php echo $values[0]; ?><?php } elseif ( empty($values) ) { ?><?php echo 'n/a'; ?><?php } ?>

   I have had a look at the source code of RCCWP_Post.php and compared it to the respective part of the rc-custom-field-gui.class.php file.

   From the Custom Write Panel:
   

   if (!empty($rawCustomFieldName))
   						{
   							$customFieldName = $wpdb->escape(stripslashes(trim(RC_Format::GetFieldName($rawCustomFieldName))));
   							$customFieldValue = $_POST[$rawCustomFieldName];
   
   							delete_post_meta($postId, $customFieldName);
   							if (is_array($customFieldValue))
   							{
   								foreach ($customFieldValue as $value)
   								{
   									$value = stripslashes(trim($value));
   									add_post_meta($postId, $customFieldName, $value);
   								}
   							}
   							else
   							{
   								$value = stripslashes(trim($customFieldValue));
   								add_post_meta($postId, $customFieldName, $value);
   							}
   						}
   						else
   						{
   							delete_post_meta($postId, $customFieldName);
   						}

   From the Custom Field GUI file:
   

   $meta_value = stripslashes(trim($_REQUEST[ \"$name\" ]));
         if( isset( $meta_value ) && !empty( $meta_value ) ) {
           delete_post_meta( $id, $title );
   
           if( $data[ 'type' ] == 'textfield' ||
               $data[ 'type' ] == 'radio'  ||
               $data[ 'type' ] == 'select' ||
               $data[ 'type' ] == 'textarea' ) {
             add_post_meta( $id, $title, $meta_value );
           }
           else if( $data[ 'type' ] == 'checkbox' )
             add_post_meta( $id, $title, 'true' );
         }
         else {
           delete_post_meta( $id, $title );
         }

   I am really bad with core PHP stuff. So how do I adapt the RCCWP_Post.php to delete the meta data and not create a custom field for a post if it is left blank? Any help would GREATLY be appreciated!
