Question

i have:

  public function executeTest(sfWebRequest $request)
  {
            $query = Doctrine_Query::create()
            ->from('Messages')
            ->where('id = ?', $id);
            $query->fetchArray();
  }

i did function in lib/model:

        public function newfunction($id)
    {
            $query = Doctrine_Query::create()
            ->from('Messages')
            ->where('id = ?', $id);

            return $query->fetchArray();

    }

and now have:

  public function executeTest(sfWebRequest $request)
  {
         $this->newfunction($id);
  }

but i have error:

sfException: Call to undefined method messagesActions::newfunction.

if :

  public function executeTest(sfWebRequest $request)
  {
         $this->newfunction($id);
  }

i have

Fatal error: Call to a member function newFunction() on a non-object in

What can I do?

Answer 1

I’m assuming you created newFunction in lib/model/MessagesTable.class.php.

$this->newFunction() won’t work, because $this refers to the current action instance, not your model’s table. You need to use either:

Doctrine_Core::getTable("Messages")->newFunction($id);

or

MessagesTable::getInstance()->newFunction($id);

they both do the same thing, so it’s just a matter of preference.

Also, you do not set a value for $id in your action’s code.
