6. What are sessions in PHP . How to read, write and delete session in cakephp ?

Ans:

Session in PHP
PHP Sessions allows you to identify unique users across requests and store persistent data for specific users against a unique session ID. This can be used to persist state information between page requests. Session IDs are normally sent to the browser via session cookies and the ID is used to retrieve existing session data.
Reading, Writing and Deleting session in Cakephp 3.x
You can access the session data any place you have access to a request object. This means the session is accessible from:

  • Controllers
  • Views
  • Helpers
  • Cells
  • Components

In addition to the basic session object, you can also use the Cake\View\Helper\SessionHelper to interact with the session in your views. A basic example of session usage would be:

$name = $this->request->session()->read('User.name');
// If you are accessing the session multiple times,
// you will probably want a local variable.
$session = $this->request->session();
$name = $session->read('User.name');
Reading, Writing and Deleting Session Data
Session::read($key) function is used to read specific session data in CakePHP.
Session::write($key, $value) function is used to write session data in CakePHP.
Session::delete($key) function is used to delete specific session data in CakePHP.
Sample Usage
//Reading a session
$session->read('Config.language');
//Writing a session
$session->write('Config.language', 'en');
//Deleting a session
$session->delete('Some.value');

to overwrite for a specific action use below code in that action
$this->layout =”layout_name”;

42. How to include helpers in controller ?

Ans:

public $helpers = array(‘Form’, ‘Html’, ‘Js’, ‘Time’);
to in specific action use below code in that action
$this->helper[] =”helper_name”;

45. What is the use of $this->set();

Ans:

The set() method is used for creating a variable in the view file.Say for example if we write,
$this->set(‘posts’,$posts); in controller fie, then the variable $posts will be available to use in the view template file for that action.

46. What is the use of $this->set(compact());

Ans:

Using $this->set(compact()) , we can pass multiple parameters to access into the view file.

For example,
$this->set(compact(‘posts’,’users’,’reports’));
Now all these variables will be available in respective view file.

47. What are the advantages of each?which would you use and why?

Ans:

An advantage with first case $this->set(‘posts’, $posts); is that it allows two different names for the view file and controller file. For example, you could write something like $this->set(‘postData’, $posts);. Now the variable name in the view file would be $postData.

The advantage with the second approach $this->set(compact()); is easier to write, and useful especially when we are setting several variables to the view.No need to add separate line for each variable as we have with $this->set();
For example,
$this->set(compact(‘posts’,’users’,’reports’));

48. Is it possible to have Multiple validation Rules per Field in cakephp?

Ans:

Yes its possible.

49. What is wrong with the below validation rule?

 'rule' => 'notEmpty',
 'message' => 'Please Enter Email address.'
 ),
 'rule' => array(
 'rule' => 'email',
 'message' => 'Entered Email address is invalid.'
 )
)

The problem is the first rule notEmpty will never be called because email rule will overwrite it.While using multiple validation rules for the same field you must keep the rule key “unique”. In this case if we want to use multiple rules then, we can simple change the rule key names like.

'email' => array(
 'rule1' => array(
 'rule' => 'notEmpty',
 'message' => 'Please Enter Email address.'
 ),
 'rule2' => array(
 'rule' => 'email',
 'message' => 'Entered Email address is invalid.'
 )
)

Ans:

Difference between required and notEmpty

– you can change all the views extentions.

public $ext = ‘.yourext’; in specific controller like, PostsController
– you can change all the views extentions of PostsController.

public $ext = ‘.yourext’; in specific controller action like, index()
