Difference between admin and front controller

[jack2684]

I writing a new controller for myself. I notice that in admin contollers, there is a method like this,

public function __construct()

which seems override the __construct() method in AdminControllerCore. While in the front controllers, there is no such method. 

 

Why the admincontroller needs to override the __construct()? Is it some kind of security issue or something else? Can we just write the code in the init() method instead of __construct()?

it depends on what your admin controller needs to do.  For example, if you are displaying a list of data from the database (like customers or orders), then you would use __construct to define where the data would be pulled from.

it's not a "override"

if you use __construct function, it will be used also with __construct of parent element

it's great feature in php , you can define own object params there, define some actions etc.

Can I implement those thing in "public function init()"?

You are asking me if you can use init() without stating what you are trying to do, so I can't answer your question.

 

I would suggest you find a similar admin controller (that does what you are looking to do) and do what it does.

in my opinion you can, and this is correct function for such things.

__construction it's a constructor

The "__construct" was introduced in PHP5 and it is the right way to define your, well, constructors (in PHP4 you used the name of the class for a constructor). You are not required to define a constructor in your class, but if you wish to pass any parameters on object construction then you need one.
