Provides centralized storing of file attachment.

How to use?

1. Install composer require rollswan/centralized-attachment
2. Migrate attachments table by running php artisan migrate
3. Use WithAttachments trait in your controller

Example:

namespace App\Http\Controllers;

use Rollswan\CentralizedAttachment\Traits\WithAttachments;

class ArticleController extends Controller
{
    use WithAttachments;
}

1. Use storeAttachment() method in controller,

Example:

$this->storeAttachment(
    $file, // This is for the attach file or generated file
    $folderName, // Attach file will store in the /storage/app/<folder-name> (for s3, bucket-name/<folder-name>)
    'App\Models\ModelName', // Owner Model
    $ownerModel, // Owner Model ID
    $generatedFileExtName, // Optional Param, To check whether the attach file is coming from file upload or generated file. Note: Set this file extension name argument if the attach file is generated/created file
    $disk // Optional Param, The default value is local disk. Simply change the filesystem disk if you wish to switch between the configured storage options
);

namespace App\Http\Controllers;

use Rollswan\CentralizedAttachment\Models\Attachment;
use Rollswan\CentralizedAttachment\Traits\WithAttachments;

class ArticleController extends Controller
{
    use WithAttachments;

    /**
     * Creates a new article.
     *
     * @param  CreateArticleRequest $request
     * @return \Illuminate\Http\RedirectResponse
     */
    public function create(CreateArticleRequest $request)
    {
        // Create the article
        $article = Article::create($request->except('_token'));

        // Process attachments, if any
        if (!empty($request->attachments)) {
            $this->storeArticleAttachments($article->id, $request->attachments);
        }

        session()->flash('success', "Article has been successfully created.");
        return back();
    }

    /**
     * Store article attachments.
     *
     * @param integer $articleId
     * @param \Illuminate\Http\UploadedFile $attachments
     */
    private function storeArticleAttachments($articleId, $attachments)
    {
        foreach ($request->attachments as $attachment) {
            $this->storeAttachment(
                $attachment,
                'articles',
                'App\Models\Article',
                $articleId
            );
        }
    }
}    

1. Use Attachment model in controller

Example:

namespace App\Http\Controllers;

use Rollswan\CentralizedAttachment\Models\Attachment;
use Rollswan\CentralizedAttachment\Traits\WithAttachments;

class ArticleController extends Controller
{
    use WithAttachments;

    /**
     * View attachment.
     *
     * @param  string $uuid
     * @return \Symfony\Component\HttpFoundation\BinaryFileResponse
     */
    public function viewAttachment($uuid)
    {
        $attachment = Attachment::find($uuid);
        if (!$attachment) {
            abort(404);
        }

        return $this->streamAttachment($attachment, 'application/pdf');
    }
}

1. Use deleteAttachment() method in controller

Example:

namespace App\Http\Controllers;

use Rollswan\CentralizedAttachment\Models\Attachment;
use Rollswan\CentralizedAttachment\Traits\WithAttachments;

class ArticleController extends Controller
{
    /**
     * Delete article attachments.
     *
     * @param integer $articleId
     */
    private function deleteArticleAttachment($articleId)
    {
        // Get the article attachments
        $attachments = Attachment::where('owner_model', 'App\Models\Article')
            ->where('owner_id', $articleId)
            ->get();

        foreach ($attachments as $attachment) {
            $this->deleteAttachment($attachment);
        }
    }
}
