Is there a way to give say, innate spellcasting to a player and add those spells with a number of times per day to be used or are all items only with charges ?

if its only with charges, it really needs to have more options.
if it can be done, i will need to be given an explanation of how, because im lost.

i'm trying to give a player an item that gives him innate spell casting.

like he now is able to cast minor illusion as a cantrip, easy to do.
but he can cast mirror image 3 times per day. and mental prison 1 time per day.
how do i do the later ?

thanks for taking your time to answer folks.

EDIT:
anothe rthing that would be great, would be the ability to add say negative bonuses as we can already do, and see them disappear if say an ability is active. you know like what we can already do with feats and racials. but instead of being a check for determining if the ability has been used or not. it would be checked if the user do not have the minuses.

aka i have a magic object that gives the user the equivalent of slow as long as he didn't drained a creature. so the guy would have a check or use aside an ability called Drain Life. and if the guy has it checked is fine, if he has it unchecked he gains a bunch of minuses.
