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:
<?php $this->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:
<?php $this->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 ≡"
),
)); ?>
