Laravel 4 passing parameters to Controller from Form in View
提问by user2525589
I want to save data to the database by clicking on a button in a view file.
我想通过单击视图文件中的按钮将数据保存到数据库中。
I would like to achieve this by calling a method in my controller via POST. It works but I have to pass some variables/parameters ( without having inputfields ) to the controller and that doesn't work.
我想通过 POST 在我的控制器中调用一个方法来实现这一点。它有效，但我必须将一些变量/参数（没有 inputfields ）传递给控制器，但这是行不通的。
this is my controller:
这是我的控制器：
class CouplesController extends BaseController {
public function postCreate($var1)
{
Couple::create(array(
'name'=>'test',
'id1'=>$var1
));
return Redirect::to('couples')
->with('message','Your couple was created successfully!');
}
}
and this is my view:
这是我的观点：
{{ Form::open(array('action' => 'CouplesController@postCreate', $var1->'hello')) }}
<p>{{ Form::submit('Create') }}</p>
{{ Form::close() }}
probably I'm doing this completely wrong. I just don't know how to do this.
可能我这样做完全错误。我只是不知道该怎么做。
btw it doesn't have to be the POST method.
顺便说一句，它不一定是 POST 方法。

You are really close, within your view:
在你看来，你真的很接近：
{{ Form::open(array('action' => 'CouplesController@postCreate', 'hello')) }}
<p>{{ Form::submit('Create') }}</p>
{{ Form::close() }}
This will generate a URL similar to:
这将生成类似于以下内容的 URL：
<form method="POST" action="http://localhost/couples/create/hello" accept-charset="UTF-8">
Then the rest of your code should work without an issue, and $var1should be set to the value of hello.
然后您的其余代码应该可以正常工作，并且$var1应该设置为hello.

I just saw that the error with the missing parameter appears while having this route:
我刚刚看到在这条路线上出现了缺少参数的错误：
Route::post('couples/done', 'CouplesController@postCreate');
when I take this route out it gives me this error:
当我走这条路线时，它给了我这个错误：
Unknown action [CouplesController@postCreate].
未知操作 [CouplesController@postCreate]。
like it doesn't have access to the controller in the view itself.
就像它无权访问视图本身中的控制器一样。
