How do i fix my wooden door frame, kicked in too?

You can buy a ready cut door framing at a timber yard or builders merchants - various widths....

And Frame fixing screws (drill a hole and hammer it in) from the same places or a DIY store...

Easier - if you can manage it and the damage is small - to saw out the damaged timber and glue in / slot in / screw in a suitable small piece to fit - a section - if you need to fill gaps then use a piece of timber and wedges.

Replace as little as possible - cheaper - quicker and easier.

Good luck...
