4. 增加extensions/ueditor, 目录结构如下：
1. 下载Ueditor (http://ueditor.baidu.com/website/)
2. 解压后，放到新建的widget/ueditor目录下;
3. 可以看到ueditor下新建了Ueditor.php文件，作为widget的运行程序：

}} 然后在模板页调用，<?php $this->widget('ext.ueditor.Ueditor', array( 'getId'=>'UpHoleInfos_solutions', //输入框的ID号 'UEDITOR_HOME_URL'=>"/", 'options'=>'toolbars:[["fontfamily","fontsize","forecolor","bold","italic","strikethrough","|", "insertunorderedlist","insertorderedlist","blockquote","|", "link","unlink","highlightcode","|","undo","redo","source"]], wordCount:false, elementPathEnabled:false, imagePath:"/attachment/ueditor/", ', )); ?>其中options的toolbars属性设置工具栏上的功能和下拉框，该属性在editor_config.js文件中中可以查看：
若采用如下代码，则默认会展示全部的富文本编辑属性：
<?php $this->widget('application.widget.ueditor.Ueditor', array(‘getId’=>'UpHoleInfos_solutions', 'htmlOptions'=> array( 'name'=>'editor',//指定ueditor实例的名称,个页面有多个ueditor实例时使用 'config'=> array( 'initialFrameHeight'=>'400', 'initialFrameWidth'=>'80%', ), ) ) ); ?>
