一代码

conn.php

<?php$conn = mysql_connect("localhost","root","root") or die("数据库错误".mysql_error());mysql_select_db("db_database21",$conn) or die("数据库错误".mysql_error());mysql_query("set names gb2312");?>

index.php

<html xmlns="http://www.w3.org/1999/xhtml"><head><meta http-equiv="Content-Type" content="text/html; charset=gb2312" /><title>使用md5对用户注册密码进行加密</title><style type="text/css"><!--body,td,th {font-size: 12px;}body {margin-left: 10px;margin-top: 10px;margin-right: 10px;margin-bottom: 10px;}.STYLE1 {font-size: 14px;font-weight: bold;}--></style></head><body><table width="777" height="587" border="0" align="center" cellpadding="0" cellspacing="0" background="images/bg.jpg">  <tr>    <td width="149" height="200">&nbsp;</td>    <td width="448">&nbsp;</td>    <td width="158">&nbsp;</td>  </tr>  <tr>    <td height="187">&nbsp;</td>    <td align="center" valign="middle">  <form id="form1" name="form1" method="post" action="index_ok.php">    <table height="160" border="0" cellpadding="0" cellspacing="0">      <tr><td width="83" height="30" align="right" valign="middle" scope="col"><span class="STYLE1">用户名：</span></td>        <td width="267" height="30" align="left" valign="middle" scope="col"><label for="textfield"></label>        <input name="username" type="text" id="username" size="24" /></td>        <td width="25" align="center" valign="middle" scope="col">&nbsp;</td>      </tr>      <tr>        <td height="30" align="right" valign="middle" class="STYLE1" scope="col">密码：</td>        <td height="30" align="left" valign="middle" scope="col"><input name="password" type="password" id="password" size="25" /></td>        <td align="center" valign="middle" scope="col">&nbsp;</td>      </tr>      <tr>        <td height="30" align="right" valign="middle" class="STYLE1" scope="col">地址：</td>        <td height="30" align="left" valign="middle" scope="col"><input name="address" type="text" id="address" size="35" /></td>        <td align="center" valign="middle" scope="col">&nbsp;</td>      </tr>      <tr>        <td height="30" align="right" valign="middle" class="STYLE1" scope="col">电话：</td>        <td height="30" align="left" valign="middle" scope="col"><input name="tel" type="text" id="tel" size="20" /></td>        <td align="center" valign="middle" scope="col">&nbsp;</td>      </tr>      <tr>        <td height="40" colspan="3" align="center" valign="middle" scope="col"><input type="image" name="imageField" src="images/bg2.JPG" />                    &nbsp;&nbsp;<input type="image" name="imageField2" src="images/bg1.JPG" onclick="form.reset();return false;" /></td>        </tr>    </table>  </form>  </td>    <td>&nbsp;</td>  </tr>  <tr>    <td height="200">&nbsp;</td>    <td>&nbsp;</td>    <td>&nbsp;</td>  </tr></table></body></html>

index_ok.php

<?php include("conn/conn.php");if(trim($_POST[username])!= "" and trim($_POST[password])!= "" and trim($_POST[tel])!=""){$pwd = md5($_POST[password]);$sql = "insert into tb_user(username,password,address,explains)values('".$_POST[username]."','".$pwd."','".$_POST[address]."','".$_POST[tel]."')";$result = mysql_query($sql,$conn);if($result){echo "<font color='red'>注册成功。</font>";}else{echo "<font color='green'>注册失败!</font>";}}else{echo "请认真填写用户名和密码！";}?>
