Preventing Page refreshing

[LOUDMOUTH]

I have a site that has some links on it to do an action. These actions give the players money and exp. After you click the link to do one of these actions, you can simply just press F5 to repeat the same action over and over. I would like to make it so when players press F5 or Click on Reload they will get a message that says "Refreshing not allowed."

 

Like this.

 

Can anyone help me out.  My site is PHP but I have heard this is not possible unless I use Java.  Looking for some help!

 

Thanks in advance!

Hi

 

From what im aware this is not possible.

Best bet is to include some php code which checks to see if the user has already performed the action.

Could use session ids possibly?

I suppose you on every page could do this:

$_SESSION['last_request'] = $_SERVER['REQUEST_URI'];

 

And then on the page you don't want refreshes on:

if ($_SESSION['last_request'] == $_SERVER['REQUEST_URI']) {
echo 'Refreshing is not allowed.';
}

 

You'll want to update the last_request at the end of script execution though.

How would I go about updating the last part of the script with the last_update part?

Uh... just place that line somewhere along the end.
