Help with User Registration Function?

[eluser]Buso[/eluser]
A blank page could also mean that there has been an error, but error_reporting level is lower than the error level. Inside index.php, try changing error_reporting(0) to error_reporting(E_ALL) if that's the case. You can turn it back to 0 when your game is at the production stage.

Oh and try moving all the code you can to a model. Controllers should be as tiny as possible

The workflow for registration could be something like this:

Code:

function register() {
  
  // if the form hasn't been submitted yet, or there has been a validation error:
  if( ! $this->input->post('submit') OR validation_errors()) {
    $this->load->view('register_form');
    return;
  }

  // set validation rules, etc

  // try to pass the validation. On failure, show the form again.
  if( ! $this->form_validation->run()) {
    $this->register();
    return;
  }

  // otherwise, process the form:
  if( ! $this->user_model->register($_POST)) {
    // another kind of error happened
    $this->register();
    return;
  }

  // everything is fine, the user has been registered.
  redirect('success');

}
