Question

I have been able to create simple MVC app to display the form and use information from the database. [ so sql I use SELECT ].

However, when I use ‘update’ or ‘delete’ the data in the database stay the same. I don’t understand!?!

[ I use controller.php call model and pass id to match with the row in the table]

1. I check data that pass in there, and it did echo the value of id.

2. The page I load from the controller that call method in model has complete without the error (it could be that the syntax is right, but logic is wrong).

3. so i start to change sql statement to SELECT and it gives me the value that match with $id param’

I don’t understand? any clue?

 $query = JFactory::getDbo()->getQuery(true);

 $db =& JFactory::getDBO();
 $query = "DELETE FROM `menutables`  WHERE `id2` = $id ";


$db->setQuery($query);
$db->query(); // this line I also take it out to test, it is fine but no data change either

Do you try to modify a Joomla database or a personal one?
