I have tried a few ways, and it seems I haven't found a way to output a JSON string from a Controller extended from Controller_Template. I'm trying to make a form which is AJAX based, but if JavaScript isn't working it degrades to the form page.

You can disable the template auto rendering by setting the value of $auto_render to false in your action function. Example: <?php class Controller_Test extends \Controller_Template { public function action_form() { // ... if($ajax_detected) {
$this->auto_render = false;
echo json_encode( /* ... */ );
} // ... }
}

Thanks Sebastien, also is it safe to echo from the controller ? or would a $this->response(); work like with the REST controller ?

Sebastien

Forget the echo, it was ugly and I did this example very fast. This is better: $this->response->body = json_encode(array('plop')); The $this->response() function is not available because your controller extends Controller_Template and this function is only provided by Controller_Rest.

I know this post is a little dated, but for anyone browsing for similar issues, you can use:

// data array containing the info you want to convert to json
$data = array(
    'field1' = 'data1',
    'field2' = 'data2'
);

$this->response->body = \Format::factory($data)->to_json();

Take a look at the Format Class Docs... http://fuelphp.com/docs/classes/format.html there are several other helpful items of interest in there.

I didn't see this mentioned, so it's worth saying. There is an "is_ajax" method within the Input class, so if($ajax_detected) might be improved as... if(Input::is_ajax) Maybe you already knew about this, but if not I wanted to give a heads up as I went through creating my own ajax checks for a few projects before I realized this method existed.
