Passing GET value into function

[eluser]alboyd[/eluser]
I feel like an idiot but please tell me what I am doing wrong? THis is soooo frustrating!

I need to use GET for a JQUERY autocompleter. I am sending URL

base_url/controller_name/function_name?q=Al

and
function function_name()
{
$get_val = $this->input->get('q');
echo $get_val;
die();
}

I get a blank page! What's up with that?? please help thanks

Do you have query strings enabled? If so, I thought the syntax needed to be something like - http://your_site.tld/?c=controller_name&m=method&q=Al

Thanks that improves the situation - however now I get a response Disallowed Key Characters from the autocompleter

There are a few threads on jQuery and autocomplete on the forums, maybe reading through them will give some pointers in the right direction

That's awesome thanks heaps! Found the revised autocomplete code which users function params instead of GET. Much better thanks!! Now I just have to figure out why the auto-complete isn't inside my inputbox!

if you are using the JQuery autocomplete you just attach it to an id

Code:

$('#myinput').autocomplete('/url/to/autocomplete');

Thats the way I do it and the generated list appears below the input box.

If you are talking about this jQuery autocomplete:
http://www.devbridge.com/projects/autocomplete/jquery/

Then all you have to do is change the $.get() call to $.post() on line 222, and use $this->input->post('query') in CodeIgniter. If you're using a different jQuery library, then somewhere in there they likely make a $.get or $(this).get() call, and you can usually replace that with 'post' and be ok. The $.get() and $.post() functions both take the same parameters.
