Incorrect format of data sent by $.post to PHP

Question

I'm trying to send a JavaScript Object() to a PHP file in the correct format that $.POST wants. The PHP file doesn't set any $_POST[] variables so i must be sending it in an incorrect format.

JS:

$('#downloadBtn').click(function(){
    var form_data = new Object();
    form_data.filepath = $("#fileName").html();
    $.post( 
        "/UpdateDownloads.php",
        { JSON.stringify(form_data) },
        function(data) {
            alert(data);
        }
    );
});

I know that changing the sent data to "{ filepath: form_data.filepath }" will fix the problem, but this is a sloppy fix because it doesn't change as i add more and more data to form_data. Basically im wondering if there is a JS function that can transform my Object() variable into a form which POST will accept and set the $_POST['filepath'] variables that i add to my form_data Object().

Answer 1

You can try sending the data as

{'data':JSON.stringify(form_data)}

Then on server side you will get $_POST['data']

which you can convert into object by using

json_decode($_POST['data']);

I hope this will work
