Clear Log On Exit

[Bob Norris]

Hi,

Anybody have an idea how I can clear a txt log on page exit using PHP? They reside in the same folder and the txt file hascorrect permissions. Something like this: function deletelog()

What do you meen by page exit?

When the page closes. After someone leaves. Im trying to clear a chat log after they go using php

that has to be javascript, or javascript accessing a php script. php runs before the page loads.

unless the user is logged in with a login system..then when they exit and the session is ended or use your logout function..then the log could be told to clear..

Not quite that simply but yes, its possible.

You need to do two things.  First, setup a javascript function to be called when the page is left.  I think this is called onblur or something like that, you can find the exact function name using google.  The other thing you need is to have the a PHP script to clear the log.  Next, have the javascript function call out to the PHP script using an Ajax http request.  You might have to customize the javascript for different browsers, but I know it can work.
