Notification about undefined variable in view with MVC
Hi people!
I using phpStorm with codeigniter, when i open a view program, the phpStorm indicates error when variable is defined in controller.
Does anybody know how to solve this?

Hi there,
How it's defined in controller?
In general, IDE does not know how CodeIgniter works, how it defines variables and (in general) from what action that particular view/template will be called (rendered). Therefore, the common way to denote such variables is to typehint them in your view/template file (in PHP block, obviously, usually the very first at the top), e.g.
The variables transmitted to the view are defined in the controller via an associative array called $data like this:
Controller : $data["greeting"]="Hello"; $this->load->view('my_view', $this->data);
View : echo $greeting; // will display Hello.
There is a CodeIgniter plugin available for PhPStorm but apparently it doesn't help much to clear undefined variable errors in views code inspection when variables are defined in the controller using the $data array.
