我想在相应字段下方显示错误消息,并在表单下方显示成功消息。我能够获得成功消息,但即使字段为空,我也不会显示错误消息。以下是我的代码:-
联系人.html
<!DOCTYPE html>

<head>
<link rel="stylesheet" media="screen" href="styles.css" >
<script type="text/javascript" src="my.js"></script>
<script src="http://code.jquery.com/jquery-latest.js"></script>
<script>
$(document).ready(function(){
$('#submit').click(function(e){
e.preventDefault();
$.post("send.php", $("#mycontactform").serialize(), function(response) {
$('#success').html(response);
//$('#success').hide('slow');
});
return false;
});
});
</script>
<script type="text/javascript">
function validateRoleForm() {
var name = document.getElementById('name').value;
if (name == "" || name == null) {
$('#errortext1').html('please enter name.');
return false;
}
else if{
var name = document.getElementById('email').value;
if (name == "" || name == null) {
$('#errortext2').html('please enter email.');
return false;
}
else if{
var name = document.getElementById('message').value;
if (name == "" || name == null) {
$('#errortext3').html('please enter message.');
return false;
}
else {
$('#success').html('Mail sent');
return true;
}
}
</script>
</head>

<?php
// Here we get all the information from the fields sent over by the form.
$name = $_POST['name'];

$subject = 'the subject';
$message = 'FROM: '.$name.' Email: '.$email.'Message: '.$message;
$headers = 'From: youremail@domain.com' . "\r\n";
$error = array(
"name" => "",
"email" => "",
"message" => ""
);
json_encode($error);
$email = ( isset( $_POST["email"] ) ) ? trim( $_POST["email"] ) : false;
$name = ( isset( $_POST["name"] ) ) ? trim( $_POST["name"] ) : false;
$message = ( isset( $_POST["message"] ) ) ? trim( $_POST["message"] ) : false;
if ( !$email ) {

}
if ( !$name ) {
$error["name"] = "Name is required!";
}
if ( !$message ) {
$error["message"] = "Message is required!";
}
else { // this line checks that we have a valid email address
mail($to, $subject, $message, $headers); //This method sends the mail.
echo "Your email was sent!"; // success message
}
?>
请帮帮我。我不知道我哪里出错了?
