Using Zend_Layout with the Zend Framework MVC

simple example of zend_layout.

First we define some defined default.

defined('APPLICATION_PATH')
 || define('APPLICATION_PATH', 
     realpath(dirname(dirname(__FILE__)) . '/application'));
define('CONFIG_PATH', realpath(APPLICATION_PATH . '/configs'));
define('LAYOUT_PATH', realpath(APPLICATION_PATH . '/layouts'));

define('PUBLIC_URL', '/zftut/public');

The next, we create LayoutController.

<?php
class LayoutController extends Zend_Controller_Action{
 
 public function indexAction(){
  $options = array(
       'layoutPath'=> LAYOUT_PATH . '/scripts',
       'layout' => 'index',
       'viewSuffix' => 'phtml'
      );
  Zend_Layout::startMvc($options);
 }
 
 public function mainAction(){
  $options = array(
       'layoutPath'=> LAYOUT_PATH . '/scripts',
       'layout' => 'main',
       'viewSuffix' => 'php'
      );
  Zend_Layout::startMvc($options);
 }
 
 public function changeLayoutAction() {
  $this->_helper->layout->setLayout('main2');
 }
 
 public function disableAction(){
  
  $this->_helper->layout->disableLayout();
 }
 
 public function noViewAction(){
  
  $this->_helper->viewRenderer->setNoRender();
 }
 
 public function placeHolderAction(){
  $this->view->placeholder('Zend_Layout')->foo = ' This is a test';  
  $this->_helper->layout->setLayout('index');
 }
}

File layout in application\layouts\scripts\index.phtml

<?php echo $this->doctype() ?>
<html>
<head>
    <?php echo $this->headTitle() ?>
    <?php echo $this->headMeta() ?>
    <?php echo $this->headLink() ?>
    <?php echo $this->headScript() ?>
</head>
<body>
    <h1>Layout.phtml</h1>
    <?php echo $this->layout()->content ?>
    <?php echo $this->layout()->foo;?>
</body>
</html>

Read and write configuration files the format xml with Zend_Config

1. Read ini file.

I have a configuration file /application/configs/db.ini as follows:

<?xml version="1.0" encoding="UTF-8"?>
<configdata>
 <infomation>
  <webhost>www.example.com</webhost>
  <database>
   <adapter>pdo_mysql</adapter>
   <params>
    <host>localhost</host>
    <username>root</username>
    <password>root</password>
    <dbname>zftraining</dbname>
   </params>
  </database>
 </infomation>
 <data extends="infomation">
  <webhost>www.example.com</webhost>
  <database>
   <adapter>pdo_mysql</adapter>
   <params>
    <host>localhost</host>
    <username>vanlanh</username>
    <password>123456</password>
    <dbname>zftraining</dbname>
   </params>
  </database>
 </data>
</configdata>

We use the class to read file Zend_Config_Xml db.xml

  
 public function xmlAction(){
  $xml = CONFIG_PATH . '/db.xml';
  $section = 'data';
  $config = new Zend_Config_Xml($xml, $section);
  echo '<br>' . $config->webhost;
  echo '<br>' . $config->database->adapter;
  echo '<br>' . $config->database->params->username;
  echo '<br><hr>';
  echo '<pre>';
  print_r($config->toArray());
  echo '</pre>';
 }

Output:

www.example.com
pdo_mysql
vanlanh
Array
(
    [webhost] => www.example.com
    [database] => Array
        (
            [adapter] => pdo_mysql
            [params] => Array
                (
                    [host] => localhost
                    [username] => vanlanh
                    [password] => 123456
                    [dbname] => zftraining
                )

        )

)

2.Write xml file

 public function writeXmlAction(){
  $data = array(
    'global'=>array(
     'smtp'=>array(
      'parameters'=>array(
       'host'  => "smtp.example.com",
       'port'  => "587",
       'username' => "jeky11",
       'password' => "hyd3",
       'security' => "tls",
       ) 
      )   
     ),
      'data'=>array(
       'version' => "1.1"
     )
    );
  $config = new Zend_Config_Writer_Xml();
  $filename = CONFIG_PATH . '/my01.xml';
  $objConfig = new Zend_Config($data);
  $config->write($filename,$objConfig);
 }

My01.xml output file:

<?xml version="1.0"?>
<zend-config xmlns:zf="http://framework.zend.com/xml/zend-config-xml/1.0/">
  <global>
    <smtp>
      <parameters>
        <host>smtp.example.com</host>
        <port>587</port>
        <username>jeky11</username>
        <password>hyd3</password>
        <security>tls</security>
      </parameters>
    </smtp>
  </global>
  <data>
    <version>1.1</version>
  </data>
</zend-config>

Configuration multi modules in Zend Framework

1. Create the basic structure for the application

2. Create a detailed structure for each module (Admin & Default)

3. Configuration file application\index.php

<?php
defined ( 'APPLICATION_PATH' ) 
	|| define ( 'APPLICATION_PATH', 
		realpath ( dirname ( __FILE__ ) . '/application' ) );

defined ( 'APPLICATION_ENV' ) 
	|| define ( 'APPLICATION_ENV', 
		(getenv ( 'APPLICATION_ENV' ) ? getenv ( 'APPLICATION_ENV' ) : 'developer') );

set_include_path ( implode ( PATH_SEPARATOR, array 
						(realpath ( dirname ( __FILE__ ) . '/library' ),get_include_path (), ) ) );

require_once 'Zend/Application.php';

$application = new Zend_Application ( APPLICATION_ENV, 
			realpath ( APPLICATION_PATH . '/configs/application.ini' ) );
$application->bootstrap ()->run ();

4. Configuration file application\.htaccess

RewriteEngine On
RewriteCond %{REQUEST_FILENAME} -s [OR]
RewriteCond %{REQUEST_FILENAME} -l [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^.*$ - [NC,L]
RewriteRule ^.*$ index.php [NC,L]

5.Install file contains application configuration application\configs\application.ini

[production]
phpSettings.display_status_errors	=0
phpSettings.display_errors			=0
phpSettings.default_charset			="UTF-8"
phpSettings.date.timezone			="Asia/Ho_Chi_Minh"

bootstrap.path		=APPLICATION_PATH "/Bootstrap.php"
bootstrap.class		="Bootstrap"
resources.frontController.moduleDirectory = APPLICATION_PATH "/modules"
resources.modules = ""

resources.layout.layout = "layout"
resources.layout.layoutpath = APPLICATION_PATH "/layouts"

resources.db.adapter = "PDO_MYSQL"
resources.db.params.host = "localhost"
resources.db.params.username = "root"
resources.db.params.password =
resources.db.params.dbname = "test"

[developer : production]
phpSettings.display_status_errors	=1
phpSettings.display_errors			=1

6. Set the file contents application\layouts\layout.phtml

<?php echo $this->doctype(); ?>
<html>
<head>
   <?php echo $this->headMeta(); ?>
   <?php echo $this->headTitle(); ?>
   <?php echo $this->headLink(); ?>
</head>
<body>

<?php echo $this->layout()->content; ?>

</body>
</html>

7. Create initialization files for all applications application\Bootstrap.phpl

<?php
class Bootstrap extends Zend_Application_Bootstrap_Bootstrap
{
   
}

8. Create files initializate for Admin module application\modules\admin\Bootstrap.php

<?php
class Admin_Bootstrap extends Zend_Application_Module_Bootstrap 
{
   
}

9. IndexController inclusion of the Admin module - application\modules\admin\controllers\IndexController.php

<?php
class Admin_IndexController extends Zend_Controller_Action {
   
   public function indexAction(){
      $this->view->show = 'Zend Framework training course in www.zend.vn<br>Back-End';
      
   }
   
}

10. Show indexAction content in the Admin module IndexController

- application\modules\admin\views\scripts\index\index.phtml

<h2><?php echo $this->show;?></h2>

11. Create files initializate for Default module application\modules\default\Bootstrap.php

<?php
class Default_Bootstrap extends Zend_Application_Module_Bootstrap 
{
   
}

12.Inclusion of Default IndexController module - application\modules\default\controllers\IndexController.php

<?php
class IndexController extends Zend_Controller_Action {
   
   public function indexAction(){
      $this->view->show = 'Zend Framework training course in www.zend.vn<br>Front-End';
      
   }
}

13. Display the contents of the Default IndexController indexAction in module

- application\modules\default\views\scripts\index\index.phtml

<h2><?php echo $this->show;?></h2>

Hey Facebook Developers! This video is the first in a new series of how-to videos we'll be doing to show you how to make your web site or application more social with Facebook Connect.

Read and write configuration files the format ini with Zend_Config

1. Read ini file.

I have a configuration file /application/configs/db.ini as follows:

[information]

webhost    =www.example.com
database.adapter  =pdo_mysql
database.params.host =localhost
database.params.username=root
database.params.password=root
database.params.dbname =zftraining

[data:information]

webhost     =www.example.com
database.adapter  =pdo_mysql
database.params.host =localhost
database.params.username=root1
database.params.password=root
database.params.dbname =zftraining

We use the class to read file Zend_Config_Ini db.ini

 public function indexAction(){
  $filename = CONFIG_PATH . '/db.ini';
  $section = 'infomation';
  $config = new Zend_Config_Ini($filename, $section);
  echo '<pre>';
  print_r($config->toArray());
  echo '</pre>';
  echo '<br>' . $config->webhost;
  echo '<br>' . $config->database->adapter;
  echo '<br>' . $config->database->params->username;
  echo '<br><hr>';
  
 }

Output:

Array
(
    [webhost] => www.example.com
    [database] => Array
        (
            [adapter] => pdo_mysql
            [params] => Array
                (
                    [host] => localhost
                    [username] => root
                    [password] => root
                    [dbname] => zftraining
                )

        )

)

www.example.com
pdo_mysql
root

2.Write ini file

public function writeIniAction(){  

$data = array(
  'global'=>array(
   'smtp'=>array(
    'parameters'=>array(
     'host'  => "smtp.example.com",
     'port'  => "587",
     'username' => "jeky11",
     'password' => "hyd3",
     'security' => "tls",
     ) 
    )   
   ),
    'data'=>array(
     'version' => "1.1"
   )
  );
$config = new Zend_Config_Writer_Ini();
$config->setNestSeparator('::');

$filename = CONFIG_PATH . '/my01.ini';
$objConfig = new Zend_Config($data);
$config->write($filename,$objConfig); 
}

My01.ini output file:

[global]
smtp::parameters::host = "smtp.example.com"
smtp::parameters::port = "587"
smtp::parameters::username = "jeky11"
smtp::parameters::password = "hyd3"
smtp::parameters::security = "tls"

[data]
version = "1.1"

Zend_Translate and Error message

For example: You build a form with Zend_Form, the only one Email address text box is simple and used to determine Zend_Validate_EmailAddress Email is valid:

  $email = new Zend_Form_Element_Text('email', array(
	 'value'   => '',
	 'required' => true,
	 'filter' => 'stringTrim',
	 'label' => 'Email:',
  ));
  $email->addValidator('EmailAddress');

When you run the function, you attempt to enter an invalid email example: 123; á @ 12222, and of course it's an error, a heap of errors like this:

'12222' is no valid hostname for email address '123;á@12222'
'12222' does not match the expected structure for a DNS hostname
'12222' appears to be a local network name but local network names are not allowed
'123;á' can not be matched against dot-atom format
'123;á' can not be matched against quoted-string format
'123;á' is no valid local part for email address '123;á@12222'

But if you want all the messages above a certain language (as Default), why? For example, you want to report in Vietnamese? You will have to use Zend_Translate by way or that. But certainly one thing that you would like to be a headache.

After some research, I found a way that I was very pleased, and in this article I want to share with you. Note that I do on Zend 1:10:

$zTranslate = new Zend_Translate('csv', $langFile, $lang, array('scan' => Zend_Translate::LOCALE_DIRECTORY));
Zend_Validate_Abstract::setDefaultTranslator($zTranslate);

And I wrote in my file vi.csv following language

'%hostname%' is no valid hostname for email address '%value%';
'%hostname%' là một tên host không hợp lệ cho e-mail '%value%'
'%value%' does not match the expected structure for a DNS hostname;
'%value%' không phù hợp với cấu trúc của một tên host DNS
'%value%' appears to be a local network name but local network names are not allowed;
'%value%' dường như là một tên mạng cục bộ nhưng tên mạng nội bộ không được chấp nhận
'%localPart%' can not be matched against dot-atom format;
'%localPart%' không phù hợp với định dạng dot-atom
'%localPart%' can not be matched against quoted-string format;
'%localPart%' không phù hợp với định dạng quoted-string
'%localPart%' is no valid local part for email address '%value%';
'%localPart%' không phải là local part hợp lệ cho email '%value%'

After running the function, the resulting error is as follows:

'12222' là một tên host không hợp lệ cho e-mail '123;á@12222'
'12222' không phù hợp với cấu trúc của một tên host DNS
'12222' dường như là một tên mạng cục bộ nhưng tên mạng nội bộ không được chấp nhận
'123;á' không phù hợp với định dạng dot-atom
'123;á' không phù hợp với định dạng quoted-string
'123;á' không phải là local part hợp lệ cho email '123;á@12222'
