 * This simply says hey if there has been text input then update but if not then
   pull from previously set option right?
 *     ```
       // validate our options
       function plugin_options_validate($input) {
       $options = get_option('plugin_options');
   
         if(strlen($options['text_string']) > 0){
       	  $options['text_string'] = trim($input['text_string']);
         }elseif(!strlen($options['text_string']) > 0){
       	  $options['text_string'] = $options['text_string'];
         }
       return $options;
       }
       ```
