How to pass javascript function variable into php

[Jian0203]

Can anyone please teach me how do I get the 'count' from click.php and pass into the '$clicked' of clickcount.php ?

Thank you so much for helping ^.^

cllick.php

PHP Code:

<script type="text/javascript">

    var count = 0;
    function countClicks() {
    count = count + 1;
    document.getElementById("clicks").innerHTML = count;
    }
    </script> 


clickcheck.php

PHP Code:

<?php

$click = '?????'; // I don't know how should i define this
    if(!isset($clicked) || empty($clicked)) {
                die("No click is counted.");
                header = ('login3.php');
    
                } else if ($clicked > $content || $clicked < $content){
                    die("Click count(s) is not correct!");
                    header = ('login.php)';
                } else {
                 die("Login success.");
                 header = ('welcome.php');
                    }
    ?>

if your submitting a form you could load the javascript value in an input field.

The only way for JavaScript, client-side, to interact with PHP, server-side, is through Ajax.

There may be other, newer ways that I have not heard of, but Ajax would be my first go-to
