Exiting Controller - El Forum - 09-02-2008

I have created a form and my controller script validates it and builds an error message in the variable $errorMessage. I then test if $errorMessage is not NULL, I display the form again with an error box. I then want to exit the script:

Code:
// header displayed earlier in code

if ($errorMessage != NULL) {

    $row->al_error_message = $this->error->error_box($errorMessage);

    $this->load->view('newsletter_form', $row);

    $this->load->view('footer', $settings);

    exit;

}

However, nothing displays. Is there a way to output what is already passed to output before I exit?

Thanks

Your code does not seems any problem. are you sure your program enter into the if condition. if yes then check this function

Code:
$this->error->error_box($errorMessage);

. and also debug your code......

Since a while exiting in controllers might not show any output (due to partial view support). The best (and also cleanest way) is:

Code:
// header displayed earlier in code

if ($errorMessage != NULL) {

    $row->al_error_message = $this->error->error_box($errorMessage);

    $this->load->view('newsletter_form', $row);

    $this->load->view('footer', $settings);

    return;

}
