What is a Wordpress Plugin?
WordPress
Plugin: A
WordPress Plugin is a program, or a set of one or more functions, written in
the PHP scripting language.
Creating a Plugin
When
creating a WordPress plugin there are some standards to uphold to when doing
so. Below I’ll outline some key points to remember when creating your own.
Plugin Files
Typically
a plugin lives within its own folder under wp-content/plugins/ inside your
WordPress installation. There is usually at least one PHP file that is
typically named after the plugin. So if your plugin was named first-plug then
your PHP file name would most likely be first-plug.php. Using a unique name is
crucial so no two plugins use the same name.
Standard Plugin File
A plugin
must contain a bit of meta information which tells WordPress what it is and how
to handle it within your website. Plugins can be installed, deleted, activated,
and inactivated. A standard header is introduced below to establish your
plugin’s presence. The parameters shown will tell WordPress how to optimise it
within your website and WordPress admin area.
