Simple WP Page Migrations

wp-page-migrate.php

<?php 
/**
 * Plugin Name: wp-page-migrate
 * Description: Edit the plugin to define your pages. Activate this plugin to add the pages to your WP install. 
 * Version:     0.0.1
 * Author:      Alex P. Gates
 * 
 * This is a simple plugin that, when activated, creates pages on a WordPress site if  they don't already exist. 
 * This is useful for keeping local / staging / production in sync and for keeping pages in sync when working 
 * with lots of custom page templates with multiple people on the same project.
 * 
 * There is no settings page for this plugin. 
 * To use it, just define your pages below using WP's array structure for the wp_insert_post() function.
 * You are free to use any parameters that can be passed to wp_insert_post(), so you can define pages or posts,
 * post authors, published dates, parent pages, etc.
 * See the full list here: https://codex.wordpress.org/Function_Reference/wp_insert_post
 * 
 * After you've defined your pages, just activate the plugin. The plugin should be deactivated immediately.
 * Check log.txt for a report of which pages were created and which pages already exist.
 * 
 * The thought behind this is very (very) loosly based on database migration workflows of frameworks such as Laravel.
 * Overall, I find this approach much easier to manage than imports / exports or manually creating WP pages across all your environments.
