CAKE 3Introduction to CakePHP 3

CAKE 3CakePHP is a web development framework running on PHP 7 (min. PHP 5.5.9).CakePHP is designed to make common web-development tasks simple, and easy.Follow MVC (Model, View, Controller) formatConventions Over Configuration

Conventions Over Configuration

➤ CakePHP provides a basic organizational structure that covers class names, filenames, database table names, and other conventions. CakePHP provides that you can avoid needless configuration and make a uniform application structure that makes working with various projects simple.

CONVENTIONS OVER CONFIGURATION➤ Table names will be plural (e.g., orders)➤ The name of the primary key field will be id➤ The names of any foreign key fields will be based on

the referenced table name followed by _id (e.g., the foreign key into a customers table would be named customer_id).

LATEST IN CAKE3 IS THE NEW ORM !!!➤ No more array in return.

➤ Cake3 return Entity/Object as return value➤ Validation removed from Model

➤ Now its separated for reusable or more extensible➤ Associations No Longer Defined as Properties

In ArticlesTable.php: class ArticlesTable extends Table { public function initialize(array $config) { $this->belongsTo('Users'); } }

➤ New api function patchEntity, removing not related data from saving$user = $this->Users->patchEntity($user, $this->request->data);

➤ Cake’s ORM would by default retrieve any associated tables when performing a query. As a result, a simple “find all” query could potentially become quite bloated as the underlying SQL would retrieve all data from all associated tables. In version 3, this behavior is no longer the default.

use Cake\ORM\TableRegistry;Controller:$users = TableRegistry::get(‘Users’);

View:<?php foreach ($users as $user): ?> <li class="user"> <?= $this->element('user', ['user' => $user]) ?> </li><?php endforeach; ?>
