How can you use a JavaScript variable in the PHP isset function?
You can't actually do that. There is no direct way to make JavaScript code talk to PHP code, as the two languages are interpreted in different locations. The PHP is interpreted by the server, and the JavaScript is interpreted by the client. This means it's easy enough to transfer data from PHP to JavaScript (by generating the JavaScript with the PHP), but not the other way around. If you're simply looking for a way to see if a JavaScript variable is set (from within the JavaScript itself), that can be done with a line like this one: if(myVariable !== undefined){ /* do stuff */} If you actually want to handle it on the PHP side, one way to do so would be to use additional PHP code when that happens. For example: <?php $jsVars = array(); ?> <script type="text/javascript"> var foo = 'bar'; <?php $jsVars['foo'] = 'bar';?> var yub = 'nub'; <?php $jsVars['yub'] = 'nub';?> </script> ... You can then check to see whether a certain variable has been set by seeing if it's in that array: <?php function jsIsset($varname){ global $jsVars; return array_key_exists($varname, $jsVars); } ?> This however, only works when the JavaScript is generated, not when it's interpreted by the client system. For example, imagine you have a variable that is defined by a JavaScript function that is called from an onclick event. By the time that event happens, the page has already been served and the PHP is done executing. If you want the JavaScript to tell the PHP that a variable is defined, you would need to do it through an AJAX request, which I believe is beyond the scope of this question.
