Load the form helper in the controller:

Code:

<?
print_r($temporary_data);
if ($action == "register_success") {
    ?>
    <h2>Success!</h2>
    Congratulations, registration successful. We sent you an email with account confirmation link.
    &lt;?
} else {
    $this->load->helper('form'); // Move this to the controller
    echo form_open(base_url() . 'register');
    ?&gt;
...

Can anyone help me with it ?

Thanks.

Check that you have configured base_url() in the application/config/config.php

Use this form for base_url(). See the user guide: user_guide/helpers/url_helper.html

Code:

echo form_open( base_url('register') );

form_open() already inserts base_url(), so you'd be doing it 2x. (view the outputted source) You only include the controller/method.

It should just be form_open('register/index') if going to the index method of the register controller.

When you fill all inputs its ok, no error. Thats weird.

I don't see anywhere where you are displaying the errors, if there are any.

You should always use full open php tags, even if YOUR server is set to use short tags.

Code:

<?php

and always leave off the very last closing php tag on the page to avoid whitespace problems.

I mean when you fill whole form the 500 error won't appear.

The problem was a bad tutorial. 'callback_checkuser' had to be 'checkuser'.

Thanks for your help.
