JavaScript - How to use variable data parsed into PHP?

Question

I have a form that has data that is parsed to a PHP file. I was wondering how to use the data that is also sent in the variable myData. If the form serializes then I can use the $_GET['add_album'], but how do I use myData in PHP? I want to echo the data in my PHP file. Here is my AJAX:

var div = document.getElementById("hidden_div");
                    var myData = div.textContent;
                    /*var pathh = '<?php echo $pathh ?>';*/
                    alert(JavaScriptAlert); 
                    $.ajax
                    (
                        {
                            url:"add_album.php",
                            type: "GET",
                            data: {myData: myData, form: $('#form3').serialize()}, 
                            success:function(result)
                            {
                                alert(result);
                            }
                        }
                    );

and my PHP:

<?php
echo myData.'\\'$_GET['add_album']; //need to echo out the data inside the "myData" variable
mkdir(myData.'\\'$_GET['add_album']);
?>

It is like you have the add_album but change the index to myData. — user3783243

echo myData.'\\'.$_GET['add_album']; , ditto mkdir you should be getting syntax errors, but may not see them — user9487972

data "is converted to a query string, if not already a string."

Usually, to send form data, you'd use data: $('#form3').serialize(). You have {myData: myData, form: $('#form3').serialize()} though, which gets converted to

myData=some_divtext&form=serialized_form_content

Which means on the server, you now have $_GET['myData'] and $_GET['form']

I don't think that's what you want, mostly because you'd have to manually parse the form query string, therefore my suggestion would be

add <input name="mydata" type="hidden"> to your form

instead of

var div = document.getElementById("hidden_div");
var myData = div.textContent;

use

$('#form3 [name=mydata]').val($('#hidden_div').text());

send data: $('#form3').serialize()
