来大神,求解决啊
在62行上面 echo $conn->error; 看看
$sql=$conn->query("call admin_regs('".$admin_user."','".$admin_pass."')");
执行失败
echo $conn->error;

在62行上面 echo $conn->error; 看看
在62行上面 echo $conn->error; 看看
这是连接数据库文件conn.php
$id=mysql_connect("localhost","root");
mysql_select_db("db_wlgl",$id);
mysql_query("set names gb2312");
?>
$conn = new mysqli("localhost", "root", "", "db_wlgl);
也没看到你include conn.php ,但包含了也没用,因为你是用mysqli。
$conn = new mysqli("localhost", "root", "", "db_wlgl);

7楼大版的不就是吗
是吗?不填就是空串,但位置还是要占的
//你的$conn=new mysqli("localhost","root","db_wlgl);改成$conn=new mysqli("localhost","root","","db_wlgl");
//你的$conn=new mysqli("localhost","root","db_wlgl);改成$conn=new mysqli("localhost","root","","db_wlgl");
贴出你修改后的代码看看。
$sql=$conn->query("call admin_regs('".$admin_user."','".$admin_pass."')") or die($conn->error);
我的也是,这么解决请指导Fatal error: Call to a member function fetch_array() on a non-object in D:\xampp\htdocs\wlgl\index.php on line 62 $res=$sql->fetch_array(MYSQL_BOTH);
