SpringView for Yaf

介绍

在我们以往的大量 PHP 项目中都使用了 鸟哥 贡献的 Yaf 开发框架,Yaf 框架运行效率高(C扩展),结构简单易上手,随PHP更新迭代快,实为“国货之光”。

在 Yaf 的使用过程中,对于视图模板的功能,框架本身自带的 Yaf_View_Simple 对于稍复杂项目开发来说功能过于基础和简陋。后来我们使用另一个开源的 C扩展模板引擎 blitz 继承实现了 Yaf 的视图,基本能满足开发需求。不过随着项目的复杂性增加,以及某些项目准备开源的想法,blitz模板自身迭代慢、有学习门槛、功能不易扩展逐渐成为了一种限制。有鉴于此,我们基于团队以往开发中积累的经验教训,结合最常用的使用需求,开发了 SpringView 视图模板引擎。

SpringView v1.2 的基础上,我们实现了对 Yaf 专门适配的版本:

  1. 对 Yaf_View_Interface 抽象方法的具体实现
  2. 基于 SpringView 简单易用的模板符号语法
  3. 采用文件缓存的方式,提升脚本执行效率
  4. 支持布局视图方式

欢迎访问 SpringView in GiteeSpringView in SpringPHP 了解 SpringView 视图模板引擎的功能及示例演示。

类库方法说明

  1. public 方法
    • __construct($viewPath, $cachePath) 类库初始化
    • assign($spec, $value) 设置视图模板中的变量值
    • render($viewFile, $viewVars) 返回指定视图模板的输出内容
    • display($viewFile, $viewVars) 直接显示指定视图模板的输出内容
    • setJson($json) 设置是否将数据输出为json格式(不使用模板渲染)
    • setLayout($layoutFile, $blockFlagForView) 使用指定的布局视图模板
    • setBlock($blockFlag, $viewFile) 设置布局视图模板中内容块的对应视图文件
    • setScriptPath($viewDirectory) 设置视图模板文件所在目录
    • getScriptPath() 返回视图模板文件所在目录
    • setCachePath($cacheDirectory) 设置视图模板缓存文件所在目录
    • getCachePath() 返回视图模板缓存文件所在目录
    • setCacheLifetime($cacheSeconds) 设置缓存文件的有效时间(秒)
    • getCacheLifetime() 返回缓存文件的有效时间设定值
    • cleanCache($viewFile) 删除指定视图模板的缓存文件
  2. private 方法
    • getCacheFile($viewPathFile) 返回指定视图路径文件的缓存文件(若缓存失效则重新生成)
    • buildCacheFile($viewPathFile, $cachePathFile) 将指定视图模板转换为PHP代码缓存文件并保存
    • parseView($code) 分析处理指定模板代码,返回转换后的PHP代码
    • parseFileTags($code) 分析处理模板代码中的文件引用标签,返回经过转换的代码
    • parseLoopTags($code) 分析处理模板代码中的循环结构(含子循环)标签,返回经过转换的代码
    • parseIfTags($code) 分析处理模板代码中的条件判断结构标签,返回经过转换的代码
    • parseVariableTags($code) 分析处理模板代码中的变量(含表达式)输出标签,返回经过转换的代码
    • parseHtmlTags($code) 分析处理模板代码中的特定html模板标签,返回经过转换的代码
    • parseBlockTags($code) 分析处理模板代码中的内容区块标签,返回经过转换的代码
    • isValidChar($x) 判断指定字符是否PHP变量名允许使用的字符

Yaf 使用说明

  1. 请复制 SpringView.php 类文件到项目 Yaf 框架 application.library 或 yaf.library 对应的类库目录下,默认设置一般都在 "application/library/" 下。

  2. Yaf 框架的插件目录(一般为"application/plugins/")下,创建一个初始化视图模板引擎的插件文件(比如叫 View.php),参考代码如下:

<?php
class ViewPlugin extends Yaf_Plugin_Abstract
{
    /**
     * 操作正式处理之前执行,初始化视图模板引擎
     * @return void
     */
    public function dispatchLoopStartup(Yaf_Request_Abstract $request, Yaf_Response_Abstract $response)
    {
         $viewPath = APPLICATION_PATH . '/views/'; //这里改为你的视图模板文件所在目录
         $viewCachePath = APPLICATION_PATH . '/cache/'; //这里改为你的视图模板缓存文件保存目录
         //为 Yaf 框架指定 SpringView 为视图处理引擎
         Yaf_Dispatcher::getInstance()->setView(new SpringView($viewPath, $viewCachePath)));
    }
}
  1. 配置完以上内容,就可以在 Yaf 框架控制器 Controller 下的方法( Action )中使用 SpringView 处理视图模板输出了,以下是代码举例:
<?php
class IndexController extends Yaf_Controller_Abstract
{
    /**
     * 默认首页
     */
    public function IndexAction()
    {
        //处理请求参数
        $request = $this->getRequest();
        $search  = array(
            'name'   => $request->getPost('name', ''),
            'status' => $request->getPost('status', STATUS_ALL),
        );
        //组装查询参数
        $params = $search + array(
            'search' => $search,
            'page' => 1,
            'rows' => 20,
        );
        //调用数据 model 查询数据
        $C = M::load('Customer');
        $result = $C->search($params);
        $params['total'] = $result['count'];
        $params['list']  = $result['data'];

        //最后将数据转给视图,输出内容
        $this->getView()->assign($params);

        //如果想将结果输出为Json,则
        $this->getView()->setJson(true);
    }
}
