Form input fields validation via jQuery and PHP

Question

I want to validate my form input fields on button click in jQuery. But I don't want to use client side validation. How can I add PHP server-side validation on button click?

I am using modal box for form.

I know it is a beginner's level question, but currently I am unable to figure it out because of my low expertise.

Yes you can validate using PHP and it's not a big deal. I'll provide a simple example here to pass the form data to PHP for validation.

<?php
if( isset($_POST['submitForm']) )
{
    $userName = $_POST['userName'];
    $userAge = $_POST['userAge'];
    
    if ($userAge > 21)
    {
      echo "Hey " + userName;
    }
}
?>
<html>
<body>
<form method="POST" action=""> 
    Name: <input type="text" name="userName">
    Age: <input type="number" name="userAge">
    <input type="submit" name="submitForm" value="Validate"> 
</form>
</body>
</html>

If you wish to pass the data to another page to validate, just give the file name in action attribute, like action="Your_PHP_File.php" and validate separately. Just a tip : If you wish to redirect on success (heavily used):

header("Location: Your_URL_Here");

Anyways, this is not a better user experience. You must use client side validation using JavaScript/any JavaScript framework, and use language like PHP only to communicate with the server, such as storing the data in the database, retrieving data from the database.
