PHP Contact Form with Verification Image

Contact forms are a great way to enable visitors to your site to contact you. But to prevent it abuse by spammer, the form with the verification image will help. For this example, you need to create 3 files index.php (form interface) and mailer.php (send mail script) , verificationimage.php (to check whether is valid visitor)

(a) Create a form in index.php that retrieve the information Subject, Email Account, Verification and Message

<form action="mailer.php" method="post" name="form1" id="form1" onsubmit="MM_validateForm('from','','RisEmail','su bject','','R','verif_box','','R','message','','R') ;return document.MM_returnValue">
Your e-mail:<br />
<input name="from" type="text" id="from" value="<?php echo $_GET['from'];?>"/>
<br />
Subject:<br />
<input name="subject" type="text" id="subject" value="<?php echo $_GET['subject'];?>"/>
<br />
Type verification image:<br />
<input name="verif_box" type="text" id="verif_box" />
<img src="verificationimage.php?<?php echo rand(0,9999);?>" alt="verification image, type it in the box" width="50" height="24" align="absbottom" /><br />
<br />
<?php if(isset($_GET['wrong_code'])){?>
<div style="border:1px solid #990000; background-color:#D70000; color:#FFFFFF; padding:4px; padding-left:6px;width:295px;">Wrong verification code</div>
<br />
<?php ;}?>
Message:<br />
<input name="message" cols="60" rows="5" id="message" value="<?php echo $_GET['message'];?>" />
<br />
<input name="Submit" type="submit" value="Send Message"/>

(b) Then create a send_contact.php with the code as below.

// Contact subject
$subject =$_POST['subject'];
// Details
// Mail of sender
// From
$header="from: $name <$mail_from>";
// Enter your email address
$to ='test@test.com';
// Check, if message sent to your email
// display message "We've received your information"
echo "We've received your contact information";
else {
echo "ERROR";
