Re: Why the data in HTML form lost when the user press back button?

this is a client side issue, not a server side (php) issue. when a page is called, php is loaded, everything is worked out and php echo's the data requested, then php closes. this is the key, php closes. why should it keep running, its done its job. when the user goes to a new page, php is again called. if the user hits the back button is clicked the previous page is re-loaded, but here is where the browser faults, the page is re-loaded but the client does not re-send the data. it is in no way php's fault that a clients browser does not re-send the data. IE will at least warn you that you will have to click yes to have the data re-sent. netscape/opera will not, they just wont send the data. what you can do to fix/patch this is to use method='get' vs method='post' because the previous page will now contain all the data in the url, the data will be re-sent. of course you now have alot of GET problems, like no spaces in your variable values, etc etc. you know all about those though. I often here "php is ding this wrong, why does php do this, why is php pissing me off" haha. just think of this. "php is good, if what you are experiencing is bad, its your fault or your browsers, not php's, blame the browser" haha j/k -- Chris Lee lee@mediawaveonline.com "Carfield Yim" <carfield@programmer.net> wrote in message news:3ABB2380.2676D5D1@programmer.net...
