Question

I have the following controller file:

<?php
class Test extends CI_Controller 
{
    function __construct()
    {
        parent::__construct();  
    }

    function index()
    {   
        print_r($_POST);
        $view_params = array();

        $this->load->view('test', $view_params);
    }
}
?>

with a view file of:

<form action="/test" method="post">
    <input type="text" name="test" />
    <input type="submit" />
</form>

<ul id="account">
    <li class="separator url"><label>Domain Address (URL)</label><input maxlength="22" type="text" name="sub_url" />
    <small class="subtext">This is the link people use to find your site. You can change this at any time.</small>
</li>
</ul>
<img class="green_arrow" src="assets/images/green_arrow.png" />

When I hit the submit button, no post data is being spit out, but when I do a page refresh, it says data has been posted and will resend it.

Also, I think that html is just a snippet, but please understand that I am trying to reduce code and therefore reduce the number of problem areas. The reason where there is so much garbage after that is because if I remove that the view file ceases to work, but that’s another question.

Answer 1

CodeIgniter empties $_POST, $_GET etc. for security purposes. Use the Input class instead.

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

or

$some_data = $this->input->post('some_data');
