WordPress MU

HOw do you edit or where in the code of the plugin do you edit it so it will get the custom fields of the posts?

Is there anyone that knows where to or how to edit this code to get custom field keys and values?

The answer was easier than i first thought and Donncha did not help at all even with two emails directly to him.

All you have to do is this
** is a line already in the code
add this after ** line
**158 $permalink = get_permalink( $post_id );
$articlevalue = get_post_meta($post_id, 'articleimg', true);
$thumbvalue = get_post_meta($post_id, 'thumbnailimg', true);
$featuredvalue = get_post_meta($post_id, 'featuredtext', true);

and
**186 add_post_meta( $p, "permalink", $permalink );
add_post_meta( $p, 'articleimg', $articlevalue);
add_post_meta( $p, 'thumbnailimg', $thumbvalue);
add_post_meta( $p, 'featuredtext', $featuredvalue);
this will make it so feature content gallery will work on the main blog

shodezignz, posting what you figured out ... is appropriate.
Adding a "nana nana boo boo" to anyone, but especially Donncha, is terribly NOT appropriate! IMHO.

Thanks for posting the customizations. I also am trying to build a featured content gallery for my WPMU+Buddypress setup front page that can pull posts I want from certain subblogs.

I have a few questions:
- Which is the best (easiest) featured content plugin to use with WPMU?
- Featured content gallery plugins uses mootools I think. Does this conflict with the default jquery library that comes with wordpress?
- I already have sitewide tags plugins aggregating posts in my setup. However, all this time I have had it on a tags blog because I was using the main blog for site news. Is there a way I can use your customized sitewide plugin to look at the tags blog but show the featured section in the main blog frontpage?
- Is there any way I can now transfer the plugin to start using the main blog so that I can use your solution? Would this delete all the posts it has aggregated so far?

Sorry if this is a lot of questions. I have tried to do my research across the forums forums for quite some time but have not been able to find a good solution for what I am trying to do which is to create a featured content slider on the front page which pulls in certain specified posts from specific sub blogs.

Thanks for any help or helpful links you experts can provide!

Kunal

Sorry it took me so long to reply but i have not looked on here since my last post awhile ago.
1. I do not know which is the easiest plugin. I am using the Featured Content Gallery.
2. I am still new to all of this but from what i can tell it does not conflict with anything
3. I think so because even tho you set up a tags blog it should be pulling in the stuff from your main blog too. It is all about categories.
4. I have no idea about that. I think there is a way to transfer posts but i do not know anything about that.

The way i worked everything out was in each sub-blog i made a category Featured and that is what shows up on the main blog page and also in the Featured Content Gallery becasue you can set it to display a certain category. I hope this is helpful and good luck. once again sorry for the late reply Kunal
