Lets Play Cards.. Help figuring out what is in your hand

webdevdea · June 25, 2013

Ok so I have only one suit of cards say Ace through King,

I am creating a game like five card draw, and the user clicks the checkbox to choose the cards that he keeps, and then you get another deal, my problem is trying to figure out what the hand is this is what I have came up with thus far, Its generating the images and everything works except the part that scores the hand.. Help please

Way too hard to decipher not knowing what your whole app looks like. How about telling us what section is not right and what you ARE getting that is wrong?

Yeah, I agree with ginerjm. But, to answer your question in a general sense, I would use session data to store the cards. Whenever there is a shuffle, create all the cards as part of the "deck" in an array in the session. Then, when cards are given to the player(s) remove them from the deck and assign to the player(s) - again in the session. Then, when players decide to exchange cards, remove them from the player array and get additional cards from the deck array.

And what section should we be focusing on? Has your own error-checking pointed you to any line numbers?

Help us to help you.

Its not telling the user what hand they got, its like a card game but the deck only has 14 cards, now ou can still get two 8's or two a's but you only have the 14 cards anyway its not calculating what they got in their hand and it keeps taking the money lol

It runs I have attached the link where I have it running, but its not running correctly, It would be easier if an error message would pop up, its not calculating the hand the user has been delt in the end.

hey guys I got it working I will post a link so you can try it out in a little bit, I have to submit an essay….:-9

webdevdea · June 25, 2013

Here is the complete code, I am going to put some instructions on there I think but it works correctly, I renamed the pictures and set up the case for the rest of the deck and it works great now, thanks for the inspiration you are wonderful on here..
