ORs within WHERE AND clause easier?

[palsypentertainment]

The following was my initial code:

$this->db->where( 'f.pendinglive', 1 );
$this->db->orWhere( 'f.statusshort', $status, 'IN' );

but now, I had to do the following to add an extra AND for f.date, as I'm not sure if the extra AND would have any diverse effects if adding it to the above:

$statusList = "'" . implode("','", $status) . "'";
$this->db->where( '( f.pendinglive = 1 OR f.statusshort IN ('.$statusList.') )' );
$this->db->where( "f.date >= DATE_SUB(UTC_TIMESTAMP(), INTERVAL 3 HOUR)" );

I just wanted to know if there's a way to nest an OR within a WHERE AND clause...... If not, it's fine, manually imploding arrays is just an extra step.

TIA.
