Automatically select "next" image every 24 hours?
« on: May 07, 2008, 08:10:58 PM »
Hi everyone,
 
 I'm fairly new to PHP and MySQL, and there's something I'm trying to do that I can't quite figure out. If anyone can provide some insight I'd appreciate it.
 
 What I want to do is store an image file name in a MySQL database, linked to a sequentially-assigned number (1, 2, 3, etc.) that would be the primary key. Then, in the PHP code that displays the image, I want to retrieve and display the data associated with primary key #1. The next day (at midnight?) I want to display the next image, associated with primary key #2. Then after that, the image associated with #3, etc.
 
 It sounds like this is what I need to have happen:
 
 PHP code, when the page is called, displays image associated with primary key #1.
 Server date/time advances to the next day.
 PHP code, sensing the server date/time, increments the primary key up by one. When the page is called, it displays the image associated with primary key #2.
 
 So, first, does this logic sound right?
 Second, any direction I should follow when writing this?
 
 I'm just now learning PHP and MySQL, so any assistance would be wonderful. Thanks!
