validate php contact form with checkbox
I am trying to add another validation to a contact form. I need a checkbox at the bottom of the form which the user check before they can submit the form.
This is what i have so far, which validates the form. I would like to know how to add a checkbox so the form is only submitted if the box is checked

When validating the forms I code, I just use the Recaptcha. Is this an option for you? If it is then you need the site to be live so you have access to the domain name of the site.
To begin this go to: https://www.google.com/recaptcha/intro/v3beta.html
Get a SITEKEY & SECERTKEY - they have step by step (very simple) on how to access these two keys.
Once you have them only a small snippet of code in the head tags like so:
<head>
<script src='https://www.google.com/recaptcha/api.js'></script>
</head>
After, you just have to add the code into your form tags like so:
<form>
<!-- put this wherever you want it in the form - usually at the bottom -->
<div class="g-recaptcha" data-sitekey="<!-- Site Key HERE -->"></div>
</form>
And then finally just authorise it in your PHP code that handles the form data, for example:
$captcha = $_POST["g-recaptcha-response"]; // Declare variable
if(isset($_POST['g-recaptcha-response'])){
$captcha=$_POST['g-recaptcha-response'];
}
if(!$captcha){
header("Location: <!-- Error HTML page OR echo and error statement -->");
exit;
}
$secretKey = "<!-- SECRET KEY HERE -->";
$ip = $_SERVER['REMOTE_ADDR'];
$response = file_get_contents("https://www.google.com/recaptcha/api/siteverify?secret=".$secretKey."&response=".$captcha."&remoteip=".$ip);
$responseKeys = json_decode($response, true);
if(intval($responseKeys["success"]) !== 1) {
echo '<h2>Spam Detected</h2>';
}
else {
header("Location: <!-- Thank you HTML page OR echo and thanks statement -->");
}
You'll see I've commented where the site & secret key go.
