<script>
    $(document).ready(function(){
        // click on button submit
        $("#submit").on('click', function(){
            // send ajax
            $.ajax({
                url: 'tier_one_submit_status.php', // url where to submit the request
                type : "POST", // type of action POST || GET
                dataType : 'json', // data type
                data : $("#form").serialize(), // post data || get data
                success : function(result) {
                    // you can see the result from the console
                    // tab of the developer tools
                    console.log(result);
                },
                error: function(xhr, resp, text) {
                    console.log(xhr, resp, text);
                }
            })
        });
    });

</script>
</body>
</html>

after click the submit button, i would like to update the data individually.

Please help.

Instead of naming the fields like "remark[]", put keys into those arrays. Like "remark[EE123]".

When you foreach on them you'll have that ID available to use.

foreach ($_POST["remark"] as $id => $remark) {
	$status = $_POST["status"][$id];

Make sure to double-check that the employee with that ID is allowed to be updated by this form - probably by using whatever criteria you had when you first showed the form.
