Extremely simple and easy example to understand MVC pattern in PHP application (bookstore in this example), with Bootstrap, PDO, jquery and CRUD model

Example of MVC in php, with Bootstrap, PDO, jquery and CRUD by TecnoEstrategia

Introduction

This is a example of MVC (Model View Controller architecture pattern) in php whit PDO (MySql) bootstrap and jquery.

Also, this example is oriented with interfaces, namespaces, etc to explain a concept of CRUD aplications in modern php.

In the best way, that be used the most PSR fix, well as far as possible (this not a example of standard).

Installation

You can found the schema of DB in [files/sql/mvctest.sql] In config/config.inc.php you can set some constants like:

 database
 host_db
 charset_db
 database_user
 database_pass

Also you can set:

Language
Time zone
Name of cookie

The file with constants for english language = lang/en.php you can use the schema (constants) to set another language, for example to set spanish language:

• Create new file lang/es.php
• Copy inside the content of lang/en.php
• Modify the constants like this define("TITLE", "your translation");

Also, in the config file you find the autoload

@TODO = Implements a spl_autoload

That's all

Usage

First, the front controller

We set the front controller in the index.php file

Well, the var c = controller in the url, sets the controller like this:

yoursite/index.php?c=YOU_CONTROLLER yoursite/index.php?c=ANOTHER_CONTROLLER yoursite/index.php?c=AND_ANOTHER_CONTROLLER

All controllers in:

 entity/controller

Example of controllers and respective urls

Controller file	URL to invoke
entity/controller/index.php	yoursite/index.php?c=index
entity/controller/author.php	yoursite/index.php?c=author
entity/controller/book.php	yoursite/index.php?c=book

Second, actions for controller

The next var a = action, set the methods for the controller, for example yoursite/index.php?c=YOU_CONTROLLER&a=YOUR_ACTION

Set YOUR_ACTION in the entity/controller/file

for example,if you want see the front controller for book type this url yoursite/index.php?c=book and if you want set some actions you can use yoursite/index.php?c=booka=CreateBook or yoursite/index.php?c=booka=DeleteBook etc.

Example of controllers and action and respective urls

Controller file	URL to invoke
entity/controller/index.php	yoursite/index.php?c=index&a=deletepage
entity/controller/author.php	yoursite/index.php?c=author&a=listallauthor
entity/controller/book.php	yoursite/index.php?c=book&a=createbook

Ok, this actions are methods of NAME_OF_CONTROLLER Controller class.

Example for controller file

 require_once 'entity/model/book.php'

 class BookController {
	private $model;

	public function __CONSTRUCT(){
        $this->model = new Book();
    }

  public function OneBook()  {
		/* Code for call actions, actions sets in the model files */
		/* you can inovke your views */
		/* Example */
		$ShowData = $this->model->ShowAllBooks();
		require_once 'dir/views/myview.php';

  }

  public function DeleteBook()  {
		/* Code for call actions, actions sets in the model files */
  }

  public function AnotherAction(){
  		/* Code for call actions, actions sets in the model files */

  }

Third, the models

In the model file you can set the actions for the controller, all the models in:

 entity/model

Example for model file

 class index {
	public function ShowAllBooks(){
  		$query = "select * from books";
  		$stmt = $this->pdo->prepare($query);
        $stmt->execute(array($data));
        return $stmt->fetchAll(PDO::FETCH_OBJ);
  }

  public function DeleteBook($id){
        $sql = "DELETE FROM books WHERE books.id_book = $id";
        $this->pdo->prepare($sql)->execute();
    }

At last, the views

You can find the views in entity/views directory.

Example for view file

 <div class="showtitle">
    <h2>Title: <?php echo $ShowData->title ?></h2>
</div>
