Database Connection in Zend Framework - zend-framework

Question

I am new to ZF. I have coded my application.ini here it is:
[development]
includePaths.library = APPLICATION_PATH "/../library"
bootstrap.path = APPLICATION_PATH "/Bootstrap.php"
bootstrap.class = "Bootstrap"
appnamespace = "Application"
resources.frontController.controllerDirectory = APPLICATION_PATH "/controllers"
resources.frontController.params.displayExceptions = 0
resources.view.encoding = "utf-8"
resources.layout.layoutPath = APPLICATION_PATH "/layouts/scripts"
phpSettings.display_startup_errors = 1
phpSettings.display_errors = 1
phpSettings.display_startup_errors = 1
phpSettings.display_errors = 1
resources.frontController.params.displayExceptions = 1
resources.DB.adapter = "pdo_mysql"
resources.DB.params.host = "localhost"
resources.DB.params.username = "root"
resources.DB.params.password = ""
resources.DB.params.dbname = "xyz"
here is my index.php
defined('APPLICATION_PATH')
|| define('APPLICATION_PATH', realpath(dirname(__FILE__) . '/../application'));
// Define application environment
defined('APPLICATION_ENV')
|| define('APPLICATION_ENV', (getenv('APPLICATION_ENV') ? getenv('APPLICATION_ENV') : 'development'));
// Ensure library/ is on include_path
set_include_path(implode(PATH_SEPARATOR, array(
realpath(APPLICATION_PATH . '/../library'),
get_include_path(),
)));
/** Zend_Application */
require_once 'Zend/Application.php';
// Create application, bootstrap, and run
$application = new Zend_Application(
APPLICATION_ENV,
APPLICATION_PATH . '/configs/application.ini'
);
$application->bootstrap()->run();
and here is my bootstrap.php
class Bootstrap extends Zend_Application_Bootstrap_Bootstrap{
protected function _initDoctype(){
$this->bootstrap('view');
$view = $this->getResource('view');
$view->doctype(Zend_View_Helper_Doctype::HTML5);
}
}
now firstly i did my connection like this
$params = array('host' => 'localhost',
'username' => 'root',
'password' => '',
'dbname' => 'xyz'
);
$DB = new Zend_Db_Adapter_Pdo_Mysql($params);
$DB->setFetchMode(Zend_Db::FETCH_OBJ);
Zend_Registry::set('DB',$DB);
Later in my queries I used this to retrieve records:
$registry = Zend_Registry::getInstance();
$DB = $registry['DB']; and than my query
Now as I have changed my setting mean including bootstrap and application.ini how to achieve the same as I did? Because in my app everything is like that..
Now I am getting this error.
Notice: Undefined index: DB in
C:\xampp\htdocs\xyz\application\controllers\LoginController.php on line 59
Fatal error: Call to a member function select() on a non-object in C:\xampp\htdocs\xyz\application\controllers\LoginController.php on line 64
Line #59 is
$registry = Zend_Registry::getInstance();
$DB = $registry['DB'];
Line #64 is
$select = $DB->select()
->from(array('p' => 'phone_service'))
->join(array('u' => 'user_preferences'), 'u.phone_service_id = p.phone_service_id')
->where('u.user_preferences_name = ?', 'is_user_package_active')
->where('p.user_id = ?', $user_id);
Edited
if($result->isValid()){
$data = $authAdapter->getResultRowObject(null,'password');
$auth->getStorage()->write($data);
$this->_redirect('/login/controlpannel');}
Now my query can't find $user_id here
$data = Zend_Auth::getInstance()->getStorage()->read();
$user_id = $data->user_id;
$DB = Zend_Db_Table_Abstract::getDefaultAdapter();
$select = $DB->select()
->from(array('p' => 'phone_service'))
->join(array('u' => 'user_preferences'), 'u.phone_service_id = p.phone_service_id')
->where('u.user_preferences_name = ?', 'is_user_package_active')
->where('p.user_id = ?', $user_id);
That's why I am getting this error

Answer 1

By default when using
resources.db.*
in your application.ini a default adapter with these settings will be set up (and by default be used in Zend_Db_Table).
As the adapter is already registered as default adapter in Zend_db_Table_Abstract by default, accessing it is as easy as using:
$db = Zend_Db_Table_Abstract::getDefaultAdapter();
Another way to get it is to fetch it from the bootstrap-instance, which goes something like this (according to Reference Manual):
$front = Zend_Controller_Front::getInstance();
$bootstrapResource = $front->getParam('boostrap')->getPluginResource('db');
$db = $boostrapResource->getDbAdapter();

The Zend_Registry is a object so you should be doing:
$registry = Zend_Registry::getInstance();
$DB = $registry->DB;
