I'm new to PHP and JS and I'm currently working on a gym management web app for our project in school. I'm adding a bit of QR functionality that sees if the user is eligible to enter the gym or not by checking if the user has paid. I want to know if it is good to escape PHP code in inline JS, or would it be better to get the id via ajax and store it into a js variable?

</script> ... new QRCode(document.getElementById("qr-code"), "./functions/check_if_paid_qr.php?id=<?php echo $_SESSION["member_id"] ?>"); </script> 

I'm using qrcode.js btw.
