Convert javascript variable into php and send it using session

Question

I want to send article id using session, Source page contains many links to open one webpage but id is there in ID attribute of a href. like

<br/>
< a id="13" class="openpage" href="test.html">open test form< /a><br />

I have used javascript to pass the variable

$(".openpage").on('click', function() {
    var artid = $(this).attr("id");
    <?php $_SESSION['artid'] = "<script>document.write(artid)</script>"?>
    });

var artid is having the correct value before loading the new page and $_SESSION['artid'] is not getting the value of artid.

You'll have to update your index file and the test.html becomes test.php

jQuery part of the code takes the value of your ID attribute on the link Stores it in a cookie.

In your test.php The value of the COOKIE is assigned to your SESSION and the COOKIE is cleared using the in-built php set_cookie() function to set the cookie with an empty value (For security reasons);

The cookie expires in 1 minute. you can update it if you like.

-

//index.php file

<a id="13" class="openpage" href="test.php" >open test form</a>

<!-- JS HERE ---> 

<script src="http://code.jquery.com/jquery-3.2.1.min.js"></script>
<script type="text/javascript">
    $(document).ready(function(){

 function setCookie(key, value) {
            var expires = new Date();
            expires.setTime(expires.getTime() + (60 * 1000));
            document.cookie = key + '=' + value + ';expires=' + expires.toUTCString();

}

  $(".openpage").on('click', function() {
      var artid = $('.openpage').attr("id");
        setCookie('cookie_session', artid);
});

});
</script>

//test.php file

 <?php
      if(isset($_COOKIE['cookie_session'])):
      $_SESSION['artid'] =  $_COOKIE['cookie_session'];
      setcookie("cookie_session", '');
      echo $_SESSION['artid'];
      endif;
   ?>

Here's a screenshot of the COOKIE in the browser's Dev tool > Application > Cookies

As you can see the COOKIE is no more in your browser and the SESSION now holds the data.

Hope this helps :)

Thanks for reply, I am not getting the value in test.php file while checking the $_POST['yourId'] in test.php file it is saying Undefined index: yourId — Azhar A, Jul 27 '17 at 06:46
