第8节 Laravel-表单中查看详情及删除

8.1 给HTML添加链接
8.2 实现查看详情
8.3 实现删除

8.1 给HTML添加链接

如下，修改视图文件，添加链接地址

详情修改删除
添加路由：

Route::any('student/detail/{id}', ['uses' => 'StudentController@detail']);

Route::any('student/delete/{id}', ['uses' => 'StudentController@delete']);

创建查看详情页视图 

\resources\views\student\detail.blade.php

@extends('layout/student')

@section('content')
<!-- 自定义内容区域 -->
<div class="panel panel-default">
<div class="panel-heading">学生详情</div>

<table class="table table-bordered table-striped table-hover ">
<tbody>
<tr>
<td width="50%">ID</td>
<td>1</td>
</tr>
<tr>
<td>姓名</td>
<td>sean</td>
</tr>
<tr>
<td>年龄</td>
<td>18</td>
</tr>
<tr>
<td>性别</td>
<td>男</td>
</tr>
<tr>
<td>添加日期</td>
<td>2016-01-01</td>
</tr>
<tr>
<td>最后修改</td>
<td>2016-03-01</td>
</tr>
</tbody>
</table>
</div>
@endsection

8.2 实现查看详情

创建控制器中的 detail 方法：

/**
* 根据id查看用户信息
*
* @param
* @return    void
* @author    webjust [604854119@qq.com]
*/
public function detail($id)
{
$student = Student::find($id);

return view('student/detail', ['student', $student]);
}

在视图中渲染变量：

\resources\views\student\detail.blade.php

<?php
use App\Models\Student;
$students = new Student();
?>
@extends('layout/student')

@section('content')
<!-- 自定义内容区域 -->
<div class="panel panel-default">
<div class="panel-heading">学生详情</div>

<table class="table table-bordered table-striped table-hover ">
<tbody>
<tr>
<td width="50%">ID</td>
<td>{{ $student->id }}</td>
</tr>
<tr>
<td>姓名</td>
<td>{{ $student->name }}</td>
</tr>
<tr>
<td>年龄</td>
<td>{{ $student->age }}</td>
</tr>
<tr>
<td>性别</td>
<td>{{ $students->sex($student->sex) }}</td>
</tr>
<tr>
<td>添加日期</td>
<td>{{ date('Y-m-d', $student->created_time) }}</td>
</tr>
<tr>
<td>最后修改</td>
<td>{{ date('Y-m-d', $student->updated_time) }}</td>
</tr>
</tbody>
</table>
</div>
@endsection

8.3 实现删除

在控制器中实现删除操作：

/**
* 删除操作
*
* @param
* @return    void
* @author    webjust [604854119@qq.com]
*/
public function delete($id)
{
$student = Student::find($id);

if($student->delete())
{
return redirect('/')->with('success', '删除成功-'.$id);
} else {
return redirect()->back()->with('error', '删除失败-'.$id);
}
}

在删除时，添加一个提示窗口：

<a onclick="if(confirm('确认删除吗?') == false) return false;"
href="{{ url('student/delete', ['id' => $student->id]) }}">删除</a>

效果显示：
