Use at the beginning of your controller function:

$this->autoRender=false;

Thanks. This worked. I still get some error message like this; 

Notice (8): Undefined offset: 0 [APP\\Model\\Model1.php, line 23] 

Are those cakephp debug messages? Can I remove them by setting the debug level down?

Use the php function json_encode( ).

http://php.net/manual/en/function.json-encode.php

You can generate an associative array with the message you want, and use:

return json_encode($your_array);

Thanks. This worked. I can see the json message in the HTTP response. But I still have a problem. When I look at the HTTP response, it is full of other HTML code besides the json message. How can I remove the other HTML code and leave behind only a clean json message? 

Thank you.

I have a controller which takes in an id and checks whether this id exists inside the Model. If it does not exist, I would like the controller to return a validation error message "id not found" in json when it returns the HTTP response. This controller takes in a normal HTTP POST which is not in json.

How can this be done in Cakephp 2.4.5?

My controller code looks something like this;

public function controller_function($id=null)  {      if ($this->request->is('post'))       {         $field=$this->request->data['Model']['field'];         $Model_id = $this->Model->findFieldID($field);         if (empty($Model_id) ) //record not found. Return validation error         {             //Send validation error back in JSON. How??         }      }  }
