I have the @ sign being validated, but I can't get the period to work.. Can someone help me out? Here's my code.. if ($_POST['Travel_Request_Email_Address'] != "") { if (preg_match_all("/(@)/", $_POST['Travel_Request_Email_Address'], $match) != 1) { $errorcount++; $error = $error . " " . $errorcount .") <font color=\"red\">Email Address</font> field does not contain @<br> \n"; } else if (preg_match_all("/(.)/", $_POST['Travel_Request_Email_Address'], $match) < 1) { $errorcount++; $error = $error . " " . $errorcount .") <font color=\"red\">Email Address</font> field does not contain .<br> \n"; } else { $_SESSION['Travel_Request_Email_Address'] = $_POST['Travel_Request_Email_Address']; } } else { $errorcount++; $error = $error . " " . $errorcount .") <font color=\"red\">Email Address</font> field is empty<br>\n"; } Thanks, Jake McHenry Nittany Travel MIS Coordinator http://www.nittanytravel.com -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
