yii框架分類樹擴(kuò)展示例
介紹了yii框架分類樹擴(kuò)展示例,提供兩種方式的分類樹格式，表格和下拉框形式的樹形結(jié)構(gòu),需要的朋友可以參考下.
提供兩種方式的分類樹格式，表格和下拉框形式的樹形結(jié)構(gòu)
可以自定義表格和下拉框的樣式，自定義以哪一列的參數(shù)為格式化數(shù)據(jù)，自定義層級(jí)關(guān)系參數(shù)，自定義表格列名稱，也可以設(shè)置時(shí)間的格式化。
調(diào)用方式
表格方式：
復(fù)制代碼 代碼如下:
<?php $this->widget('ext.tree.widgets.TreeWidget',array(
'dataProvider' => $dataProvider, /pic/p>
'pid' => 'pid', /pic/p>
'tableClass' => 'items table table-striped table-bordered table-condensed', /pic/p>
'formatParam' => 'name', /pic/p>
'formatTime' => array( /pic/p>
'created'
),
'tableHead' => array( /pic/p>
'分類ID',
'頻道',
'中文名',
'英文名',
'首字母',
'排序',
'分類級(jí)別',
'父ID',
'創(chuàng)建時(shí)間',
),
)); ?>
下拉框方式
復(fù)制代碼 代碼如下:
<?php $this->widget('ext.tree.widgets.TreeWidget',array(
'dataProvider' => $cate, /pic/p>
'pid' => 'pid', /pic/p>
'formatParam' => 'name', /pic/p>
'treeType' => false, /pic/p>
'selectClass' => 'class="span11"', /pic/p>
'defaultSelectValue' => array( /pic/p>
0 , '≡ 作為一級(jí)欄目 ≡'
),
)); ?>
