Answer 1

Recently tried to sort out with this question. Here is simple solution:

It needs to have script on your server to generate signature, in this case it is file named "add.php". It should contain something like:

<?php
    define('CINCDIR', './inc/cloudinary/'); // path to cloudinary lib folder

    require_once(CINCDIR . 'Cloudinary.php');
    require_once(CINCDIR . 'Api.php');

    if(isset($_GET['data']))
    {
        echo \Cloudinary::api_sign_request($_GET['data'], '[PUT CLOUDINARY API SECRET HERE]');
    }
?>

Replace [PUT CLOUDINARY API SECRET HERE] with your cloudinary api secret.

This script needs cloudinary's PHP integration library. You should be able to download it from the following link: https://github.com/cloudinary/cloudinary_php/tarball/master . Copy all files from the src folder into your PHP project and include Cloudinary's PHP classes in your code:

require_once(CINCDIR . 'Cloudinary.php');
require_once(CINCDIR . 'Api.php');

Also, about JavaScript from your example above, you don't need to pass predefined parameters here:

url     : "http://localhost/add.php?public_id=sample_image&timestamp=1315060510"

Just URL of your script, in this case it is " http://localhost/add.php ":

url     : "http://localhost/add.php"

Parameters added automatically, when generateSignature function is called.
