I'm using Jacopo Authentication package in one of my sites, I'm extending it to add some methods and do stuff after I call its methods, I'm extending it like this:
<?php
use Jacopo\Authentication\Controllers\UserController as JacopoUserController;
class UserController extends JacopoUserController{
...
}
Now, the problem is that I need to use some methods from my BaseController, whats the best way to be able to use BaseController here? Should I just instantiate it? Maybe move as much logic as I can to a Model or Helper and duplicate a little code? Is there anything like this?
class UserController extends JacopoUserController extends BaseController{
Thank you in advance.
You can extend only one class in PHP. However you could create trait and put there functionality from Basecontroller and to use this functionality simple add use Traitname; to class that needs that functionality

I want to create a base controller class for all my controllers in Symfony, I am very new to Symfony, so don't be angry with dumb question. I am asking this question because I can't do something like this
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
class AbstractController extends Controller
{
public function __construct()
{
//...... check access level
$user = $this->getUser(); //This is not working, I don't have access to the Controller(the base class) properties
}
}
Now one of my controllers
class UserController extends AbstractController
{
public deleteUserAction(Request $request)
{
var_dump($this);// this will dump an empty class that is not instance of Symfony\Bundle\FrameworkBundle\Controller\Controller
//.... delete user
}
}
What is the best way to do this? please...
EDIT....
What I really want to do is to check whether a user privilege level is enough to access a particular action(e.g. deleteUserAction()) in a particular controller(e.g. UserController), I have a class that attach privilege level to all actions in all controllers. The check will be very efficient if it happens in a parent controller (e.g. BaseController's constructor) which is executed before UserController->deleteUserAction() but in the base controller I don't have access to $this.
I have tried voter and ACL none help my situation.
Thanks in advance.
I think second one is the best way to create your own class and use common function in it.
If you want to add some common functions of controller then it is not the proper way to add it into the Symfony default controller, Instead you can create BaseController and extend your all the controller with BaseController and your BaseController should extends Controller.
By this way the default controller of the symfony stay untouched.
simply use service controller... is shared:
http://symfony.com/doc/current/controller/service.html
I have two controllers on my website, let's call them MovieController and ReviewController.
What I want to do is to use one of MovieController's functions inside ReviewController.
The only thing I could think of is to extend MovieController instead of CController. However, it's hard for me to believe it's the right solution...
You have at least two options
1) Move the function to the main Controller, under components/Controller.php
class Controller extends CController {
2) Have another class extend from the above-mentioned main controller, and put your shared Movie/Review function inside it. Have both MovieController and ReviewController extend from this intermediate controller instead. Perhaps call it SharedController:
class SharedController extends Controller {
class MovieController extends SharedController {
class ReviewController extends SharedController {
You can:
1) create Helper class
2) use Traits/Behaviors
etc..
We are looking to build a system with core classes and the ability to extend these core classes and are looking in to using namespaces.
The problem we are having is working out if we can extend an extended class without extending the class that it extends from
For example, if we have folders and files as below
shared/classes/Entity.php
shared/classes/DatabaseEntity.php - Extends Entity.php
shared/classes/User.php - Extends DatabaseEntity.php
classes/ - Holds classes which extend from the shared classes
If we wanted to create a custom DatabaseEntity class without creating a custom User class , is this possible?
The way I understand this is that the User class will be looking in the shared namespace to extend the DatabaseEntity class but as we have extended the DatabaseEntity class, it needs to look at the top level classes directory
Example of shared/classes/User.php
namespace shared;
class User extends DatabaseEntity {
}
Example of shared/classes/DatabaseEntity.php
namespace shared;
abstract class DatabaseEntity extends Entity {
}
Example of classes/DatabaseEntity.php
namespace custom;
use shared\classes\Entity;
abstract class DatabaseEntity extends Entity {
//Some custom functionality to extend shared/DatabaseEntity
}
So if we didn't want to change the User class to say
use custom/DatabaseEntity
Then is this possible?
Hopefully that makes sense
Thanks in advance for any help
If you don't want to add to User class
use custom/DatabaseEntity
and you want to extend custom/DatabaseEntity
you may just change class declaration from
namespace shared;
class User extends DatabaseEntity {
}
to
namespace shared;
class User extends \custom\DatabaseEntity {
}
if you want to extend \custom\DatabaseEntity.
If it's not want you want to achieve I cannot understand your problem - you ask two questions.
You asked
If we wanted to create a custom DatabaseEntity class without creating
a custom User class , is this possible?
The answer is - yes, you just created it in your example. You created custom DatabaseEntity class without creating custom User class.
But if you want to achieve:
it needs to look at the top level classes directory
you need to tell User class to extend specific class - so you will need to extend using fully qualified class or import namespace using use and creating alias
I don't know if I understand you well, but you want to create CustomDatabaseEntity class that will extend DatabaseEntity and you don't want that CustomDatabaseEntity extends User class.
It's of course possible. You can create as many child classes as you want. As User class is defined that it extend DatabaseEntity class it will even don't know that you created CustomDatabaseEntity
I also think that you are using it a bit wrong. If DatabaseEntity have anything common with database and not with User itself, you should rather create Interface DatabaseEntityInterface, those two DatabaseEntity classes should implement interface
and then in User class you should pass it as constructor argument
class User {
protected $dbi;
public function _construct(DatabaseEntityInterface $dbi) {
$this->dbi = $dbi
}
}
and later you can pass to User class either class for shared folder or the one from classes
It appears that in Zend Framework 2, every controller seems to extend the AbstractActionController by default.
I was thinking if there's a way for all my controllers to extend a CustomController that in turn extends the AbstractActionController.
The purpose of this CustomController, is to do checks like whether a user is authorized to access my other controllers or not and also may be generate menu navigation.
Is this still a good idea and if so, will doing this work?
**IndexController.php**
class IndexController extends CustomController {
}
**CustomController.php**
class CustomController extends AbstractActionController {
}
Thanks,
Of course you can extend a base class and it will work.
Is it a good idea ? It really depends on your project.
For authentication and permission check, you could also use a module like ZfcRbac or BjyAuthorize
For navigation, there is spiffy-navigation
If you use php 5.4+, Traits can also be an alternative to inheritance
In my application I have got a main controller in which I have a few methods. One of them checks if the user is logged in and if not it redirects the user to login form etc.
class FA_Controller_Auth extends Zend_Controller_Action {
public function preDispatch() {
//chceck user is login
}
}
aand all controllers extend from this main class
IndexController extends FA_Controller_Auth{}
but now I am building multi payment gatwey from Zend_Payment_Controllerso Payment_GatewayController should extend from Zend_Payment_Controller. But I need to chack if the user is logged in or not and I am looking for somthing like multi extend
Payment_GatewayController extends Zend_Payment_Controller, FA_Controller_Auth
I know there is no way to use multi extend class in PHP but maybe there is a better way to do this, action helper or plugin to check authorisation ?

Regards.
You can only extend one class. This is exactly why using a base controller class is considered bad practice, as it limits you somewhat. Instead you should move the logic for both checks into controller plugins instead.
