In View, I can get action by using

$this->action

But, I cannot get controller name by

$this->controller

What is the proper way to get current controller in View?

回答1:

Use $this->params['controller'] to get the current controller.

You can do a debug($this->params) to see other available variables.

回答2:

You can get controller like this:

echo "<pre>controller:".$this->request->params['controller']."</pre>";

Although $this->params is shorter, $this->request->params is more autocomplete friendly. You can check the autocomplete options from this question: PHPStorm autocomplete for CakePHP custom helpers in view files

Other data about request can be taken like this:

echo "<pre>action:".$this->request->params['action']."</pre>";

echo "<pre>request:"; print_r( $this->request ); echo "</pre>";

echo "<details><summary>this:</summary><pre>"; 
      print_r( $this ); echo "</pre></details>";

Edit:
As of CakePHP 3 $this->params shortcut is removed. So you should user $this->request->params['controller'] for CakePHP 3.
http://book.cakephp.org/3.0/en/appendices/3-0-migration-guide.html#id2
Also note that first character of controller is uppercase. It was lowercase in Cakephp 2.

回答3:

$this->name also give you controller's name. Their difference with $this->params['controller'] is it's first letter capitalized

debug($this->name);
debug($this->params['controller']);

Results in:

 \app\Controller\AppController.php (line 176)

'Users'

\app\Controller\AppController.php (line 177)

'users'

回答4:

To get the current controller, Try this :$this->params['controller']

To get the current action, Try this :$this->params['action'].

回答5:

I am using cakephp 3.2

$this->params['controller'] - It is not working, showing error message as bellow..

"Missing Helper"

Following code is working properly in cakephp 3.2

$this->request->params['controller'] - Working

回答6:

To get the current,

controller: $this->params['controller']
action: $this->params['action']
arguments:$this->params['pass']

回答7:

For cakephp 3.6 and later:

Although above solutions will work but it gives deprecated warning and will not work in cakephp 4. So It is better to use the following code to get the controller name. It will work in view page and controllers as well.

$this->request->getParam('controller')

回答8:

All the other solutions are to get the controller name... I need the controller itself, so I did the following function in an AdminHelper.php called by $this->Admin->_getController('MyControllerName') into the view.ctp file

/******************************************************************
 * 
 ******************************************************************/
function _getController( $pControllerName ){
    if ( ! isset($this->controllersArray[$pControllerName]) ){
        $importRes = App::import('Controller', $pControllerName);// The same as require('controllers/users_controller.php');
        $strToEval = "\$controller = new ".$pControllerName."Controller;";
        $evalRes = eval($strToEval);
        if ( $evalRes === false ){
            throw new AppException("Eval returned an error into ".__FILE__." getController()");
        }
        $controller->constructClasses();// If we want the model associations, components, etc to be loaded
        $this->controllersArray[$pControllerName] = $controller;
    }

    $result = $this->controllersArray[$pControllerName];
    return $result;
}

Note: don't forget to declare it into the controller you'll use for example:
