How to include a blade template only if it exists?
提问by Cedric
How to @include a blade template onlyif it exists ? I could do something like that :
仅当刀片模板存在时，如何@include 刀片模板？我可以做这样的事情：
@if (File::exists('great/path/to/blade/template.blade.php'))
@include('path.to.blade.template')
@endif
But that really isn't elegant and efficient.
但这确实不优雅和高效。
I could include it without if statements, and catch & hide errors if the file isn't here, but that is a little dirty, if not barbaric.
我可以在没有 if 语句的情况下包含它，如果文件不在这里，则捕获并隐藏错误，但这有点脏，如果不是野蛮的话。
What would be great is something like that :
什么会很棒是这样的：
@includeifexists('path.to.blade.template')
(pseudo code, but this blade command does not exist)
（伪代码，但是这个刀片命令不存在）

Had a similar issue. Turns out there is an @includeIfblade directive for this purpose.
有一个类似的问题。事实证明@includeIf，为此目的有一个刀片指令。
Simply do @includeIf('path.to.blade.template')
简单地做 @includeIf('path.to.blade.template')

You can use View::exists()to check if a view exists or not.
您可以View::exists()用来检查视图是否存在。
@if(View::exists('path.to.view'))
@include('path.to.view')
@endif
Or you can extend blade and add new directive
或者您可以扩展刀片并添加新指令
Blade::directive('includeIfExists', function($view) {
});

When needed in a Controller (from this documentation):
在控制器中需要时（来自本文档）：
Determining If A View Exists If you need to determine if a view exists, you may use the exists method after calling the view helper with no arguments. This method will return true if the view exists on disk:
确定一个视图是否存在如果你需要确定一个视图是否存在，你可以在调用不带参数的视图助手后使用exists方法。如果视图存在于磁盘上，此方法将返回 true：
use Illuminate\Support\Facades\View;
use Illuminate\Support\Facades\View;
if (View::exists('emails.customer')) {
\
}
