I have

News.class.php and NewsTable.class.php

i would like edit method getTitle(). In News.class.php i add:

public function getTitle()
{
    return $this->title . "aa"; //line 35
}

but i have error:

Notice: Undefined property: News::$title in localhost/new/lib/model/doctrine/News.class.php on line 35

i if change for:

public function getTitle()
{
    return $this->getTitle() . "aa"; //line 35
}

then site not show.

if change:

public function getTitle()
{
    return $this->body . "aa"; //line 35
}

this work OK! How can i fix?

Use $this->get('title'). That gets the title from the Doctrine model class. :)

public function getTitle() {
  return $this->get('title').'aa';
}
