Turn off Sitewide Tags on special blogs

Ron — Sun, 05 Sep 2010 00:30:04 +0000

If you want to turn off the post copy in the Sitewide tags plugin on a special site/blog, you can do it with a one line plugin as follows:

remove_action('save_post', 'sitewide_tags_post', 10, 2);

Install the plugin in the plugins folder and activate the blogs/sites you don’t want the SWT plugin to copy posts to the tags blog.

Using the sitewide tags plugin

andrea — Fri, 03 Sep 2010 15:56:31 +0000

I often recommend the use of the Sitewide tags plugin as a means to pull in all the posts from all the sites across the network to the front page, or a secondary blog.

Even though the plugin is pretty straightforward, a lot of people get tripped up on the little details.

Installation: Install the plugin file in the mu-plugins folder please. This way it works across the entire network and is immediately working. If not, you can run it from the plugins folder but it *must* be network activated. Read more about the mu-plugins folder here.

Setup: after install, visit the Super Admin -> Options menu page.

Scroll down and tick the checkbox to tell the plugin to start gathering new posts.

Now we have a couple options to set here. In the screenshot below, I’ve set it to send posts to the main blog in the network.

(click for bigger)

New posts will be added as they are published to the public sites. If the privacy setting is set to anything else, these posts will not pull through to the tags (or main) blog. You can find the privacy setting under each site’s Settings -> Privacy menu.

For a working example, visit the home page of HomeschoolJournal.net.

Mark your calendars

andrea — Tue, 10 Aug 2010 19:34:16 +0000

Late August is going to be a busy time, I’m going to be doing 3 appearances this month, two virtual and one in person.

August 19th I will be giving a webinar on multisite for the guys at webdesign.com. Curious? Then this one is for you. (You need a webdesign.com membership.)

August 21st I will be Skyping in to WordCamp Savannah to talk about some of the best plugins for network installs. This is also awesome, because it opens up HUGE possibilities for other WordCamps that may want a speaker who is unable to be there in person.

August 28th both Ron and I will be speaking at WordCamp Montreal. I’ll be talking about enabling the network and domain mapping, while Ron will be digging deep into code and go over how you can write plugins with the network / multisite in mind. We’ll be driving up, as it’s the closest WordCamp to where we live and a “short” 7 or 8 hour drive. Added bonus is we’ll be bringing our daughter Sarah who is studying to be a graphic designer at the New Brunswick College of Craft & Design. So if you see us there, be sure to say hi and give her plenty of advice.

SharDB 3.0.1 Update

Ron — Tue, 03 Aug 2010 22:14:05 +0000

Over the weekend I updated SharDB to allow installs to upgrade from WordPress MU 2.9.2 to WordPress 3.0.1.

I also did an initial pass at support for new WordPress 3.0 -> WP network in SharDB. In this implementation the main site’s tables will be in the global database. You can easily set up a test install (to test your plugins, etc. with SharDB). Set up a fresh install that has the network enabled, create your database shards, then configure & install SharDB.

Return a list of sites on the network

andrea — Thu, 22 Jul 2010 12:38:22 +0000

Here’s a simple internal function that will return a list of all sites in the network. The code below just shows them all and unlinked.

$blog_list = get_blog_list( 0, 'all' ); foreach ($blog_list AS $blog) { echo 'Blog '.$blog['blog_id'].': '.$blog['domain'].$blog['path'].' '; }

Paste that somewhere in a theme file or page template and there you go. Hope someone finds it handy and gets inspired to write a snazzy plugin, possibly a shortcode.

Theme Stats Updated

Ron — Thu, 22 Jul 2010 02:46:35 +0000

I updated the theme stats plugin to work with new WordPress 3.0 networks as well as with MU installs upgraded to WordPress 3.0. You can download it here: WordPress Network Theme Stats.

Get some simple Network stats

andrea — Tue, 20 Jul 2010 12:33:43 +0000

I remembered this really neat internal function that is handy to display anywhere you want to show how many sites and users you have in your network.
$stats = get_sitestats(); echo 'There are currently '.$stats[ 'blogs' ].' sites running on this network and '.$stats[ 'users' ].' users.';

Surround that in php tags.

For added snazziness and extra bonus points on your homework, go grab a copy of the blank widget Blank Build-A-Widget (994) paste this code in there, and you’ve just made a network stats widget. Awesome, you rock

WordCamp Montreal

Ron — Mon, 19 Jul 2010 23:17:14 +0000

Both Andrea & I will be speaking at WordCamp Montreal.

Andrea & I have had a fantastic time at every WordCamp we have attended and we enjoy meeting other people who use WordPress. If you have never been to one, this will be a great one for you to attend. Whatever you are doing with WordPress, you can be sure that you’ll have a chance to talk to others who have been or are interested in doing the same

Change the default theme for sites without a plugin

andrea — Sun, 18 Jul 2010 16:28:06 +0000

There’s a new and very little documented feature in 3.0 for changing the default theme. And? This will work on single WordPress installs as well as being handy for a network of sites.

The magic line is this in your config file:

define('WP_DEFAULT_THEME', 'classic');

In this example, the classic theme is used as the default when a site is created, or when a theme in use is removed. If you are starting fresh with 3.0, the default is the new TwentyTen, so this override is handy.

Added tip: if you have a lot of blogs using the Kubrick theme and wanted to remove it and set the other blogs, do this define first with your new default theme, then remove or rename the Kubrick theme folder (in my it was simply “default”). On a refresh, all blogs using the Kubrick theme will be switched to your new default.

If you just wanted the Kubrick theme to go away and have twentyten show up, you won’t need to do the define above. Just rename the /default/ theme folder. It’ll kick in.

(thanks to Ron for reminding me & MichaelH for the codex note I missed)

Last updated sites widget

andrea — Thu, 15 Jul 2010 13:42:51 +0000

This is a handy little widget that will pull a list of all the sites in your network and order them by last updated. The code for this was originally in the home theme of the WPMU download, so thanks to Donncha for that bit.

Last Updated Sites widget (113)

I tested it in the mu-plugins folder, but you should also be able to use it as a regular plugin as it only needs to run on one blog. It’s also the older widget code, so you can only use it once, not multiple times, and it has no options. Short, sweet & simple.
