Requirements

Prerequisite	How to check	How to install
PHP >= 5.4.x	php -v	php.net

---

Installing

Clone the git repo - git clone https://github.com/cuisine-wp/wp-table-migrations.git or install with composer:

composer require chefduweb/wp-table-migrations

After you have all the files you need to install wp-table-migrations like a regular WordPress plugin:

1. move the files to wp-content/plugins
2. get into the WordPress admin and go to plugins
3. activate WP Table Migrations.

Getting Started

Creating database migrations with the power of WP Table Migrations is quite easy; you just create a class that extends

\TableMigrations\Migrations\Migration;

And use WP Cli to run the command:

wp tables migrate

That's it! See our examples for more:

Quick examples

Here are a few quick examples on how WP Table Migrations will be making your life easier:

Creating and dropping custom tables

This actually looks exactly the same as Laravel's database migrations, with the exception of having to extend a different class and create an instance of that class at the bottom.

namespace MyPlugin\Database;

use TableMigrations\Wrappers\Schema;
use TableMigrations\Database\Blueprint;
use TableMigrations\Migrations\Migration;

class ProductMetaMigration extends Migration{


    /**
     * Put the table up
     *
     * @return void
     */
    public function up()
    {
        Schema::create( 'product_meta', function( Blueprint $table ){
            $table->increments( 'id' )->unique();
            $table->integer( 'product_id' )->unsigned();
            $table->string( 'image_url' )->nullable();
            $table->integer( 'position' );
            $table->float( 'price' );
            $table->integer( 'stock' );
        });         
    }

    /**
     * Default down function
     *
     * @return void
     */
    public function down()
    {
        Schema::drop( 'product_meta' );
    }

}


\MyPlugin\Database\ProductMetaMigration::getInstance();

In this example a table named product_meta is created or destroyed, depending on which direction the migration is running.

Creating columns

You can create a lot of different column types with Table Migrations. Here's a list:

Command	Description
$table->bigInteger('votes');	BIGINT equivalent for the database.
$table->binary('data');	BLOB equivalent for the database.
$table->boolean('confirmed');	BOOLEAN equivalent for the database.
$table->char('name', 4);	CHAR equivalent with a length.
$table->date('created_at');	DATE equivalent for the database.
$table->dateTime('created_at');	DATETIME equivalent for the database.
$table->decimal('amount', 5, 2);	DECIMAL equivalent with a precision and scale.
$table->double('column', 15, 8);	DOUBLE equivalent with precision, 15 digits in total and 8 after the decimal point.
$table->float('amount', 8, 2);	FLOAT equivalent for the database, 8 digits in total and 2 after the decimal point.
$table->increments('id'); } Incrementing ID (primary key) using a "UNSIGNED INTEGER" equivalent.
$table->integer('votes');	INTEGER equivalent for the database.
$table->longText('description');	LONGTEXT equivalent for the database.
$table->mediumInteger('numbers');	MEDIUMINT equivalent for the database.
$table->mediumText('description');	MEDIUMTEXT equivalent for the database.
$table->smallInteger('votes');	SMALLINT equivalent for the database.
$table->string('email');	VARCHAR equivalent column.
$table->string('name', 100);	VARCHAR equivalent with a length.
$table->text('description');	TEXT equivalent for the database.
$table->time('sunrise');	TIME equivalent for the database.
$table->tinyInteger('numbers');	TINYINT equivalent for the database.
$table->timestamp('added_on');	TIMESTAMP equivalent for the database.

Saving & Fetching data

WordPress has all sorts of functions for saving and retrieving your data from the 12 database tables it already knows. We wouldn't want to leave you hanging, so we created a simple wrapper for your custom tables as well.

use TableMigrations\Wrappers\Record;

//inserting:
Record::insert( 'product_meta', $data );

//updating:
Record::update( 'product_meta', $id, $data );

//removing:
Record::delete( 'product_meta', $id );

The record class can handle table inserts, updates and upserts, but also fetches:

//find all product meta associated with this product:
Record::find( 'product_meta' )
        ->where(['product_id' => $product_id ])
        ->results();

//find the first product meta where the price is 0
Record::find( 'product_meta' )
        ->where([

            'product_id' => $product_id,
            'price' => 0

        ])->first();

Adding WHERE clauses results in "AND" queries by default. Currently we're still working on "OR" support. Record::find() queries will return either an Array or null if the query returned no table rows.
