php - Determining If a File Exists in Laravel 5

Goal : If the file exist, load the file, else load the default.png.


I've tried

  @if(file_exists(public_path().'/images/photos/account/{{Auth::user()->account_id}}.png'))
    <img src="/images/photos/account/{{Auth::user()->account_id}}.png" alt="">
  @else
    <img src="/images/photos/account/default.png" alt="">
  @endif

Result

It kept load my default image while I'm 100% sure that 1002.png is exist.

How do I properly check if that file is exist ?

Wherever you can, try and reduce the number of if statements. For example, I would do the following:

// 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
<img src="{!! Auth::user()->photo() !!}" alt="">

Makes your template cleaner and uses less code. You can also write a unit test on this method to test your statement as well :-)
