What are the RAW on the following situations and rules:
Question 1: Your party is in a 5 ft. wide corridor, you enter combat, and go to charge an enemy down the corridor… but don’t realize (or can’t see that) your invisible wizard friend has moved in front of you (earlier in the initiative order). What happens by RAW?
My take on RAW: You can’t charge thru a friendly square, so, it appears your charge would suddenly stop, your action would end, and you’d be moved back to the last legal square.
Interestingly, if this is so, seems like just moving around as fast as you can is one of the easier ways to find an invisible opponent (as soon as the GM stops you from entering a square, you know what square he’s at, and your party can hit it with glitterdust or faerie fire; until the invisible opponent moves anyway)
I’d I had to rule it in a homebrew game - - I’d convert the charge into an unintentional “overrun” attempt, possibly knocking over the invisible opponent, and giving it a 50% miss chance (since overrun is an attack).
Question 2: you are fighting an enemy, and your invisible wizard ally wielding a staff sneaks up (using Stealth), and positions himself directly behind and opposite the enemy; do you and the wizard get the +2 flanking bonus if the wizard remains hidden and doesn’t actually attack?
My take on RAW: It appears you would get a flanking bonus against the enemy, as the conditions for flanking have been satisfied (even thou, logically, you shouldn’t as the enemy doesn’t know the wizard is there and shouldn’t be concerned / distracted)
If I had to rule it in a homebrew game - - I’d probably rule it not give the flanking bonus, unless the enemy had reason to be concerned with an invisible opponent behind him.

1. RAW, your charge stops and you'd provoke an AoO from the invisible creature for trying to enter its space/leave a threatened square.
2. RAW, what matters for flanking is that you have an ally is the relevant spot when you are making a melee attack. It seems strange, but the defender doesn't have to be aware of the other threat; the threat just has to be present.
