I get a fatal error when trying to use the javascript helper in cakePHP.

  • 0

I get a fatal error when trying to use the javascript helper in cakePHP. I am following this document, I have added jquery to my default layout: 

<?php 
     <head>
     echo $this->Html->script('jquery');
     ....
     </head>

     <body>
     .....
     echo $this->Js->writeBuffer(); // Write cached scripts
     </body>
?>

I have also added the helper to my array of helpers in my controller:

<?php
     public $helpers = array('Js' => array('Jquery'), 'Html', 'Form');

When I open the page with just these set it is fine and works, however if I add these lines of code to this function and then refresh the page:

 public function index()
 {
   ....
   $this->Js->get('#draggable');
   $this->Js->draggable();
 }

Cake produces the error Error: Call to a member function get() on a non-object.

Any ideas as to what I am doing wrong?

    Helpers are meant to be used in views, not in controllers, hence the error. Move the code from your index() method to the index view and the error should disappear.
