I have a few questions about sorting options. I'm trying to create a gallery where you can view pics according to a category: event, player, etc. For example, could plogger display photos from a football game, but also allow the user to view just the pictures of one player (maybe even from multiple games).
Is there a way to dynamically change the galleries displayed? Like this?
Or would I have to create a collection for 2009 Game Galleries, and then another semi-redundant collection for 2009 Individual Players?
Your options really include the above work around you mentioned or tagging the player photos with a specific tag so that a search feature could pull them all up. To hide to the user that they were in fact using a search, you could us a button and some PHP to pass a search result called say player to the url so that on that button click they will get a "gallery" (in fact it is a search result return of the players) of just the players. If you wanted to further make it look nicer you could also you a mod rewrite to make the search url say something fancy like /photos/playergallery when in fact they are on /photos/seach=players for example.
I do it with my galleries to rewrite the urls to the full size images so that someone does not see the true location of the pictures.
So I went home and thought more about this and realized that this is something very useful. I hope when the plogger dev's get back they see this, because I think this is something very good to have in a photo album. Having "smart albums" which are based of tags and not always albums for example.
