【中文标题】Laravel：如何在路由中传递单个 ID

【英文标题】：Laravel: How can I pass a single ID in route

【发布时间】：2021-01-04 15:03:36

【问题描述】：

我正在构建一个系统，以便用户可以请求多个事物，并且我希望能够可视化系统中提出的每个请求（单独）的详细信息。 当前的方法一次给了我所有东西，而不是分开。

这是部分代码

控制器

 public function verDetalhesKeys($id)
  
    $detalhes = DB::table('keysRequest')  
    ->where('keysRequest.id','=', $id)
    ->select('keysRequest.*')
    ->get();

    return view('Admin.keysRequestDetails',compact('detalhes'));

路线

Route::get('/detalhesK/id', 'AdminController@verDetalhesKeys') -> name('detalhesK');

<table class="table table-striped">
    <thead>
        <tr>
            <th>Name</th>
            <th>Email</th>
            <th>Department</th>
            <th>Site</th>
            <th>Pourpose</th>
            <th>From</th>
            <th>To</th>
        </tr>
    </thead>
    <tbody>
        @foreach($keys as $s)
        <tr>
            <td>$s->name</td>
            <td>$s->email</td>
            <td>$s->department</td>
            <td>$s->site</td>
            <td>$s->purpose</td>
            <td>$s->till</td>
            <td>$s->until</td>
            <td style="display:none;">$s->id</td>
            <td><a class="btn btn-info btn-md" href=" route('detalhesK',['id' => $s->id])" style="background-color:#00a3b3;"><i class="fa fa-eye" aria-hidden="true"></i></a></td>
        </tr>
        @endforeach
    </tbody>
</table>

【问题讨论】：

所以你想做一个“比较产品”页面？

不，我想对上述产品页面做一些完整的细节

【参考方案1】：

首先是“id”列到数据库表中的主键，您需要确保它是这样，这样您就不会拥有重复的产品。将您的查询编辑到$detalhes = DB::table('keysRequest')->find(id);。 之后，不需要使用循环来输出您的结果，因为它只有一项。只需使用$detalhes->something
