Navigation:  Components > Hook > Helper

This Hook used to register helper.
 
Step1: Register Call call back. See below format:
 
App::Module('Hook')

   ->setHookName("Helper")

   ->setAction("register_helper")

   ->Register(Call Back Class Name, Call Back Function Name);

 

 

Step 2: Register resource in Call back function:

In call back function we return an array with Helper information like below
 

$srcpaths[] = array(

   'type'=>Name,

   "'path"=>Path

);
 
 

 

Call a helper:
We call a component helper like bellow:
 
App::Component(ComopnentName)->Helper(HelperName);
 
following example:
App::Component('appStore')->Helper('Data')->getPrice();

 

 

See below example:
class Component_Appstore_Register extends appRain_Base_Component
{
   public function init(){
 
       App::Module('Hook')
           ->setHookName('Helper')
           ->setAction("register_helper")
           ->Register(get_class($this),"register_helper");
 
   }
 
   public function register_helper()
   {
       $srcpaths = Array();
       $srcpaths[] =   array(
          'name'=>'Data',
          'path'=>$this->attachMyPath('helpers/data.php')
       );
      return $srcpaths;
   }
}
