使用AJAX / JSON将对象数组传递给PHP

I need to pass a Javascript array of objects to PHP. Found about 3 solutions on the internet, but none of them worked for me. The array looks like this (in Chrome dev console):

And my current AJAX call looks like this:

function consolidate() {
        var studentsstring = JSON.stringify(students);
        $.ajax({
             type: "POST",  
             url: "writefile.php",
             dataType: "json", 
             data: {students: students},
             success: function(data) {
                  alert(data);
             }
        });
    }

And the PHP file looks like this:

<?php
print($_POST['students']);
?>

Currently, when I hit the "consolidate" button, nothing happens. No alert is shown. Chrome dev reports no errors in the code.

Oh, I'm dumb. Too many hours of coding. The line should have been:

data: {students: studentsstring},

and now it works. Thanks all.
