确定Laravel 5中是否存在文件

目标:如果文件存在,请加载文件,否则加载default.png.

我试过了

  @if(file_exists(public_path().'/images/photos/account/{{Auth::user()->account_id}}.png'))
    
  @else
    
  @endif

结果

它保持加载我的默认图像,而我100%确定1002.png存在.

如何正确检查该文件是否存在？

无论您在哪里,都可以尝试减少if语句数量.例如,我会做以下事情:

// User Model
public function photo()
{
    if (file_exists( public_path() . '/images/photos/account/' . $this->account_id . '.png')) {
        return '/images/photos/account/' . $this->account_id .'.png';
    } else {
        return '/images/photos/account/default.png';
    }     
}

// Blade Template

$result = File::exists($myfile);

      @if(file_exists( public_path().'/images/photos/account/'.Auth::user()->account_id.'.png' ))
        
      @else
        
      @endif

$exists = Storage::disk('s3')->exists('file.jpg');

$file = ($exists) ? Storage::disk('s3')->get('file.jpg') : 
         Storage::disk('s3')->get('default.jpg');
