好的，这会有点啰嗦，我不确定它应该是 javascript 还是 php，我有一个联系表，如下所示：
<form action="contact.php" method="POST" id='contact_form'>
<p><label for="name">Name</label>
<input type='text' name='name' id='name' /></p>
<div class="clear"></div>
<p id='name_error' class='error'>Enter your name</p>
<p><label for="email">Email</label>
<input type='text' name='email' id='email' /></p>
<div class="clear"></div>
<p id='email_error' class='error'>Enter a valid email address</p>
<p><label for="telephone">Telephone</label>
<input type='text' name='telephone' id='telephone' /></p>
<div class="clear"></div>
<p id='subject_error' class='error'>Enter your telephone number</p>
<p><label for="message">Details</label>
<textarea name='message' id='message' rows="30" cols="30"></textarea></p>
<div class="clear"></div>
<p id='message_error' class='error'>Enter your message</p>
<p id='mail_success' class='success'>Thank you. We will be in contact soon.</p>
<p id='mail_fail' class='error'>Sorry, an error has occured. Please try again later.</p>
<div id="button">
<input type='submit' id='send_message' class="button" value='Submit' />
</div>
</form>
Javascript：
$(document).ready(function(){
$('#send_message').click(function(e){
//stop the form from being submitted
e.preventDefault();
/* declare the variables, var error is the variable that we use on the end
to determine if there was an error or not */
var error = false;
var name = $('#name').val();
var email = $('#email').val();
var telephone = $('#telephone').val();
var message = $('#message').val();
if(name.length == 0){
var error = true;
$('#name_error').fadeIn(500);
}else{
$('#name_error').fadeOut(500);
}
if(email.length == 0 || email.indexOf('@') == '-1'){
var error = true;
$('#email_error').fadeIn(500);
}else{
$('#email_error').fadeOut(500);
}
if(telephone.length == 0){
var error = true;
$('#subject_error').fadeIn(500);
}else{
$('#subject_error').fadeOut(500);
}
if(message.length == 0){
var error = true;
$('#message_error').fadeIn(500);
}else{
$('#message_error').fadeOut(500);
}
//now when the validation is done we check if the error variable is false (no errors)
if(error == false){
//disable the submit button to avoid spamming
//and change the button text to Sending...
$('#send_message').attr({'disabled' : 'true', 'value' : 'Sending...' });
//we submit it to contact.asp
$.post("contact.php", $("#contact_form").serialize(),function(result){
//and after the ajax request ends we check the text returned
if($.trim(result) == 'sent'){
$('#button').remove();
$('#mail_fail').fadeOut(500);
$('#mail_success').fadeIn(500);
}else{
//show the mail failed div
$('#mail_fail').fadeIn(500);
//reenable the submit button by removing attribute disabled and change the text back to Send The Message
$('#send_message').removeAttr('disabled').attr('value', 'Submit');
}
});
}
});
});
和 PHP：
<?php
$EmailFrom = Trim(stripslashes($_POST['email']));
$EmailTo = "joe@bloggs.com";
$Subject = "Contact Form Message";
$name = Trim(stripslashes($_POST['name']));
$email = Trim(stripslashes($_POST['email']));
$telephone = Trim(stripslashes($_POST['telephone']));
$message = Trim(stripslashes($_POST['message']));
$validationOK=true;
if (Trim($name)=="") $validationOK=false;
if (Trim($email)=="") $validationOK=false;
if (Trim($telephone)=="") $validationOK=false;
if (Trim($message)=="") $validationOK=false;
if (!$validationOK) {
print "failed";
exit;
}
$Body = "";
$Body .= "name: ";
$Body .= $name;
$Body .= "\n";
$Body .= "email: ";
$Body .= $email;
$Body .= "\n";
$Body .= "telephone: ";
$Body .= $telephone;
$Body .= "\n";
$Body .= "message: ";
$Body .= $message;
$Body .= "\n";
$success = mail($EmailTo, $Subject, $Body, "From: <$email>");
if ($success){
print "sent";
}
else{
print "failed";
}
?>
填写完毕后，我收到“抱歉，出现错误。请稍后再试。” 消息，但看不到我哪里出错了？
提前感谢您的帮助。
