The master branch will always contain the latest stable version. If you wish to check older versions or newer ones currently under development, please switch to the relevant branch/tag.

Getting Started

Requirements

To use this component, you need at least:

• Composer
• PHP >= 5.5
• Phalcon Framework release extension enabled >= 2.x < 4.x

NOTE: Support for legacy PHP versions (down to 7.0) is provided on a best-effort basis.

Installing

$ composer require sergeyklay/breadcrumbs

Define your breadcrumbs

We recommend registering it with your application's services for even easier use:

<?php

use Phalcon\Breadcrumbs;

// Initialize the Breadcrumbs component.
$di->setShared('breadcrumbs', function () {
    return new Breadcrumbs;
});

Adding a crumb with a link:

<?php

$this->breadcrumbs->add('Home', '/');

Adding a crumb without a link (normally the last one):

<?php

$this->breadcrumbs->add('User', null, ['linked' => false]);

Output crumbs:

Php Engine

<ol class="breadcrumb">
    <?php $this->breadcrumbs->output(); ?>
</ol>

Volt Engine

<ol class="breadcrumb">
  {{ breadcrumbs.output() }}
</ol>

Change crumb separator:

<?php

$this->breadcrumbs->setSeparator(' &raquo; ');

Make The last element is always not a link:

<?php

$this->breadcrumbs->setLastNotLinked(true);

Delete a crumb (by url):

<?php

$this->breadcrumbs->remove('/admin/user/create');

// remove a crumb without an url
$this->breadcrumbs->remove(null);

Update an existing crumb:

<?php

$this->breadcrumbs->update('/admin/user/remove', ['label' => '<strong class="red">Remove</strong>']);

Count crumbs:

<?php

$this->breadcrumbs->count();

Sets rendering template:

<?php

$this->breadcrumbs->setTemplate(
    '<li><a href="{{link}}">{{icon}}{{label}}</a></li>', // linked
    '<li class="active">{{icon}}{{label}}</li>',         // not linked
    '<i class="fa fa-dashboard"></i>'                    // first icon
);

Multi-language support:

<?php

use Phalcon\Translate\Adapter\NativeArray as Translator;
use Phalcon\Breadcrumbs;

$messages = [
    'crumb-home'     => 'Home',
    'crumb-user'     => 'User',
    'crumb-settings' => 'Settings',
    'crumb-profile'  => 'Profile',
];

// Initialize the Translate adapter.
$di->setShared('translate', function () use ($messages) {
    return new Translator(['content' => $messages]);
});

// Initialize the Breadcrumbs component.
$di->setShared('breadcrumbs', function () {
    return new Breadcrumbs;
});

Errors logging:

<?php

use Phalcon\Logger\Formatter\Line as FormatterLine;
use Phalcon\Logger\Adapter\File as FileLogger;
use Phalcon\Breadcrumbs;

/**
 * Initialize the Logger.
 *
 * @var $config array
 * @var $di \Phalcon\Di
 */
$di->setShared('logger', function ($filename = null, $format = null) use ($config) {
    $formatter = new FormatterLine($config->get('logger')->format, $config->get('logger')->date);
    $logger = new FileLogger($config->get('logger')->path . $config->get('logger')->filename);

    $logger->setFormatter($formatter);
    $logger->setLogLevel($config->get('logger')->logLevel);

    return $logger;
});

// Initialize the Breadcrumbs component.
$di->setShared('breadcrumbs', function () {
    return new Breadcrumbs;
});

Events

<?php

use Phalcon\Breadcrumbs;
use Phalcon\Events\Manager as EventsManager;

// Initialize the Events Manager.
$di->setShared('eventsManager', function () {
    return new EventsManager;
});

// Initialize the Breadcrumbs component.
$di->setShared('breadcrumbs', function () use ($di) {
    $manager = $di->getShared('eventsManager');
    $manager->attach('breadcrumbs', function ($event, $connection) {
        // We stop the event if it is cancelable
        if ($event->isCancelable()) {
            // Stop the event, so other listeners will not be notified about this
            $event->stop();
        }

        // Receiving the data from the event context
        print_r($event->getData());
    });

    $breadcrumbs = new Breadcrumbs;
    $breadcrumbs->setEventsManager($manager);

    return $breadcrumbs;
