README
Use the Symfony Workflow component in Laravel
Installation
composer require hpez/laravel-workflow
For laravel <= 5.4
Add a ServiceProvider to your providers array in config/app.php
:
<?php 'providers' => [ ... Hpez\LaravelWorkflow\WorkflowServiceProvider::class, ]
Add the Workflow
facade to your facades array:
<?php ... 'Workflow' => Hpez\LaravelWorkflow\Facades\WorkflowFacade::class,
Configuration
Publish the config file
php artisan vendor:publish --provider="Hpez\LaravelWorkflow\WorkflowServiceProvider"
Configure your workflow in config/workflow.php
<?php return [ 'straight' => [ 'type' => 'workflow', // or 'state_machine' 'marking_store' => [ 'type' => 'multiple_state', 'arguments' => ['currentPlace'] ], 'supports' => ['App\BlogPost'], 'places' => ['draft', 'review', 'rejected', 'published'], 'transitions' => [ 'to_review' => [ 'from' => 'draft', 'to' => 'review' ], 'publish' => [ 'from' => 'review', 'to' => 'published' ], 'reject' => [ 'from' => 'review', 'to' => 'rejected' ] ], ] ];
Use the WorkflowTrait
inside supported classes
<?php namespace App; use Illuminate\Database\Eloquent\Model; use Hpez\LaravelWorkflow\Traits\WorkflowTrait; class BlogPost extends Model { use WorkflowTrait; }
Usage
<?php use App\BlogPost; use Workflow; $post = BlogPost::find(1); $workflow = Workflow::get($post); // if more than one workflow is defined for the BlogPost class $workflow = Workflow::get($post, $workflowName); $workflow->can($post, 'publish'); // False $workflow->can($post, 'to_review'); // True $transitions = $workflow->getEnabledTransitions($post); // Apply a transition $workflow->apply($post, 'to_review'); $post->save(); // Don't forget to persist the state // Using the WorkflowTrait $post->workflow_can('publish'); // True $post->workflow_can('to_review'); // False // Get the post transitions foreach ($post->workflow_transitions() as $transition) { echo $transition->getName(); } // if more than one workflow is defined for the BlogPost class foreach ($post->workflow_transitions($workflowName) as $transition) { echo $transition->getName(); } // Apply a transition $post->workflow_apply('publish'); $post->save();
Use the events
This package provides a list of events fired during a transition
Hpez\LaravelWorkflow\Events\Guard Hpez\LaravelWorkflow\Events\Leave Hpez\LaravelWorkflow\Events\Transition Hpez\LaravelWorkflow\Events\Enter Hpez\LaravelWorkflow\Events\Entered
You can subscribe to an event
<?php namespace App\Listeners; use Hpez\LaravelWorkflow\Events\GuardEvent; class BlogPostWorkflowSubscriber { /** * Handle workflow guard events. */ public function onGuard(GuardEvent $event) { /** Symfony\Component\Workflow\Event\GuardEvent */ $originalEvent = $event->getOriginalEvent(); /** @var App\BlogPost $post */ $post = $originalEvent->getSubject(); $title = $post->title; if (empty($title)) { // Posts with no title should not be allowed $originalEvent->setBlocked(true); } } /** * Handle workflow leave event. */ public function onLeave($event) {} /** * Handle workflow transition event. */ public function onTransition($event) {} /** * Handle workflow enter event. */ public function onEnter($event) {} /** * Handle workflow entered event. */ public function onEntered($event) {} /** * Register the listeners for the subscriber. * * @param Illuminate\Events\Dispatcher $events */ public function subscribe($events) { $events->listen( 'Hpez\LaravelWorkflow\Events\GuardEvent', 'App\Listeners\BlogPostWorkflowSubscriber@onGuard' ); $events->listen( 'Hpez\LaravelWorkflow\Events\LeaveEvent', 'App\Listeners\BlogPostWorkflowSubscriber@onLeave' ); $events->listen( 'Hpez\LaravelWorkflow\Events\TransitionEvent', 'App\Listeners\BlogPostWorkflowSubscriber@onTransition' ); $events->listen( 'Hpez\LaravelWorkflow\Events\EnterEvent', 'App\Listeners\BlogPostWorkflowSubscriber@onEnter' ); $events->listen( 'Hpez\LaravelWorkflow\Events\EnteredEvent', 'App\Listeners\BlogPostWorkflowSubscriber@onEntered' ); } }
Dump Workflows
Symfony workflow uses GraphvizDumper to create the workflow image. You may need to install the dot
command of Graphviz
php artisan workflow:dump workflow_name --class App\\BlogPost
You can change the image format with the --format
option. By default the format is png.
php artisan workflow:dump workflow_name --format=jpg
