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?我试过
@if(file_exists('/covers/1.jpg')) ok @endif
But it doesn't work (covers
directory is in /public
). I also need to provide a variable ($game->id
) to the function. Unformtunately,
但它不起作用(covers
目录在/public
)。我还需要为$game->id
函数提供一个变量 ( )。不幸的是,
@if(file_exists('/covers/'.$game->id.'.jpg')) ok @endif
doesn't work.
不起作用。

This is working for me, favicon.ico is inside public:
这对我有用,favicon.ico 是公开的:
@if(file_exists('favicon.ico'))
File exists
@else
Could not find file
@endif
So I think you just have to use @if(file_exists('covers/1.jpg'))
所以我认为你只需要使用 @if(file_exists('covers/1.jpg'))

@if (file_exists(public_path('covers/1.jpg')))
Use public_path

使用public_path
获得该文件的物理路径。
