CodeIgniter and form data

[maxxd]

Hi y'all. So I'm currently working a project in CodeIgniter and I can't get the frigging thing to pass data from a form. At all.

My autoload.php:

$autoload['helper'] = [
  'text',
  'form',
  'url',
];

Here's the view code:

<header>
	<div>
		<?php
			print form_open('/location/change', ['id'=>'location']);
			print form_label('Location', 'locations');
			print form_dropdown('locations', $locations, (!empty($_SESSION['location'])) ? $_SESSION['location'] : '');
			print form_submit('change_location', 'Change');
			print form_close();
		?>
	</div>
</header>

The route:

$route['location/change']['post'] = 'location/change';

And the controller code:

class Location extends CI_Controller{
   public function change(){

    $this->output->enable_profiler(true);

    $vars = $this->input->post();

    print("<pre>".var_export($_POST, true)."</pre>");
    print("<pre>".var_export($vars, true)."</pre>");
  }
}

The output:

array (
)

array (
)

WTF? This is quite literally the simplest thing to do - I just want to pass data... Any ideas why it's not working?

Confirm that the <form> is method=POST, and that your browser is POSTing data to the script (using its developer console). And that there isn't somehow a redirect happening.

I still don't know what the issue was - another form on the same page worked fine. I ended up refactoring to use text links instead of a drop-down and got it working. Thanks for the help!
