Hello,

I obtained this code for a php form including a Captcha that I have modified.  My question is, how do I make a field "not required", but if filled out, the entry will also be sent with the form?  I'm planning to add fields for fax, address, etc that won't be necessary, but helpful if entered.  Thank you.

 

Here is my code:

 

<?php
 
if(isset($_POST['submitted'])) {
 
require_once('captcha/recaptchalib.php');
 
$privatekey = "6Ldke-wSAAAAAPrYCfs4gR28Y10hEttom0ax-nKD";
 
$resp = recaptcha_check_answer ($privatekey,
$_SERVER["REMOTE_ADDR"],
$_POST["recaptcha_challenge_field"],
$_POST["recaptcha_response_field"]);
 
 
if(trim($_POST['checking']) !== '') {
$blindError = true;
} else {
 
$authorName = (filter_var($_POST['formAuthor'], FILTER_SANITIZE_STRING));
if ($authorName == ""){
$authorError = true;
$hasError = true;
}else{
$formAuthor = $authorName;
};
 
 
$authorEmail = (filter_var($_POST['formEmail'], FILTER_SANITIZE_EMAIL));
if (!(filter_var($authorEmail, FILTER_VALIDATE_EMAIL))){
$emailError = true;
$hasError = true;
} else{
$formEmail = $authorEmail;
};
 
$msgSubject = (filter_var($_POST['formSubject'], FILTER_SANITIZE_STRING));
if ($msgSubject == ""){
$subjectError = true;
$hasError = true;
}else{
$formSubject = $msgSubject;
};
 
//Check to make sure content has been entered
$msgContent = (filter_var($_POST['formContent'], FILTER_SANITIZE_STRING));
if ($msgContent == ""){
$commentError = true;
$hasError = true;
}else{
$formContent = $msgContent;
};
 
if (($resp->is_valid) && (!isset($hasError))) {
$emailTo = 'kcelsi@littlechisel.com'; // here you must enter the email address you want the email sent to
$subject = 'Marketing Inquiry From: ' . $formAuthor . ' | ' . $formSubject; // This is how the subject of the email will look like
$body = "Email: $formEmail \n\nContent: $formContent  \n\n$formAuthor"; // This is the body of the email
$headers = 'From: <'.$formEmail.'>' . "\r\n" . 'Reply-To: ' . $formEmail . "\r\n" . 'Return-Path: ' . $formEmail; // Email headers
 
mail($emailTo, $subject, $body, $headers);
 
$emailSent = true;
}
 
if (!($resp->is_valid)){
$captchaErrorMsg = true;
}
}
} ?>
 
<?php // if the page the variable "email sent" is set to true show confirmation instead of the form ?>
<?php if(isset($emailSent) && $emailSent == true) { ?>
        <style type="text/css">

Well it seems that your if statements all over the place.

 

Simple store the POST variable $field = $_POST['field_name']

 

As long as your not checking using a if statement like the code you have here:

$msgSubject = (filter_var($_POST['formSubject'], FILTER_SANITIZE_STRING));
if ($msgSubject == ""){
$subjectError = true;
$hasError = true;
}else{
$formSubject = $msgSubject;
};

Sorry, I have since scrapped this code.  I found it from a website tutorial that was outdated and too complicated.  I've found an amazing php form tutorial here: http://www.dreamweavertutorial.co.uk/dreamweaver/video/contact-form-php-validation.htm an I'm using that as my base form now.

 

Thanks for your input.
