This PHP function pulls a single field from a single record in the database once the MySQL connection has already been established:
function getField($field, $tbl_name, $condition = 1)
{
$result = mysql_query("SELECT $field FROM $tbl_name WHERE $condition");
return @mysql_result($result, 0);
}
$myValue = getField("fieldName","myTable","id = " . $uniqueID);
