You can use this client to easily query the Mendeley API (http://dev.mendeley.com/docs/) from your PHP code. It accepts URLs from "user specific resources", handles the Authentication via OAuth and returns a PHP object with its results. The authentication is cached.

You need to have SimpleTest installed to run the tests.

1. Run webroot/mendeleyapi/getAccessToken.php once to get your Mendeley access token. You only have to do that once. It should redirect you to the Mendeley page where you login and saves the token under /mendeleyapi/cache/access_token_SOMESTRING.

2. Runs with Simpletest. Point your browser to webroot/mendeleyapi/tests/all_tests.php or with the shell:

   $ php path/to/mendeleyapi/tests/all_tests.php

Copy Configuration.sample.php to Configuration.php and input your Mendeley consumer and secret. If you don't have one, obtain it from the Mendeley developers site.

Use the library stand-alone like this:

require_once 'path/to/mendeleyapi/Mendeley.php';
$mendeley = new Mendeley();

// GET request to look up things
$result = $mendeley->get('groups/12345'); // returns a PHP object with all documents of the group
$result = $mendeley->getCollection('groups/12345'); // similar to above, only that enriches the result with the document info for each document

// POST request to change things, in this case to add a document to a group
$doc = new MendeleyDoc();
$doc->type = 'Generic';
$doc->title = 'Example Title';
$doc->authors = array('Jakob Stoeck');
$doc->group_id = 504091;
$mendeley->post('documents/', $doc->toParams());

// DELETE
$mendeley->delete('documents/12345');

For convenience a copy of the OAuth Library is pre-installed
