syntax for including $_SERVER filepath in jquery ajax url?

Question

i am sending data to a url using jquery ajax. i want to place the absolute url using php $_SERVER. what is the syntax to do this?

this is the file path that goes in the URL

$_SERVER['DOCUMENT_ROOT']."/folder/file_name.php"

this is the function that the file path goes in

$.ajax({
            type: "GET",
            url: "",
            data: 'time='+ visitortimezone,
            success: function(){
                location.reload();
            }
        });

what is the syntax for this?

If the target php file is in the same domain as the page you're running the ajax from, you can simply use a relative path in the url I guess. — Fabrício Matté

If you really want to get document root from PHP, you can try something like this:

HTML: (Place your document root in hidden text field)

<input type='hidden' name='baseurl' id='baseurl' value='<?php echo  $_SERVER['DOCUMENT_ROOT'];?>'>

jQuery: (Get document root in jQuery from hidden text field)

       $.ajax({
            type: "GET",
            url:  $('#baseurl').text() + "/folder/file_name.php",
            data: 'time='+ visitortimezone,
            success: function(){
                location.reload();
            }
        });

If you are writing your JavaScript in PHP files, you can also try this:

       $.ajax({
            type: "GET",
            url:  "<?php echo $_SERVER['DOCUMENT_ROOT'] . '/folder/file_name.php';?>",
            data: 'time='+ visitortimezone,
            success: function(){
                location.reload();
            }
        });

You can also get hostname in JavaScript too:

document.location.hostname

+1 for listing basically all possible answers. Instead of using a hidden input field, you can also just echo a global var in the document: echo '<script type="text/javascript">var url=' . $_SERVER['DOCUMENT_ROOT'] . ';</script>'; to store the PHP's $_SERVER['DOCUMENT_ROOT'], but there isn't much point to that if you can just use document.location.hostname as well.

I also echoed the whole script tag inside the php, I guess it'd be easier to put it in the html and just echo the var's value itself but yes, I'm sure you already knew that. :P No problem.
