Here's a quickie for validating email in javascript and php (note: i added lines to make it more readable than copy-and-pastable) javascript: var email_exp = /^(([^<>()[\]\\.,;:\s@\"]+ (\.[^<>()[\]\\.,;:\s@\"]+)*)|(\".+\")) @((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\])| (([a-zA-Z\-0-9]+\.)+[a-zA-Z]{2,}))$/; php: if (eregi("^[_a-z0-9-] +(\.[_a-z0-9-]+)*@[a-z0-9-]+ (\.[a-z0-9-]+)*(\.[a-z]{2,3})$", $email)) { *DO_SOMETHING* }
