【中文标题】提交表单数据后，页面未在 laravel 中正确加载【英文标题】：after submitting form data, page not being properly loaded in laravel 【发布时间】：2019-11-14 19:53:00 【问题描述】：

我有一个网站，其中有一个表单，用户提交后的表单数据发送到我的数据库和电子邮件。

下面是我的控制器和路由

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Register;
use App\Mail\SendEmail;

    public function store(Request $request)
    

       // return $request;


// return $request->Fee;

            return back();

    public function destroy($id)

Route::resource('register','RegController');

用户提交注册按钮后，数据被提交，然后用户被带到顶部带有成功消息的表单。问题是当用户第一次提交数据时，页面卡在https://booktheparty.in/TEIA/register，页面空白。然后当用户返回并再次提交时，页面被定向到表单页面并显示成功消息。但仍然将数据添加到数据库中 2 次。我想知道为什么我的页面第一次就卡住了。谁能告诉我

【问题讨论】：

您是否尝试使用 header() 或 redirect() 来测试您的代码是否返回？还会触发一些错误吗？你的 laravel.log 显示了什么？您是否尝试更改return back();到return redirect('/register') ? @Jovs 寄存器是我的 php 代码所在的位置，我要重定向到的页面是“welcomeblade”.. 那是主页，我将如何做到这一点大约第二次“工作”实际上您看到的消息是上一个请求的会话闪存。但正如我和@Jovs 告诉你的那样，你是否尝试将return back(); 更改为return redirect("/register");，因为测试建议你也可以使用 header("Location: register")，但是会话闪存它不会工作。 @FabioWilliamConceição 我是 laravel 的新手，“注册”是我的控制器，我的表单在索引刀片中。您能否建议使用您所说的格式来回答如何做到这一点 【参考方案1】：

请将此代码替换为您的商店功能

            return redirect()->back();

希望对你有用

【参考方案2】：

尝试添加此代码：

return redirect('write the route you want to be redirected ');

在控制器中保存数据后。

【讨论】：

【参考方案3】：

return redirect()->back(); 或 return redirect('')
