ThinkPHP Widget模块开发流程

初识ThinkPHP的Widget，现把模块开发的流程发布如下，也方便以后自己查阅：

一、新建数据库表self_modules,sql代码如下

CREATE TABLE `self_modules` (

  `id` int(11) unsigned NOT NULL AUTO_INCREMENT,

  `title` text NOT NULL,

  `content` text NOT NULL,

  `order` int(11) NOT NULL DEFAULT '',

  `position` varchar(50) NOT NULL,

  `published` tinyint(1) NOT NULL DEFAULT '',

  `module` varchar(50) NOT NULL,

  `access` tinyint(3) NOT NULL DEFAULT '',

  `showtitle` tinyint(3) NOT NULL DEFAULT '',

  `params` text NOT NULL,

  PRIMARY KEY (`id`)

) ENGINE=MyISAM AUTO_INCREMENT=7 DEFAULT CHARSET=utf8;

INSERT INTO `self_modules` VALUES ('', '主菜单', '', '', 'left', '', 'Menu', '', '', 'id=1\nstyle=17joys');

INSERT INTO `self_modules` VALUES ('', '子菜单', '', '', 'left', '', 'Menu', '', '', 'id=1\nstyle=menu');

INSERT INTO `self_modules` VALUES ('', '最新文章模块', '', '''left','','LatestNews','','','sid=2\ncid=3\nstyle=latestnews');

2、前台项目home/Lib/Action目录下建立ModulesAction.class.php,代码如下

class ModulesAction extends CommonAction{

    function index(){

        $mod = new Model('Modules');

        $list = $mod->where("position='left'")->select();

        $this->assign('modlist',$list);

        $this->display();

    }

}

3、/home/Tpl/default/Modules目录下建立index.html模板文件，代码如下(注意模块的调用方法)

<!doctype html>

<html>

<head>

<meta charset="utf-8">

<title>模块</title>

</head>

<body>

<volist name="modlist" id="row">

    <h3>{$row['title']}</h3>

    {:W($row['module'],array('params'=>$row['params'],))}

</volist>

</body>

</html>

4、/home/Lib目录下建立Widget目录，在该目录下建立菜单模板文件MenuWidget.class.php，代码如下

class MenuWidget extends Widget{

    function render($data){

        //return '<font color="'.$data['color'].'">aaa</font>';

        $params = $data['params'];

        $p = explode("\n",$params);

        $pv = array();

        foreach($p as $v){

            $tmp = explode("=",$v);

            $pv[$tmp[0]] = $tmp[1];

        }

        //dump($pv);

        $menuitem = new Model('MenuItem');

        $list = $menuitem->field("id,name,link,concat(path,'-',id) as bpath")->order('bpath,id')->where('menuid='.$pv['id'])->select();

        foreach($list as $key=>$val){

            $list[$key]['signnum'] = count(explode('-',$val['bpath']))-1;

            $list[$key]['marginnum'] = (count(explode('-',$val['bpath']))-1)*10;

        }

        $data['milist'] = $list;

        $content = $this->renderFile($pv['style'],$data);

        return $content;

    }

}

5、/home/Lib/Widget/目录下建立菜单模块的模板目录Menu，并在该目录下建立菜单模块模板menu.html和17joys.html（这里建两个主要是多套模板可以选择）代码分别如下：

menu.html

<ul>

    <volist name="milist" id="row">

        <li style="margin-left:{$row['marginnum']}px"><a href="{$row['link']}">{$row['name']}</a></li>

    </volist>

</ul>

17joys.html

<ol>

    <volist name="milist" id="row">

        <li style="margin-left:{$row['marginnum']}px"><a href="{$row['link']}">{$row['name']}</a></li>

    </volist>

</ol>

至此模块开发完成，下面再写一个最新文章模块可以用来练习使用：

1、/home/Lib/Widget/目录下建立最新文章模块的Widget文件LatestNewsWidget.class.php，代码如下

class LatestNewsWidget extends Widget{

    function render($data){

        $params = $data['params'];

        $p = explode("\n",$params);

        $pv = array();

        foreach($p as $v){

            $tmp = explode("=",$v);

            $pv[$tmp[0]] = $tmp[1];

        }

        $article = new Model('Article');

        $list = $article->where('sectionid='.$pv['sid'].' and catid='.$pv['cid'])->select();

        //dump($list);

        $data['alist'] = $list;

        $content = $this->renderFile('latestnews',$data);

        return $content;

    }

}

2、/home/Lib/Widget/目录下建立最新文章的模板目录LatestNews，并在该目录下建立最新文章模块的模板文件latestnews.html，代码如下：

<ul>

    <volist name="alist" id="row">

        <li>{:U('Article/view/id/'.$row['id'])}<a href="__APP__/Articl/view/id/{$row['id']}">{$row['title']}</a></li>

    </volist>

</ul>

至此最新文章模块完成，其实感觉也挺简单的，就两部，关键点就是处理好控制器模板穿过来的参数：{:W($row['module'],array('params'=>$row['params'],))}

文章的静态化要在home项目的配置文件配置静态化设置：/home/Conf/config.php

'URL_HTML_SUFFIX'=>'.html',
