本篇概要：
1. 静态资源管理以及模板布局；
-
public/statics/导入 Bootstrap 以及 jQuery 类库 - 新建
App/Http/Controllers/StudentController.php
<?php
namespace App\Http\Controllers;
class StudentController extends Controller{
// 列表页
public function index(){
return view('student.index');
}
}
-
routes/web.php新建一条路由
<?php
Route::get('student/index', ['uses' => 'aaa@qq.com']);
- 新建公共视图文件
resources/views/common/layouts.blade.php

<strong>失败!</strong> 操作失败提示！
</div>
- 新建视图文件
resources/views/student/index.blade.php
@extends('common.layouts')
@section('content')
<!-- 加载提示信息 -->
@include('common.message')
<!-- 自定义内容区域 -->
<div class="panel panel-default">

</ul>
</div>
@stop
2. 表单列表及分页实现；
- 使用 ORM 的方式实现
- 新建
app/Student.php
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
class Student extends Model{
// 指定表名
protected $table = 'student';
// 指定主键
protected $primaryKey = 'id';
// 自定义时间戳
public $timestamps = true;
public function getDateFormat(){
return time();
}
protected function asDateTime($val){
return $val;
}
}
- 修改
App/Http/Controllers/StudentController.php
<?php
namespace App\Http\Controllers;
use App\Student;
class StudentController extends Controller{
// 列表页
public function index(){
//$student = Student::get();
$student = Student::orderBy('id','desc')->paginate(2); // 分页，每页显示 2 条
return view('student.index',[
'students' => $student
]);
}
}
- 修改视图文件
resources/views/student/index.blade.php
@extends('common.layouts')
@section('content')
<!-- 加载提示信息 -->
@include('common.message')
<!-- 自定义内容区域 -->
<div class="panel panel-default">
<div class="panel-heading">学生列表</div>
<table class="table table-striped table-hover table-responsive">
<thead>
<tr>
<th>ID</th>
<th>姓名</th>
<th>年龄</th>
<th>性别</th>
<th>添加时间</th>
<th width="120">操作</th>
</tr>
</thead>
<tbody>
@foreach($students as $student)
<tr>
<th scope="row">{{ $student->id }}</th>
<td>{{ $student->name }}</td>
<td>{{ $student->age }}</td>
<td>{{ $student->gender }}</td>
<td>{{ date('Y-m-d H:i:s', $student->created_at) }}</td>
<td>
<a href="">详情</a>
<a href="">修改</a>
<a href="">删除</a>
</td>
</tr>
@endforeach
</tbody>
</table>
</div>
<!-- 分页 -->
<div>
<div class="pull-right">
{{ $students->render() }}
</div>
</div>
@stop
- 访问：http://192.168.1.214:2000/student/index ，表单列表以及分页实现
3. 通过表单实现新增及操作状态提示功能；
-
通过表单实现模型新增和 create 新增
-
提交到当前方法和指定方法
-
修改
App/Http/Controllers/StudentController.php
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Session;
use App\Student;
class StudentController extends Controller{
// 列表页
public function index(){
//$student = Student::get();
$student = Student::orderBy('id','desc')->paginate(2); // 分页，每页显示 2 条
return view('student.index', [
'students' => $student
]);
}
// 添加页面 & 提交方法
public function create(Request $request){
// 提交到当前方法
if($request->isMethod('POST')){
$data = $request->input('Student');
if(Student::create($data)){
return redirect('student/index')->with('success', '添加成功'); // 闪存信息
}else{
return redirect()->back();
}
}
return view('student.create');
}
// 提交到指定方法：action="{{ url('student/save') }}"
// 保存添加
public function save(Request $request){
$data = $request->input('Student');
// 获取模型
$student = new Student();
$student->name = $data['name'];
$student->age = $data['age'];
$student->gender = $data['gender'];
if($student->save()){
return redirect('student/index');
}else{
return redirect()->back();
}
}
}
- 修改
app/Student.php
<?php
// Model 里添加：设置批量赋值
protected $fillable = ['name', 'age', 'gender'];
- routes/web.php 新建两条路由并修改
<?php
// 中间件使用 session，以及防止 xss 攻击
Route::group(['middleware' => ['web']], function(){
Route::get('student/index', ['uses' => 'aaa@qq.com']);
Route::any('student/create', ['uses' => 'aaa@qq.com']);
Route::post('student/save', ['uses' => 'aaa@qq.com']);
});
- 修改公共视图文件
resources/views/common/layouts.blade.php - 修改 “左侧菜单区域” 代码，添加链接
<!-- 左侧菜单区域，修改部分代码 -->
<div class="col-md-3">
@section('leftmenu')
<div class="list-group">
<a href="{{ url('student/index') }}" class="list-group-item
{{ Request::getPathInfo() != '/student/create' ? 'active' : ''}}
">学生列表</a>
<a href="{{ url('student/create') }}" class="list-group-item
{{ Request::getPathInfo() == '/student/create' ? 'active' : ''}}
">新增学生</a>
</div>
@show
</div>
- 新建视图文件
resources/views/student/create.blade.php
@extends('common.layouts')
@section('content')
<!-- 自定义内容区域 -->
<div class="panel panel-default">
<div class="panel-heading">新增学生</div>
<div class="panel-body">
<!-- 1. 提交到指定方法 -->
<!-- <form class="form-horizontal" method="post" action="{{ url('student/save') }}"> -->
<!-- 2. 提交到当前方法 -->
<form class="form-horizontal" method="post" action="">
<!-- 生成一个隐藏的 input 表单，带一个 token 字段 -->
{{ csrf_field() }}
<div class="form-group">
<label for="name" class="col-sm-2 control-label">姓名</label>
<div class="col-sm-5">
<input type="text" name="Student[name]" class="form-control" id="name" placeholder="请输入学生姓名">
</div>
<div class="col-sm-5">
<p class="form-control-static text-danger">姓名不能为空</p>
</div>
</div>
<div class="form-group">
<label for="age" class="col-sm-2 control-label">年龄</label>
<div class="col-sm-5">
<input type="text" name="Student[age]" class="form-control" id="age" placeholder="请输入学生年龄">
</div>
<div class="col-sm-5">
<p class="form-control-static text-danger">年龄只能为整数</p>
</div>
</div>
<div class="form-group">
<label class="col-sm-2 control-label">性别</label>
<div class="col-sm-5">
<label class="radio-inline">

<p class="form-control-static text-danger">请选择性别</p>
</div>
</div>
<div class="form-group">
<div class="col-sm-offset-2 col-sm-10">
<button type="submit" class="btn btn-primary">提交</button>
</div>
</div>
</form>
</div>
</div>
@stop
- 修改公共视图文件
resources/views/common/message.blade.php
<!-- 成功提示框 -->
@if (Session::has('success'))
<div class="alert alert-success alert-dismissible" role="alert">
<button type="button" class="close" data-dismiss="alert" aria-label="Close">
<span aria-hidden="true">×</span>
</button>
<strong>成功!</strong> {{ Session::get('success') }}
</div>
@endif
<!-- 失败提示框 -->
@if(Session::has('error'))
<div class="alert alert-danger alert-dismissible" role="alert">
<button type="button" class="close" data-dismiss="alert" aria-label="Close">
<span aria-hidden="true">×</span>
</button>
<strong>失败!</strong>{{ Session::get('error') }}
</div>
@endif
4. 表单验证及数据保持；
-
控制器验证
-
Validator 类验证
-
数据保持
-
修改
App/Http/Controllers/StudentController.php -
这次只修改了 create() 方法
// 添加页面 & 提交方法
public function create(Request $request){
// 提交到当前方法
if($request->isMethod('POST')){
/*
// 1. 控制器验证
// 如果验证通过了，代码会继续往下执行
// 如果验证没通过，就会重定向到上一个页面，
// 然后会抛出一个异常，并把错误信息存在 Session 中
// 错误信息会分配到所有视图中，
// 在视图中就可以获取到错误信息变量 $errors
// $error 变量有一些方法可以回去到错误信息
// 可以多错误信息进行自定义
$this->validate($request, [
'Student.name' => 'required|min:2|max:20',
'Student.age' => 'required|integer',
'Student.gender' => 'required|integer'
], [
'required' => ':attribute 为必填项',
'min' => ':attribute 最少为两个字符',
'max' => ':attribute 最多为二十个字符',
'integer' => ':attribute 必须为整数'
], [
'Student.name' => '姓名',
'Student.age' => '年龄',
'Student.gender' => '性别'
]); */
// 2. Validator 类验证
$validator = \Validator::make($request->input(), [
'Student.name' => 'required|min:2|max:20',
'Student.age' => 'required|integer',
'Student.gender' => 'required|integer'
], [
'required' => ':attribute 为必填项',
'min' => ':attribute 最少为两个字符',
'max' => ':attribute 最多为二十个字符',
'integer' => ':attribute 必须为整数'
], [
'Student.name' => '姓名',
'Student.age' => '年龄',
'Student.gender' => '性别'
]);
if($validator->fails()){
// withErrors()：手动注册错误信息，把 $validator 对象传入
return redirect()->back()->withErrors($validator)->withInput();
}
$data = $request->input('Student');
if(Student::create($data)){
return redirect('student/index')->with('success', '添加成功'); // 闪存信息
}else{
return redirect()->back();
}
}
return view('student.create');
}
- 新建公共视图文件
resources/views/common/validator.blade.php
<!-- 所有的错误提示 -->
@if(count($errors))
<!-- 取第一条错误 -->
<div class="alert alert-danger">
<ul>
<li>{{ $errors->first() }}</li>
</ul>
</div>
<!-- 取所有错误 -->
<!-- <div class="alert alert-danger">
<ul>
@foreach($errors->all() as $error)
<li>{{ $error }}</li>
@endforeach
</ul>
</div> -->
@endif
- 在视图文件
resources/views/student/create.blade.php中引入resources/views/common/validator.blade.php，并对错误信息的显示、数据保持进行处理
@extends('common.layouts')
@section('content')
@include('common.validator')
<!-- 自定义内容区域 -->
<div class="panel panel-default">
<div class="panel-heading">新增学生</div>
<div class="panel-body">
<!-- 1. 提交到指定方法 -->
<!-- <form class="form-horizontal" method="post" action="{{ url('student/save') }}"> -->
<!-- 2. 提交到当前方法 -->
<form class="form-horizontal" method="post" action="">
<!-- 生成一个隐藏的 input 表单，带一个 token 字段 -->
{{ csrf_field() }}
<div class="form-group">
<label for="name" class="col-sm-2 control-label">姓名</label>
<div class="col-sm-5">
<input type="text" name="Student[name]" value="{{ old('Student')['name'] }}" class="form-control" id="name" placeholder="请输入学生姓名">
</div>
<div class="col-sm-5">
<p class="form-control-static text-danger">{{ $errors->first('Student.name') }}</p>
</div>
</div>
<div class="form-group">
<label for="age" class="col-sm-2 control-label">年龄</label>
<div class="col-sm-5">
<input type="text" name="Student[age]" value="{{ old('Student')['age'] }}" class="form-control" id="age" placeholder="请输入学生年龄">
</div>
<div class="col-sm-5">
<p class="form-control-static text-danger">{{ $errors->first('Student.age') }}</p>
</div>
</div>
<div class="form-group">
<label class="col-sm-2 control-label">性别</label>
<div class="col-sm-5">
<label class="radio-inline">
<input type="radio" name="Student[gender]" value="10"> 未知
</label>
<label class="radio-inline">
<input type="radio" name="Student[gender]" value="20"> 男
</label>
<label class="radio-inline">
<input type="radio" name="Student[gender]" value="30"> 女
</label>
</div>
<div class="col-sm-5">
<p class="form-control-static text-danger">{{ $errors->first('Student.gender') }}</p>
</div>
</div>
<div class="form-group">
<div class="col-sm-offset-2 col-sm-10">
<button type="submit" class="btn btn-primary">提交</button>
</div>
</div>
</form>
</div>
</div>
@stop
5. 通过模型处理单选框；
- 修改模型
app/Student.php
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
class Student extends Model{
// 性别处理：定义三个常量
const GENDER_UN = 10; // 未知
const GENDER_MALE = 20; // 男
const GENDER_FEMALE = 30; // 女
// 指定表名
protected $table = 'student';
// 指定主键
protected $primaryKey = 'id';
// 设置批量赋值
protected $fillable = ['name', 'age', 'gender'];
// 自定义时间戳
public $timestamps = true;
public function getDateFormat(){
return time();
}
protected function asDateTime($val){
return $val;
}
// 性别处理
public function getGender($ind = null){
$arr = [
self::GENDER_UN => '未知',
self::GENDER_MALE => '男',
self::GENDER_FEMALE => '女'
];
if($ind != null){
return array_key_exists($ind, $arr) ? $arr[$ind] : $arr[self::SEX_UN];
}
return $arr;
}
}
- 修改视图文件
resources/views/student/index.blade.php
@extends('common.layouts')
@section('content')
<!-- 加载提示信息 -->
@include('common.message')
<!-- 自定义内容区域 -->
<div class="panel panel-default">
<div class="panel-heading">学生列表</div>
<table class="table table-striped table-hover table-responsive">
<thead>
<tr>
<th>ID</th>
<th>姓名</th>
<th>年龄</th>
<th>性别</th>
<th>添加时间</th>
<th width="120">操作</th>
</tr>
</thead>
<tbody>
<!-- 模型的方法可以通过模型对象去调用 -->
@foreach($students as $student)
<tr>
<th scope="row">{{ $student->id }}</th>
<td>{{ $student->name }}</td>
<td>{{ $student->age }}</td>
<td>{{ $student->getGender($student->gender) }}</td>
<td>{{ date('Y-m-d H:i:s', $student->created_at) }}</td>
<td>
<a href="">详情</a>
<a href="">修改</a>
<a href="">删除</a>
</td>
</tr>
@endforeach
</tbody>
</table>
</div>
<!-- 分页 -->
<div>
<div class="pull-right">
{{ $students->render() }}
</div>
</div>
@stop
- 修改
App/Http/Controllers/StudentController.php - 修改了 create() 方法
<?php
// 添加页面 & 提交方法
public function create(Request $request){
$student = new Student();
// 提交到当前方法
if($request->isMethod('POST')){
/*
// 1. 控制器验证
// 如果验证通过了，代码会继续往下执行
// 如果验证没通过，就会重定向到上一个页面，
// 然后会抛出一个异常，并把错误信息存在 Session 中
// 错误信息会分配到所有视图中，
// 在视图中就可以获取到错误信息变量 $errors
// $error 变量有一些方法可以回去到错误信息
// 可以多错误信息进行自定义
$this->validate($request, [
'Student.name' => 'required|min:2|max:20',
'Student.age' => 'required|integer',
'Student.gender' => 'required|integer'
], [
'required' => ':attribute 为必填项',
'min' => ':attribute 最少为两个字符',
'max' => ':attribute 最多为二十个字符',
'integer' => ':attribute 必须为整数'
], [
'Student.name' => '姓名',
'Student.age' => '年龄',
'Student.gender' => '性别'
]); */
// 2. Validator 类验证
$validator = \Validator::make($request->input(), [
'Student.name' => 'required|min:2|max:20',
'Student.age' => 'required|integer',
'Student.gender' => 'required|integer'
], [
'required' => ':attribute 为必填项',
'min' => ':attribute 最少为两个字符',
'max' => ':attribute 最多为二十个字符',
'integer' => ':attribute 必须为整数'
], [
'Student.name' => '姓名',
'Student.age' => '年龄',
'Student.gender' => '性别'
]);
if($validator->fails()){
// withErrors()：手动注册错误信息，把 $validator 对象传入
return redirect()->back()->withErrors($validator)->withInput();
}
$data = $request->input('Student');
if(Student::create($data)){
return redirect('student/index')->with('success', '添加成功'); // 闪存信息
}else{
return redirect()->back();
}
}
return view('student.create', [
'student' => $student
]);
}
- 修改视图文件
resources/views/student/create.blade.php
@extends('common.layouts')
@section('content')
@include('common.validator')
<!-- 自定义内容区域 -->
<div class="panel panel-default">
<div class="panel-heading">新增学生</div>
<div class="panel-body">
<!-- 1. 提交到指定方法 -->
<!-- <form class="form-horizontal" method="post" action="{{ url('student/save') }}"> -->
<!-- 2. 提交到当前方法 -->

<button type="submit" class="btn btn-primary">提交</button>
</div>
</div>
</form>
</div>
</div>
@stop
6. 通过表单实现修改；
- 修改视图文件
resources/views/student/index.blade.php
<!-- 只需要添加修改按钮链接 -->
<td>
<a href="">详情</a>
<a href="{{ url('/student/update', ['id' => $student->id ]) }}">修改</a>
<a href="">删除</a>
</td>
- 修改
App/Http/Controllers/StudentController.php
// 新建一个方法
<?php
// 修改
public function update(Request $request, $id){
$student = Student::find($id);
if($request->isMethod('POST')){
$this->validate($request, [
'Student.name' => 'required|min:2|max:20',
'Student.age' => 'required|integer',
'Student.gender' => 'required|integer'
], [
'required' => ':attribute 为必填项',
'min' => ':attribute 最少为两个字符',
'max' => ':attribute 最多为二十个字符',
'integer' => ':attribute 必须为整数'
], [
'Student.name' => '姓名',
'Student.age' => '年龄',
'Student.gender' => '性别'
]);
$data = $request->input('Student');
$student->name = $data['name'];
$student->age = $data['age'];
$student->gender = $data['gender'];
if($student->save()){
return redirect('student/index')->with('success', '修改成功 - '. $id);
}
}
return view('student.update', [
'student' => $student
]);
}
- 修改视图文件
resources/views/student/update.blade.php
@extends('common.layouts')
@section('content')
@include('common.validator')
<!-- 自定义内容区域 -->
<div class="panel panel-default">
<div class="panel-heading">修改学生</div>
<div class="panel-body">
@include('student._form')
</div>
</div>
@stop
- 由于新建学生和修改学生中的 form 表单是通用的，所以提取出来。新建视图文件
resources/views/student/_form.blade.php
<!-- 1. 提交到指定方法 -->
<!-- <form class="form-horizontal" method="post" action="{{ url('student/save') }}"> -->
<!-- 2. 提交到当前方法 -->
<form class="form-horizontal" method="post" action="">
<!-- 生成一个隐藏的 input 表单，带一个 token 字段 -->
{{ csrf_field() }}
<div class="form-group">
<label for="name" class="col-sm-2 control-label">姓名</label>
<div class="col-sm-5">
<input type="text" name="Student[name]" value="{{ old('Student')['name'] ? old('Student')['name'] : $student->name }}"
class="form-control" id="name" placeholder="请输入学生姓名">
</div>
<div class="col-sm-5">
<p class="form-control-static text-danger">{{ $errors->first('Student.name') }}</p>
</div>
