Its probably messed up inside your phone, the charging part, goto the store and get it looked at.

I would go to the apple store

Is your wall plugin work? Did any water get on your iPhone this problem happened to me I droped my I pod in the bath and would not work on charger but others. Is there another apple product in your home that you can test the charger out with or maybe you need to blow where you put the charger in your phone if can't find awnser go call apple support maybe there somewhere between your charger isn't connected
