For future knowledge, it sounds as if either the "bar" in the port got bent or there's dirt in the port. If you look into the port in a strong light with a good magnifier, you can usually see the problem and fix it with a needle. Once you;ve done one, it takes about 60 seconds to fix one.
(You may also get an indication that the phone is charging when it's not plugged in with this problem.)
