用php与mysql的电子贺卡程序

第一步：首先作一个如下面的表单：（注：这个表单里加了php程序）
<form method="post" action="mailtocard.php" name="card" onSubmit="return card_Validator(this)">
<table width="450" border="0" cellspacing="0" cellpadding="0" align="center">
<tr>
<td valign="top" width="143">
<input type="radio" name="inout" value="newyear" checked>
<img src="/images/newyear1.gif" width="75" height="75"> </td>
<td width="170">
<input type="radio" name="inout" value="newyear2_2">
<img src="/images/newyear2.gif" width="75" height="75"> </td>
<td width="137">
<input type="radio" name="inout" value="newyear3_3">
<img src="/images/newyear1.gif" width="75" height="75"> </td>
</tr>
<tr>
<td valign="top" colspan="3">
<textarea name="text" rows="7" cols="60" wrap="VIRTUAL">你好朋友：
</textarea>
</td>
</tr>
<tr>
<td valign="top" colspan="3">
<select name="music">
<option selected>--卡片背景音乐--</option>
<option value="101marry.mid">一千零一夜</option>
<option value="canyon.mid">canyon</option>
</select>
<input onclick=playSound() type=button value="试听音乐">
</td>
</tr>
<tr>
<td valign="top" colspan="3"> </td>
</tr>
<tr>
<td valign="top" colspan="3">
<table width="370" border="0" cellspacing="0" cellpadding="0" align="center" class="p11">
<tr>
<td width="108">

<?

if (strlen($g_username) > 1)
{
//判断是否登陆，若已登陆显示姓名及Email,不用填写。
$db=mysql_connect("localhost","root","");
$result=mysql_db_query("数据库名","select email,http from 数据库表名 where username=$g_username");

$row=mysql_fetch_array($result);
$bbs_email=$row[email];

echo "<div align=left>您的姓名：</div>
</td>
<td width=342>
$g_username
<input type=hidden name=username value=$g_username>
</td>
</tr>
<tr>
<td width=108>
<div align=hidden>您的Email：</div>
</td>

$bbs_email
<input type=hidden name=email value=$bbs_email>

";
}
//if (strlen($g_username) < 0)
else //判断没有登陆，需要填写姓名及Email。
{
echo "<div align=left>您的姓名：</div>
</td>
<td width=342>

<input type=text name=username>
</td>
</tr>
<tr>
<td width=108>
<div align=left>您的Email：</div>
</td>
<td width=342>

<input type=text name=email>";
}
?>
</td>
</tr>
<tr>

<td width="108">

<td width="108"> </td>
<td width="342">

<input type="button" name="submit" value="预览" onclick="preview()">
<input type="submit" name="submit" value="发送">
<input type="reset" name="Submit3" value="重来">
第二步：预览
<?

if (submit=="预览")
{
switch($new)
{
case "newyear":

$new="newyear.gif";
break;

case "newyear2_2":

$query=newyear2_2.gif;
break;

case "newyear3_3":
$query=newyear3_3.gif;

}
}
?>

$fileno .=$roundno.".html";
$fileurl = $dataurl."/".$fileno; //存放产生的贺卡的URL

$subject="朋友给你邮的贺卡";
$content = eregi_replace("<br>"," ","$text");

$t_body .= "************************************** ";
$t_body .= $f_name." 您好: ";
$t_body .= $g_username." 从http://lyjrich.oso.com.cn 寄了一张贺卡给你。 ";

mail($f_email,$subject,$t_body,"From: ".$email." ");

echo "<script language="javascript">history.back();alert("发送成功，谢谢使用！！");</script>";
