html文件
php文件
require_once("conn.php");
$pictype=$_post['pictype'];
if($pictype=="")
{echo "没有填写种类";}
else
{
echo "添加种类成功";
}
?>
总是显示没有填写种类请问我哪里出错了？谢谢
回复讨论(解决方案)
==是大小和数值都相等，你试试把if($pictype=="")改成if(!$pictype)看下
是 $_POST['pictype'] 不是 $_post['pictype'];
$_POST大写
==是大小和数值都相等，你试试把if($pictype=="")改成if(!$pictype)看下
还是不行
