Question

我使用的是适用于CodeIgniter 2的迁移代码，但它们不适用于CodeIgniter 3

我已经阅读了与我的问题相似的大多数问题，但是找不到答案。

........

class Migration_Create_users extends CI_Migration
{
   public function up()
   {
       $this->dbforge->add_field([
           'id'       => [
               'type'           => 'INT',
               'constraint'     => 11,
               'unsigned'       => true,
               'auto_increment' => true,
           ],
           'email'    => [
               'type'       => 'VARCHAR',
               'constraint' => '100',
           ],
           'password' => [
               'type'       => 'VARCHAR',
               'constraint' => '128',
           ],
           'name'     => [
               'type'       => 'VARCHAR',
               'constraint' => '100',
           ],
       ]);
       $this->dbforge->add_key('id', true);
       $this->dbforge->create_table('users');
   }
   public function down()
   {
       $this->dbforge->drop_table('users');
   }
}

class Migration extends Admin_Controller
{
    public function __construct()
    {
        parent::__construct();
    }
    public function index()
    {
        $this->load->library('migration');
        if (!$this->migration->current()) {
            show_error($this->migration->error_string());
        } else {
            echo 'Migration worked!';
        }
    }
}

//迁移配置

defined('BASEPATH') or exit('No direct script access allowed');
$config['migration_enabled']     = true;
$config['migration_type']        = 'sequential';
$config['migration_table']       = 'migrations';
$config['migration_auto_latest'] = false;
$config['migration_version']     = 001;
$config['migration_path']        = APPPATH . 'migrations/';

我希望运行代码，然后在数据库中创建表

请使用以下功能

class Migrate extends CI_Controller{

    public function index($version){
        $this->load->library("migration");

      if(!$this->migration->version($version)){
          show_error($this->migration->error_string());
      }   
    }
}

如何在Codeigniter上进行迁移？
