第二个选择查询不起作用

Question

无论如何都没有执行第二个查询。我尝试删除第一个查询并仅执行第二个查询但仍然。仅在选择查询时才会发生这种情况。

<?php
include 'connect.php';
$func=$_GET['func'];
if($func=="login")
{
    $u=$_POST['name'];
    $p=$_POST['pwd'];
    $query=mysqli_query($con,"select * from user where usr_id='$u' & usr_pwd='$p'");
    $row=mysqli_fetch_array($query);
    $query1=mysqli_query($con,"select * from usradmin where usr_id='$u' & usr_pwd='$p'");
    $row1=mysqli_fetch_array($query1);
   if($u==NULL || $p==NULL)
   {
       echo "Feilds Cennot Be Empty";
   }
   else
       {

    if($u==$row['usr_id'] && $p==$row['usr_pwd'])
    {
        echo "Login Success";
    }
    else if($u==$row1['usr_id'] && $p==$row1['usr_pwd'])
    {
        echo "Admin Login Success";
    }
    else
    {
        echo "Login Failed";
    }
   }
}
?>
