Hi, Does someone have a quick example on how to prevent multiple submits from a form? Say, a 30 sec delay until the same person can submit the

same form again?

Thanks, Chris

This might not work in your case, but what I have often done is this: <snip> Seems awfully complicated. Could alternatively be done using a smidgeon of JavaScript. <SCRIPT TYPE="text/javscript"> <!-- var somevar = 0; function disablebutton(){ if(somevar == 0){ somevar = 1; return true; }else{ return false; } } // --> </SCRIPT> And add this attribute to your submit button: ONCLICK="return disablebutton()" Untested, maybe errors. --

True - but the database approach will work regardless of browser javascript support (or, for that matter, whether the browser supports cookies, or doesn't handle no-cache headers correctly, if you're trying to use either of those approaches). -steve +--- "They've got a cherry pie there, that'll kill ya" ------------------+
