I posted something on this problem a while back but still having problems.
Note that this problem started sometime in June when the viewer for photos changed. Here is what happens:
When I click on "sort photos" in an album the following error messages come up:
Warning: Division by zero in /home/fgmcccom/public_html/photopost/pp-inc.php on line 2140
Warning: Invalid argument supplied for foreach() in /home/fgmcccom/public_html/photopost/templates/forumstyle/orderphotos.tmpl on line 38
If you then select a number other than 0 per page the pics appear but the max available to select is 24 per page. If your album is 24 or less you can sort the photos but if it has more than 24 photos and you try to go to the next page you get the same error messages as above and never make it to the other pages to be able to sort the other photos.
I played with it a little, but you know how users can find things you never thought to check, here is a response from the original poster.
The error messages are gone and if you stick with 12 pics per page you can navigate through the entire album and sort it so it works enough, but there is still something wrong with the drop down menu in that view. Whenever you select another number than 12 from the drop down menu such as 24, it initially shows you 24 pics from the album but every time you try to move to another page, it defaults back to 12 and if you pic 24 again, you will see the same 24 over again and never see the others. Effectively the drop down menu in the sort view does not work beyond one page.
Ultimately it would be better and simpler (if possible) to have a show "entire album" on one page option to select on the drop down. It would make it easier to sort the pics as well.
Ian, are you sure you are in the "sort photos" view of the album vs just viewing the album. If I'm just viewing the album I can select up to 90 pics per page and that works fine, the problem is only in the "sort photos" view, that's the view you can type in the position you want each photo to be in, you can also make any photo your album cover it has a drop down only for 12, 16, 20 or 24 pics per page.
It sounds to me like your user is the one who is looking for an issue where there is none.
The bug with the perpage not being kept when changing pages on sort photos is corrected by the line I posted.
It sounds to me like your user is trying to compare features in other areas of the application with features in totally different areas of the application. Features that might be available when viewing an album or category would not exist in different areas.
The sort photos link for a personal album takes you to a simple page that lists photos in a specific album has pagination and a simple perpage box. You can set a specific order of photos or make an album cover that is it. There are none of the display sorting or advanced features one normally finds when viewing an album or category of photos.
