创建商品表
#商品表
CREATE TABLE IF NOT EXISTS `goods` (
`goods_id` int(10) unsigned NOT NULL AUTO_INCREMENT,

引入模板goodsadd.php
define("ACC", true);
require("../include/init.php");
include(ROOT.'view/admin/templates/goodsadd.html');
goodsaddAct.php
<?php
define("ACC", true);
require("../include/init.php");
$data = array();
$data["goods_name"] = trim($_POST['goods_name']);
if ($data['goods_name'] =='') {
exit('商品名称不能为空');
}
/*
进行数据的检验
*/
$data["goods_sn"] = trim($_POST['goods_sn']);
$data["cat_id"] = trim($_POST['cat_id']);
$data["shop_price"] = $_POST['shop_price'] ;
$data["goods_desc"] = trim($_POST['goods_desc']);
$data["goods_weight"] = $_POST['goods_weight']* $_POST['weight_unit'];

$goods = new GoodsModel();
if ($goods_id = $goods->add($data)) {
echo "商品发布成功";
}else{
echo "商品发布失败";
}
?>
GoodsModel.class.php
<?php
defined('ACC')||exit('ACC Deniec');

class GoodsModel extends Model{
protected $table = 'goods';
public function add($data){
return $this->db->autoExecute($this->table,$data);
}
}
?>
问题:
1 当字段多的时候,要逐一从$_POST里接受字段,比较麻烦
能否自动把$_POST里面合理的字段取出来。
即表中的列名对应$_POST字段
如goods_id,goods_name,goods_desc 则会自动把$_POST里的字段拿出来

把表里的字段都拿出来,不合理的不要

2 CatModel和 GoodsModel 里,都有一个add方法,重复了,
如何解决,再抽象一步

3 字段的合法性,也自动判断
