if(!preg_match("^[_a-z0-9-]+(\.[_a-z0-9-]+)*@[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,3})$", $email)) {             echo "invalid email form please reenter<br />";} 

any suggestions. mean if wasn't new maybe figure out, xq's laziness.

thank in advanced.

your pattern needs have starting , ending delimiter (in case i've used ~), see preg_match:

preg_match("~^[_a-z0-9-]+(\.[_a-z0-9-]+)*@[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,3})$~", $email); 

the delimiter used mark beginning & ending of pattern. after ending delimiter can add modifiers such case insensitive (i):

$pattern = '~^[a-z]{3,6}$~i';
