Laravel 8-旧输入和验证错误消息不起作用

Laravel 8 - Old inputs and validation error messages are not working(Laravel 8-旧输入和验证错误消息不起作用)

本文介绍了Laravel 8-旧输入和验证错误消息不起作用的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!

问题描述

如果对某一输入的验证与指定字段上的上一次输入一起失败,我会尝试在该字段下方显示错误div。

以下是我到目前为止的进展:
在我的controller文件中store函数(UserController > store)

public function store(Request $request)
{
    $validationRules = array(
        'first_name' => 'required|min:2|max:150',
        'last_name' => 'required|min:2|max:150',
        'gender' => 'required',
        'birthdate' => 'required',
        'user_contact' => 'required|min:10|max:20',
        'email' => 'required|unique:users|max:150'
    );

    $validator = Validator::make($request->all(), $validationRules);

    if($validator->fails()){
        //dd($validator)
        return redirect(route('user.create'))->withInput()->withErrors($validator);
    }

.....

当我尝试使用dd()打印$validator时,它没有任何问题,并且它包含验证错误消息、所有输入和验证规则

以下是create.blade.php (view)

中的代码片段
<form class="form-horizontal" method = "POST" action = "{{ route('user.store') }}">

                    </div>

            </div>
        </div>
        <div class="card-footer">
            <button type="submit" class="btn btn-default float-right" name = "submit_create" id = "submit_create">Submit</button>
        </div>
        </form>

请注意,我删除了autocomplete=off,因为我阅读了一些帖子,认为这会导致问题,但在我的情况下仍然不起作用。

我已经阅读了所有与我的问题相关的Stackoverflow帖子,但大多数场景问题都发生在Laravel 5上,我使用的是Laravel框架的最新版本,也就是Laravel 8。

问题的原因似乎是什么?以及我应该如何保留 旧/以前的输入,并在失败后显示错误消息 验证?我怀疑问题出在刀片式服务器上 文件或与引导等资源相关的文件。

推荐答案

您可以尝试此重定向

        if ($validator->fails())
        {
            return redirect()->back()->withErrors($validator->errors());
        }

在刀片文件中显示时,尝试这个

 @error('user_contact')
        <div style="color: red;">{{ $message }}</div>
 @enderror
