What's the proper way to return an AJAX response within an ExpressionEngine module?

Good ole' echo "foo"; die(); seems to work but there must be a better way!

I tried the CodeIgniter approach $this->EE->output->set_output(json_encode($array));

Thanks for the help!

You can use


for the same purpose.

  • This is good for returning JSON data only it seems as I couldn't get it to return just a string via AJAX. Mar 5, 2013 at 4:38

If you are trying to return data other than JSON I ended up using the following instead. It's mostly ripped off from the same send_ajax_response function that Bhashkar was kind enough to lead me to. You should probably choose the proper Content-Type (so maybe if it was XML it would be different?).

$this->EE->config->item('send_headers') == 'y';
@header('Content-Type: text/html; charset=UTF-8');
