Help with Contact Form Honeypot

PHP
1

I’ve set up a ‘Honeypot’ Contact Form, but still get spam.
Here is the code:

<head>
...
<style>
.zip{
visibility: collapse;
}
</style>
...
</head>

<body>
...
<form action='../submit.php' method='post' name='myform' onSubmit="return checkemail()">
<textarea name="message" value="placeholder text" input type="text" onfocus="this.style.color='#f2f2f2';
this.value='';">Contact us - Enter your message here...</textarea>

<input class="form-control" type="text" id="name" name="name" maxlength="50" placeholder="Name">
<input class="form-control" type="text" id="email" name="email" maxlength="50" placeholder="Email">

<input name="zip" type="text" id="zip" class="zip" autocomplete="false">

<input class="btn btn-action" type='submit' value="Send Message">
</form>
...
</body>

<?php
//check if form was sent
if($_POST){
$to = 'contactForm@....com';
$subject = 'ContactForm';

$name = $_POST['name'];
$email = $_POST['email'];
$message = $_POST['message'];
$headers = $name;
$message .= "\r\n\r\n" . $name;
//honey pot field
$honeypot = $_POST['zip'];
//check if the honeypot field is filled out. If not, send mail.
if( $honeypot > 1 ){
return;
}else{
mail( $to, $subject, $message, $email, $headers );
}
}
?>

I received several spam replies all similar to this (instead of legitimate email address, message and name):

Any help/suggestions on how to fix this so no (or very little) spam gets sent, will be appreciated.

this makes no sense, you do not get any real numbers by a form, just check with

var_dump($honeypot);
var_dump($honeypot > 1);

what you need is empty().

also this is not a spam protection script, this is actually a spam bot itself

stop using mail(), take a wrapper like PHPMailer or Swiftmailer.

You’re using honeypot the wrong way. The honeypot is supposed to be invisible to human eyes. Bots typically type in any text field regardless of styles or JavaScript. If you are a legitimate person, modern browsers typically have CSS and JavaScript turned on. So you wouldn’t be seeing these honeypots.

Thanks for your replies.

What do you mean by: empty()
Can you give me an example using my current script, please?

Also, regarding “the honeypot is supposed to be invisible”,
as far I can see it doesn’t appear in the Form.
So, how am I using it “the wrong way”?

I look forward to any additional help.

I was referring to the CSS. But it seems that collapse works. The next thing is what @chorn and @SamA74 was talking about. You have to make sure that the text field isn’t empty. If it isn’t empty, then a bot submtted something to it. This is where you can do extra work/
