How WordPress Plugins Are Developed?

WordPress plugins are programmed using a plugin development kit, or a programming environment that makes it easy for developers to create new plugins. To create a plugin, you need to create a plugin file (.php) and then create a plugin directory.

The plugin file contains the plugin’s code and requires the plugin’s main() function to be defined. The plugin directory stores the plugin’s files and requires the plugin’s init() function to be defined.

To install a plugin, you need to copy the plugin’s files to the WordPress plugin directory and then activate the plugin using the WordPress plugin activation function. To uninstall a plugin, you need to remove the plugin’s files from the WordPress plugin directory and then disable the plugin using the WordPress plugin disable function.
