Dynamic Menu Builder for Bootstrap 3: Item and Link

In part 1, we prototyped the end product and wrote the main Menu class, which serves as the menu manager - a container to hold all sub-units (items and links). In this part, we’ll build the remainder of the classes and demonstrate the menu builder’s usage.

Item

Represents our menu items as independent objects.

Create a new file called item.php and paste in the following code:

item.php

<?php
class Item {

    protected $manager;
    protected $id;
    protected $pid;
    protected $meta;
    protected $attributes = array();

    public    $link;

    //...
?> 

• $manager stores a reference to the menu manager (Menu object). This makes us able to use menu manager methods within Item context.


• $id stores the item’s id.


• $pid stores item’s parent id if it has one otherwise it’ll be set to null.


• $meta an array for storing extra data with each item.


• $attributes an array of html attributes.


• $link stores an instance of class Link.

__construct(manager, title, url, attributes, pid)

Initializes the attributes.

<?php
public function __construct($manager, $title, $url, $attributes = array(), $pid = 0)
{
    $this->manager     = $manager;
    $this->id          = $this->id();
    $this->pid         = $pid;
    $this->title       = $title;
    $this->attributes  = $attributes;

    // Create an object of type Link
    $this->link        = new Link($title, $url);
}
?> 

add(title, options)

Class Item has an add() method as well (just like the menu manager). In fact this method doesn’t create items on its own. It gets the arguments, a
