我有一个简单的Lavel 4项目，在提交信息后，我试图简单地重定向到上一页。但是，当插入Redirect::back()时，它只是刷新当前页面。我怎样才能让它正确地重定向到它所在的上一页？
控制器
public function saveCustomer($id) {
$zip_code = DB::table('zip_codes')
->where('zip_code', Input::get('user_zip_code'))
->first();
if (!empty(Input::get('user_id'))) {
$user_id = Input::get('user_id');
$user = User::find($user_id);
$user->user_zip_code = $zip_code->zip_code;
$user->office = $zip_code->office;
$user->save();
} else {
$user_id = NULL;
}
$userdata = [
'user_id' => $user_id,
'first_name' => Input::get('first_name'),
'last_name' => Input::get('last_name'),
'street_1' => Input::get('street_1'),
'street_2' => Input::get('street_2'),
'apartment' => Input::get('apartment'),
'phone_1' => Input::get('phone_1'),
'phone_2' => Input::get('phone_2'),
'state' => 'Alabama',
'user_zip_code' => Input::get('user_zip_code'),
'city' => $zip_code->city
];
$rules = array(
'first_name' => 'required',
'last_name' => 'required',
'street_1' => 'required',
'phone_1' => 'required'
);
$validation = Validator::make($userdata, $rules);
if($validation->fails()){
return Redirect::to("customer/edit/$id")->withErrors($validation)->withInput();
}
UsersInformation::find($id)->update($userdata);
return Redirect::back();
刀片模板
{{ Form::open(array('name' => 'edit customer', 'action' => array('CustomerController@saveCustomer', $customer->id)))}}
@foreach($errors->all() as $error)
<p class="albox errorbox">{{$error}}</p>
@endforeach
<div class="four columns">
@if (isset($customer->first_name))
{{ Form::hidden('user_id', '' . $customer->user_id . '')}}
@endif
<label class="form">First Name:</label> <span class="required"> (required)</span><br />
@if (isset($customer->first_name))
{{ Form::text('first_name', '' . $customer->first_name . '')}}<br />
@else
{{ Form::text('first_name')}}<br />
@endif
<label class="form">Last Name:</label> <span class="required"> (required)</span><br />
@if (isset($customer->last_name))
{{ Form::text('last_name', '' . $customer->last_name . '')}}<br />
@else
{{ Form::text('last_name')}}<br />
@endif
<label class="form">Primary Street:</label> <br />
@if (isset($customer->street_1))
{{ Form::text('street_1', '' . $customer->street_1 . '')}}<br />
@else
{{ Form::text('street_1')}}<br />
@endif
<label class="form">Secondary Street:</label> <br />
@if (isset($customer->street_2))
{{ Form::text('street_2', '' . $customer->street_2 . '')}}<br />
@else
{{ Form::text('street_2')}}<br />
@endif
<label class="form"> Primary Phone Number:</label> <br />
@if (isset($customer->phone_1))
{{ Form::text('phone_1', '' . $customer->phone_1 . '')}}<br />
@else
{{ Form::text('phone_1')}}<br />
@endif
<label class="form">Secondary Phone Number:</label> <br />
@if (isset($customer->phone_2))
{{ Form::text('phone_2', '' . $customer->phone_2 . '')}}<br />
@else
{{ Form::text('phone_2')}}<br />
@endif
<label class="form">Apartment:</label><br />
@if (isset($customer->apartment))
{{ Form::text('apartment', '' . $customer->apartment . '')}}<br />
@else
{{ Form::text('apartment')}}<br />
@endif
<label class="form">City/Zip Code:</label> <span class="required"> (required)</span><br />
<select name="user_zip_code">
<option value='{{{ $customer->user_zip_code }}}'>{{{ $customer->city }}} - {{{ $customer->user_zip_code }}}</option>
@foreach ($zip_code as $zip_codes)
<option value='{{ $zip_codes->zip_code }}'>{{ $zip_codes->city }} - {{ $zip_codes->zip_code }}</option>
@endforeach
</select><br />
<button type="submit" class="button is-success">Save</button><br /><br />
</div>
{{ Form::close() }}
不确定是否需要，但这也是我的route.php页面
Route::get('customer/edit/{id}', 'CustomerController@editCustomer');
当前页面是指表单所在的页面吗？如果是，那么它实际上是重定向回-它进入控制器操作，处理saveCustomer（）中的所有内容，然后重定向回表单页面。
问题是…它是否将用户保存在数据库中？
p.S您应该将所有数据库逻辑都放在模型中，而不是放在控制器中——这会使整个应用程序更加模块化，更容易测试，控制器也更薄。
编辑使用命名路由，并明确重定向到该路由。
Routes.php
Route::get('/customer', array('as' => 'customer', 'uses' => 'MyController@showCustomer'));
Controller.php
function saveCustomer($id) {
...
Redirect::route('customer');
}
使用：
if(isset($_SERVER['HTTP_REFERER']))
return Redirect::back();
return Redirect::to('/');
