提供两种方式的分类树格式，表格和下拉框形式的树形结构
可以自定义表格和下拉框的样式，自定义以哪一列的参数为格式化数据，自定义层级关系参数，自定义表格列名称，也可以设置时间的格式化。
调用方式
表格方式：
复制代码 代码如下:
widget('ext.tree.widgets.TreeWidget',array(
'dataProvider' => $dataProvider, // 传递数据
'pid' => 'pid', // 设置层级关系id
'tableClass' => 'items table table-striped table-bordered table-condensed', // 表格样式
'formatParam' => 'name', // 设置格式化字段
'formatTime' => array( // 设置格式化的时间参数
'created'
),
'tableHead' => array( // 设置表格列头信息
'分类ID',
'频道',
'中文名',
'英文名',
'首字母',
'排序',
'分类级别',
'父ID',
'创建时间',
),
)); ?>
下拉框方式
复制代码 代码如下:
widget('ext.tree.widgets.TreeWidget',array(
'dataProvider' => $cate, // 传递数据
'pid' => 'pid', // 设置父ID
'formatParam' => 'name', // 设置格式化字段
'treeType' => false, // 输出树格式
'selectClass' => 'class="span11"', // 设置下拉框样式
'defaultSelectValue' => array( // 设置下拉框的默认值和选项
0 , '≡ 作为一级栏目 ≡'
),
)); ?>
