send users activation Email for the new accounts

[Yousef Altaf]

I have this code (it's a form which will sign up new users and send them an email to active they account).

<?php
        if(isset($_POST['submited'])) {
            $msg="";
 
            $RFname = clean_text($_POST['RFname']);
            $RLname = clean_text($_POST['RLname']);
            $USERname = clean_text($_POST['UserName']);
            $USERpassword = $_POST['UserPass'];
            $USERpassword2 = $_POST['UserPassConfirm'];
            $USERemail = $_POST['UserEmail'];
            $USERwebsite = $_POST['WebSite'];
            $hash = clean_text(md5(rand(0,1000)));
 
            if($USERpassword !== $USERpassword2) {
            $msg = "<span class='errorMessges'>Confirm passwords did not match</span>";
            }
 
            elseif($check=$db->query("select 1 from loginaccess where Email ='".$USERemail."'")){
            if(mysqli_num_rows($check) > 0 ) {
                $msg = "<span class='errorMessges'>This email already taken</span>";
            }
 
            elseif(empty($_SESSION['6_letters_code'] ) || strcasecmp($_SESSION['6_letters_code'], $_POST['6_letters_code']) != 0){
            $msg = "<span class='errorMessges'>Human code verification invalid</span>";
          }
 
            else{
                $putData = " insert into loginaccess (id, FUname, LUname, Uname, Pword, Email, Website, hash) value ('', '$RFname', '$RLname', '$USERname', '$USERpassword', '$USERemail', '$USERwebsite', '$hash')";
 
                $inputResult = $db -> query ($putData) or die ('$db->error');
 
                if ($inputResult){
                $msg = "<span class='successMessgaes'>You have been successfully registered</span>";
 
                // Send email to our user 
$to='$USERemail'; 
$subject ='Signup | Verification'; 
$message ='

                    }else{
                        $msg = "<span class='errorMessges'>There was an error please try again later</span>";
                    }
                }
            }

I just don't send any Emails when the user submit.
I think it should do,
any Idea will help here.

First you should check for the return value of the function mail()
(see: http://www.php.net/manual/en/function.mail.php)

If this returns FALSE, no mail is send.
If this returns TRUE, is something in the config of your mailserver.
