Forgotten password page help [PHP/HTML] - php

Question

I have a CMS, I am creating a forgotten password page, the page will require a user to enter an email address and the code will find it in the database and send them an email, in my database, i have multiple users accounts assigned to one email address.
I want it so that if the user enters an email address and it was more than one account assigned to it, to error a message saying please contact your admin, but atm, it is not doing this. Any suggestions?
Here is my forgotten password page code:
if ($lookup) {
$user->sendPasswordResetEmail();
echo"sent email";
} elseif ($lookup) {
echo "please contact your admin";
}else{
$echo"Can't find user";
}
}
}else{
echo "please enter an email address";
}
}
I take the information from a different file, here is the snippet for the code where I take the database:
$resetsystem = $db->query($qry);
if ($resetsystem && $resetsystem->num_rows == 1) {
$that->setUserData($rs->fetch_assoc());
return true;
}
if ($resetsystem && $resetsystem->num_rows > 1) {
return;
}
return false;
}

update following code:
function lookupByEmail($userID) {
global $db;
$this->id = $userID; $qry = " SELECT user_id, user_first_name, user_last_name, user_username, user_email, user_suspended FROM cms_users WHERE user_email = " . $db->SQLString($this->id) . " AND user_deleted
= 0;";
$rs = $db->query($qry);
if ($rs && $rs->num_rows == 1) {
$this->setUserData($rs->fetch_assoc());
return 1;
}
if ($rs && $rs->num_rows > 1) {
return 2;
}
return 0;
}
and then where you are checking the $found variable do these updates
if ((int)$found == 1) {
$user->sendPasswordResetEmail();
$str_Message = '<div class="success_message">User found, an email has been dispatched to you.</div>';
} elseif ((int)$found > 1) {
$errors->defineError("too_many_users", "please contact your admin", array());
}else{
$errors->defineError("user_not_found", "The specified user could not be found. Please try again.", array());
}
