subalbums next/prev album

amyg

Has anyone worked out a way to make the 'next and previous album' work with subalbums?
Right now, the links send me back to the main gallery page.
thanks in advance

Not sure exactly what you are saying, but you might want to check out the effervescence+simpleviewer theme. It has full paging of subalbums.

Maybe I just needed sleep - I'll try it again - I'm pretty sure I tried with the E.S theme

I want to use this function:
http://www.zenphoto.org/trac/wiki/DeveloperReference#getNextAlbumURLandgetPrevAlbumURL

But what happens is that instead of going to the next album - i end up back at the gallery index - or the next gallery.

I just want users to be able to go album to album, with out having to go back to the index.

OK. That function does not yet support subalbums. So it is defaulting to the gallery. I took a quick look. The hack to provide subalbums is not hard, but also not trivial. You would have to make subalbum versions of `getNextAlbumURL`, `getPrevAlbumURL`, and the supporting routines: `getNextAlbum`, `getPrevAlbum`, `getAlbums` (you probably can use `getSubAlbums` for this), and `getAlbum`.

OK - I'll try to get my head around that and give it a go
thanks for getting back.

sbillard, I tried to use your code for ticket #2 here: http://www.zenphoto.org/trac/ticket/2 but I see now place to import
subalbumfunctions.php

I replaced my other 2 templates with yours and it doesnt break anything but I dont get to page either. Could you let me know what I am going wrong?!

sbillard

Here is the code you need:
`<?php<br />
/** Next and Prev SubAlbum URLs */

function getAlbumsCount() {

global $_zp_current_album;

$parentalbum = $_zp_current_album->getParent();

$id = $parentalbum->getAlbumID();

$sql = "SELECT COUNT(*) FROM ". prefix("albums") ." WHERE parentid = $id";

$result = query($sql);

$count = mysql_result($result, 0);

return $count;

}

function getNextSubalbum() {

global $_zp_current_album;

$parent = $_zp_current_album->getParent();

if (is_null($parent)) {

$result = $_zp_current_album->getNextAlbum();

if (!$result) {return null;} else {return $result;}

}

$subalbums = $parent->getSubAlbums(0);

if (($inx = $_zp_current_album->index) == null)

$inx = array_search($_zp_current_album->name, $subalbums);

$inx = $inx+1;

if ($inx >= 0 && $inx < getAlbumsCount()) {

return new Album($parent, $subalbums[$inx]);

} else {

return null;

}

}

function getPrevSubalbum() {

global $_zp_current_album;

$parent = $_zp_current_album->getParent();

if (is_null($parent)) {

$result = $_zp_current_album->getPrevAlbum();

if (!$result) {return null;} else {return $result;}

}

$subalbums = $parent->getSubAlbums(0);

if (($inx = $_zp_current_album->index) == null)

$inx = array_search($_zp_current_album->name, $subalbums);

$inx = $inx-1;

if ($inx >= 0 && $inx < getAlbumsCount()) {

return new Album($paraent, $subalbums[$inx]);

} else {

return null;

}

}

function hasPrevSubalbum() {

if (is_null(getPrevSubalbum())) {return false;}

return true;

}

function hasNextSubalbum() {

if (is_null(getNextSubalbum())) {return false;}

return true;

}

function getNextSubAlbumURL() {

if(!in_context(ZP_ALBUM)) return false;

$nextalbum = getNextSubalbum();

return rewrite_path("/" . pathurlencode($nextalbum->name),

"/index.php?album=" . urlencode($nextalbum->name));

}

function getPrevSubAlbumURL() {

if(!in_context(ZP_ALBUM)) return false;

$prevalbum = getPrevSubalbum();

return rewrite_path("/" . pathurlencode($prevalbum->name),

"/index.php?album=" . urlencode($prevalbum->name));

}

?>`

put this into your custom-functions.php

lovely!
Thanks again sbillard
