HTMLHelp Forums _ Server-side Scripting _ Validator for form
Posted by: lamboman Apr 28 2017, 01:51 PM
Forms are not my strong point.Below I have the form and it works fine. I also have a validator script below that works as it is but I want to add the comment part to it and whatever I do it seems to not work.
<form action="send_form_email.php" method="post">
<div class="one_third first">
<label for="first_name">Name <span>*</span></label>
<input type="text" name="first_name" id="first_name" value="" size="22" required>
</div>
<div class="one_third">
<label for="email">Mail <span>*</span></label>
<input type="email" name="email" id="email" value="" size="22" required>
</div>
<div class="block clear">
<label for="comment">Your Comment</label>
<textarea name="comment" id="comment" cols="25" rows="10"></textarea>
</div>
<div>
<input type="submit" name="submit" value="Submit Form">
<input type="reset" name="reset" value="Reset Form">
</div>
</form>
<?php
if(isset($_POST['email'])) {
// EDIT THE 2 LINES BELOW AS REQUIRED
$email_to = "My email";
$email_subject = "Inquiry from site";
function died($error) {
// your error code can go here
echo "We are very sorry, but there were error(s) found with the form you submitted. ";
echo "These errors appear below.<br /><br />";
echo $error."<br /><br />";
echo "Please go back and fix these errors.<br /><br />";
die();
}
// validation expected data exists
if(!isset($_POST['first_name']) ||
!isset($_POST['email'])) {
died('We are sorry, but there appears to be a problem with the form you submitted.');
}
$first_name = $_POST['first_name']; // required
$email_from = $_POST['email']; // required
$error_message = "";
$email_exp = '/^[A-Za-z0-9._%-]+@[A-Za-z0-9.-]+\.[A-Za-z]{2,4}$/';
if(!preg_match($email_exp,$email_from)) {
$error_message .= 'The Email Address you entered does not appear to be valid.<br />';
}
$string_exp = "/^[A-Za-z .'-]+$/";
if(!preg_match($string_exp,$first_name)) {
$error_message .= 'The First Name you entered does not appear to be valid.<br />';
}
if(strlen($error_message) > 0) {
died($error_message);
}
$email_message = "Form details below.\n\n";
function clean_string($string) {
$bad = array("content-type","bcc:","to:","cc:","href");
return str_replace($bad,"",$string);
}
$email_message .= "First Name: ".clean_string($first_name)."\n";
$email_message .= "Email: ".clean_string($email_from)."\n";
// create email headers
$headers = 'From: '.$email_from."\r\n".
'Reply-To: '.$email_from."\r\n" .
'X-Mailer: PHP/' . phpversion();
@mail($email_to, $email_subject, $email_message, $headers);
?>

Try adding this:
$comment = strip_tags($comment);
$email_message .= clean_string($comment)."\n";
after this line:
Note that this will only perform basic sanitation by removing HTML tags, it doesn't limit the min- or maxlength of the message.
BTW, why do you use so much whitespace in your code example? I'm curious because I've seen it in other forum posts too --is it some text editor that causes it?

Cant thank you enough. Works just as I hoped. Not sure about the white spaces. I believe I copied this script from somewhere so i am guessing it was like that originally. Thanks again.
