How to clear POST data after processing?? - El Forum - 02-19-2010

Each time i reload the page it keeps sending the data into the db. So how can i clear the $_POST???
Code:
$res = $this->form_model->insert_data();
if($res == 1) {
$data['successmsg'] = $this->load->view('forms/thank_you','',true);
$this->load->view($data['showContent']['content_tmpl'], $data);
$_POST[] = '';//didn't work
//return false;

What I sometimes do is redirect the user to the returned page after doing what is suppose to be posted. But I am sure there is a better solution. Interested in knowing what.

Code:
$_POST[] = '';This wouldn't clear any array, it just appends a blank string to the end of it.
Code:
unset($_POST); unset($_REQUEST);Should work... mikelbring's reply works just as well too.

Hes worried about someone refreshing and being able to resubmit the post. I do not think unsetting them will work, but I haven't ever tried it either.

Ah, then yes, you would have to redirect.

Problem I see is thats creating a 301 redirect overhead. Maybe there is some http-header magic you can do.

Doing a redirect is pretty standard actually. However, you could also do a duplicate record query before committing the insert. There is no state in HTTP, you can't just clear POST.
