see your point, but I thought those were the rules. why can a fighter attack his opponent twice while riding and can I attack onlyonce from one position. But oh well
Well actually a fighter can't really do that too - archer's can always (always!) make a full attack from horseback, because the horses movement is seperate from the rider.
A Ride By Attack is only one (one!) attack - using the Mounted Archery feat in conjuction with a ful move of your horse allows you to let your horse make a run (4x movement) and still allow you to get a full attack (actually, you can do that without the feat too, you'll just get lots of penalties to your attack rolls). On the plains, a mounted archer rocks. In the forest however, he shouldn't.
That is besides the point however, since a cavalier with lance could make his charge (with hefty damage bonusses), but that does
not allow his horse to attack yet - it has alreay moved. It is only when a warhorse is in melee that the warhorse and the rider together can make a lot of attacks.
Perhaps I have allowed previously (when my rules knowledge was not as it is now) for a rider to let his horse make a move and a full attack, I can't remember, but I assure you I would not do so again. The suggestion given for mounted combat is either that you give the mount an initiative and let the owner of the mount perform the actions of the mount at it's own initiative (usually involving a delay action), or simultaneously - which is what I prefer, since that is most "realistic".
And again, I am not taking away your ability to make full attack actions, au contraire, I am simply not granting you the ability to shoot through solid matter
So I take it you are making one attack
after moving 25 feet ahead?
