This article mainly shares with you the code for adding data in ThinkPHP, hoping to help everyone.

<?php
//后台商品控制器
namespace Admin\Controller;
use Think\Controller;
//Controller父类:ThinkPHP/Library/Think/Controller.class.php
class GoodsController extends Controller{
    //添加商品。"add"是一个关键字,所以方法名不能是"add"。
    function tianjia(){
        $goods = D(&#39;Goods&#39;);
        //一、 关联数组方式添加数据
        $arr = array(
            &#39;goods_name&#39; => &#39;黑莓手机&#39;,   //关联数组下标goods_name必须与数据表中的字段对应,否则该字段会被过滤。
            &#39;goods_price&#39; => 3400,
            &#39;goods_number&#39; => 14,
            &#39;goods_weight&#39; => 104,
        );
        $z = $goods -> add($arr);   //返回值$z是添加成功记录的主键id值。
        dump($z);
        
        //二、 AR方式添加数据,通过Model属性值添加(其实属性并未定义)
        //以下是 “对象给本身不存在的成员属性赋值”与给私有属性赋值一致,其会调用魔术方法__set();,在__set()方法里边会把成员属性的值赋予给data成员,进而在add()方法里边实现数据的添加
        $goods -> goods_name = "小米手机";  //属性值goods_name必须与数据表中的字段对应,否则该字段会被过滤。
        $goods -> goods_price = "2900";
        $goods -> goods_weight = "109";
        $z = $goods -> add();
        echo $z;
        $this -> display();
    }   
}

GoodsController.class.php(Goods product controller):

<?php
//后台商品控制器
namespace Admin\Controller;
use Think\Controller;
//Controller父类:ThinkPHP/Library/Think/Controller.class.php
class GoodsController extends Controller{
    //添加商品
    function tianjia(){
        $goods = D(&#39;Goods&#39;);
        //两个逻辑:展示表单、收集表单信息
        if(!empty($_POST)){  //如果是点击了添加(提交)按钮(提交给自己本身的页面)。
            //收集表单信息
			//$z = $goods -> add($_POST);
            $data = $goods -> create(); //收集表单信息、非法字段过滤、表单自动验证、信息过滤处理(跨站脚本攻击)等等。
            $z = $goods -> add($data);
            if($z){
                //$this ->redirect (地址分组/控制器/操作方法, 参数数组, 间隔时间, 提示信息)
                $this ->redirect(&#39;showlist&#39;, array(), 2, &#39;添加商品成功!&#39;);   //地址showlist表示当前控制器下的showlist。
            }else{
                $this ->redirect(&#39;tianjia&#39;, array(), 2, &#39;添加商品失败!&#39;);
            }
        }else{
            $this -> display();//展示添加商品表单
        }
    }
