Just finished my platformer physics for my game. Thought I could help.
Not sure if the above way is most effective.

What I have is this:

Onground Boolean - onGround
Terminal velocity - tv
Jump power - jmp
Velocity vector (added to the position) - vel

1

if(/*colliding on y axis*/)
{
vel.y = 0;
}
else
// didn't collide on y axis, add velocity to position

onGround = (vel.y == 0);
if(/*no solid tile directly below*/)
onGround = false;

if(!onGround)
if(vel.y < tv)
vel.y++; // or -- depending on whether positive y is up or down.

if(jumping)
vel.y = jmp;


Okay, this code is not copied from mine so it may have a mistake, but you should find any possible mistake quickly.

There are some things that need to be polished with this, but do that according to your game.
