PHP反馈表单功能展示 
　PHP中获取表单数据是很简单的。当一个表单被发送后，表单中所包含的各个元素被赋上了相应的值，而这样就可以像引用一般变量一样使用了。 
<FORM name="myform" ACTION="process_form.php3" METHOD="POST"> 
<INPUT TYPE="TEXT" NAME="mytext" VALUE="Some Value"> 
</FORM> 

表单：form.php3 
<? 
include("include/common.inc"); 
$title = "Feedback"; 
include("include/header.inc"); 
?> 
<P> 
<FORM ACTION="sendfdbk.php3" METHOD="POST"> 
<INPUT TYPE="text" NAME="name" value="Your name" SIZE="20" MAXLENGTH="30"> 
<INPUT TYPE="text" MAXLENGTH="40" WIDTH="20" value="Your Email" NAME="email"> 
<BR> 
<TEXTAREA ROWS="7" COLS="40" NAME="comment"> 
Your feedback on my home page. 
</TEXTAREA> 
<BR> 
<INPUT TYPE="submit" VALUE="Send Feedback!"> 
</FORM> 
</P> 
<? 
include("include/footer.inc"); 
?> 

处理表单：sendfdbk.php3 
<? 
include("include/common.inc"); 
$title = "Feedback"; 
include("include/header.inc"); 
if ( $name == "" ) 
{ 
// 现在我很讨厌匿名的留言！ 
echo "Duh ? How come you are anonymous?"; 
} 
elseif ($name == "Your name") 
{ 
// 这个浏览者真是不想透露姓名啊！ 
echo "Hello ? <B>Your name</B> is supposed to be replaced with 
your actual name!</B>"; 
} 
else 
{ 
// 输出一段礼貌的感谢语 
echo " 
Hello, $name. 
<BR> 
Thank you for your feedback. It is greatly appreciated. 
<BR> 
Thanking you 
<BR>

$MyEmailLink 
"; 
// 最后mail出去 
mail($MyEmail, "Feedback."," 
Name : $name 
E-mail : $email 
Comment : $comment 
"); 
} 
include("include/footer.inc"); 
?>
