check.php

php模块设计。。。里面的模块很有学习价值

<?
	include("db_conn.php");
	include("db_func.php");

	// 检查登录名称及等级 BEGIN
	$qrystr = "SELECT * FROM member WHERE m_username ='$admuser' AND m_level = '1'";
	$res = db_query($qrystr);
	// 检查登录名称及等级 END

	if (db_num_rows($res)>0)
	{
		$row = db_fetch_array($res);
		if ($userpass == $row['m_userpass']) // 检查登录密码
		{
			session_start();

			// 将 admuser 变量注册成为 session
			session_register("admuser");

			echo "<script>";
			echo "alert(\"登录正确\");";
			echo "location.href = \"manage.php?del=0&lic=1\";";
			echo "</script>";
		}
		else
		{
			echo "<script>";
			echo "alert(\"账号或密码错误\");";
			echo "location.href = \"index.php\";";
			echo "</script>";
		}

	}
	else
	{
		echo "<script>";
		echo "alert(\"账号或密码错误\");";
		echo "location.href = \"index.php\";";
		echo "</script>";
	}
