Variable changes when pass from javascript to php

Question

so i have this code

 $('#sepia').click(function () {
    var filePathName = tempFilePath;
    alert(filePathName);
    $.ajax({
        type: 'POST',
        url: 'php/sepia.php',
        data: {
            FilePath: filePathName
        },
        success: function (data) {
            pictureReset();
        }
    });
});

alert(filePathName) has the correct value test.jpg but as soon as its passed with

            data: {
                FilePath: filePathName
            }

the value is changes to incomprehensible text like this jhSerZR6i1T952C3bk7vEOGCj8Pz_tBYtuHcgrgj81A.

even if i replace filePathName with 'hp_2.jpg` i still get the same random letter message

never mind found the error. wasn't anywhere near that bit of code but when i came back to the script to use the file path name. added +"" at the end and fixed it :)

First guess? You have a reference to an /image/. Your alert statement is stringifying it, turning it into just a file name, but the POST is actually upload the image iself. — Jeremy J Starcher

If my guess is right, it should. You could add a console.log(filePathName) right before your alert and see what it gives you. — Jeremy J Starcher

it returns the correct filepath name as well, i added the '' and i still get that long string :( — hahaha

OK.. second try: Look at your debugging tools Network tab and see what is actually being sent. If the string test.jpg is being sent, then the problem has to be on the server-side PHP code. — Jeremy J Starcher

ok, lets try some else....

usual it's the same but it may gives a other result...

var tempFilePath = 'test.jpg';
$('#sepia').click(function () {
    var filePathName = tempFilePath;
    $.post('php/sepia.php', 
    {
        data:   {
                    //FilePath: filePathName changed to
                    fpath: filePathName
                }
    }).done(function(response){
        console.log(response);
    });
});

and add this to sepia.php:

<?php
    echo "<pre>";
    print_r($_POST);
    echo "</pre>";
    die();

    // rest of your code
?>

this should return

array( 
       "FilePath" => "test.jpg" 
);

in the console
