obsidian Posted December 21, 2006 Share Posted December 21, 2006 I would personally recommend you do your processing first, and then display the error [b]above[/b] the form to assure that the user will see the error message. Try something like this:[code]<?phpif (isset($_POST['submit'])) { $error = array(); if (!preg_match('|^[a-z]+$|i', $_POST['text1'])) $error[] = "First textfield may only contain letters"; if (!preg_match('|^[0-9]+$|i', $_POST['text2'])) $error[] = "Second textfield may only contain numbers"; if (!preg_match('|^[A-Z0-9._%-]+@[A-Z0-9.-]+\.[A-Z]{2,4}$|i', $_POST['text3'])) $error[] = "Third textfield must contain a valid email address"; if (count($error) > 0) { $msg = "<p class=\"error\">The following errors occurred:<br />\n" . implode('<br />\n', $error) . "</p>\n"; } else { // Success! }}// Show your message if there is oneecho isset($msg) ? $msg : '';// Now, display your form?>[/code]Also, make note that your regular expressions did not have the terminating string '$' that is needed to assure that they contain [b]only[/b] those characters. As you have them currently checking, they only have to [b]start[/b] with one or more of the specified characters.Hope this helps.

NickG21 Posted December 21, 2006 Author Share Posted December 21, 2006 obsidian, i agree that works much better and is much more manageable, however I receive this error after trying to put that code into mineWarning: implode(): Bad arguments. in .../testing1.php on line 16[code]<?phpif (isset($_POST['submit'])) {$email = $_POST['email'];$name = $_POST['text1'];$number = $_POST['text2'];$error = array();// check e-mail address// display success or failure messageif (!preg_match("/^([a-zA-Z])+/",$_POST['text1'])) $error[] = "Your Name May Only Contain Letters";if (!preg_match("/^([0-9])+/",$_POST['text2'])) $error[] = "Invalid ZipCode, Please Re-Enter";if (!preg_match("/^([a-zA-Z0-9])+@([a-zA-Z0-9_-])+(\.[a-zA-Z0-9_-]+)+/", $_POST['email'])) $error = "Invalid E-Mail Address";if (count($error)>0){$msg = "<p class=\"errpr\">The Following Errors Were Found:<br/>\n". implode('<br />\n', $error).

obsidian Posted December 21, 2006 Share Posted December 21, 2006 I believe it should be:[code]<?phpif (isset($_POST['submit'])) { $email = $_POST['email']; $name = $_POST['text1']; $number = $_POST['text2']; $error = array(); // check e-mail address // display success or failure message if (!preg_match("/^([a-zA-Z])+/",$name)) $error[] = "Your Name May Only Contain Letters"; if (!preg_match("/^([0-9])+/",$number)) $error[] = "Invalid ZipCode, Please Re-Enter"; if (!preg_match("/^([a-zA-Z0-9])+@([a-zA-Z0-9_-])+(\.[a-zA-Z0-9_-]+)+/", $email)) $error[] = "Invalid E-Mail Address"; if (count($error)>0) { $msg = "<p class=\"errpr\">The Following Errors Were Found:<br/>\n". implode('<br />\n', $error). "</p>\n"; } else { $msg = "<p>Thank You, Your Information Has Been Accepted</p>"; }}echo isset($msg) ? $msg : '';?>[/code] Quote Link to comment https://forums.phpfreaks.com/topic/31501-solved-simple-form-validation/#findComment-145984 Share on other sites More sharing options...
