I have searched for this with many questions but no answers for me. I'm a newbie and I'm trying to setup a simple contact form (no database or anything). I found some code online and I'm trying to get it to work. I added code for reCAPTCHA also. I just need it to validate and send an email (to myself right now). After submit, it just reloads the page. What am I missing?
<?php
if(isset($_POST['submit'])){
$url = 'https://www.google.com/recaptcha/api/siteverify';
$privatekey = "6LcM_wkUAAAAAJO-U04kp40oshoZH0gpGTjJxeox";
$response = file_get_contents($url."?secret=".$privatekey."&response=".$_POST['g-recaptcha-response']."&remoteip=".$_SERVER['REMOTE_ADDR']);
$data = json_decode($response);
If(isset($data->success) AND $data->success==true){
//// True - What happens when user is verified.
/* Set e-mail recipient */
$email = "myemailaddress80@domain.com";
/* Check all form inputs using check_input function */
$name = check_input($_POST['name'], "Enter your name");
$phone = check_input($_POST['phone'], "Enter your phone number");
$email = check_input($_POST['email'], "Enter your email");
$message = check_input($_POST['message'], "Write a brief message...");
/* If e-mail is not valid show error message */
if (!preg_match("/([\w\-]+\@[\w\-]+\.[\w\-]+)/", $email))
{
show_error("E-mail address not valid");
}
/* Let's prepare the message for the e-mail */
$message = "Hello!
Your contact form has been submitted by:
Name: $name
Phone: $phone
E-mail: $email
Message:
$message
End of message
";
/* Send the message using mail() function */
mail($name, $phone, $email, $message);
/* Redirect visitor to the thank you page */
header('Location: thankyou.php');
exit();
/* Functions we used */
function check_input($data, $problem='')
{
$data = trim($data);
$data = stripslashes($data);
$data = htmlspecialchars($data);
if ($problem && strlen($data) == 0)
{
show_error($problem);
}
return $data;
}
function show_error($myError)
{
?>
<html>
<body>
<b>Please correct the following error:</b><br />
<?php echo $myError; ?>
</body>
</html>
<?php
exit();
}

header('location: contact.php?CaptchaPass=True');
}else{
header('location: contact.php?CaptchaFail=True');
}
}
?>
Then there is a little bit of code for reCAPTCHA
<?php if(isset($_GET['CaptchaPass'])){ ?>
<div> Message Sent</div>
<?php if(isset($_GET['CaptchaFail'])){ ?>
<div> Captcha Failed. Please try again.</div>
<?php }
}
?>
Here is the form itself:
<form action="contact.php" method="post">
<p><b>Name:<br>
</b>
<input name="name" type="text" required id="name" tabindex="1" value="" size="50" maxlength="50" />
<br />
Phone:<br>
<input name="phone" type="text" id="phone" tabindex="2" value="" size="50" maxlength="50" /><br />
<b>E-mail:</b><br>
<input name="email" type="text" tabindex="3" value="" size="50" maxlength="25" /><br />
<br>
<b>Message:</b><br />
<textarea name="message" cols="60" rows="10" maxlength="150" tabindex="4"></textarea><br>
<br>
<div class="g-recaptcha" data-sitekey="6LcM_wkUAAAAALpmzA-yLgvqo1xLoBRnfuZXWMf_"></div>
<br>
<p><input type="submit" value="Submit"></p>
</form>
