Latest Stable Version Total Downloads License SensioLabsInsight

This bundle provides a way to create "dynamic" breadcrumbs in your Symfony applications.

Installation

Composer is the only supported installation method. Run the following to install the latest version from Packagist:

composer require asprega/breadcrumb-bundle

Or, if you prefer, you can require any version in your composer.json:

{
    "require": {
        "asprega/breadcrumb-bundle": "*"
    }
}

NOTE: Until the bundle reaches version 1.0.0 I can't guarantee to follow semantic versioning strictly.

Usage

1. Load bundle

Once installed, load the bundle in your Kernel class:

// ...
class AppKernel extends Kernel
{
    public function registerBundles()
    {
        $bundles = array(
            // ...
            new AndreaSprega\Bundle\BreadcrumbBundle\AndreaSpregaBreadcrumbBundle(),
        );
        // ...
    }
    // ...
}

2. Define breadcrumbs

There are two ways to create a breadcrumb: via code (1) or via annotations (2).

Via code: you can retrieve the breadcrumb builder in your controller and add breadcrumb items:

public function coolStuffAction()
{
    // ...

    $builder = $this->get('asprega.breadcrumb.builder');
    $builder->addItem('home', 'home_route');
    $builder->addItem('$entity.property', 'entity_route');
    $builder->addItem('cool_stuff');

    // ...
}

Via annotations: just use the @Breadcrumb annotation at the class and/or method level. They will be merged (class comes first).

NOTE: The annotation can take either a single item (in the above example it's done at the class level) or multiple items (at the method level).

<?php

use AndreaSprega\Bundle\BreadcrumbBundle\Annotation\Breadcrumb;

/**
 * @Breadcrumb({"label" = "home", "route" = "home_route", "params" = {"p" = "val"}, "translationDomain" = "domain" })
 */
class CoolController extends Controller
{
    /**
     * @Breadcrumb({
     *   { "label" = "$entity.property", "route" = "entity_route" },
     *   { "label" = "cool_stuff" }
     * })
     */
    public function coolStuffAction()
    {
        // ...
    }

3. Render breadcrumb

The last step is to use the following Twig function wherever you want the breadcrumb printed in your template:

asprega_breadcrumb()

Regardless of the way you used to create the breadcrumb, the result will be something like:

Home > Value of entity property > Cool stuff

In which the first two items are anchors and the last one is text only.

How the breadcrumb is generated

Under the hood, this is the business logic involved, for each item, in the breadcrumb generation:

  • label will be the printed text. It can be either:
    • A "static" string (the translator will attempt to translate it by using it as a translation key)
    • A special string, prepended with $. In this case, the breadcrumb label will be extracted from the variable passed to the template. Property paths can be used, e.g.: $variable.property.path
  • route will be used to generate the url for the item anchor (if provided). If not provided, the item will not be clickable.
  • params will be used to generate the url related to the provided route. It's an associative array where each value can be either:
    • A "static" string
    • A "special" string using the format $variable.property.path. The treatment is exactly the same as in "label". This is useful to dynamically retrieve url params (e.g. entity ID) starting from view variables.
  • translationDomain will be used to translate the key provided in the label attribute. If null, the default translation domain will be used. Provide false if you put a non-translatable string in label and you don't want to use it as a translation key.

NOTE: you don't need to pass all the route parameters that are needed by route, as long as these route parameters are already present in the URL for the current request. In other words, if your breadcrumb hierarchical structure somehow "matches" your URL structure.

Example: suppose you have the following routes, with parameters and resulting URLs:

parent_list   |                                       | /parents
parent_view   | { parent_id: 12345 }                  | /parents/12345
children_list | { parent_id: 12345 }                  | /parents/12345/children
child_view    | { parent_id: 12345, child_id: 67890 } | /parents/12345/children/67890
child_edit    | { parent_id: 12345, child_id: 67890 } | /parents/12345/children/67890/edit

If you are in the action for route children_edit and you want to generate a breadcrumb including all the above steps, you will be able to use the following annotation:

/**
 * @Breadcrumb({
 *   { "label" = "parents", "route" = "parent_list" },
 *   { "label" = "$parent.name", "route" = "parent_view" },
 *   { "label" = "children", "route" = "children_list" },
 *   { "label" = "$child.name", "route" = "child_view" },
 *   { "label" = "edit" }
 * })
 */
public function childrenEditAction($parentID, $childrenID)
{
    // ...
}

Note how you don't have to provide the route parameters (since the current request already has them all). It would work the same if you build it via code instead.

Override breadcrumb template

The bundle default template for rendering breadcrumb can be overridden by adding the following lines to the config.yml of your application:

asprega_breadcrumb:
    template: YourBundle::breadcrumb.html.twig

If you intend to do this, it's recommended to copy Resources/views/breadcrumb.html.twig to your bundle and customize it. However, in your template you'll just have to iterate over the items variable to render your custom breadcrumb.
