music_fan01 Posted September 11, 2011 Share Posted September 11, 2011 I am really new to using php validation, I think I may be on to what I am looking for but not very sure. I am trying to validate my form fields just incase someone forgets (name, subject, message, and email). Here is what I have so far. I was looking at an example on how to validate a phone number. <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>Contact</title> <link href="style.css" rel="stylesheet" type="text/css" /> </head> <body> <?php $first_name=$_POST['name']; $email_address=$_POST['email']; $subject=$_POST['subject']; $message=$_POST['text']; if(isset($_GET['submit'])) { if(preg_match("/^\(([ $_GET['email']) != ) { echo "The email field was invalid<BR>"; } else if(isset($_GET['submit'])) { if(preg_match("/^\(([ $_GET['name']) != "") { echo "The name field was invalid<BR>"; } else if(isset($_GET['submit'])) { if(preg_match("/^\(([ $_GET['subject']) != "") { echo "The subject field was invalid<BR>"; } else { mail("myemailaddress@gmail.com","Subject: $subject", $message, "From: $first_name <$email_address>"); echo "Thank you for using our mail form.<br/>"; echo "Your email has been sent."; } ?> </body> </html> Quote Link to comment Share on other sites More sharing options...
music_fan01 Posted September 11, 2011 Author Share Posted September 11, 2011 I found this is another example, this is something similar that I would like to add to my php. return preg_match("/^[_a-z0-9-]+(\.[_a-z0-9-]+)*@[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,3})$/", $email); Quote Link to comment Share on other sites More sharing options...
music_fan01 Posted September 11, 2011 Author Share Posted September 11, 2011 This is what I gathered from a few examples that I found, but when I run it, no error messages show up. <?php $first_name=$_POST['name']; $email_address=$_POST['email']; $subject=$_POST['subject']; $message=$_POST['text']; //Determine if the sumbit button has been clicked. If so, begin validating form data. if ($_POST['submit'] == "Submit") { //Determine if a Name was entered $valid_form = true; if ($_POST['name'] == "") { echo "Enter your name"; $valid_form = false; } else { $first_name = $_POST['email']; } if ($_POST['email'] == "") { echo "Enter a valid email address"; $valid_form = false; } else { $email_address = $_POST['email']; } if ($_POST['subject'] == "") { echo "Enter a subject"; $valid_form = false; } else { $subject = $_POST['subject']; } if ($_POST['text'] == "") { echo "Enter a message"; $valid_form = false; } elseif (strlen($_POST['text']) < 4) { echo "Enter a message"; $valid_form = false; } else { $message = $_POST['text']; } //if all form fields were submitted properly, begin processing if($valid_form == true) { mail("myemailaddress@gmail.com","Subject: $subject", $message, "From: $first_name <$email_address>"); echo "Thank you for using our mail form.<br/>"; echo "Your email has been sent."; } } ?> Quote Link to comment Share on other sites More sharing options...
