因为外键约束tb_product` (`product_id`))，你要保存的图片它所属的产品ID该条数据，在数据表中tb_product不存在报错。tb_product创建该条ⅠD记录即可。

需要 先在tb_product表格中添加数据 product_id 及 几个必须变量  含义为 定义新产品

有了新产品  然后在product_img表格中添加图片详情 匹配到商品中即可 

逻辑先理解了 就好了

同样的问题  product_id  是自动生成键  所以无法插入  不理解  老师最后定义的是

是不是主表的product是空表的原因呀？

  同学好，
  看错误应该是product_img里插入了一条在tb_product里不存在的product_id。。导致的错误

• 提问者 Che_ 回复 翔仔 #2
