WordPress Nonce's in Object Oriented way

Worpress Nonces stand for "number used once", are used in requests (saving options, form posts, Ajax requests, actions, and so on) to stop unauthorised access by generating a secret key. This secret key is generated prior to generating a request (that is from post). The key is then passed in the request to your script and verified to be the same key before anything else is processed.

In General nonce's are a built in security tool for WordPress that you should always utilize to make sure your plugins themes are as secure as can be

This Repository shows one posible way of using nonces in object oriented way with PHP

Instalation

First thing: If you are using Windows for developing WP themes and plugins i would really suggest you to use Vagrant/vccw (Development environment for Wordpress) VCCW. It will really help you on the general process and specially with phpunit testing process.

Download, clone or use composer to install the plugin and test it using the bellow codes:

Create Field nonce

$nonce = new WpNonce();
$nonce->setAction("name_of_my_action");
$nonce->setName("name_of_nonce_field");
$nonce->ax_nonce_field_generator();

Create URL Nonce

$nonce_url = new WpNonce();
$nonce_url->setUrl('/test/?action=delete&ID=$id');
$nonce_url->setAction("url_nonce_delete_action");
$nonce_url->setName("url_nonce_delete_name");
echo $post->post_title . "<a href=".  $nonce_url->ax_nonce_url_generator().">Delete</a><br>";

Create Generl nonce

$nonce_general = new WpNonce();
$nonce_general->setAction("ax_general_none");
$nonce_general->ax_general_nonce_generate();

Verify Nonce

$verify_nonce = new WpNonce();
$nonce_boolean_value = $verify_nonce->ax_nonce_verify($_POST['name_of_nonce_field'], "name_of_my_action");

if($nonce_boolean_value == 0)
   {
    /* Show error message*/
   }
   else 
   {
     /*Proceed with insertation, deletation, update ... */
   }
