In this article I'm going to walk you through process of creating Wordpress plugins. First I'm going to talk about some of the basic concepts in Wordpress plugin development like the actions, hooks, and API's that makes up Wordpress. Then were going to build a plugin where we apply some of the concepts and best practices in developing Wordpress plugins.

###Prerequisites

In order to fully benefit from this tutorial you should have a basic knowledge on PHP. As Wordpress is running on PHP and most of the code that we will be writing will be on PHP. A little bit of knowledge on HTML, CSS and JavaScript is also helpful but not required for this tutorial.

	<?php
	/**
	* Delete a post meta transient.
	*/
	function delete_post_meta_transient( $post_id, $transient, $value = null ) {
	global $_wp_using_ext_object_cache;

	$post_id = (int) $post_id;

	do_action( 'delete_post_meta_transient_' . $transient, $post_id, $transient );

	# ----------------------
	# installing dnsmasq and enable daemon
	# ----------------------
	brew install dnsmasq
	sudo cp -v $(brew --prefix dnsmasq)/homebrew.mxcl.dnsmasq.plist /Library/LaunchDaemons
	# ----------------------
	# adding resolver for vbox domain
	# ----------------------
	[ -d /etc/resolver ] \|\| sudo mkdir -v /etc/resolver
	sudo bash -c 'echo "nameserver 127.0.0.1" > /etc/resolver/vbox'

	# ~/.gitconfig
	# Add this to your global git configuration file
	# Change phpstorm to webstorm, if you use that.

	# Diff and merge tool changes
	# Run `git difftool <directory/file>...` or `git mergetool <directory/file>...`
	[merge]
	tool = phpstorm
	[diff]
	tool = phpstorm

	<?php
	/**

	git log --pretty="%ad\|%an\|%s" --date=short \|
	while IFS='\|' read date author message
	do
	printf '%s %-20s %s\n' "$date" "$author" "$message"
	done

	<?php
	/*
	Plugin Name: My Plugin
	Description: Test dbDelta
	Version: 0.1
	*/

	// Upgrade when the admin loads
	add_action( 'admin_init', 'myplugin_upgrade' );
