Actual behavior

PHP is not working in html and im not sure how to implement PHP code from this examples to my mail.php and connnect with bottons and form to get it working.

My mail.php:

include_once("./mail_settings.php");

$name = (isset($_POST['name'])) ? $_POST['name'] : '';

$email = (isset($_POST['email'])) ? $_POST['email'] : '';

$message = (isset($_POST['message'])) ? $_POST['message'] : '';

$phone = (isset($_POST['phone'])) ? $_POST['phone'] : '';

if ($name === '') {

die("Prosimo, izpolnite zahtevano polje."); }

if ($email === '') {

die("Izpolnite zahtevano polje!.");

} else if (!filter_var($email, FILTER_VALIDATE_EMAIL)) {

die("Email je neveljaven.");

}

if ($phone === '') {

die("Prosimo, izpolnite zahtevano polje.");

}

if ($message === '') {

die("Prosimo, izpolnite zahtevano polje.");

}

$content="From: $name \nEmail: $email \nMessage: $message \nPhone: $phone";

$recipient = "info@regresija-hipnoza.si";

$mailheader = "Sporocilo: $email \r\n";

$email_subject ='Regresija-hipnoza';

$mail->Subject = $email_subject;

$mail->Body = $content;

$mail->AltBody = $sporocilo;

$mail->SetFrom($email, $name);

$mail->AddCC($recipient, "regresija hipnoza");

$mail->send();

if (headers_sent())

echo "window.top.location='https: //www.regresija->hipnoza.si/zahvalna-stran.html';";

else

header("location: https://www.regresija-hipnoza.si/zahvalna-stran.html", true, 301 );

?>

Heney pot is just hidden input and condition to check if input has not been fulfilled. So you just need to add PHP code to <code>mail.php</code> and HTML code to your HTML file.

It is a bit different with captcha. This requires the execution of PHP code in the same file. But it is enough to convert this code into JS:

HTML

JS

<pre class="prettyprint"><code>const number1 = document.querySelector('#firstNumber');
const number2 = document.querySelector('#secondNumber');

const min = Math.ceil(1);
const max = Math.floor(300);
const num1 = Math.floor(Math.random() * (max - min)) + min;
const num2 = Math.floor(Math.random() * (max - min)) + min;
const sum = num1 + num2;

number1.innerText = num1;
number2.innerText = num2;
</code></pre>

Now you just have to check to submit that the input value is the same as the variable sum

Of course the second solution is to create a form in a php file instead of using an HTML file

Please insert min. 20 characters.

From what I understand are you trying to use PHP in an HTML file? You should do this in PHP file.

Yes I would like to add PHP code of Math capctha and Honey pot in mail.php and connect PHP with js or Ajax or somehow. Is this possible or there is some better way?
