Flow package for WpStarter or Laravel framework that provides a fluent interface for handling workflow and process management.

Configuration

Usage

Create Flow class extends WpStarter\Flow\Flow

namespace App\Flow\Flows;

use WpStarter\Flow\Flow;
use WpStarter\Flow\FlowRequest;
use App\Flow\Flows\OrderFlow;

class LoginFlow extends Flow{
    function handle(FlowRequest $request){
        // TODO: Implement handle() method.
        if($this->state('is_logged_in')){
            $this->redirect(OrderFlow::class);
            return ['success'=>true];
        }else{
            if(Auth::check($request['user'],$request['pass'])){
                $this->state('is_logged_in',true);
                $this->redirect(OrderFlow::class);
                return ['success'=>true];
            }else{
                return ['success'=>false,'message'=>'invalid credentials'];
            }
        }
    }
}

Flow state management

Go to next flow

    $this->redirect(NextFlowClass::class)

Go to previous flow

    $this->back()

Redirect to default flow

    $this->redirectToDefault()

Flow Providers

Create App\Flow\MyFlowProvider extends WpStarter\Flow\Support

class MyFlowProvider extends FlowProvider
{
    public function register()
    {
        $this->flows->register(LoginFlow::class);
        $this->flows->register(OrderFlow::class);
        $this->loadRoutesFrom( __DIR__ . '/routes.php');
    }
}

Add MyFlowProvider to config/flow.php

<?php
return [
    'providers'=>[
        App\Flow\MyFlowProvider::class
    ]
];

Flow Routes

Simple matching

use \WpStarter\Flow\Support\Facades\Route;

//Run login flow when received message /login
Route::match('/login',LoginFlow::class);
//Run order flow when received message /order or /buy
Route::match(['/order','/buy'],OrderFlow::class);

Advanced matching

use \WpStarter\Flow\Support\Facades\Route;

//Run login flow when `secret_login` is 'Abcd1234'
Route::match(function(\WpStarter\Flow\FlowRequest $request){
    if($request->get('secret_login')==='Abcd1234'){
        return true;
    }
},LoginFlow::class);

Auto register route in Flow

Route can be registered automatically by define $route property in Flow class

class LoginFlow extends Flow{
    protected $route='logmein';
}

Above code will register following route

Route::match('logmein',LoginFlow::class);

Run Flow

Create Flow Request

You can create a flow request based on current http request. Normally FlowRequest required to have 2 attributes: id and message. We compare route against message to find matched flow

use WpStarter\Flow\FlowRequest;
$flowRequest=new FlowRequest([
    'id'=>$request['phone_number'],
    'message'=>$request->input('message'),
]);

Run flow in a controller

namespace App\Http\Controllers;
use WpStarter\Flow\FlowManager;
use Illuminate\Http\Request;
class FlowController{
    function index(FlowManager $flowManager, Request $request){
        $flowRequest=new FlowRequest([
            'id'=>Auth::id(),
            'message'=>$request->input('message'),
        ]);
        return $flowManager->run($flowRequest);
    }
}
