使用 laravel 5.2 调用未定义函数 Form()

Question

当我进入我的视图时，出现以下错误：

FatalErrorException in 9edd5e400844b5418c6227c302e89f04657fb615.php line 3: Call to undefined function Form()

我的查看文件：

{!!Form::open(array('url'=>'resetpwd','method'=>'PUT')) ;!!}
 <p>{!!Form(password('password'));!!}</p>
 {!!$errors->first('password');!!}
 {!!Form::hidden('code',$code);!!}
 <p> {!!Form::submit('Reset Passsword');!!} </p>
 {!!Form::close();!!}
 {!!$errors->first('reseterror');!!}

我假设您已经安装了 Laravel Recepie. You do not declare Form::password() method correctly.Edit your code with below changes hope it will be helped you.See 如何在 Laravel Recepie 中使用此方法。
将 {!!Form(password('password'));!!} 更改为 {!!Form::password('password');!!}

表单不是核心组件的一部分，因此您需要将其添加到 laravel。为此，您需要编辑 laravel 主目录中的 composer.json 文件。更改此行

 "require": {
        "php": ">=5.5.9",
        "laravel/framework": "5.2.*"
    },

到

 "require": {
        "php": ">=5.5.9",
        "laravel/framework": "5.2.*",
        "laravelcollective/html": "5.2.*"
    },

然后在您的终端中运行 composer update。它将添加所有包含表单的集合。

接下来，您必须将新提供者添加到 config/app.php.

的提供者数组中

您会在 app.php

中找到它

 'providers' => [

        /*
         * Laravel Framework Service Providers...
         */
        Illuminate\Auth\AuthServiceProvider::class,
        Illuminate\Broadcasting\BroadcastServiceProvider::class,
        Illuminate\Bus\BusServiceProvider::class,
        Illuminate\Cache\CacheServiceProvider::class,
        Illuminate\Foundation\Providers\ConsoleSupportServiceProvider::class,
        ....................

需要加行Collective\Html\HtmlServiceProvider::class, 所以将供应商更改为

Illuminate\Auth\AuthServiceProvider::class,
        Illuminate\Broadcasting\BroadcastServiceProvider::class,
        Illuminate\Bus\BusServiceProvider::class,
        Illuminate\Cache\CacheServiceProvider::class,
        Illuminate\Foundation\Providers\ConsoleSupportServiceProvider::class,
        Collective\Html\HtmlServiceProvider::class, ....

最后一步是将两个 class 别名添加到 config/app 的别名数组。php

 'aliases' => [

        'App' => Illuminate\Support\Facades\App::class,
        'Artisan' => Illuminate\Support\Facades\Artisan::class,
        'Auth' => Illuminate\Support\Facades\Auth::class,...

ADD 额外的两个classes FORM,HTML那里

 'App' => Illuminate\Support\Facades\App::class,
    'Artisan' => Illuminate\Support\Facades\Artisan::class,
    'Auth' => Illuminate\Support\Facades\Auth::class,
    'Form' => Collective\Html\FormFacade::class,
    'Html' => Collective\Html\HtmlFacade::class,...

现在您可以使用laravel中的表格了。
