Hi,

I would like to build myself a OOP based guestbook (with admin section if that's possible) to reuse easy in my websites... (I was thinking about using OOP to make the reuse of my guestbook easier).

In this way I want to create insight on how to program correctly in OOP in PHP.

Anyone care to help me on this? :)

By now I have written a class called Post (Post.class.php file in model folder)

My structure is:
model
Post.class.php
view
index.php
controller

Here's the Post class that represents a post in the guestbook.

<?php
/*
 * Een post from a guestbook has an:
 * - Title
 * - Content
 * - Date
 * - Emailadres
 */
class Post{
	
	//Post attributes
	private $id;
	private $title;
	private $date;
	private $email;
	private $content;
	
	//Post constructor
	public function __construct($id="", $title="", $date="", $email="", $content=""){
		$this->setId($id);
		$this->setTitle($title);
		$this->setDate($date);
		$this->setEmail($email);
		$this->setContent($content);
	}
	
	//Post setters
	public function setId($id){
		if(is_integer($id)){
			$this->id = $id;
		}else{
			throw new Exception("Je hebt geen geldige id opgegeven");
		}
	}
	
	public function setTitle($title){
		if(strlen($title)>0){
			$this->title = $title;
		}else{
			throw new Exception("Je moet een titel invullen");
		}
	}
	
	public function setDate($date){
		$this->date = $date;
	}
	
	public function setEmail($email){
		$this->email = $email;
	}
	
	public function setContent($content){
		if(strlen($content)>3){
			$this->content = $content;			
		}else{
			throw new Exception("Je bericht is te kort.");
		}
	}
	
	//Post getters
	public function getTitle(){
		return $this->title;
	}
	
	public function getDate(){
		return $this->date;
	}
	
	public function getEmail(){
		return $this->email;
	}
	
	public function getContent(){
		return $this->content;
	}
	
	
}
?>

I've added this class Post_store with a funciton to get all the posts from the guestbook (also in de model folder)

Here it is:

<?php
class Post_store{
	
	public function __construct(){
		mysql_connect("localhost", "root", "root") or die("Kon niet verbinden met de server");
		mysql_select_db("guestbook") or die("Kon niet verbinden met de database.");
	}
	
	
	//This function returns an array of all the posts.
	public function showAll(){
		$posts = array();
		$result = mysql_query("SELECT * FROM guestbook") or die("Fout in ophaal query");
		if(mysql_num_rows($result)>0){
			while($row = mysql_fetch_array($result)){
				foreach($row as $post_data){
					$posts[] = new Post($post_data[0], $post_data[1], $post_data[2], $post_data[3], $post_data[4]);
				}
			}
		}
		return $posts;
	}
	
}
?>
