我可以让PHP邮件表单正常工作。问题是，我希望验证后的提交按钮不刷新整个页面，而只刷新内容div层。我研究过各种解决方案，但我对PHP还很陌生，所以我可能输入的代码不正确。工作页面可以在www.kaimeramedia.com/derek/Website上找到，然后点击联系链接。实际联系人页面代码为：
<form method="post" id="captcha_form" name="form1" action="mailform.php">
<br />
<table width="100%" border="0">
<tr><td rowspan="4" width="125">
</td>
<td>
<div id="Imprint3">Name:</div></td>
<td width="15">
</td><td><div id="Imprint3">All fields are required.</div></td>
<tr>
<td width="150">
<input type="text" id="name" name="name" maxlength="30" value="name" onfocus="if
(this.value==this.defaultValue) this.value='';"/></td>
<td rowspan="5" colspan="2">
<table>
<tr><td width="10"></td><td>
<div id="Imprint3">Message:</div></td></tr>
<tr><td width="10">
</td>
<td width="200"><textarea name="message" id="message"
rows="6" cols="25" value="Enter your message" onfocus="if
(this.value==this.defaultValue) this.value='';"/><?php echo "</tex" . "tarea>"; ?>
</td>
</tr>
<tr>
<td align="center" colspan="2">
<input name="submit" type="submit" value="Submit" />
<input type="button" name="reset_form" value="Reset" onclick="this.form.reset();">
</td></tr></table>
</td>
</tr>
<tr>
<td valign="top"><div id="Imprint3">Email:</div></td> </tr>
<td valign="top">
<input type="text" id="email" name="email" maxlength="100" value="you@email.com"
onfocus="if(this.value==this.defaultValue) this.value='';"/></td>
</tr> <tr>
<td width="15"></td>
<td align="center"> <div style="padding-bottom: 1em;">
<img src="captcha.php" /> <br />
<input type="text" name="userpass" value="input the above text here" onfocus="if
(this.value==this.defaultValue) this.value='';"></div></td></tr></table></form>
mailform.php文件如下：
<?PHP
session_start();
try{
$check = new check();
if(!isset($_REQUEST['email']))
throw new exception('You did not enter an email address.');
if(!isset($_REQUEST['message']))
throw new exception('You did not enter a message.');
if(!isset($_REQUEST['name']))
throw new exception('You did not enter a name');
$sender = $_REQUEST['email'];
$message = $_REQUEST['message'];
$name = $_REQUEST['name'];
$recipient = 'text@text.com';
$subject = 'Regarding Your Portfolio';
if($check->captcha('userpass') == FALSE)
throw new exception('Your captcha is incorrect.');
if($check->spam($sender) == FALSE)
throw new exception('Your email field contains spam.');
if($check->spam($name) == FALSE)
throw new exception('Your name field contains spam.');
if($check->length($sender, 10) == FALSE)
throw new exception('Your email field does not satisfy the minimum character
count.');
if($check->length($message, 8) == FALSE)
throw new exception('Your message field does not satisfy the minimum character
count.');
if($check->length($name, 3) == FALSE)
throw new exception('Your name field does not satisfy the minimum character count.');
mail($recipient, $subject, $message, "From: $name <$sender>" );
include'thankyou.php';
}catch (Exception $E){
die($E->getMessage());
}
class check{
function captcha($field){
if(isset($_REQUEST[$field])==FALSE){ return false; }
if($_SESSION['pass'] != $_REQUEST[$field]){ return false; }
return true;
}
function email($email){
if(!filter_var($email, FILTER_VALIDATE_EMAIL)){ return false;}
return true;
}
function spam($field){
if(eregi("to:",$field) || eregi("cc:",$field) || eregi("'r",$field) ||
eregi("'n",$field) || eregi("%0A",$field)){ return false; }
return true;
}
function length($field, $min){
if(strlen($field) < $min){ return false; }
return true;
}
}
?>
我已将接收电子邮件替换为text@text.com在这个页面上，但在我的网站上，这是我真正的电子邮件。另一位用户在让这个脚本正常运行方面帮了我很多忙，但我想知道是否可以让thankyou.php刷新到当前div层，而不刷新整个页面。我想编辑的行是：include 'thankyou.php';。如有任何帮助，不胜感激。
这在php中是不可能的。您必须使用JavaScript才能实现这一点。
您可以在不刷新页面的情况下发送电子邮件，并在div中加载文件。
使用，例如jQuery和$.ajax函数，它看起来像这样：
var msg; // defines variable "msg"
$('#button_ID').click(function(e){
e.preventDefault(); // this prevents the page from reloading (or default behavior, so the form submit)
msg = $('#input_field_ID').val(); // gets the value of the input field and saves it in variable "msg"
$.ajax({
type: 'POST',
url: '/sendmail.php',
data: {message : msg}, // posts variable "msg" as "message"
cache: false,
success: function(data) {
$("#yourdivID").load('/thankyou.php'); // loads a file in a div
},
error: function(xhr, ajaxOptions, thrownError){
alert('there was an error');
}
});
});
在本例中，您可以使用$_POST["message"] 在sendmail.php中获取消息
或者使用$.post并序列化整个表单：
$.post("/sendmail.php", $("#formID").serialize());
只是你可以看到如何处理这样的事情。
