You'll safely incorporate dynamic elements into web pages using scripting languages, learn how to integrate data from external sources, and build new widgets that users will be able to add to WordPress sidebars and widget areas.

Installing a dedicated code editor/text editor

Most operating systems provide a built-in text editor. While it is possible to create WordPress plugins using such a simple tool, it is highly recommended to install a dedicated code editor on your computer to simplify your plugin development work.

Getting ready

Of course, not all code editors are equal. Here are some of the features that you should look for when selecting a code editing application:

  • PHP syntax highlighting
  • Completion of PHP function names
  • Ability to search across multiple files
  • Ability to highlight all instances of search keyword(s) or selected text
  • Line numbering
  • Ability to resize the editor text or specify a replacement font
  • Possibility of opening multiple files simultaneously

The following editors contain most or all of these key features. Most are free tools, but some are paid applications.
