README

A WordPress library for managing database table schema upgrades and data seeding.

Installation

• composer require enshtein/wp-migrations
• bootstrap the package by adding \Enshtein\WpMigrations\Migrate::instance(); to an mu-plugin.

Migrations

By default, the command will look for migration files in migrations directory alongside the vendor folder.

Use

Simply run wp migrate on the command line using WP CLI and any migrations not already run will be executed.

Create a migration file

wp migrate create add_price_table

<?php

use Enshtein\WpMigrations\Migration;

return new class extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        global $wpdb;

        // up migration code
    }

    /**
     * Reverse the migrations.
     *
     * @return void
     */
    public function down()
    {
        global $wpdb;

        // down migration code
    }
};

wp migrate create add_price_table --table=price

<?php

use Enshtein\WpMigrations\Migration;

return new class extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        global $wpdb;

        $_sql = "CREATE TABLE `{$wpdb->prefix}price` (
           `id` int(10) NOT NULL auto_increment,
           PRIMARY KEY (id)
        ) {$this->collation()}";
				
        dbDelta($_sql);
    }

    /**
     * Reverse the migrations.
     *
     * @return void
     */
    public function down()
    {
        global $wpdb;

        $wpdb->query("DROP TABLE IF EXISTS `{$wpdb->prefix}price`");
    }
};
