Important note

This tool brings the power of Laravel's Illuminate packages to your WordPress project. However, it's important to know that it doesn't include every single feature from Laravel. The examples below will give you a good idea of what's possible, but they don't cover everything.

As a specific example, waffle_cache()->flexible('...') will not work because Waffle does not yet support Laravel's Deferred functionality. If you plan to explore addition features, please test first.

We hope to add more features as the community's needs grow.

Installation

Install the package via composer.

composer require boxybird/waffle

Boot Waffle within a theme or plugin.

require_once __DIR__.'/vendor/autoload.php';

BoxyBird\Waffle\Waffle::boot();

// Notes on setOptions(): 
// Both 'timeout' and 'maxTime' work hand in hand as exceptions are thrown if either exceeds server timeout
// Defined Job class properties will override global setOptions() values

// Notes on workers:
// Workers use WP-Cron to run in the background. The interval is 60 seconds
// Only a single worker can be run at a time. The last declared worker will be the one that runs
waffle_worker()->work(); // This will not run
waffle_worker(['my_custom_queue', 'default'])->work(); // This will run
