    第9章 TP5.0视图和模板

    ========================================================================

    今日学习

    1、视图

            

             a) 加载页面

                       1、继承系统控制器类

                                return $this->fetch(参数1,参数2,参数3,参数4);

                                参数1(字符串): 模板渲染

                                参数2(数组): 模板赋值

                                参数3(数组): 模板替换

                                参数4(数组):

                       2、使用助手函数

                                // return view();

                                # view的参数与fetch相同

                       3、使用view类 (不建议)

                                $view=new View();

                                return $view->fetch();

             b) 模板赋值

                       1、控制器类中的assign方法

                           // $this->assign('name',$name);

                           // $this->assign('city',$city);

                                // 加载页面

                                // return view();

                       2、通过fetch方法

                                // return $this->fetch('',['name'=>$name,'city'=>$city]);

                       3、助手函数

                                // return view('',['name'=>$name,'city'=>'西安']);

                       4、对象赋值

                                $this->view->name="浩哥";

                                $this->view->city="临汾";

                                return view();

             c) 模板替换   

                       1、配置文件更改(全局替换)

                                // 视图输出字符串内容替换

                                'view_replace_str'       => [

                                    '__HOMES__'=>'/static/home/public',

                                    '__ADMINS__'=>'/static/admin/public',

                                ],

                       2、部分替换

                                1、fetch 方法

                                         return $this->fetch('',[],['__HOMES__'=>'/static/home/public']);

                                2、view 函数

                                         return view('',[],['__HOMES__'=>'/static/home/public']);

             d) 模板渲染

                       1、默认加载当前模块 当前控制器 当前方法对应的页面

                                // return $this->fetch();

                       2、加载当前模块 当前控制器下的 用户定义页面

                                // return $this->fetch('jiazai');

                       3、加载当前模块 User控制器 jiazai页面

                                return $this->fetch('User/jiazai');

    2、模板

            

             1、模板标签

                       1、普通标签

                                // 模板引擎普通标签开始标记

                                'tpl_begin'    => '<{',

                                // 模板引擎普通标签结束标记

                                'tpl_end'      => '}>',

                                <h2>{$str}</h2>

                       2、标签库标签

                                // 标签库标签开始标记

                                'taglib_begin' => '{',

                                // 标签库标签结束标记

                                'taglib_end'   => '}',

                                {for start="1" end="10"}

                                         {$i}

                                {/for}

             2、输出变量

                       1、字符串

                           $this->assign("str","TP5.0 非常简单非常适合初学者");

                                <h2>{$str}</h2>

                       2、数组

                                $data=[

                                         'name'=>'张三',

                                         'age'=>18,

                                         'sex'=>'妖'

                                ];

                                $this->assign("data",$data);

                                <h2>{$data['name']}</h2>

                                <h2>{$data.age}</h2>

             3、使用函数

                       1、竖线

                                <h2>{$pass|md5}</h2>

                                <!-- <h2><?php echo md5($pass); ?></h2> -->

                                <h2>{$time|date="Y-m-d H:i:s",###}</h2>

                                <!-- <?php echo date("Y-m-d H:i:s",$time);?> -->

                                <h2>{$pass|md5|strtoupper|substr=0,10}</h2>

                                <!-- <h2><?php echo substr(strtoupper(md5($pass)),0,10); ?></h2> -->

                       2、冒号开始

                                <h2>{:md5($pass)}</h2>

                                <h2>{:date('Y-m-d H:i:s',$time)}</h2>

             4、默认值

                       <h2>{$name|default="小云"}</h2>

                       <h2><?php echo (isset($name) && ($name !== '')?$name:"小云"); ?></h2>

             5、三元运算符

                       <h2>{$status?'正常':'错误'}</h2>

                       <h2>{$status>2?'正常':'错误'}</h2>

                       <h2><?php echo !empty($status) && $status>2?'正常':'错误'; ?></h2>

             6、运算符

                       <h2>{$a}+{$b}={$a+$b}</h2>

                       <h2>{$a}-{$b}={$a-$b}</h2>

                       <h2>{$a}*{$b}={$a*$b}</h2>

                       <h2>{$a}/{$b}={$a/$b}</h2>

                       <h2>{$a}%{$b}={$a%$b}</h2>

                       <h2>{$a++}</h2>

                       <h2>{$b--}</h2>

             7、原样输出

                       {literal}

                                <h2>hello {$name}</h2>

                       {/literal}

             8、系统变量

                       1、系统变量

                                支持输出  $_SERVER 、 $_ENV 、$_POST 、$_GET 、$_REQUEST 、 $_SESSION 和$_COOKIE变量。

                                <h1>{$_GET['id']}</h1>

                                <h1>{$Think.get.id}</h1>

                                <h1>{$_SERVER['HTTP_HOST']}</h1>

                                <h1>{$Think.SERVER.http_host}</h1>

                       2、常量输出

                                # 常量详见附录

                                <h1>{$Think.const.app_path}</h1>

                                <h1>{$Think.app_path}</h1>

                                <h1>{$Think.ds}</h1>

                                <h1>{$Think.think_path}</h1>

                                <h1>{$Think.IS_WIN}</h1>

                                <h1>{$Think.THINK_VERSION}</h1>

                       3、配置文件输出

                                # 常看配置文件

                                <h2>{$Think.config.app_namespace}</h2>

                                <h2>{$Think.config.default_lang}</h2>

             9、模板注释

                       <h1>{//$_GET['id']}</h1>

                       <h1>{/*$Think.get.id*/}</h1>

             10、包含文件

                       {include file="Public/header"}

                       {include file="Public/footer,Public/footer"}

             11、模板布局

                       1、在视图目录下新建文件 layout.html

                                (C:AppServwww p5applicationadminview)

                       2、在layout.html页面中

                                将所有的公共页面保留,非公共页面使用{__CONTENT__}替代

                                # {__CONTENT__} 只能存在一个

                       3、页面中如何书写

                                # 引入模板布局

                                {layout name="layout"/}

                                # 非公共区域内容

                                <!-- 内容 -->

                                <div class="col-md-10">

                                         <div class="jumbotron">

                                                 <img src="__ADMINS__/img/4.jpg"height="310px" width="100%" alt="">

                                                 <h2>联想 后台管理系统</h2>

                                                 <p>开发者 : 赵丰泰</p>

                                         </div>

                                </div>

             12、模板继承

                       1、在视图目录下新建base.html

                       2、在base.html中对页面进行分割

                                <div class="container">

                                         {block name="nav"}{/block}

                                         <div class="row body">

                                                   {block name="menu"}{/block}

                                                   {block name="main"}{/block}

                                                  

                                         </div>

                                </div>

                       3、使用继承

                                {extend name="base" /}

                                {block name="nav"}

                                         {include file="public/nav" /}

                                {/block}

                                {block name="main"}

                                         <div class="jumbotron">

                                                 <h2>联想 后台管理系统</h2>

                                                 <p>开发者 : 赵丰泰</p>

                                         </div>

                                {/block}

             13、内置标签

                       1、volist循环

                                name               需要遍历的数据

                                id                   类似于foreach中 value

                                offset      截取数据起始位置

                                length      截取数据的个数

                                mod                  奇偶数

                                empty       数据为空的使用

                                key                      编号

                       2、foreach循环

                                name     需要遍历的数据

                                item 类似于foreach中的value

                                key            类似于foreach中的key

                                {foreach name="data" item="val" key="abc"}

                                         <p> {$abc} {$val.id} {$val.name}</p>

                                {/foreach}

                       3、for循环

                                start            开始值

                                end                    结束值

                                comparison  比较条件

                                step                  步数

                                name                循环变量名 默认 i

                                {for start="0" end="10" comparison="elt" step="2" name="abc"}

                                         <p>{$abc}</p>

                                {/for}

                                {for start="10" end="0" comparison="gt" step="-1"}

                                         <p>{$i}</p>

                                {/for}

                       4、比较标签

                                {eq name="a" value="11"}正确{/eq}

                                {neq name="a" value="11"}正确{/neq}

                                {lt name="a" value="11"}正确{/lt}

                                {gt name="a" value="11"}正确{/gt}

                                {egt name="a" value="11"}正确{/egt}

                                {elt name="a" value="11"}正确{/elt}

                                {heq name="a" value="11"}正确{/heq}

                                {nheq name="a" value="11"}正确{/nheq}

                       5、if

                                {if condition="$a eq $b"}

                                         <p>a和b数值相等</p>

                                {else /}

                                         <p>a和b数值不相等</p>

                                {/if}

                       6、switch

                                {switch name="week"}

                                         {case value='1'}周一{/case}

                                         {case value='2'}周二{/case}

                                         {default /} 周日

                                {/switch}

                       7、in 和notin比较类似

                                {in name="week" value="0,1,2,3,4,5,6"}

                                         合法的数据

                                {else /}

                                         不合法数据

                                {/in}

                       8、between 和 notbetween

                                {between name="week" value="0,6"}

                                         合法数据

                                {else/}

                                         非法数据

                                {/between}

                       9、原生PHP

                                {php}

                                         echo "123";

                                {/php}

                                <?php

                                         echo "456";

                                 ?>

                       10、嵌套使用
