这个if或者如果是联系方式

Question

dunno can I write one more question about contact form but i will try :) Maybe u will help faster ;p

Code:

<?php
 $name = $_POST['name'];
 $email = $_POST['email'];
 $message = $_POST['message'];
 $from = 'From: domain.com'; 
 $to = '[e-mail]'; 
 $subject = 'Message from domain.com';

 $body = "From: $name
 E-Mail: $email
 Message:
 $message";

   if ($_POST['submit']) {
    if (!preg_match("/([\w\-]+\@[\w\-]+\.[\w\-]+)/",$email))
        {
               echo '<p class="msg">Wrong email adress!!!</p>';
        }            

        if ($name != '' && $email != '') {               
                if (mail ($to, $subject, $body, $from)) { 
                        echo '<p class="msg">Your message has been sent!</p>';
                } else { 
                        echo '<p class="msg">Something went wrong, go back and try again!</p>'; 
                       } 
                } else {
                        echo '<p class="msg">You need to fill in all required fields!!</p>';
                       }
    }
?>  

And as u can see i have here few messages (echos) in if statements. But I wanna make this to display just one echo even if there would be more errors in contact form... Is that possible ?

example: Somebody leave all inputs empty and click "send" - atm he would get msg about wrong email and "u need fill all required fields". But in this kind os situation firstly i would like to display just msg about empty fields and after that if for example somebody would write wrong email another msg about wrong email :D Hope u understand what I mean. Thanks

if ($_POST['submit']) {

    if (!$email) {
        echo '<p class="msg">Email is required.</p>';
    }
    elseif (!$name) {
        echo '<p class="msg">Name is required.</p>';
    }
    elseif (!preg_match("/([\w\-]+\@[\w\-]+\.[\w\-]+)/",$email)) {
        echo '<p class="msg">Wrong email adress!!!</p>';
    }
    elseif ($name != '' && $email != '') {

        if (mail ($to, $subject, $body, $from)) { 
            echo '<p class="msg">Your message has been sent!</p>';
        }
        else { 
            echo '<p class="msg">Something went wrong, go back and try again!</p>'; 
        } 
    }
    else {
        echo '<p class="msg">You need to fill in all required fields!!</p>';
    }

}
