Input field with AJAX

[Pauldro]

I'm looking to do a specific type of module. I want to use the field-typemulti fieldtype. So what I want to accomplish is
the first field part stores a category (movies, books, etc.). The Second input field would need to be an AJAX lookup that would let me choose the ID of that book so I can take it and save it into my post. So let's just say the thing I'm pulling from is IMDB, I'll choose the movie category, then On the lookup get a list of movies based on a search. IF you can point me and help me out with this i'd greatly appreciate it!

I would say a ProcessModule for the AJAX request. That module should extend Process and Make sure the config array contains 'permission' => 'page-edit'

No need for a extra Process page. Just send a ajax POST/GET request with a special key you recognize in your module's init(), do the work and send back an result.

Hi @Soma. Could you please elaborate on how to do this? I don't quite follow what is being sent where . Thanks..

Something along the way

public function init(){
	if($this->config->ajax && $this->input->InputfieldMyAjaxBomb){
		// handle your ajax request
		header('Content-Type: application/json');
		echo "{'yo':'yo'}";
		exit;
	}
}

.. in your Inputfield init(). Then you can make a post or get AJAX request to any backend or public url the current url containing the key InputfieldMyAjaxBomb=1.

Edit: Originally I didn't really mean that there's "no need". Well, of course a hidden admin ProcessPage bundled with your module is also good and honestly maybe even the more correct way. But It's easy to implement and test things out too.

Thanks Soma. I have been doing it the 'hidden-admin-page-way'...as you suggested way back in this thread . Good to know there's other ways too.
