+# 数据分页 paginate
+
+创建分页
+
+数据库DB方式的分页
+```php
+// 每页显示 5 条
+$users = DB::table('users')->paginate(5);
+```
+
+模型创建分页
+```php
+$users = User::paginate(5);
+```
+
+分页按钮直接使用links()方法即可，它继承了Bootstrap样式
+
+```php
+{{$list->links()}}
+```
+
+使用withPath()方法，更改路由地址
+
+```php
+$users->withPath('/users/list');
+```
+指定参数，可以使用appends()方法
+```php
+{{$list->appends(['sort'=>'id'])->links()}}
+```
+
+保存所有查询参数，可以使用withQueryString()方法;
+```php
+{{$list->withQueryString()->links()}}
+```
+
+使用fragment()方法给URL地址#符号
+
+```php
+{{$list->fragment('element')->links()}}
+```
+
+大量分页中...省略分页数量，使用onEachSize()方法可设置外侧数量，默认3
+```php
+ {{$list->onEachSide(1)->links()}}
+```
+
+更多方法
+| 方法 | 描述
+| - | - 
+| $results->count() | 获取当前页数据的数量
+| $results->currentPage() | 获取当前页页码
+| $results->hasPages() | 是否有多页
+| $results->hasMorePages() |  是否有更多页
+| $results->firstItem() | 获取结果集中第一条数据的结果编号
+| $results->getOptions() | 获取分页器选项
+| $results->items() | 获取当前页的所有项
+| $results->lastItem() |  获取结果集中最后一条数据的结果编号
+| $results->lastPage() | 获取最后一页的页码。 (在 simplePaginate 无效)
+| $results->nextPageUrl() | 获取下一页的 URL
+| $results->onFirstPage() | 当前页是否为第一页
+| $results->perPage() | 每页的数据条数
+| $results->getUrlRange($start, | 创建分页 URL 的范围
+| $end) | 
+| $results->previousPageUrl() | 获取前一页的 URL
+| $results->total() | 数据总数(在 simplePaginate 无效)
+| $results->url($page) | 获取指定页的 URL
+| $results->getPageName() | 获取分页的查询字符串变量
+| $results->setPageName($name) | 设置分页的查询字符串变量

+# 表单验证validate
+
+## 表单快速验证
+
+两个路由:一个表单，一个处理表单
+
+```php
+//表单页
+Route::get('/task/form','TaskController@form');
+//接收页
+Route::post('/task/receive','TaskController@receive');
+```
+
+表单
+
+```html
+<form action="/task/receive" method="post">
+    @csrf
+用户名:<input type="text" name="username"> 
+密码:<input type="password" name="password"> 
+<button type="submit">提交</button>
+</form>
+```
+
+表单处理页
+```php
+public function receive(Request $request)
+{
+    // 验证请求方式 
+    // 左边为验证字段，右边为验证规则，每个规则竖线隔开 
+    // 比如 required 不得为空，min 不等小于，max 不得大于 
+    $request->validate([
+        'username'             => 'required|min:2|max:10',
+        'password'             => 'required|min:6', 
+    ]);
+    // 只有通过才能执行下面的语句，否则返回表单页
+    return '恭喜验证通过!'; 
+}
+```
+
+如果验证没有被通过，会自动重定向到提交页，并将错误信息存储到session中
+```php
+// 内部操作是通过中间件:Illuminate\View\Middleware\ShareErrorsFromSession
+@if($errors->any())
+    <div>
+        <ul>
+        @foreach ($errors->all() as $error)
+            <li>   $error   </li>
+        @endforeach
+        </ul> 
+    </div>
+@endif    
+```
+
+也可以单独设置错误信息，使用@error指令
+
+```php
+@error('username')
+        <div>{{  $message }} : 用户名非法!</div>
+@enderror
+
+@error('password')
+    <div> {{  $message }} : 密码非法!</div>
+@enderror
+```
+
+规则写法
+
+```php
+//数组方式验证 
+$request->validate([
+    'username' => ['required', 'min:2', 'max:10'],
+    'password' => ['required', 'min:6'] 
+]);
+```
+
+## 验证类的使用
+
+创建一个验证类
+
+```bash
+php artisan make:request Form
+```
+
+```php
+// Http\Request\Form.php
+public function authorize()
+{
+    // 默认 false，为关闭授权，关闭状态会 403 
+    // 比如判断这个用户是否有操作权限
+    return true;
+}
+
+public function rules()
+{
+    return [ 
+        //规则
+        'username'             => 'required|min:2|max:10',
+        'password'             => 'required|min:6', 
+    ];
+}
+```
+使用验证类
+
+```php
+// 通过验证类验证 
+$request->validated();
+```
+
+设置成中文提示
+```php
+//验证器类方法
+public function messages()
+{
+    return [
+        'username.required' => '用户名不得为空~', 
+        'username.min'      => '用户名不得小于2位~', 
+        'username.max'      => '用户名不得大于10位~',
+        'password.required' => '密码不得为空',
+        'password.min'      => '密码不得小于6位~',
+    ]
+}
+```
+自定义属性名，而其它采用默认提示
+```php
+// 提示语言包在:resources\lang\en\validation.php
+public function attributes()
+{
+    return [
+        'username' => '用户名',
+    ]; 
+}
+```
+
+请求验证之前，修改提交的请求数据
+
+```php
+protected function prepareForValidation()
+{
+    $this->merge([
+        'username' => 'Mr.Lee'
+    ]); 
+}
+```
+
+## 创建手动验证
+
+快速验证方式
+
+```php
+$validateData = $request->validate([
+    'username'             => 'required|min:2|max:10',
+    'password'             => 'required|min:6', 
+]);
+
+//验证通过后得到提交的值 
+dd($validateData);
+```
+
+创建手动验证
+
+```php
+//手动创建验证器
+$validator = Validator::make($request->post(), [
+    'username'             => 'required|min:2|max:10',
+    'password'             => 'required|min:6', 
+]);
+
+//如果没有通过的话
+if ($validator->fails()) {
+    //跳转后，并将错误保存，还可以返回上一次填的信息
+    return redirect('/task/form')
+        ->withErrors($validator)
+        ->withInput();
+}
+```
+
+```php
+// 快速验证，也支持 old 记忆上一次表单数据的功能
+用户名:<input type="text" name="username" value="{{old('username')}}">
+```
+
+设置$errors的多个错误包
+
+```php
+$validator = Validator::make($request->post(), [
+    'username' => 'required|min:2|max:10', 
+    'password' => 'required|min:6',
+])->validateWithBag('post'); 
+// 设置快速验证和手动验证
+
+if ($validator->fails()) { 
+    //适合手动验证
+    return redirect('/task/form')
+        ->withErrors($validator, 'post')
+        ->withInput();
+}
+
+{{--多个错误包调用--}} 
+{{$errors->post}}
+```
+
+在验证完毕之前，通过附加回调添加更多的自定义错误信息
+
+```php
+//验证钩子
+$validator->after(function ($validator) {
+    $validator
+        ->errors()
+        ->add('info', '隐藏字段info的值不存在'); 
+});
+```
+
+$errors对象方法
+
+```php
+any()判断
+all()获取全部
+
+{{--获取指定字段第一条信息--}} 
+{{$errors->first('username')}}
+
+{{--判断指定字段是否有错误信息--}}
+{{$errors->has('username')}}
+```
+

+```
+
+(1) alpha_dash:字段必须由字母、数字破折号(-)和下划线(_)构成;
+
+```php
+'username' => 'required|alpha_dash',
+```
+
+
+(2) between:字段长度必须在指定的区间之间; 
+```php
+'username' => 'required|between:2,6',
+```
+
+(3) .size:6:字段长度固定在某个值; 
+```php
+'username' => 'required|size:6',
+```
+
+(4) .email:字段必须符合 email 格式; 
+```php
+'username'   => 'required|email',
+```
+
+(5) .unique:users:字段值是唯一的，通过指定数据表字段检查;
+```php
+'username'  => 'required|unique:users',
+```
+
+(6) .confiremed:这个基本用于密码和密码确认，固定了字段名称;
+```php
+'password'  => 'required|min:6|confirmed',
+
+<input type="password" name="password_confirmation">
+```
+
+(7) different:password:字段和另一个字段不可以相同的验证;
+
+```php
+'username' => 'required|different:password',
+```
+
+
+(8) .ip/json:字段是否是 ip 地址/字段是否是 json 数据;
+```php
+'username'             => 'required|ip', 'username'             => 'required|json',
+```
+
+其它用法
+
+Rule类
+
+```php
+'username'  => 'required|in:tom,jack,lusy',
+    
+'username' => [ 
+    'required', 
+    Rule::in(['tom', 'jack', 'lusy'])
+],
+```
+
+可以结合where来限制验证范围等操作
+
+```php
+//验证是否重复
+'username'             => Rule::unique('users'),
+
+'username'             => Rule::unique('users')
+                            ->where(function ($query) {
+                                $query->where('id', 20); 
+                            }),
+```
