In order for your mysql query

$result = 'SELECT * FROM records WHERE ' . implode(' AND ', $where);

To work you need to actually send it.

mysql_query($result)

What you have currently

while($row = @ mysql_fetch_array($result)) {

Is designed to be run on the result of a msql_query call. eg

$query= mysql_query($result);

then run

while($row = @ mysql_fetch_array($query)) {

So thats your only problem as far as i can see, you have just left out the query.

Hope that helps, feel free to ask for more details.
