I have a table with 2 fields: id_from and id_to.
I want to interogate the database and to display the results if the
id_to is equal to some current id OR id_from id_from is equla to saame
current id.
I use this but doesn't work
$sql = "SELECT id_from, id_to FROM ids WHERE id_from ='$current_id' OR
id_to='$current_id' ";
$result = mysql_query($sql);

This looks OK, but you may want to add parentheses
$sql = "SELECT id_from, id_to FROM ids WHERE (id_from ='$current_id'
OR id_to='$current_id') ";
