Laravel返回页面，使用旧输入进行验证 [英] Laravel Back to page with old input for validation

问题描述

对于更新配置文件"页面

For the Update Profile Page

我将路线用作

Route::get('editdriver/{data}', 'DriverController@EditDriver');

在我使用验证后的控制器中，

And in the controller after validation i use,

return Redirect::to('editdriver/'.$data)->withInput()->withErrors($validation->messages());

因此，该网址将为

http://localhost/project/editdriver/1

如果我清空rule中所需的值，然后按提交表单，

If i empty the value which is required in the rule and press submit the form,

它显示带有验证消息的旧数据.

It shows the old data with the validation message.

我需要的是，它不应显示来自数据库的旧值.

我什至尝试过

return Redirect::back()->withErrors($validation->messages());

我该怎么做??

在控制器中，我有

public function EditDriver($data=NULL)
    {
        $editvehicle=$data;
        $DriverDetails = DriverModel::where('DriverId', $editvehicle)->get()->toArray();

        return View::make('home/editdriver')->with('DriverDetails', $DriverDetails);
    }

我认为

$("#Firstname").val("<?php echo $DriverDetails[0]['Firstname']?>");

并从jquery到html显示为

And displaying from jquery to html as

{{ Form::text('Firstname',null, array('id'=> 'Firstname')) }}

推荐答案

我不知道为什么要使用jQuery填写表单-这没有意义，应该删除该代码.

I have no idea why you are using jQuery to fill in your form - that makes no sense and you should remove that code.

您需要的只是这一行代码:

All you need is this one line of code:

{{ Form::text('Firstname', Input::old('Firstname', $DriverDetails[0]['Firstname']), array('id'=> 'Firstname')) }}

使用Input::old($DriverDetails[0]['Firstname'])将使用数据库值预填充初始表单-但是如果出现验证错误，则将使用任何输入的"值填充表单

Using Input::old($DriverDetails[0]['Firstname']) will prefill the inital form with your database value - but will then fill in the form with any 'inputted' values if there is a validation error

并确认-您的原始return语句看起来正确:

And to confirm - your original return statement looks correct:

return Redirect::to('editdriver/'.$data)->withInput()->withErrors($validation->messages());
