note 59661 added to function.mail

A way to keep out spamers if in your form or script tell about From e-mail, and put it in the Header is (if the variable name is email): $emiliu = $_REQUEST['email']; if ( preg_match ( "/^[-\w.]+@([A-z0-9][-A-z0-9]+\.)+[A-z]{2,4}$/", $emiliu) ) { OK ... bla... bla.... bla $mailHead = "From: " . $_REQUEST['email']; mail($mailTO, $mailSbj, $mailBodyC . $mailBody, $mailHead); } else { BAD HEADER } ---- Manual Page -- http://www.php.net/manual/en/function.mail.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+59661 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+59661&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+59661&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+59661&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+59661&report=yes&reason=useless Delete: non-english -- http://master.php.net/manage/user-notes.php?action=delete+59661&report=yes&reason=non-english Delete: already in docs -- http://master.php.net/manage/user-notes.php?action=delete+59661&report=yes&reason=already+in+docs Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+59661&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+59661&report=yes Search -- http://master.php.net/manage/user-notes.php
