Upload

File uploads library with validation uses PSR-7 UploadedFileInterface and League\Flysystem as a file storage library

Installation

Requires PHP 8.2 or later.

Install via Composer:

composer require enjoys/upload:^4.0

Basic Usage

use Psr\Http\Message\ServerRequestInterface;

/** @var Psr\Http\Message\UploadedFileInterface $uploadedFile */
/** @var League\Flysystem\Filesystem $filesystem */

$file = new Enjoys\Upload\UploadProcessing($uploadedFile, $filesystem);

try {
    $file->upload();       
} catch (\Exception $e) {
    // Handle exception
}

Validation Rules

The library includes 3 built-in validation rules. You can also create custom rules by implementing Enjoys\Upload\RuleInterface.

Available rules:

• Extension (Enjoys\Upload\Rule\Extension) — Validates file extensions
• Size (Enjoys\Upload\Rule\Size) — Validates file size
• MediaType (Enjoys\Upload\Rule\MediaType) — Validates MIME types

Adding Validation Rules

/** @var Enjoys\Upload\UploadProcessing $file */
/** @var Enjoys\Upload\RuleInterface $rule */

$file->addRule($rule); // Add before calling upload()
$file->upload();

Extension Rule

Case-insensitive extension validation:

$rule = new Enjoys\Upload\Rule\Extension();
$rule->allow('png'); // Single extension
$rule->allow('png, jpg'); // Comma-separated
$rule->allow(['png', 'jpg']); // Array of extensions

Size Rule

$rule = new Enjoys\Upload\Rule\Size();
$rule->setMaxSize(10 * 1024 * 1024) // 10MB
     ->setMinSize(1 * 1024 * 1024); // 1MB (values in bytes)

MediaType Rule

$rule = new Enjoys\Upload\Rule\MediaType();
$rule->allow('image/*') // All image types
     ->allow('application/pdf') // PDF files
     ->allow('*/vnd.openxmlformats-officedocument.*'); // Office documents
$rule->allow('*'); // All types

Event System

The library provides PSR-14 compatible events:

Available Events:

• BeforeValidationEvent - Dispatched before validation starts
• BeforeUploadEvent - Dispatched after validation, before file upload
• AfterUploadEvent - Dispatched after successful file upload
• UploadErrorEvent - Dispatched when any error occurs

Usage Example:

use Enjoys\Upload\Event\AfterUploadEvent;
use Psr\EventDispatcher\EventDispatcherInterface;

/** @var EventDispatcherInterface $dispatcher */

// Initialize with event dispatcher
$upload = new UploadProcessing($uploadedFile, $filesystem, $dispatcher);

// Add event listener
$dispatcher->addListener(
    AfterUploadEvent::class,
    function (AfterUploadEvent $event) {
        logger()->info("File uploaded to: " . $event->uploadProcessing->getTargetPath());
    }
);

$upload->upload();

Event Propagation:

All events implement StoppableEventInterface. To stop further processing:

$dispatcher->addListener(
    BeforeUploadEvent::class,
    function (BeforeUploadEvent $event) {
        if ($shouldStop) {
            $event->stopPropagation(); // Stops other listeners
        }
    }
);
