_ios of the example of Yii frame classification tree expansion

Provides two ways of classifying tree format, table and dropdown frame form tree structure
You can customize the style of the table and Drop-down boxes, customize which column parameters are formatted data, customize the hierarchy relationship parameters, customize the table column names, or set the formatting of the time.

Call mode

Table mode:

Copy Code code as follows:

<?php $this->widget (' Ext.tree.widgets.TreeWidget ', Array (


' Dataprovider ' => $dataProvider,//Pass data


' PID ' => ' pid ',//set level relationship ID


' Tableclass ' => ' items table table-striped table-bordered table-condensed ',//table style


' Formatparam ' => ' name ',//Set format field


' Formattime ' => Array (//Set time parameters for formatting)


' Created '


),


' Tablehead ' => Array (//Set table column header information


' Category ID ',


' Channel ',


' Chinese name ',


' English name ',


' First letter ',


' Sort ',


' Classification level ',


' Parent ID ',


' Creation time ',


),


));?>

Drop-down Box mode

Copy Code code as follows:

<?php $this->widget (' Ext.tree.widgets.TreeWidget ', Array (


' Dataprovider ' => $cate,//Pass data


' PID ' => ' pid ',//Set Parent ID


' Formatparam ' => ' name ',//Set format field


' Treetype ' => false,//output Tree format


' Selectclass ' => ' class= ' span11 ',//Set dropdown box style


' Defaultselectvalue ' => Array (//Set default values and options for drop-down boxes)


0, ' chess as a first-class column '


),


));?>
