Hi guys, I'm working on a complete revamp of Effervescence and having a lot of fun with the new features.

The way I've got image descriptions and tags implemented is to check via getImageDesc()!="" and getTags()!="" that these fields are not empty, so as to make the styling cleaner if they are absent.

I would like to do the same with EXIF data. How can I check that the EXIF indeed contains information and not a blank array?

You can check the EXIF fields directly (please see the documentation) or you could probably try some PHP array functions like count, in_array or sizeof for example (see http://www.php.net/)

BTW, nice effervescent mod, but horizontal scrolling is really a little inconvenient...

Thanks, I'll try and figure it out with PHP. It's not exactly my strong suit.

Regarding Effervescence, the horizontal scrolling is just a fun little thing I added for my own gallery. I'm actually starting off from scratch for v2. I might even have to give it a new name, because I have a feeling it will be quite different from my original Effervescence theme.

I'm also realizing that getTags()!="" is not a good way to check whether the list of tags is empty or not. Do you have tips on how I could do this with PHP?

Alright, I somehow actually didn't realize that you are the original author, sorry...:-) Needless to say that any new theme is welcome.

Since these are all arrays, I would think that the php array functions count might be suited for that:

Got it to work with both tags and EXIF, cheers!

Just for reference I'm using count(getTags())!=0 and count(getImageEXIFData())!=0 to check whether the tags or EXIF contain any data.

This is what i'm looking for i believe. Where did you implemented the count in the image.php or somewhere else and how?
