Re: form submission error trapping

Navid, $SCRIPT_NAME is sometimes a safer alternative than $PHP_SELF. The difference is that $PHP_SELF includes $PATH_INFO while $SCRIPT_NAME is just the name of the actual script running. http://www.php.net/manual/en/language.variables.predefined.php This becomes particularly important if you use $PATH_INFO to implement elegant (and search-engine safe) urls e.g. /search/products/myproduct rather than /search.php?category=products&key=myproduct.
