ZF Fundamentals June 2019

TODO

  • Q: in the layout there is a reference to $this->inlinescript(); where is it defined?
  • A: This is defined

Class Repository: https://github.com/dbierer/zf-fund-jun-2019

Labs

  • Recommendations

    • Add ini_set('display_errors',1); in /onlinemarket.work/config/development.config.php
    • From /home/vagrant/Zend/workspaces/DefaultWorkspace/onlinemarket.work run composer update after installing the ZF skeleton app. This will get rid of the notices you might see initially.
    • Error log file: sudo tail /var/log/apache2/error.log

  • For Fri 28 Jun 2019

    • Lab: Database Final Lab

  • For Wed 26 Jun 2019

    • Lab: Events
    • Lab: Shared Event Manager
      • To view the error log in the VM: sudo tail /var/log/apache2/error.log

  • For Mon 24 Jun 2019

    • Lab: Forms

  • For Fri 21 Jun 2019

    • Lab: Manipulating Views and Layouts
    • Lab: Create a View Helper

  • For Wed 19 Jun 2019

    • Lab: Creating and Accessing a Service

  • For Mon 17 Jun 2019

    • Lab: Using a Built-in Controller Plugin
    • Lab: Using a Custom Controller Plugin
    • Lab: New Controllers and Factories
      • For creating factories you can use, from the onlinemarket.work project root directory
      • This example creates the PostControllerFactory:
vendor/bin/generate-factory-for-class Market\\Controller\\PostController
  • For Fri 14 Jun 2019
    • Lab: Market Module
    • Lab: Index Controller
    • Lab: Initial View
  • For Wed 12 Jun 2019
    • Lab: fix the Apache vhost definition for onlinemarket.work as shown below
    • Lab: install the Zend Framework skeleton app as described in the lab instructions
      • Recommendation: don't do steps 4 and 5 (so that you'll see the error message associated with missing modules later)
    • Lab: Integrating an Existing Module

Class Discussion

TODO

sudo gedit /etc/apache2/sites-available/onlinemarket.work.conf
  • Add onlinemarket.work after the ServerName directive
  • When done, the config file should look like this:
<VirtualHost *:80>
	ServerName onlinemarket.work
	DocumentRoot /home/vagrant/Zend/workspaces/DefaultWorkspace/onlinemarket.work/public
	<Directory /home/vagrant/Zend/workspaces/DefaultWorkspace/onlinemarket.work/public/>
		Options Indexes FollowSymlinks MultiViews
		AllowOverride All
		Require all granted
	</Directory>
</VirtualHost>
  • Perform a config test to make sure the syntax is correct:
sudo apachectl configtest
  • Restart the web server as follows:
sudo service apache2 start

Errata

  • file:///D:/Repos/ZF-Level-1/Course_Materials/index.html#/9/41: missing the table name: s/be the 1st argument to the TableGateway contructor (see example just below): class UserTableGateway extends TableGateway { ... public function __construct($tableName, Adapter $adapter, AbstractFeature $feature = null,ResultSetInterface $resultSet = null, Sql $sql = null)
  • file:///D:/Repos/ZF-Level-1/Course_Materials/index.html#/9/52: $rowset = $userTableGateway->selectWith($where); s/be $rowset = $userTableGateway->selectWith($select);
  • Database Lab:
    • Some images referenced in the Online Market database are missing from the images folders:
      • copy from onlinemarket.work/public/images folder in this repo
      • also need to restore the listings table from onlinemarket.work/data/sql/listings.sql in this repo to get references to the remaining images
    • Step 4 - Define Adapter Factory: "Build an adapter factory called "Primary" in Model\Adapter\Factory" ... then in step 5 we were asked to a add a new service as follows: 'factories' => [ 'model-primary-adapter' => Adapter\Factory\PrimaryFactory::class],. I think in step 4 the adapter factory should be called PrimaryFactory.
    • Step 5 Add Config Parameters: s/be zfcourse instead of onlinemarket in this config:
'services' => [
    'model-primary-adapter-config' => [
    'driver' => 'PDO',
    'dsn' => 'mysql:hostname=localhost;dbname=onlinemarket',
    'username' => 'vagrant',
    'password' => 'vagrant',
],
  • The class + factory below should include the table name as the first parameter in the constructor:
use Zend\Db\{Adapter\Adapter, Sql\Sql, ResultSet\ResultSetInterface,
    TableGateway\TableGateway, TableGateway\Feature};
class UserTableGateway extends TableGateway {
    const TABLE = 'UserTable';
    protected $adapter;
    protected $feature;
    protected $resultSet;
    protected $sql;
    public function __construct($tableName, Adapter $adapter, AbstractFeature $feature = null,
        ResultSetInterface $resultSet = null, Sql $sql = null) {
        $this->adapter = $adapter;
        $this->feature = $feature;
        $this->resultSet = $resultSet;
        $this->sql = $sql;
    }
}
use User\Table\UserTable;
use Zend\Db\{Sql\Sql, ResultSet\ResultSet, TableGateway\TableGateway};
use Zend\Db\TableGateway\Feature\ {SequenceFeature, EventFeature};
use Interop\Container\ContainerInterface;
use Zend\ServiceManager\Factory\FactoryInterface;
class UserTableGatewayFactory implements FactoryInterface {
    public function __invoke(ContainerInterface $container, $requestedName,
        array $options = null) {
        $adapter = $container->get('model-primary-adapter');
        $features = [new SequenceFeature(), new EventFeature()];
        return new UserTable(UserTable::TABLE, $adapter, $features, new ResultSet, new Sql);
    }
}
  • onlinemarket.complete needs to have public/captcha folder created:
vagrant@zf1-training:~/Zend/workspaces/DefaultWorkspace/onlinemarket.complete$ mkdir public/captcha
vagrant@zf1-training:~/Zend/workspaces/DefaultWorkspace/onlinemarket.complete$ sudo chown vagrant:www-data public/captcha/
vagrant@zf1-training:~/Zend/workspaces/DefaultWorkspace/onlinemarket.complete$ sudo chmod 775 public/captcha
