How to create a WordPress plugin for your web app

In our class’ constructor, let’s register three new actions which are required to add an admin page on WordPress:

• addAdminMenu will add a new page in the WordPress left menu. There will be also a callback to another method containing the page’s content.
• storeAdminData will be called whenever the user clicks the “Save settings” button.
• Addadminscripts will register a new Javascript file to our Wordpress Admin in order to save the form’s data.

Now that we have our options saved, we can create a dynamic widget that will depend on the options set by the user through our admin page. We need to create a new method to our Plugin that will print this code depending on the variables set by the user. To do this, we’ll hook our method to the Wp_Footer action.
