How does laravel return a success message?

Question

If the save fails, this is the code

<code>return redirect()->back()->withInput()->withErrors('保存失败！');</code>

If the save is successful, how to return if there is a template?

<code>return redirect('/模版)->??????('保存成功');</code>

Or a prompt of success appears in the template

<code>return redirect('/模版)->with('保存成功',$ok);  //总不能一直显示。。</code>

router:

<code>
    Route::get('/config', 'ConfigsController@index');

    Route::post('config/add', [
        'as' => 'add',
        'uses' => 'ConfigsController@add'
    ]);</code>

Controller

<code><?php namespace App\Http\Controllers\Admin;

use App\Http\Requests;
use App\Http\Controllers\Controller;

use Illuminate\Http\Request;
use App\Configs;

use Input;
use Illuminate\Http\Response;


class ConfigsController extends Controller {


    /**
     * 显示配置页面，从数据库ID=1获取
     */

    public function index()
    {
        $config_view = Configs::find(1);
        return view('admin.write_config')->with('config_db',$config_view);
    }

    /**
     * 提交更新数据，表单验证
     */

    public function add(Request $request)
    {



        $this->validate($request, [
                'web_name' => 'required',
                'web_add' =>'required',
                'web_email' => 'required|email',
                'web_copy' => 'required',
                'web_keywords' => 'required',
                'web_description' => 'required',
            ]
        );


        $configs = Configs::find(1);

        $configs->web_name = Input::get('web_name');
        $configs->web_add = Input::get('web_add');
        $configs->web_email = Input::get('web_email');
        $configs->web_copy = Input::get('web_copy');
        $configs->web_keywords = Input::get('web_keywords');
        $configs->web_description = Input::get('web_description');



        //判断，如果通过验证，那么第一步跳转到config页面，并且显示成功
        if ($configs->save()) {
            return redirect('/admin/config')->with('status', 'Update Success! 成功！ :)');
        } else {
            return redirect()->back()->withInput()->withErrors('保存失败！');
        }

    }

}

Template page

<code>@extends('admin.admin')

@section('content')

    <p class="home_con">
        <h3>基本设置</h3>


        <form method="post" action="/admin/config/add" class="forms">

Answer 1

First of all, my personal understandingredirect()并不是redirect('/模板')，而是redirect('/routePath'), if you want to use it like this, for example, implement the following jump:

<code>return redirect('success')->with('status', 'Profile updated!');</code>

The general process is like this, first you have to register your route in routes.php, for example:

<code>Route::get('/success','UsersController@storeSuccess');
</code>

Then the UsersController的storeSuccess method usually has the following statement:

<code>return view('users.success');</code>

Finally, you can use a statement similar to the following in success.blade.php to get the jump information:

<code>@if (session('status'))
    <p class="alert alert-success">
        {{ session('status') }}
    </p>
@endif</code>

The status就是最开始redirect()->with()中的status，理解为key。用session取这个key here is fine

Finally, if you want to learn laravel, you can check out the community I just launched. There are a series of articles and tutorials here, and I will try to record videos later:
