Overview of this book

If you can write WordPress plug-ins, you can make WordPress do just about anything. From making the site easier to administer, to adding the odd tweak or new feature, to completely changing the way your blog works, plug-ins are the method WordPress offers to customize and extend its functionality. This book will show you how to build all sorts of WordPress plug-ins: admin plug-ins, Widgets, plug-ins that alter your post output, present custom "views" of your blog, and more. WordPress Plug-in Development (Beginner's Guide) focuses on teaching you all aspects of modern WordPress development. The book uses real and published WordPress plug-ins and follows their creation from the idea to the finishing touches, in a series of carefully picked, easy-to-follow tutorials. You will discover how to use the WordPress API in all typical situations, from displaying output on the site in the beginning to turning WordPress into a CMS in the last chapter. In Chapters 2 to 7 you will develop six concrete plug-ins and conquer all aspects of WordPress development. Each new chapter and each new plug-in introduces different features of WordPress and how to put them to good use, allowing you to gradually advance your knowledge. This book is written as a guide to take your WordPress skills from the very beginning to the level where you are able to completely understand how WordPress works and how you can use it to your advantage.

Tinkering with WordPress backend menus


Since we added the URL page under the Write menu, and there is already a Link page there (for adding links to the blogroll), we would like to remove the Link page from the menus to prevent confusion.

You can easily do this (in fact, you can totally rearrange WordPress menus in any way you like).

Time for action — Remove 'Link' from the Write page

  1. Removing an item from a menu is a simple matter. Lets add this code to the admin_menu() function:

    // Hook to admin menu
    function admin_menu() {
    global $submenu;
    // remove 'Link' from Write menu
    unset($submenu['post-new.php'][15]);
    // submenu pages
    add_submenu_page('post-new.php', __('Add Photo',$this- >plugin_domain) , __('Photo', $this->plugin_domain) , 1 , 'add-photo', array(&$this, 'display_form') );
    
  2. That's all! The link page no longer shows in the menu.

What just happened?

We removed the Link page from the menus by unsetting it from the submenu array.

WordPress holds the entire backend menu structure...
