On my site, I am having a sort of slideshow in which people can purchase the ability to put a picture on. It's sort of a one shot deal thing, in which someone can go on and navigate to a page that allows them to pick a picture, give a description, and then choose a payment option. This payment option is something like if they want their picture to be shown for 10 seconds, it will cost $1, 20 seconds would be $2, and maybe a minute for $5 or some sort of deal. On top of that, I also would like to have a part in which they can choose the number of times they want it shown for that time, such as two 10 second deals, although it'll still be the same picture, and that will then double the cost. However, my question is how to do this. I need to be able to remove their picture from a database after it's been viewed, unless they've purchased a quantity of two or more, in which case I need the fact that it's been viewed once already reflected in the database. I have no idea how to count how many times it's been used in the slideshow, nor how to set a time limit in the slideshow. Any help would be appreciated and if you have questions don't be afraid to ask. -- Posted via http://www.ruby-forum.com/.
