【メモ】intervention/imageを使って画像のリサイズとストレージへの保存

Last updated at Posted at 2021-04-11

バージョン

  • PHP7.3
  • Laravel7.30

ライブラリのインストール

$ composer require intervention/image

実装

プロバイダ登録

config/app.php

'providers' => [
  // 中略
  App\Providers\RouteServiceProvider::class,
  Illuminate\View\ViewServiceProvider::class,  // 追加
],

'aliases' => [
  'InterventionImage' => Intervention\Image\Facades\Image::class,
]
/var/www/laravel
$ php artisan config:cache

保存

横幅 500px で保存してみる


public function store(Request $request)
{
  if (Storage::missing('public/resized')) {
    Storage::makeDirectory('public/resized');
  }

  $file = $request->file('test_image');
  $response = $this->putResizedFile($file, storage_path('app/public/resized/test_image.' . $file->extension()), 500);

  return response($response, 200);
}

/**
  * @param $fileData = リソース
  * @param string $tempPath = 保存先
  * @param int $width サムネイルのサイズ
  * @return \Intervention\Image\Image
  */
protected function putResizedFile($fileData, $tempPath, int $width)
{
  return \InterventionImage::make($fileData)->resize($width, null, function ($constraint) {
    $constraint->aspectRatio();
  })->save($tempPath);
}

削除

Storage ファサードを使う

Storage::delete('public/resized/test_image.png');

注意点

storage/app/public直下にresizedディレクトリがない場合、勝手にディレクトリを作るようなことはなくエラーが出るため**Storage::missing()**でチェックしている。

storage/laravel.log
"Can't write image data to path (/var/www/laravel/storage/app/public/resized/test_image.png)"

この点、Storage::put('public/resized/test_image.png')の場合は勝手に作ってくれることと比較。
