回复讨论(解决方案)

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;
看看

在62行上面 echo $conn->error; 看看



No database selected;没有选择数据库,不可能啊

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);


我数据库没有设置密码。。那个不用填 了

也没看到你include conn.php ,但包含了也没用,因为你是用mysqli。


那要怎么解决啊

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");



试过了,还是报同样的错。。

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);
