我的联系表格有这个问题。当我提交表格时,我的邮箱中收到了 2 封相同的电子邮件。
我使用 JS 检查表单是否有错误,然后使用简单的 PHP mail() 函数发送电子邮件。
这是PHP代码:
<?php
$from = Trim(stripslashes($_POST['email']));
$to = "myemail@gmail.com";
$subject = "Contact Form";
$name = Trim(stripslashes($_POST['name']));
$email = Trim(stripslashes($_POST['email']));
$number = Trim(stripslashes($_POST['number']));
$message = Trim(stripslashes($_POST['message']));
$body = "";
$body .= "Name: ";
$body .= $name;
$body .= "\n\n";
$body .= "E-mail: ";
$body .= $email;
$body .= "\n\n";
$body .= "Telephone Number: ";
$body .= $number;
$body .= "\n\n";
$body .= "Message: ";
$body .= $message;
$body .= "\n\n";
$success = mail($to, $subject, $body, "From: <$from>" . "\r\n" . "Reply-to: <$from>" . "\r\n" . "Content-type: text; charset=utf-8");
?>
这是JS:
$(".submit").click(function() {
var name = $("input[name=name]").val();
var email = $("input[name=email]").val();
var number = $("input[name=number]").val();
var message = $("textarea[name=message]").val();
if (defaults['name'] == name || name == "") {
$(".error").text("Please enter your name!");
return false;
} else if (defaults['email'] == email || email == "") {
$(".error").text("Please enter your email!");
return false;
} else if (defaults['number'] == number || number == "") {
$(".error").text("Please enter your number!");
return false;
} else if (defaults['message'] == message || message == "") {
$(".error").text("Plese enter your message!");
return false;
}
var dataString = 'name=' + name + '&email=' + email + '&number=' + number + '&message=' + message;
$(".error").text("Please wait...").hide().fadeIn("fast");
$.ajax({
type: "POST",
url: "contact.php",
data: dataString,
success: function() {
$('#form form').html("");
$('#form form').append("<div id='success'>Your message has been sent! Thank you</div>");
}
});
return false;
});
这是 HTML 表单:
<form id="contact" method="post" action="#">
<label for="name">Name:</label>
<input type="text" name="name" required tabindex="1">
<label for="email">Email adress:</label>
<input type="text" name="email" required tabindex="2">
<label for="number">Tel. number:</label>
<input type="text" name="number" tabindex="3">
<label for="message">Your message:</label>
<textarea name="message" rows="10" cols="70" required tabindex="4"></textarea>
<input type="checkbox" id="terms" name="terms" value="terms">I agree to the <a href="#">terms</a>
<input type="submit" name="submit" class="submit more-info" tabindex="5" value="Send">
<span class="error"></span>
</form>
我一直在为我的所有联系表格使用相同的代码,它工作正常。可能是托管/服务器相关问题吗?
