php - 在 laravel 的刀片视图中无法看到警报

问题描述

我正在使用 laravel 检查发布请求，然后在同一页面中显示警报。我尝试使用返回消息返回最后一个 url，但我无法看到该消息。

这是我的控制器功能

namespace App\Http\Controllers;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Response;

use App\Category;
use App\Glassfilm;
use DB;
use Session;


public function checkProduct(Request $request){

    $this->validate($request,[

        'area' => 'required',

    ]);

    if($request->area <= $request->stock){

        //echo "the product is available";
        //echo $request;
        //Session::flash('message', "available");
        echo back();
        // return back()->with(['success' => 'Success']);
    }
    else{

        echo "the product is not available";
        echo $request;
    }

    // echo $request;
}

我的路线

路线::get('/glassfilm/{name}/{id}' , 'GlassFilmController@search_by_id');

Route::post('/checkproduct' , 'GlassFilmController@checkProduct')->name('check-product');

我的观点

@extends ('glassfilm.master')

@section ('title')
        {{$name}}
@endsection

@section('message')

@if(Session::has('success'))
<div class="alert alert-success" role="alert">
  {{ Session::get('success') }}
</div>
@endif

@endsection
@section ('category')

                    <ul class="main-categories">

                        @foreach($category as $category)
                        <li class="main-nav-list"><a href="{{url('/glassfilm/'.$category->category)}}">{{ $category->category }}<span class="number">({{ $category->count}})</span></a></li>
                        @endforeach
                    </ul>
@endsection


@section ('glassfilm')

            <section class="lattest-product-area pb-40 category-list">
                    <div class="row">
                        <!-- single product -->
                        @foreach($filterResult as $glass)



                    <div class="col-lg-3 col-md-6">
                            <div class="single-product">
                                @foreach(json_decode($glass->image) as $key=>$image)
                                    @if($loop->first)
                                        <a href="{{url('/glassfilm/'.$category->category.'/'.$glass->id)}}"><img class="img-fluid" src="{{asset('storage')}}/{{$image}}" alt="" style=" width: 263px; height: 280px "></a>

解决方案

利用

return redirect()->back()->with('success', 'Success');

然后在你的刀片中。

@if (Session::has('success'))
    <div class="alert alert-success">
        <ul>
            <li>{{ Session::get('success') }}</li>
        </ul>
    </div>
@endif
