I have a client site where I need to cycle through about 25 different entries on a one per day basis.  In other words, I need to load one entry per day until I have exhausted the 25 entries, and then continue to repeat or cycle through that procedure.

The client wants one free song to be featured each day.

Any ideas?

Probably requires a bit of PHP. I’d take the current date, divide by 25 (or how many songs there are), take the remainder, and volia: The magic number. The rest is custom fields and a custom weblog.

Alright - I will look into it!

I’d take the current date, divide by 25 (or how many songs there are), take the remainder, and volia: The magic number.

Maybe its cos its late, but how would that loop through one a day?

We don’t want to loop through one day, but get a new entry every day, then restart after 25 days. At least that’s what I understood. So, if we take, I dunno, the number of the day of the year, we’d get:

... effecitvely looping through 1 ... 25.

hey thats cool :D i still cant get my head around exactly whats going on there, but cool all the same…

so that is taking the day of the year, adding one, dividing by 25 and adding one to the remainder will always be one of the id’s?

Well, yes. Do you want me to break it down for you? The day of the year ranges between 0 and 365, so we add 1 (0 dividing by anything is not much fun). Today is the 148th day, so that’d be 149. Divide by 25 and keep only the remainder (“modulo operation”):

Add 1, and we get 25. Tomorrow will be the 149th day, so 150/25 = 6, remainder 0, +1 = 1, we’ll start over again. Lather, rinse, repeat.

ahh wow! hey thats cool :D i should have paid more attention in maths… it would make my job so much easier :D thanks for explaining that.

Very nice!
