数据插入后页面未在 Laravel 控制器中重定向

Question

在提交数据并在 laravel 中成功插入数据后，我尝试将页面重定向到表单或主页，但错误显示找不到该页面。请帮我。 我的控制器代码是 testing.php

<?php

namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Request;

use App\test;

class testing extends Controller
{
    /**
     * Display a listing of the resource.
     *
     * @return \Illuminate\Http\Response
     */
    public function index()
    {
        return view('create');
    }

    /**
     * Show the form for creating a new resource.
     *
     * @return \Illuminate\Http\Response
     */
    public function create()
    {
        //
    }

    /**
     * Store a newly created resource in storage.
     *
     * @param  \Illuminate\Http\Request  $request
     * @return \Illuminate\Http\Response
     */
    public function store(Request $request)
    {
        //store data in database
        test::create(Request::all());
       echo "data enserted Successfully";
       ?><a href="<?php return redirect()->action('HomeController@index');?>">Go Back Home</a><?php  

    }

    /**
     * Display the specified resource.
     *
     * @param  int  $id
     * @return \Illuminate\Http\Response
     */
    public function show($id)
    {
        //
    }

    /**
     * Show the form for editing the specified resource.
     *
     * @param  int  $id
     * @return \Illuminate\Http\Response
     */
    public function edit($id)
    {
        //
    }

    /**
     * Update the specified resource in storage.
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  int  $id
     * @return \Illuminate\Http\Response
     */
    public function update(Request $request, $id)
    {
        //
    }

    /**
     * Remove the specified resource from storage.
     *
     * @param  int  $id
     * @return \Illuminate\Http\Response
     */
    public function destroy($id)
    {
        //
    }
}

并给出了create.blade.php形式的视图文件

    @extends('master')

@section('content') 

<div class="container"><br>
        <h1 class="text-success text-center">Student Registration Form</h1><br>

我想在 HomeController@index 中重定向 plearning 视图并给出它的代码

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

class HomeController extends Controller
{
    //
    public function index(){
        return view('plearning');
    }


}

请更正我的代码并帮助我。在此先感谢

Answer 1

要在发布后重定向，您应该将 store 方法更新为以下内容：

public function store(Request $request)
{
    //store data in database
    Test::create($request->all());

    return redirect()->route('test.index');
}

如果这个 test.index 不起作用，我不确定你是如何定义你的路由的，将你的路由发布到你的问题。

您的测试路线应如下所示：

Route::group(['prefix' => 'test', 'as' => 'test.'], function () {
    Route::get('/', ['as' => 'index', 'uses' => 'TestController@index']);
    Route::get('create', ['as' => 'create', 'uses' => 'TestController@create']);
});

Answer 2

你几乎是对的

public function store(Request $request)
{
   //store data in database
   test::create(Request::all());
   return redirect()->action('HomeController@index'); 
}

控制器不适用于 HTML。您尝试在控制器中添加一个用于重定向的 Button，不建议这样做。

对于 Laravel 中的重定向，我们有 redirect()helper_function。

如果仍然出现“找不到页面”错误，请确保视图目录中有“plearning.blade.php”（默认：resource/views）。
