Integrate Doctrine 1.x to Codeigniter 2.0

• Download Doctrine 1.2.3 from http://www.doctrine-project.org/downloads/Doctrine-1.2.3.tgz

• Extract Doctrine then put Doctrine.php and Doctrine folder to directory "system/database"

• Create following folders under "application" folder

  - fixtures/data
  - migrations
  - schema
  - sql

• Add this code into "application/config/database.php"

  /**
  * Doctrine integration
  */
  $db['default']['cachedir'] = "";
  // Create dsn from the info above
  $db['default']['dsn'] = $db['default']['dbdriver'] .
                          '://' . $db['default']['username'] .
                          ':' . $db['default']['password'].
                          '@' . $db['default']['hostname'] .
                          '/' . $db['default']['database'].
                          '' . '?charset=utf-8';
   
  // Require Doctrine.php
  require_once(realpath(dirname(__FILE__) . '/../..') . DIRECTORY_SEPARATOR . 'system/database/Doctrine.php');
   
  // Set the autoloader
  spl_autoload_register(array('Doctrine', 'autoload'));
   
  // Load the Doctrine connection
  Doctrine_Manager::connection($db['default']['dsn'], $db['default']['database']);
   
  // Load the models for the autoloader
  Doctrine::loadModels(realpath(dirname(__FILE__) . '/..') . DIRECTORY_SEPARATOR . 'models');

• Add doctrine.php to "application" folder with this code

  <?php
  require_once('config/database.php');
   
  // Configure Doctrine Cli
  // Normally these are arguments to the cli tasks but if they are set here the arguments will be auto-filled
  $config = array('data_fixtures_path'  =>  dirname(<strong>FILE</strong>) . DIRECTORY_SEPARATOR . '/fixtures',
                  'models_path'         =>  dirname( <strong>FILE</strong> ) . DIRECTORY_SEPARATOR . '/models',
                  'migrations_path'     =>  dirname( <strong>FILE</strong> ) . DIRECTORY_SEPARATOR . '/migrations',
                  'sql_path'            =>  dirname( <strong>FILE</strong> ) . DIRECTORY_SEPARATOR . '/sql',
                  'yaml_schema_path'    =>  dirname( <strong>FILE</strong> ) . DIRECTORY_SEPARATOR . '/schema',
                  'generate_models_options' => array(
                          'generateBaseClasses' => true,
                          'baseClassPrefix' => 'Base_',
                          'baseClassesDirectory' => 'Base',
                          'classPrefixFiles' => false,
                          'classPrefix' => 'Model_',
                          'phpDocName' => '',
                          'phpDocEmail' => ''
                      ));
   
  $cli = new Doctrine_Cli($config);
  $cli->run($_SERVER['argv']);

• Add "require_once APPPATH.'config/database.php';" into "index.php" before "require_once BASEPATH.'core/CodeIgniter'.EXT;"

• Open command line window then go to "application" for run Doctrine CLI

You will see error message "No direct script access allowed"
For tempolary fix this problem, open "application/config/database.php" then add PHP Comment to first line

<?php  if ( ! defined('BASEPATH')) exit('No direct script access allowed');

run CLI again

• Create "schema.yml" into "application/schema" for create sample model.

  Users:
    columns:
      name: string
      email: string

• Create Doctrine model by run command "php doctrine.php build-all"
  
  If you check your database you will see new table in your database.
  

• You can test new Doctrine model by open "application/welcome.php" and modified 'index' action to look like this
  

  function index()
       {
              //$this->load->view('welcome_message');
              $user = new Model_Users();
   
              // assign value
              $user->name = 'John Doe';
              $user->email = 'john@someemail.com';
   
              // save new User
              if($user->trySave()) {
                  echo 'User ID = '.$user->id;
              }
       }

  and then refresh your web site.
  
  and this is sample data in database.
  

Done!
