Laravel 5.4默认成功或错误消息未正确显示

标签： laravel

我正在使用laravel 5.4。我的应用程序中的最近几天我遇到了一个大问题。任何错误或成功消息都无法正确显示。当我创建这些功能时，那些工作正常。所有消息都正确显示。但是从最近几天开始，我面临着这个问题。当我尝试添加一些内容时，如果验证失败，则错误消息有时会显示并显示某些时间。验证成功时也是如此。我可以正确地看到存储在数据库中的那些数据，但是不会一直显示成功消息。有时显示。
这是我来自创建通知

 {!! Form::model($single_notice,['route'=>['notice.update',$single_notice->id],'method'=>'PUT','files'=>true]) !!}
  <div class="col-lg-7">
    <div style="display: block;" id="rulesformitem" class="formitem">
      {{ Form::textarea('notice', null,array('class'=>'form-control notice-textarea')) }}
    </div>
  </div>
@if($single_notice->general == 'general')
  <div class="col-lg-3 text-center" style="margin-top: 15px">
     <label for="rules" id="ruleslabel">Notice For:</label>
     <br>
     <input onclick="document.getElementById('custom').disabled = true; document.getElementById('charstype').disabled = false;" type="radio" name="type" value="general" checked="checked">General
     <br>
      <input onclick="document.getElementById('custom').disabled = false; document.getElementById('charstype').disabled = true;" type="radio" name="type"  >Demo/Final
        <br>
        <label for="rules" id="ruleslabel">Date & Time: <br> 01-01-2017 10(hr):30(m) <small>(This format)</small> </label>
        <br>
        <input type="datetime-local" class="form-control" name="demoOrfinal" id="custom" >
        <br>

  </div>  
  @else
  <div class="col-lg-3 text-center" style="margin-top: 15px">
     <label for="rules" id="ruleslabel">Notice For:</label>
     <br>
     <input onclick="document.getElementById('custom').disabled = true; document.getElementById('charstype').disabled = false;" type="radio" name="type" value="general">General
     <br>
      <input onclick="document.getElementById('custom').disabled = false; document.getElementById('charstype').disabled = true;" type="radio" name="type"  checked="checked">Demo/Final
        <br>
        <label for="rules" id="ruleslabel">Date & Time: <br>
  {{ Carbon\Carbon::parse($single_notice->demoOrfinal)->format('H:i d-m-Y') }}
        </label>
        <br>
        <input type="datetime-local" class="form-control" name="demoOrfinal" id="custom" >
        <br>

  </div>
  @endif
  <div class="col-lg-2 text-center" style="margin-top: 20px">
    <label>Upload File:</label>

    @if($single_notice->image_link != 'null')
    <input type="button" class="form-control" id="loadFileXml" value="Image" style="margin-bottom: 5px" onclick="document.getElementById('image').click();" />
          {{ substr(strip_tags($single_notice->image_link),0,5) }}
          {{ strlen(strip_tags($single_notice->image_link)) > 5 ? "...jpg" : "" }}
    @endif
    <input type="file" style="display:none;" id="image" name="notice_image"/>
    <input type="button" class="form-control" id="loadFileXml" value="PDF" onclick="document.getElementById('pdf').click();" />
    @if($single_notice->pdf_link != 'null')
    <small>{{ substr(strip_tags($single_notice->pdf_link),0,5) }}
          {{ strlen(strip_tags($single_notice->pdf_link)) > 5 ? "...pdf" : "" }}
    </small>

    @endif
    <input type="file" style="display:none;" id="pdf" name="notice_pdf"/>
    <button class="form-control btn-info" style="margin-top: 5px;">Update Notice</button>

  {!! Form::close() !!}

以下是创建通知的方法

public function store(Request $request)
{
    //dd($request);
    $teacher_id = Auth::user()->id;
    $this->validate($request,array(
        'notice'       => 'required|min:5',
        'notice_image' => 'sometimes|mimes:jpeg,jpg,png',
        'notice_pdf'   => 'sometimes|mimes:pdf'
    ));
    if($request->type == 'general')
    {
        $this->validate($request,array(
            'type' => 'required',
        ));   
    }
    if($request->type == 'on') {
        $this->validate($request,array(
        'demoOrfinal' => 'required|date',
        ));
    }
    $add_notice = new Notice;
    $add_notice->notice      = $request->notice;
    $add_notice->general     = $request->type;
    $add_notice->demoOrfinal = $request->demoOrfinal;
    $add_notice->posted_by  = $teacher_id;
    $add_notice->image_link  = $request->notice_image;
    $add_notice->pdf_link    = $request->notice_pdf;

    if ($request->hasFile('notice_image')) {
        $file = $request->file('notice_image');
        $filename = time().'.'.$file->getClientOriginalName();
        $location = public_path('file/'.$filename);
        Storage::put($filename,file_get_contents($file));
        $add_notice->image_link = $filename;

    }

    if ($request->hasFile('notice_pdf')) {
        $file = $request->file('notice_pdf');
        $filename = time().'.'.$file->getClientOriginalName();
        $location = public_path('file/'.$filename);
        Storage::put($filename,file_get_contents($file));
        $add_notice->pdf_link = $filename;

    }
    $add_notice->save();
    Session::flash('success','Notice Has Been Posted. Thanks :-)');
    return redirect()->back();
}

这是我的错误消息显示代码

 @if(Session::has('success'))
 <div class="alert alert-success">
 <button type="button" class="close" data-dismiss="alert" aria- 
 hidden="true">&times;</button>
 <strong>{{ Session::get('success') }}</strong>
 </div>
  @endif
 @if(Session::has('denger-success'))
  <div class="alert alert-danger">
 <button type="button" class="close" data-dismiss="alert" aria- 
  hidden="true">&times;</button>
 <strong>{{ Session::get('denger-success') }}</strong>
 </div>
 @endif
 @if(count($errors))
 <div class="alert alert-danger validation-error-message">
 <button type="button" class="close" data-dismiss="alert" aria- 
 hidden="true">&times;</button>
<strong>Error:</strong>
<ul>
  @foreach($errors->all() as $error)
    <li>
      {{ $error }}
    </li>
  @endforeach
 </ul> 
 </div>
 @endif

抱歉我的英语不好。 提前谢谢。

当您运行php artisan session:table和php artisan migrate时，将.env文件更改为SESSION_DRIVER=database，即可创建并使用“会话”表。

会话架构如下：

Schema::create('sessions', function (Blueprint $table) {
        $table->string('id')->unique();
        $table->text('payload');
        $table->integer('user_id')->nullable();
        $table->string('ip_address')->nullable();
        $table->text('user_agent');
        $table->integer('last_activity');
    });

有效负载的文本太长，会话丢失。如果您'升级'到mediumtext，则可以解决问题。

您可以在数据库中执行此操作，也可以创建新的迁移php artisan make:migration change_payload_in_sessions_table并添加：

Schema::table('sessions', function (Blueprint $table) {
        $table->mediumText('payload')->change();
    });

当然，您需要运行php artisan migrate
