如果Laravel的Blade模板检查文件是否存在 [英] Check for file existence if Laravel's Blade template

问题描述

我有一个简单的问题-如何检查Laravel的Blade模板中是否存在文件? 我尝试过

I have a simple problem - how can I check if file exists in Laravel's Blade template? I tried

@if(file_exists('/covers/1.jpg')) ok @endif

但是它不起作用(covers目录位于/public中).我还需要为该函数提供一个变量($game->id).不幸的是

But it doesn't work (covers directory is in /public). I also need to provide a variable ($game->id) to the function. Unformtunately,

@if(file_exists('/covers/'.$game->id.'.jpg')) ok @endif

不起作用.

推荐答案

这对我有用，favicon.ico在公共内部:

This is working for me, favicon.ico is inside public:

@if(file_exists('favicon.ico')) 
  File exists
@else
  Could not find file
@endif

所以我认为您只需要使用@if(file_exists('covers/1.jpg'))

So I think you just have to use @if(file_exists('covers/1.jpg'))
