I am trying to embed gallery into YaBBSE. I'm starting this by first getting it to use my templates.... a typical page on my site would be like this

<!-- BBCode Start --><TABLE BORDER=0 ALIGN=CENTER WIDTH=85%><TR><TD><font class="pn-sub">Code:</font><HR></TD></TR><TR><TD><FONT class="pn-sub"><PRE>
<?php
$title="A Typical Page";
include ('/home/www/html/template/topnew.php');

<B>Main Content of Page</B>

include ('/home/www/html/template/bottomnew.php');
?>
</TD></TR></TABLE><!-- BBCode End -->

After a bit of reading I tried to add this in init.php (so it doesn't get over written)

$GALLERY_EMBEDDED_INSIDE = "mysite";

and then in wrapper.header I added

<!-- BBCode Start --><TABLE BORDER=0 ALIGN=CENTER WIDTH=85%><TR><TD><font class="pn-sub">Code:</font><HR></TD></TR><TR><TD><FONT class="pn-sub"><PRE>
case "mysite":
$title="gallery page";
include ('/home/www/html/template/topnew.php');
break;
</TD></TR></TABLE><!-- BBCode End -->

This topnew.php file does a bunch of things. It checks if the user is logged into mysite via cookies and outputs top and left nav html. I'm having the problem (I think) that gallery has already sent the headers, and then wrapper.header includes my topnew.php which tries to check cookies etc. and it fails giving me errors...

<!-- BBCode Start --><TABLE BORDER=0 ALIGN=CENTER WIDTH=85%><TR><TD><font class="pn-sub">Code:</font><HR></TD></TR><TR><TD><FONT class="pn-sub"><PRE>

Other errors that are happening....
- its not using mod_rewrite any more - the full path is displayed
- the login does not show up any more....

Am I missing something? Do I need to prevent gallery from creating a session or sending headers?

Ok, I got most of these issues solved through hacking of files rather than using the wrapper (had to put cookie and session info in init.php)

My question now is, is there a good reason that Mod Rewrite gets turned off when you embed?

And second, is it possible to recursivly change ownership of albums? (perl script?)

1)

There's a good reason. Embedded URLs are complicated and inconsistent, and Nuke actually forbids them by default. That said, it can be done (though I don't speak from personal experience). Search the Customization and Nuke forums.

I did a quick search to get you started in the right direction:

http://gallery.sf.net/forums.php?topic=879

2)

Well you *could* write a Perl script. You'd be better off (and have an easier time) writing a PHP script and utilising the Gallery API. If you want to write a mass-permissions editor page for us, we'll gladly put it into Gallery! :smile: Until such a feature gets written though, you'll have to go one at a time.

I haxored the edit_all_props script that I found floating around. I commented out all the changes it was making and added this

$gallery->album->setOwner(3);

I may clean it up so each option has a checkbox and you can select the owner UID from a list if I get a chance. But this worked nicely.

(not cleaned up - but did change all the owners in this case to a user with UID 3

Cool! Right... I'd forgotten about that script.
Maybe getting this working wouldn't be that hard, if you work off of this script.
I'd write it, but it'd be pretty low on my todo list.
Ideally, it would be possible to edit all the permissions, not just the owner. :smile:
