/**
 * Created by xx.
 * User: msi
 * Date: 2017/10/24

header("content-type:text/html; charset=utf-8");

//引入前面的DBDA方法集文件
require_once "../DBDA.class.php";
$db = new DBDA();
var_dump($_POST);
if(!empty($_POST)) {
    $uname = $_POST["uname"];
//查询用户注册的用户名是否和数据库已有的用户名重复，并返回查询结果；
    $sql = "select * from t_user WHERE uname = '{$uname}'";
//    echo $sql;
    $result = $db->strQuery($sql);

//}
    if ($result != "0") {
        exit("用户名字被占用");
    } else {
        $sql_insert = "insert into t_user(uname,pwod) VALUES ('{$_POST["uname"]}','{$_POST["pwod"]}')";
        echo $sql_insert;
        $result2 = $db->Query($sql_insert, 0);
        var_dump($result2);
    }
}
//echo "张三";
//echo $_POST['uname'];
//echo $_POST['pwod'];
?>
