Action App\Http\Controllers\Controller@action not defined
提问by Black
I want to submit a form, but I always get Action App\Http\Controllers\About@show not definedeven though the function showis defined:
我想提交一个表单，但Action App\Http\Controllers\About@show not defined即使show定义了函数，我也总是得到：
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Http\Requests;
class AboutController extends Controller
{
public function create()
{
return view('about.contact');
}
public function show()
{
return view('about.contactshow');
}
}
This is my blade template about\contact.blade.php:
这是我的刀片模板about\contact.blade.php：
{!! Form::open(array('action' => 'About@show', 'method' => 'post')) !!}
{!! Form::label('username','Username',array('id'=>'user','class'=>'')) !!}
{!! Form::text('username','user 1',array('id'=>'user','class'=>'', 'placeholder' => 'user 1')) !!}
{!! Form::submit('Click Me!') !!}
{!! Form::close() !!}
What am I doing wrong?
我究竟做错了什么？

I was able to solve it.
First I had to change 'action' => 'About@show'to 'action' => 'AboutController@show'
我能够解决它。首先，我不得不改变'action' => 'About@show'，以'action' => 'AboutController@show'
Then I had to register all Controller Actions in routes.php:
然后我必须在routes.php 中注册所有控制器操作：
Route::post('contact_show', [
'uses' => 'AboutController@show'
]);
Route::get('contact_create', [
'uses' => 'AboutController@create'
]);

I had the same issue.
我遇到过同样的问题。
The problem was with routes/web.php. I was building my app one step at a time, and because of that I passed a second array to my route using 'only'like this, to make it create the index route only:
问题出在routes/web.php. 我是在一个时间来建立我的应用程序一步，正因为如此我使用过第二阵列到我的路线'only'是这样，使它创建索引航线只：
Route::resource('model', 'ModelController', [
'only' => ['index']
]);
But after creating the 'create' view, I couldn't pass data to storefunction in my controller. I found out because the storefunction requires an explicit route (as mentioned above). So I added it to the 'only'array like this and it worked like a charm:
但是在创建“创建”视图后，我无法将数据传递给store我的控制器中的函数。我发现是因为该store函数需要显式路由（如上所述）。所以我'only'像这样将它添加到数组中，它就像一个魅力：
Route::resource('model', 'ModelController', [
'only' => [
'index',
'create',
'store',
]
]);

You're not calling the good controller!!
你不是在称好控制器！！
{!! Form::open(array('action' => 'AboutController@show', 'method' => 'post')) !!}
instead of:
代替：
{!! Form::open(array('action' => 'About@show', 'method' => 'post')) !!}
It's trying to get the action About@show but you didn't define it like this in your controller!!
它正在尝试获取操作 About@show 但您没有在控制器中这样定义它！！
Hope it helps!
希望能帮助到你！

That's all, because of routes file web.php. Plz check out you routes file
这就是全部，因为 routes 文件web.php。请检查你的路线文件

I had a similar issue but it wasnt my controller name that was wrong (web.php and actual file name were 100% correct). Due to an earlier 'refactor' - it replaced my form action/method. So my form opener looked like so:
我有一个类似的问题，但不是我的控制器名称错误（web.php 和实际文件名 100% 正确）。由于较早的“重构” - 它取代了我的表单操作/方法。所以我的表单开启器看起来像这样：
{!! Form::open(['method'=>'POST', 'action'=>'AdminBankingDetailController', 'class'=>'m-form m-form--state']) !!}
Instead of like so (for the create view/page):
而不是这样（对于创建视图/页面）：
{!! Form::open(['method'=>'POST', 'action'=>'AdminBankingDetailController@store', 'class'=>'m-form m-form--state']) !!}
Make sure it has an @actionon your form.
确保它在您的表单上有 @操作。

When you get this error, it's possible that you entered the wrong spelling in the web.php or another action method. Simply go and check the spelling.
当您收到此错误时，可能是您在 web.php 或其他操作方法中输入了错误的拼写。只需去检查拼写。
