Trying to clear $_POST

[mustardman]

Typical situation that is called Post/Redirect/Get.

 

I have a custom product details page based on the WHMCS sample provisioning module.

https://github.com/WHMCS/sample-provisioning-module

 

I have a form in product details area that posts data into

function provisioningmodule_ClientArea($params)

.

 

The problem is that I cannot clear $_POST information afterwards. So when the browser is refreshed the $_POST data is resent.

 

The typical method to get around this as found on the internet is to use

header("Location: " . $_SERVER['REQUEST_URI']);

exit();

 

That should reload the browser, clear $_POST, and return me to

/clientarea.php?action=productdetails&id=xxxx

. However it takes me back to

clientarea.php?action=services

.

 

Can't figure out why. The 'REQUEST_URL is correct but WHMCS doesn't like it for some reason and goes back to clientarea.php?action=services

 

unset($_POST) and $_POST = array(); doesn't clear it because it needs to be cleared from the browser not in PHP.

I figured out how to get around it. I think WHMCS needs $_POST if you are staying on the same page because it includes the service/product ID.

 

I ended up creating a variable in $_SESSION to track when a form has been posted once so it's not posted a second time on browser refresh.

 

if ($_SESSION['submitted'] == 1 && !isset($_POST['customformdata'])) {

unset($_SESSION['submitted']);

}

..

..

if ($_SESSION['submitted' != 1]) {

//Do some stuff with $_POST custom form data

$_SESSION['submitted'] = 1;

}
