如何确定单选框是否要被选中
需要从后台数据库中读取某值，通过该值来判断前台界面的单选框是否被选中，应该怎么写？网上找了些不能用啊。
求一段范例代码

这样是错的，求正解。
------解决方案--------------------
checked="checked"
------解决方案--------------------
<input type="radio" name="yes" value="yes" <?php if($open==1) echo "checked='checked'" ?>><br />
------解决方案--------------------
写法是没有错的
你把你的$open输出来看看 是不是1
------解决方案--------------------
楼上说的还是有可能的, 先确认$open 是否为1 . 按理说你的写法是没问题的.
不知道你的html 和 php 是否是分离的,如果是分离的, 你可以在 php程序里判断 声明变量接收 , 在页面里调用变量. 如果不是分离的那就继续用你的方法就可以了.
