关于PHP向MYSQL插入图片地址字符串的问题,请大家详解

最近看了一下shopex,ecshop的mysql数据库设计

字段是goods_img varchar(255)按说这样只能插入255个字符,我当时有有点纳闷这用PHP插入数据图片地

址‘images/200905/goods_img/1_G_1240902890755.jpg(这个地址是直接从他们数据库中复印出来的地址我用的是phpmyadmin后

面的数据都是。。。省略了只能复印和看第一个图片地址)’,按字符计符计算的话连接插入数据超入数据6条 就会出错,但是在他们的后台可添加好

多的图片,这是怎么回事 ,难道 是mysql数据库会自动为这个字段重新改变类型???


请大家解解我的疑惑??


------解决方案--------------------
另外建一张表存放图片信息,每条记录一张图片,给出一个字段对应商品的id,这样就能在一个商品下面添加任意多张图片了
------解决方案--------------------
5.0.3以下的mysql 是 255之后的版本varchar最大65535个字节,不同字符集存储的个数并不固定.
------解决方案--------------------
第一次碰到,学习……
我一般用varchar没出过问题,还有mediumtext类型可以存放大数据
------解决方案--------------------
添加图片页面肯定做了限制,最多添加多少个图片。
