php 怎么输出复选框呢?
表单有6个复选框,如果选中的分别是第126个,数据库存为 1,2,6
现在的问题是 在修改的页面 怎么用php从数据库取值,输出6个复选框,让126为checked ?
回复讨论(解决方案)
$row['id']=1;
>
我的意思是 从数据库取到值 1,2,6 之后, 怎么输出6个复选框,让第126个默认选中,345个不选中,
难点在于中间插入不选中的

把你选出来的复选框(比如对应1,2, 6)所对应的checked 属性设置上就可以了啊。
如果你数据库存的是1,2,6,你可以直接把对应的复选框的名字或id也设置成对应的,然后就可以直接访问到需要改变状态的checkbox

做个if判断,等于1,2,6的就 checked, 不等的就不checked
