README

Breadcrumb builder and controller integration for CodeIgniter 4 projects.

Features

• Reusable breadcrumb builder service
• Ordered breadcrumb items with a single active item
• Named templates for different application areas
• Optional trait for controller integration
• Compatible with CodeIgniter 4.7.2+

Installation

Install the package with Composer:

composer require domprojects/codeigniter4-breadcrumb

Basic Usage

Create and render a breadcrumb manually:

<?php

$breadcrumb = single_service('breadcrumb');

$breadcrumb
    ->add('Home', url_to('home'))
    ->add('Blog', url_to('blog.index'))
    ->add('Article');

echo $breadcrumb->render();

Controller Integration

The package includes a HasBreadcrumb trait to simplify breadcrumb handling in controllers.

<?php

namespace App\Controllers;

use domProjects\CodeIgniterBreadcrumb\Traits\HasBreadcrumb;
use CodeIgniter\Controller;

abstract class BaseController extends Controller
{
    use HasBreadcrumb;
}

Example in a controller:

<?php

$this
    ->breadcrumbRoot('Home', url_to('home'))
    ->breadcrumbController('Blog', 'blog.index')
    ->breadcrumbAppend('Article');

$data['breadcrumb'] = $this->renderBreadcrumb();

Templates

Default config ships with three template names:

• default
• frontend
• backend

Get a configured template in a controller:

<?php

$data['breadcrumb'] = $this->renderBreadcrumb(
    $this->getBreadcrumbTemplate('backend')
);
