wp-cli-mig

General migration command for WP-CLI

Example migration

1. Create migration script

   // filename: migrations/1_FirstMigration.php
   namespace WpCliMigrate;
   
   use Foogile\WpCli\Migrate\MigrationInterface;
   
   class FirstMigration implements MigrationInterface
   {
   
       public function up()
       {
           // Do some work using WordPress API
       }
   
       public function down()
       {
           // Undo some work using WordPress API
       }
   
   }
   

2. Move into folder migrations and execute migrations using WP-CLI

       # Migrate to version 1
       wp --require=/path/to/command.php mig to 1
   
       # Migrate to version 2
       wp --require=/path/to/command.php mig to 2
   
       # Revert all migrations
       wp --require=/path/to/command.php mig to 0
   
       # Status
       wp --require=/path/to/command.php mig status
   

For migrations that should stop execution, throw exceptions from up/down-methods. I.e. a non-reversable migration will typically refuse a down()-operation: throw new \Exception("Cannot rollback migration").
