Action App\Http\Controllers\KategoriController@store 未定义

Question

我正在使用 Laravel 8，我想尝试使用 Modals 制作输入表单。 这是我的第一次尝试，我不知道我做错了什么，而我认为我已经复制了与教程相同的内容。

错误信息

Action App\Http\Controllers\KategoriController@store 未定义。 （查看：C:\xampp\htdocs\LARAVEL\Workshop\resources\views\back\kategori-produk\tampil.blade.php）

Answer 1

您已使用 GET 提交数据，GET 用于检索数据。您应该使用 POST 代替 GET。查看我的代码并在您的表单和路由中使用它。

Answer 2

首先，将此表单属性操作从 <form action={{ action('App\Http\Controllers\KategoriController@store') }} method="GET"> 更改为<form action={{url('getKategorie') }} method="GET">，然后在路由文件中命名url。我确定这就是你的问题所在。就目前而言，laravel 正在 web.php 文件中查找该操作，但找不到它。因此添加类似Route::get('getKategorie',[KategoriController,'store']); 的内容。您需要注意的另一件事是，您正在使用资源控制器，因此GET http verb 只读取索引方法而不是存储方法。存储方法适用于POST http verb。希望这能回答您的问题。
