New From WPMU DEV: Cloner, the Site Cloning Plugin for WordPress Multisite

Sometimes you just need to make an exact copy of a site in your WordPress multisite network and you want to do it as quickly and as painlessly as possible. Other times you just want to copy all the users or posts.

Cloner, the latest WordPress multisite plugin from WPMU DEV allows you to effortlessly clone all or part of a site in your network. No fuss, no bother just a couple of clicks and it’s done.

Perfect for worry-free troubleshooting, staging, adding users to a new or existing site and distributing content across multiple sites, Cloner is destined to quickly become an essential tool for every WordPress multisite network owner.

Cloner is the latest addition to the WPMU DEV suite of site copying tools that includes Snapshot, New Blog Templates and Multisite Content Copier.

Each has its own particular focus and Cloner is the result of requests from users of CampusPress, WPMU DEV’s WordPress-powered education blogging tool.

It allows a network’s Super Admin to clone components (there are 9 to choose from) from one site to either an existing site or to a new site simply by entering the site’s slug and clicking on Clone Site.

Why Is That Useful?

There are a number of scenarios why being able to clone a component of, or an entire, site would be hugely beneficial to a WordPress multisite network owner:

Troubleshooting – we’ve all had the experience of an issue being reported on a site that requires the kind of debugging that just isn’t possible on a live site. Cloner allows the Super Admin to quickly and easily replicate the site to a private area for some in-depth prodding and poking out-of-sight from the site’s owners.

Creating new sites just like that one – another common request is to have a new site that looks and works just like an existing site. Cloner allows the Super Admin to do this in a couple of clicks. Of course, if the request is common enough then a “model” site can be created that can be copied as required.

Cloning a site’s users – there are often times when you might want to provide the users of one site with access to another. Using Cloner, the Super Admin can specify that only users are to be cloned meaning that everything else on the destination site remains in tact.

Staging – related to troubleshooting, Cloner is perfect for cloning an a test site to a public location (and leaving the test site fully operational) or for creating a test version of a live site to be worked on before cloning back to the live site.

No doubt that has piqued your interest, so let’s look at how the Cloner plugin does its job.

How Does It Work?

Let’s walk through a simple example to show you how it works.

You need to start with a multisite network, of course. I’ve set one up using sub-directories and I’ve installed and network activated the Cloner plugin.

Step 1 : Configure The Plugin’s Settings

The first thing to do, is configure the plugin’s settings which are under Settings > Cloner in the Network Admin interface:

As you can see, there are 9 possible components that can be selected including custom tables which you’ll definitely welcome if you have any plugins installed that create their own data store. Posts will include everything in the Post table that has a status of publish, including custom post types.

I’m going to leave all the options checked as I want to clone an entire site.

Next step is to select the site to clone.

Step 2 : Select Site To Clone

Selecting the source site couldn’t be easier. Go to Sites in the Network Admin interface and when you hover over a site, you’ll see Clone in the list of actions.

Click on Clone and now we’re ready to specify the destination site.

Step 3 : Specifying the Destination

Cloner can either create a brand new site, or overwrite an existing site. In the case of an overwrite, only those components you specified in the plugin’s settings will be overwritten, allowing you to clone a list of users, for example.

Let’s create a new site by ensuring that the Create New Site radio button is selected and that a new site name is entered in the textbox.

If you select Replace Existing Site then you will be asked to confirm that you really want to do this.

Click on Clone Site and the plugin will start copying your site to a new or existing site. How long it takes will depend on how much content the original site contains, particularly the number of attachments.

When the process is complete you are automatically redirected to the Admin interface of the new site.

If the operation was a full clone then it’s probably a good idea to jump into Settings > General and change at least the site title so that you can more easily identify your clone.

As you can see, with Cloner, making replicas of your network sites is incredibly easy and you are probably already thinking about uses for this tool that I haven’t even mentioned.

If you are a WPMU DEV member then you can download and try Cloner now.
