laravel - 将参数传递给组件时出错

Question

在这里阅读如何制作组件 https://laravel.com/docs/7.x/blade#components在我的 Laravel Framework 7.6.2 应用程序中出现错误:

Unresolvable dependency resolving [Parameter #0 [ <required> $is_auto_hide ]] in class App\View\Components\AppBackendHeader (View:

我在组件 app/View/Components/AppBackendHeader.php 中定义的第一个变量:

<?php

namespace App\View\Components;

use Illuminate\View\Component;

class AppBackendHeader extends Component
{

    public $is_auto_hide;

    public $message;
    public function __construct($is_auto_hide, $message)
    {
        $this->is_auto_hide = $is_auto_hide;
        $this->message = $message;
    }
    public function render()
    {
        return view('components.app-backend-header');
    }
}


calling this component from blade page : 
        <x-app-backend-header is_auto_hide="true" message="message 1234" />


In app/Providers/AppServiceProvider.php I added line :

    public function boot()
    {
        Blade::component('app-backend-header', AppBackendHeader::class);
...

调用模板我传递了 is_auto_hide 参数，它看起来不像拼写错误......

我尝试运行命令:

$ composer dump-autoload 
$ php artisan view:clear
$ php artisan config:cache

这并没有帮助...有什么问题？

谢谢!

根据documentation :

Component constructor arguments should be specified using camelCase, while kebab-case should be used when referencing the argument names in your HTML attributes.

这意味着您需要:

public function __construct($isAutoHide, $message)
{
    $this->is_auto_hide = $isAutoHide;
    $this->message = $message;
}

你应该这样调用它:

 <x-app-backend-header is-auto-hide="true" message="message 1234" />
