Laravel 5输入旧为空 [英] Laravel 5 input old is empty

问题描述

我的路线在这里

My routes is here

Route::get('sign-up', ['as' => 'signUp', 'uses' => 'UserController@signUpGet']);
Route::post('sign-up', ['as' => 'signUpPost', 'uses' => 'UserController@signUpPost']);

控制器

return redirect('signUp')->withInput();

然后查看

    <form role="form" method="POST" action="{{route('signUpPost')}}"> 
        <input type="text" class="form-control" name="username" value="{{ old('username') }}">
</form>

{{old()}}函数返回空值.

The {{old()}} function return empty value.

NotFoundHttpException in RouteCollection.php line 145:

推荐答案

您的问题似乎根本没有真正提交用户名:

Your problem looks like you are not actually submitting the username in the first place:

<form role="form" method="POST" action="{{route('signUpPost')}}"> 
        <input type="text" class="form-control" name="username" value="{{ old('username') }}">
</form>

表单内没有提交"按钮.如果您在表格外提交-那么username将不包括在内.

There is no 'submit' button inside the form. If you submit outside the form - then the username will not be included.

在表单内添加提交"按钮-然后重试

Add the submit button inside your form - then try again

<form role="form" method="POST" action="{{route('signUpPost')}}"> 
        <input type="text" class="form-control" name="username" value="{{ old('username') }}">
        <input type="submit" value="Submit">
</form>

编辑-您的控制器也是错误的.应该是这样:

Edit - also your controller is wrong. It should be this:

 return redirect()->route('signUp')->withInput();
