Anyway, Just keep your main line face to face with the enemy, countering every enemy move.
For example, we could slow them by missile fire (archers, horse archers are the best for this), then order the pikemen to switch to non-phalanx formation (so they could run and if the enemy engage them, they will suffer lower combat malus), and reform them, facing the new menace.
Meanwhile, the cavalry units and the "normal" infantries would control enemy moves until the pikemen have completed their reforming manoeuver.
Even if the enemy succesfully outflank them, the phalanxes will hold the line anyway thanks to their numbers for some minutes, and you can use your unengaged units to take the upper hand on another point of the battlefield.
