Do poison or weapons with a special ability like flaming or frost still happen if they don't pass DR.
I would also like too see where this is said in a rule book if you can oblige.

If it deals damage no, I belive posion works though, check this site out will help www.d20pfsrd.com

Energy yes. There is no 'rule' on it because it does not prohibit it.
DR affects physical damage only. So, if you do not penetrate and you are doing energy damage the energy damage still goes through (barring energy resistance/immunity)

Poison, Im not sure about. I vaguely remember something which states that if there is a poison or disease effect that you actually have to hurt the creature first. However, I cannot remember the source so it could be my imagination. I will research it and get back to you.

Found it:

CRB p561 wrote:

Whenever damage reduction completely negates the damage from an attack, it also negates most special effects that accompany the attack, such as injury poison, a monk’s stunning, and injury-based disease. Damage reduction does not negate touch attacks, energy damage dealt along with an attack, or energy drains. Nor does it affect poisons or diseases delivered by inhalation, ingestion, or contact.

So if a flaming sword with poison on it fails to penetrate the DR the poison does not take effect but the fire does.

Thanks you guys were really helpful and i really appreciate it because i been trying too find a ruleing on it for the past hour at least so thanks again.

I'm not surprised, really. There is information on damage reduction in both CRB Glossary and the Universal Monster Rules of the Bestiary, and neither is complete without the other.
