block auto-refresh

[jasek78]

I'm trying to block auto-refreshing on a webpage. Either by a browser plugin (FF), The Opera browser's 'auto-reload' feature or by clicking the refresh button. Does anyone know of a way i can do this?

thanks

Jason

Not with PHP, Since it runs on the server, it has no control over browser functions.

You would need Javascript or some other Client Side script to disable it.

Although many people may find the inability to refresh annoying. Maybe you should rethink your script, and whgy you need to block the refresh button.

Is there a chunk of header info or something that i can read and determine if the page was refreshed via the browser?

a header variable that i can access via php?

You can have your script check for something such as a session variable, you set

If the variable is set, that means the script has already been run, and more than likely the browser has been refreshed. If that is the case, then you do not proceed with the rest of the script, and either redirect somewhere, or issue a message.

If however the session variable is not present, that means the script is being run for the first time, hence you proceed with it.
