Question

Answer 1

+1 A:

I'd say the errors are pretty self explaining. What exactly is your problem?

In view.html.php you have the variable $item and try to access the properties $item->idcuisine and $item->idcategory but actually, $item is just a string

 $item = 'item';

and hence cannot have properties.

In listrestaurant.php your class does not seem to have a property search or filter_order. You don't define them in your class, but I don't know about the parent class JModel.

@anwar: I don't know your application. You have to assign a valid object to `$item`.

this is the parent class

anwar 2010-05-11 08:38:51

@anwar: No its not. It is the same class as above. Also you should not answer your own question if it is not a real answer. Anyway you should know which properties are available in your class and if it says `search` is not available, than it isn't and you cannot use it.
