Hi. I'd like to find a way to add a css class (or id) to the body element, depending on the main parent album that I'm in. So that I can create special styles only for certain albums. For example: <body class="parent-album-id-7">. Does anyone know how to do this ?

This function gets the top level parent of an album:

So how exactly should I use it ? I have tried these:
<body class="top_album_<?php getUrAlbum() ?>">
<body class="top_album_<?php getUrAlbum("mariages") ?>">
<body class="top_album_<?php getUrAlbum(mariages) ?>">
<body class="top_album_<?php getUrAlbum($album) ?>">
none of them work - I get top_album_(empty) . What should I replace "$album" with ?

If you want it to be printed you need use `<?php echo getUrAlbum($album) ?>`.

I've tried `<?php echo getUrAlbum($album) ?>`, but I still get no result - it's just empty. You can see a gallery page here.

The image is the album "mariages", which is in the album "laeticia". I need to get that top album printed. Any ideas ?

You need to pass the album object of the current album to that function (sorry forgot to say but it's actually documentated):
`getUrAlbum($_zp_current_album);`

still no success - worse, it actually makes everthing coming after `<body id="page_album" class="top_album_` totally disappear from the html source code (so page content is gone)... What am I doing wrong ?

the zenphoto files (index.php, zp-core folder etc) are in the root folder - could this be the problem ? (or the fact that php safe mode is still on ?)

You should review the function definition/documentation for that function. It returns an album object, not a string. Try `$album = getUrAlbum($_zp_current_album); echo $album->name;`

Generally, it is a good idea to read the documentation on functions you intend to use. Don't expect the developers to remember details while reading posts.

Thank you sbillard and acrylian. My body element now looks like this: `<body id="album_<?php $album = getUrAlbum($_zp_current_album); echo $album->name; ?>">` - it works.

Sorry for my ignorance. Thanks again.
