php Lumen：在 Blade 视图中获取 URL 参数

Lumen: get URL parameter in a Blade view

提问by Andrea

I'm trying to get a url parameter from a view file.

我正在尝试从视图文件中获取 url 参数。

I have this url:

我有这个网址：

http://locahost:8000/example?a=10

and a viewfile named example.blade.php.

和视图文件命名example.blade.php。

From the controller I can get the parameter awith $request->input('a').

从控制器我可以得到的参数a用$request->input('a')。

Is there a way to get such parameter from the view (without having to pass it from the controller to the view)?

有没有办法从视图中获取这样的参数（而不必将它从控制器传递到视图）？

This works well:

这很有效：

{{ app('request')->input('a') }}

Where ais the url parameter.

aurl 参数在哪里。

Given your URL:

鉴于您的网址：

http://locahost:8000/example?a=10

The best way that I have found to get the value for 'a' and display it on the page is to use the following:

我发现获取 'a' 值并将其显示在页面上的最佳方法是使用以下内容：

{{ request()->get('a') }}

However, if you want to use it within an if statement, you could use:

但是，如果您想在 if 语句中使用它，您可以使用：

@if( request()->get('a') )
    <script>console.log('hello')</script>
@endif

Hope that helps someone! :)

This works fine for me:

这对我来说很好用：

{{ app('request')->input('a') }}

Ex: to get pagination param on blade view:

例如：在刀片视图上获取分页参数：

{{ app('request')->input('page') }}

You can publicly expose Inputfacade via an alias in config/app.php:

您可以Input通过别名公开外观config/app.php：

'aliases' => [
    ...

    'Input' => Illuminate\Support\Facades\Input::class,
]

And access url $_GETparameter values using the facade directly inside Blade view/template:

并$_GET直接在 Blade 视图/模板中使用外观访问 url参数值：

{{ Input::get('a') }}

As per official 5.8docs:

根据官方5.8文档：

The request() function returns the current request instance or obtains an input item:

request() 函数返回当前请求实例或获取输入项：

$request = request();

$value = request('key', $default);
