README

This is an oop wrapper for wordpress nonces functionality.

Installation

If you have not done that already add composer autoloader to your wordpress main index.php:

require_once('vendor/autoload.php');

Add to your composer.json in require this: "radix/nonce-oop": "1.0 and run composer update.

Usage

Initialize the facade.

At the beginning of the file you want to use nonces in put:

use radix\NonceOop\NonceFacade;

then you can instantiate a common facade via:

$facade = new NonceFacade('testAction');

Without a second argument it will use the default SimpleNonce variant. If you want you can also use RequestNonce and AjaxNonce, just add them to the use declaration and inject their insances into the facade like that:

use radix\NonceOop\{NonceFacade, RequestNonce};

// ...

$facade = new NonceFacade('testAction', new RequestNonce());

Use the interface.

After that is done you have four methods that you can use:

$simpleNonce  = $facade->create();
$fieldNonce   = $facade->createField();
$urlNonce     = $facade->createUrl('http://example.com');
$isNonceValid = $facade->check($simpleNonce);

The methods wrap original WordPress nonce functions.

• create method creates a simple 10-character string,
• createField method gives you HTML string containing hidden input field with a nonce in it. Refer to the method interface to see what options you can use.
• createUrl method gives you an URL with a nonce appended to URL's query. Refer to the method interface to see what options you can use.
• check method validates the nonce. When used with SimpleNonce it only checks the string, other classes check the $_REQUEST superglobal.

Extending

You can add your own class that implements NonceServiceInterface and inject it into the facade on initialization.

Tests

In order to run tests type:

vendor/bin/phpunit --bootstrap vendor/autoload.php vendor/radix/nonce-oop/tests/src

Please note that you need to have PHPUnit installed.
