Question

I would like to check the tbl “Is there are data exists?”. If the data isn’t exists at tbl I want to redirect to one page. How can I do without placing the same code at the actions of all controller?

if(Company::model()->exists() == false)
            $this->redirect(array('site/create'));

If you want to have this logic run before every action of every controller you can override the run method of the base controller class (usually this is named Controller; you will find it inside the protected/components/ directory).

Here’s an example of how to do it:

public function run($actionID) {
    if ($this->route != 'site/create' && Company::model()->exists() === false) {
        $this->redirect('site/create');
    }
    else {
        parent::run($actionID);
    }
}
