Question

I’m trying to use Ajax with Zend framework. I followed this tutorial and it works. I used following code to fetch the data:

$('#button').click(function() {
      $.ajax({
          url: './ajax/review/format/json',
          dataType: 'json',
          success: function(json_data){
              alert('....');
          }
        });       
  });

The data parsed was like below:

Array ( [reviews] => Array ( [0] => Array ( [reviewid] => 3 [userid] => 1 [locationid] 
=> 3 ) [1] => Array ( [reviewid] => 2 [userid] => 2 [locationid] => 2 ) [2] => Array (    
[reviewid] => 1 [userid] => 1 [locationid] => 1 ) ) )

The Json I got was something like following:

{
    "data": {
        "reviews": [
            {
                "reviewid": 3,
                "userid": 1,
                "locationid": 3
            },
            {
               "reviewid": 2,
                "userid": 2,
                "locationid": 2
            }
        ]
    }
}

I don’t know where the “data” field comes from. I guess it relates to the way Zend parse data from controller to view, e.g. $this->view->data = array(...)

Hope I explained clearly, please help me to remove the extra “data” field.

I prefer to use JSON action helper to post data – like this:

// in controller
$this->_helper->json($dataToSend);

It will remove layout, disable view rendering and send proper headers.

Edit: You can also assign a variable to the view that has the key you desire – eg:

$this->view->reviews = $data;

It will remove the “data” from JSON you don’t want…
