php - LARAVEL: Get an array of scheduled tasks for output in admin dashboard

Question

Using the Laravel task scheduler I have created a number of tasks in Kernel.php

e.g:

$schedule->command('some:command')
    ->daily();

$schedule->command('another:command')
    ->daily();

I would like to display the list of scheduled commands and there frequency (as well as last/next run time, which I can log myself using the before/after functions).

However i'm stuck at the first hurdle. What i'm not sure how to do is get an array of the scheduled tasks that have been defined in Kernel.php

// Example function needs to be created
$tasks = getAllScheduledTasks();

@foreach($tasks as $task)
    <tr>
        <td>{{ $task->name }}</td>
        <td>{{ $task->description }}</td>
    </tr>
@endforeach

Simplified Question: How can I get an array of the scheduled tasks in Laravel?

There's actually no support out of the box for this, unfortunately. What you'll have to do is extend the artisan schedule command and add a list feature. Thankfully there's a simple class you can run:

<?php

namespace AppConsoleCommands;

use IlluminateConsoleCommand;
use IlluminateConsoleSchedulingSchedule;

class ScheduleList extends Command
{
    protected $signature = 'schedule:list';
    protected $description = 'List when scheduled commands are executed.';

    /**
     * @var Schedule
     */
    protected $schedule;

    /**
     * ScheduleList constructor.
     *
     * @param Schedule $schedule
     */
    public function __construct(Schedule $schedule)
    {
        parent::__construct();

        $this->schedule = $schedule;
    }

    /**
     * Execute the console command.
     *
     * @return mixed
     */
    public function handle()
    {
        $events = array_map(function ($event) {
            return [
                'cron' => $event->expression,
                'command' => static::fixupCommand($event->command),
            ];
        }, $this->schedule->events());

        $this->table(
            ['Cron', 'Command'],
            $events
        );
    }

    /**
     * If it's an artisan command, strip off the PHP
     *
     * @param $command
     * @return string
     */
    protected static function fixupCommand($command)
    {
        $parts = explode(' ', $command);
        if (count($parts) > 2 && $parts[1] === "'artisan'") {
            array_shift($parts);
        }

        return implode(' ', $parts);
    }
}

This will provide you with a php artisan schedule:list. Now that's not exactly what you need, but then you can easily get this list from within your Laravel stack by executing:

Artisan::call('schedule:list');

And that will provide you with a list of the schedule commands.

Of course, don't forget to inject the Facade: use IlluminateSupportFacadesArtisan;
