PHP获取$_GET[gsid]值问题

$numdog获取不到$_GET[gsid]的值，总是等于初始化的1，如果你不初始化，它还报错，说未定义的变量。求大神指导，是编辑页面的取值问题。

回复讨论(解决方案)

你的表单是怎么写的？

有必要在代码最前面输出一下看看，到底页面提交了些啥。

print_r( $_GET);
print_r( $_POST);

如果不想看到错误提示，就在最前面加上
error_reporting(E_ALL ^ E_NOTICE);

代码没有问题，取不到这个gsid，是不是你是POST传来的，
你看这样可以取到值吗。
$_REQUEST['gsid']
另外，如果gsid是数字的话建议用intval($_REQUEST['gsid'])处理一下。

找到错误了，原来在表单上也要加入参数比如action="dogdo.php?id=5".感谢大家的热情讨论！
