ATTENTION: This is a custom example and WILL NOT work with your installation.
I am sure I can help. I don't have the code for Media Share Suite. The working solution I have is for Clip-Share.
A select query in PHP that would pull the featured videos in the old version would look like this:
$sql = "SELECT v.*, s.username FROM video AS v, signup AS s
WHERE v.type = 'public' AND v.featured = 'yes' AND v.UID = s.UID" .$approv. " ORDER BY v.frank, v.addtime DESC LIMIT " .$limit;
$rs = $conn->execute($sql);
$featuredvideos = $rs->getrows();
frank = This custom mod included adding a new column added to the dbase for featured rank. (Remove v.frank, to remove this extra feature from the above query example.)
With this extra entry in the dbase, Siteadmin can have complete control over video by video over what appears first. Each video has 256 ranking values, so you give the siteadmin custom extra feature to adjust this by custom code modification in siteadmin php and templates.
If you want to hard code alpha or date desc into the query, you could just change it to include ORDER BY adddate DESC, or ORDER BY title ASC.
If you want to give the user the option to reorder the Feature list, then you need to make the area for the ORDER BY text inside the query to be a variable and let the user click sort links that update that variable by changing templates code.
I don't really want to put up too much code, because it's not for the correct version. There is also something to be said about keeping the options simple, so perhaps just making it one way, is best without giving the user more sort options. PM me if you have questions.
