Question

我需要使用my laravel刀片文件中的else条件。打印不同的图标。这是我当前的刀片文件

@foreach ($project->tasks as $task)
  <ul>
    <li>
  <div>
  <div class="pull-right icons-align">
            <a href="{{url('projects/'.$project->id.'/task/'.$task->id.'/subtask')}}" class="editInline"><i class="glyphicon glyphicon-plus"></i></a>
            <a href="/projects/{{ $project->id }}/tasks/{{ $task->id }}/edit" class="editInline"><i class="glyphicon glyphicon-pencil"></i></a>
            <a href="" class="editInline"><i class="glyphicon glyphicon-trash"></i></a>
        </div>
    <h4><i class="fa fa-check-square-o"></i> <span><a href="/projects/{{$project->id}}/tasks/{{ $task->id }}">{{ $task->task_name }}</a>

    </span></h4>
 </div>
 </li>
 </ul>
  <hr>
@endforeach

我需要这样一个刀片文件

@if (Auth::user()->id)->exists()) {
 @foreach ($project->tasks as $task)
  <ul>
    <li>
  <div>
  <div class="pull-right icons-align">
            <a href="{{url('projects/'.$project->id.'/task/'.$task->id.'/subtask')}}" class="editInline"><i class="glyphicon glyphicon-plus"></i></a>
            </div>
    <h4><i class="fa fa-check-square-o"></i> <span><a href="/projects/{{$project->id}}/tasks/{{ $task->id }}">{{ $task->task_name }}</a>

    </span></h4>
 </div>
 </li>
 </ul>
  <hr>
@endforeach

else
 @foreach ($project->tasks as $task)
  <ul>
    <li>
  <div>
  <div class="pull-right icons-align">
            <a href="{{url('projects/'.$project->id.'/task/'.$task->id.'/subtask')}}" class="editInline"><i class="glyphicon glyphicon-plus"></i></a>
            <a href="/projects/{{ $project->id }}/tasks/{{ $task->id }}/edit" class="editInline"><i class="glyphicon glyphicon-pencil"></i></a>
            <a href="" class="editInline"><i class="glyphicon glyphicon-trash"></i></a>
        </div>
    <h4><i class="fa fa-check-square-o"></i> <span><a href="/projects/{{$project->id}}/tasks/{{ $task->id }}">{{ $task->task_name }}</a>

    </span></h4>
 </div>
 </li>
 </ul>
  <hr>
@endforeach

我该如何配置？

Answer 1

我在你的代码中发现的错误很少见没有using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Xml; using System.Xml.Linq; namespace ConsoleApplication1 { class Program { const string FILENAME = @"c:\temp\test.xml"; static void Main(string[] args) { XmlReaderSettings settings = new XmlReaderSettings(); settings.ConformanceLevel = ConformanceLevel.Fragment; XmlReader reader = XmlReader.Create(FILENAME,settings); while (!reader.EOF) { if (reader.Name != "root") { reader.ReadToFollowing("root"); } if (!reader.EOF) { XElement root = (XElement)XElement.ReadFrom(reader); } } } } }的{{1}}，如果不应该使用else，则首先使用@。你也错过了关闭{。

这是代码

@endif

Answer 2

下面显示如何使用laravel blade

语句

您可以使用@ if，@ elseif，@ else和@endif指令构造if语句。这些指令的功能与它们的PHP对应程序完全相同：

@if (count($records) === 1)
    <p>I have one record!</p>
@elseif (count($records) > 1)
    <p>I have multiple records!</p>
@else
   <p> I don't have any records! </p>
@endif

如何在Laravel应用程序的我的刀片文件中使用if else条件？
