1、網站系統開發須要掌握的技術javascript

PHP、.NET、HTML等編程語言中至少一種以及環境配置、腳本語言、數據庫鏈結等技術。php

2、課堂測試的源程序代碼html

HTML源代碼：java

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>登錄界面</title>
</head>mysql

<body>
<center>
<h1>請登陸</h1>
<br><br><br><br>
<form name="first" action="land2.php" method="post">
<table width="500" border="0" cellspacing="20" cellpadding="0">
<tr>
<td>用戶名：</td>
<td><input type="text" name="ures"></td>
</tr>
<tr>
<td>密碼：</td>
<td><input type="password" name="ps"></td>
</tr>
<tr>
</tr>
<tr>
<td colspan="3" align="center"><input type="submit" value="登陸"、>
<input type="reset" value="取消">

</tr>
</table>
</form>
<br><br><br>
</center>
</body>
</html>sql

PHP源代碼：數據庫

<body><?php
if($_POST['ures']=='')
{
echo "<script>alert('用戶名不能爲空');</script>";
echo "<script language='javascript'>";
echo " location='index1.html ';";
echo "</script>";
}
elseif($_POST['ps']=='')
{
echo "<script>alert('密碼不能爲空');</script>";
echo "<script language='javascript'>";
echo " location='index1.html ';";
echo "</script>";
}
error_reporting(E_ALL^E_NOTICE^E_WARNING^E_DEPRECATED);
mysql_connect('localhost','root','');
mysql_select_db('mysql');
mysql_query('SET NAMES utf8');
$sql="SELECT password FROM menber2 WHERE user='$_POST[ures]'";
$rs=mysql_query($sql);
$row=mysql_fetch_assoc($rs);
$r=$_POST['ures'];
if($row)
{
if($row['password']==md5($_POST['ps']))
{
echo "<script>alert('登錄成功');</script>";
}
else
{
echo "<script>alert('密碼錯誤');</script>";
echo "<script language='javascript'>";
echo " location='index1.html ';";
echo "</script>";
}
}
else
{
echo "<script>alert('用戶名不存在');</script>";
echo "<script language='javascript'>";
echo " location='index1.html ';";
echo "</script>";
