Database Retrieval with php - php

Question

I'm creating a page where it gets contact details from the forum on registered members. I've hit a little problem trying to retrieve the custom fields. For University and flights a drop down menu is used so that users can select from a specific list. However the forum uses 3 different table to store the data.
This is a small part of the tables
db mock up http://www.emuas.co.uk/images/db_mock_up.png
at the moment I get the uni for the uni query and a flight for the flight query, but the result is unrelated to the user_id. Not sure how to change that though.
$user = "SELECT *
FROM profile_fields_data
JOIN users
ON profile_fields_data.user_id = users.user_id
ORDER BY users.username";
$uni = "SELECT *
FROM profile_fields_data
JOIN users
ON profile_fields_data.user_id = users.user_id
JOIN profile_fields_lang
ON profile_fields_data.pf_university = profile_fields_lang.option_id
WHERE field_id =4
ORDER BY users.username";
$flight = "SELECT *
FROM profile_fields_data
JOIN users
ON profile_fields_data.user_id = users.user_id
JOIN profile_fields_lang
ON profile_fields_data.pf_flight = profile_fields_lang.option_id
WHERE field_id =3
ORDER BY users.username";
$userdata = $db->sql_query($user);
$unidata = $db->sql_query($uni);
$flightdata = $db->sql_query($flight);
while($data = $db->sql_fetchrow($userdata))
{
$datauni = $db->sql_fetchrow($unidata);
$dataflight = $db->sql_fetchrow($flightdata);
echo "<tr>
<td> <a href='http://emuas.co.uk/forum/memberlist.php?mode=viewprofile&u=" . $data['user_id'] . "'>" . $data['username'] . "</a></td>
<td> <a href='mailto:" . $data['user_email'] . "'>" . $data['user_email'] . "</a> </td>
<td>" . $data['pf_contact_number'] . "</td>
<td>" . $data['user_birthday'] . "</td>
<td>" . $data['pf_service_number'] . "</td>
<td>" . $datauni['lang_value'] . "</td>
<td>" . $dataflight['lang_value'] . "</td>
<td>" . $data['pf_secondary_duty'] . "</td>
</tr>";
Many thanks

Found the problem. When the forum got the data for option_id it added 1 to the value. I;ve changed it to take this into account
