【问题描述】：
我的帐户因垃圾邮件多次被暂停，我的主机提供商告诉我检查我的网站安全性。可能是我的表格不够安全。你认为这个表单可以用来发送垃圾邮件吗？
这是我的代码：
<script type="text/javascript">
$(document).ready(function () {
$('#form').ajaxForm({
beforeSubmit: validate
});
function validate(formData, jqForm, options) {
var name = $('input[name=name]').fieldValue();
var email = $('input[name=email]').fieldValue();
var company = $('input[name=company]').fieldValue();
var location = $('input[name=location]').fieldValue();
var phone = $('input[name=phone]').fieldValue();
var message = $('textarea[name=message]').fieldValue();
if (!name[0]) {
alert('Please enter your name');
return false;
}
if (!company[0]) {
alert('Please enter the name of your organization');
return false;
}
if (!email[0]) {
alert('Please enter your e-mail address');
return false;
}
if (!phone[0]) {
alert('Please enter your phone number');
return false;
}
if (!location[0]) {
alert('Please enter your location');
return false;
}
if (!message[0]) {
alert('Please enter your message');
return false;
}
else {
$("#form").fadeOut(1000, function () {
$(this).html("<img src='note.png' style='position: relative;margin: 0 auto;width: 500px;left: 20px;top: 30px;'/>").fadeIn(2000);
});
var message = $('textarea[name=message]').val('');
var name = $('input[name=name]').val('');
var email = $('input[name=email]').val('');
var phone = $('input[name=phone]').val('');
var company = $('input[name=company]').val('');
var location = $('input[name=location]').val('');
}
}
});
</script>
html:
<form id="form" method="post" name="form" action="send.php">
<input id="name" type="text" name="name"/>
<input id="company" type="text" name="company"/>
<input id="email" type="text" name="email"/>
<input id="phone" type="text" name="phone"/>
<input id="location" type="text" name="location"/>
<textarea name="message" id="message" rows="10"></textarea>
<input class="submit" type="submit" value="send" name="submit"></input>
</form>
php:
<?php
if($_POST){
$email = $_POST['email'];
$name = $_POST ['name'];
$company = $_POST ['company'];
$phone = $_POST ['phone'];
$location = $_POST ['location'];
$message = $_POST ['message'];
// response hash
$ajaxresponse = array('type'=>'', 'message'=>'');
try {
// do some sort of data validations, very simple example below
$all_fields = array('name', 'email', 'message');
filter_var($email, FILTER_VALIDATE_EMAIL);
foreach($all_fields as $field){
if(empty($_POST[$field])){
throw new Exception('Required field "'.ucfirst($field).'" missing input.');
}
}
// ok, if field validations are ok
// now Send Email, ect.
// let's assume everything is ok, setup successful response
$subject = "Someone has contacted you";
//get todays date
$todayis = date("l, F j, Y, g:i a") ;
$message = " $todayis \n
Attention: \n\n
Please see the message below: \n\n
Email Address: $email \n\n
Organization: $company \n\n
Phone: $phone \n\n
Location: $location \n\n
Name: $name \n\n
Message: $message \n\n
";
$from = "From: $email\r\n";
//put your email address here
mail("...@yahoo.com", $subject, $message, $from);
//prep json response
$ajaxresponse['type'] = 'success';
$ajaxresponse['message'] = 'Thank You! Will be in touch soon';
} catch(Exception $e){
$ajaxresponse['type'] = 'error';
$ajaxresponse['message'] = $e->getMessage();
}
// now we are ready to turn this hash into JSON
print json_encode($ajaxresponse);
exit;
}
?>
非常感谢！
