在Laravel 4中重定向回时保留表单值 [英] Keep form values when redirect back in Laravel 4

问题描述

当我在Laravel 4上执行Redirect :: back时，我试图保留表单的值，但是我找不到执行此操作的方法.

I'm trying to keep the values of a form when Redirect::back on Laravel 4, but I can't find a way to do this.

这是我的表格:

{{ Form::open(array('route' => 'generate', 'files' => true)) }}

    {{ Form::radio('myType', '1', true); }}
    {{ Form::label('myType', '1'); }}

    {{ Form::radio('myType', '2'); }}
    {{ Form::label('myType', '2'); }}

    {{ Form::radio('myType', '3'); }}
    {{ Form::label('myType', '3'); }}

    {{ Form::text('myName'); }}

    {{ Form::file('uploadImage'); }}

    {{ Form::submit('Go'); }}

{{ Form::close() }}

还有我的控制器:

$validator = Validator::make(Input::all(), array('uploadImage' => 'required|image', 'myName' => 'required'));

if ($validator->fails()){
    return Redirect::back()->withErrors($validator);
}

我尝试过类似的事情:

return Redirect::back()->withErrors($validator)->with('nameValue', Input::get('myName'));

然后在视图中:

    {{ Form::text('myName', $nameValue); }}

但是它仍然不起作用.任何帮助将不胜感激.

But it still doesn't work. Any help will be appreciated.

推荐答案

if ($validator->fails()){
    return Redirect::back()->withErrors($validator);
}

更改为

if ($validator->fails()){
    return Redirect::back()->withErrors($validator)->withInput();
}

您可以通过Input::old()方法检索该值.

you can retreive the value by Input::old() method.

了解更多

您尝试过: return Redirect::back()->withErrors($validator)->with('nameValue', Input::get('myName'));

上面，您可以从Session获取值.

above, you can get the value from Session.

Session::get('nameValue')
