商品分类删除
1、删除商品时，根据商品id删除扩展分类表数据
商品扩展分类修改
1、在控制器GoodsController.class.php/edit()中根据商品id取出对应的所有扩展分类
2、在修改页面edit.html中显示对应扩展分类foreach，类似添加页面
注：考虑当没有扩展分类时的显示，使用if($gcData)
3、在模型类GoodsModel.class.php/_before_update()中处理扩展分类，先删除原数据，再插入新数据【多对多时，通常的用法】
<?php namespace AdminModel; use ThinkModel; class GoodsModel extends Model { //添加调用create方法允许接收的字段 protected $insertFields = 'goods_name,market_price,shop_price,is_on_sale,goods_desc,brand_id,cat_id';

//钩子方法_before_insert:添加前插入，在添加前会自动调用 //第一个参数：表单中即将要被插入数据库中的数据=>数组 //&按引用传递：函数外部的变量的值要在函数内部修改的话，必须按引用传递，除非传递的为对象，因为对象默认按引用传递 protected function _before_insert(&$data, $option) { $id = $option['where']['id'];
