问题描述

如果我以John身份登录，我怎样才能显示John的红色按钮而不是Susan的红色按钮？

If I logged in as John, how can I show only the red button for John instead of Susan's one?

测试系统环境：Win10，Laravel5 .4，Mysql5.7.19。

<table class="table table-responsive" id="jobs-table">
    ...
    @foreach($jobs as $job)
        <tr>
            <td>{!! $job->user_name !!}</td>
            ...
            <td>{!! $job->created_at !!}</td>
            <td>
                {!! Form::open(['route' => ['jobs.destroy', $job->id], 'method' => 'delete']) !!}
                <div class='btn-group'>
                    <a href="{!! route('jobs.show', [$job->id]) !!}" class='btn btn-default btn-xs'><i class="glyphicon glyphicon-eye-open"></i></a>
                    <a href="{!! route('jobs.edit', [$job->id]) !!}" class='btn btn-default btn-xs'><i class="glyphicon glyphicon-edit"></i></a>
                    {!! Form::button('<i class="glyphicon glyphicon-stop"></i>', ['type' => 'submit', 'class' => 'btn btn-danger btn-xs', 'onclick' => "return confirm('Are you sure to Stop?')"]) !!}
                </div>
                {!! Form::close() !!}                  
            </td>
        </tr>
    @endforeach

推荐答案

据我了解，您只想在属于该用户的行上显示该按钮。

From what I understand, you only want to show that button on the rows that belong to that user.

这是一个轻微的假设，但我假设该作业上有某种用户标识符行 - 理想情况下类似 user_id 将行链接到关联用户。

This is a slight assumption, but I assume there is some sort of user identifier on that job row - ideally something like a user_id that links the row to the associated user.

如果是这种情况那么你只需对该按钮使用简单的if语句。

If that's the case then you can just use a simple if statement for that button.

如下所示的内容适用于您拥有的内容：

Something like the below would work with what you have:

@if ($job->user_id == Auth::id())
    {!! Form::button('<i class="glyphicon glyphicon-stop"></i>', ['type' => 'submit', 'class' => 'btn btn-danger btn-xs', 'onclick' => "return confirm('Are you sure to Stop?')"]) !!}
@endif

如果您不使用用户标识符并仅存储用户名，那么类似下面的内容将起作用 - 使用user_name（我认为这是唯一的？）：

If you don't use a user identifier and only store the username then something like the below would work - using the user_name (I assume this is unique?):

@if ($job->user_name == Auth::user()->user_name)
    {!! Form::button('<i class="glyphicon glyphicon-stop"></i>', ['type' => 'submit', 'class' => 'btn btn-danger btn-xs', 'onclick' => "return confirm('Are you sure to Stop?')"]) !!}
@endif
