本文实例讲述了ThinkPHP中Widget扩展的两种写法及调用方法。分享给大家供大家参考,具体如下:
Widget扩展一般用于页面组件的扩展,在页面根据需要输出不同的内容,下面介绍一下ThinkPHP中Widget的两种写法及调用
写法一:
25,'limit'=>5))}
* cid为分类id,limit为调用数量
*/
public function render($data) {
$Article = M('Article');
$articleMap["cid"] = $data["cid"];
$data["articleList"] = $Article->where($articleMap)->order('id desc')->limit($data["limit"])->select();
foreach ($articleList as $key => $value) {
if ($value["thumbnail"] == "") {
$data["articleList"][$key]["thumbnail"] = '/Public/Img/Common/noThumbnail.jpg';
}
}
return $this->renderFile('articleList',$data);
}
}
模板文件articleList.html在Lib/Widget/Article目录下
写法二:
5),'Widget')}
* cid为分类id,limit为调用数量
*/
public function articleList($cid,$limit) {
$Article = M('Article');
$articleMap["cid"] = $cid;
$data = $Article->where($articleMap)->order('id desc')->limit($limit)->select();
foreach ($data as $key => $value) {
if ($value["thumbnail"] == "") {
$data[$key]["thumbnail"] = '/Public/Img/Common/noThumbnail.jpg';
}
}
$this->assign('articleList',$data);
$this->display('Widget:articleList');
}
}
模板文件articleList.html,内容同写法一,但放在Tpl/风格名/Widget/目录下
如果模板文件放在ArticleWiget.class.php文件所在目录的Article文件夹下,则写法如下:
display(dirname(__FILE__) . '/Article/articleList.html');
