Clones an existing site into a new one in a multisite installation : copies all posts, settings and files

Description

MultiSite Clone Duplicator adds a "Duplicate Site" functionality to your network installation.

It allows you to clone any site of your network into a new one : all data, files, users and roles can be copied.

It is useful when you want to create multiple sites from the same template : Don't waste your time copying the same configuration again and again !

Simple and user-friendly, this plugin extends WordPress core network's functionalities without polluting the dashboard.

WARNING : If you clone the primary site, you must use mucd_default_primary_tables_to_copy filter to declare plugins and custom database tables, or your cloned site won't be complete

Features:

Clones any site of your wordpress multisite installation
Copies all posts and settings
Generates log files (if option is checked)
Copy all files from duplicated site (if option is checked)
Keep users and roles from duplicated site (if option is checked)
Configure which site is clonable (so you can define an unique "pattern" site)
Fully hookable
Command line ready (provides a WP-CLI subcommand)

Installation

You can install MultiSite Clone Duplicator using the built in WordPress plugin installer. It’s easy, 2 seconds.

If you prefer download MultiSite Clone Duplicator manually :

Upload multisite-clone-duplicator/ to the /wp-content/plugins/ directory
Activate the plugin through the 'Plugins' menu in WordPress
(Optional) Chmod 777 the logs/ directory of the plugin, if you want to activate logs
Go to My Sites > Network Admin > Duplication and enjoy !
(Optional) Change default options into Network dashboard > Network settings > Duplication

In the future, you'll probably want to create a dedicated "template" blog to clone from.

Frequently Asked Questions

How does it work ?

It creates a new user if the email was not an existing email
It creates a new blog with appropriate title and admin user
It copies all tables from cloned site, but keep some options (like title, domain, etc) of the new blog
It searches and replaces old site's URL and DOMAINS with the new ones
It copies upload directory from the old site to the upload directory of the new one (if option is checked)
It imports users and roles from the old site to the new one (if option is checked)

Does it support subdirectory AND subdomain installations ?

Yes, it supports both !

Can I clone the primary site ?

Yes you can, but you want to be careful : WordPress saves network tables and primary blog tables with the same prefix, and some of their data are mixed. It forces us to restrict primary blog cloning to copy only the default wp tables. If you want to change this (for example, include your plugin tables in the cloning), use mucd_default_primary_tables_to_copy filter. In the future, you want probably not to copy again and again the primary blog : use a "template" blog dedicated to clonage instead.

Does it clone plugins settings ?

Yes it does !

But some data are serialized ?

It's not a problem ! Serialized data are understood by the plugin, recursively unserialized, replaced with appropriate values, and serialized again.

After cloning, new site was created, but it goes on 404 page, why ?

Check your host / server configuration : you probably cloned your site into a domain that is not available !

How to duplicate with command line commands ?

Install WP-CLI, go to your wordpress multisite directory, and type

wp-cli site duplicate --source=<id_of_the_site_to_clone> --slug="<slug_of_the_new_site>"

Arguments are :

wp site duplicate --slug=<slug> --source=<site_id> [--title=<title>]
  [--email=<email>] [--network_id=<network-id>] [--private] [--porcelain] [--v]
  [--do_not_copy_files] [--keep_users] [--log=<dir_path>]

Which languages are currently supported?

As of now, following languages are supported : English (en_US), French (fr_FR), Spanish (es_ES), Lithuanian (lt_LT) and Greek (el). If you wish to, you can translate the interface in your own language in the standard WordPress way or with Transifex

multisite-clone-duplicator's Issues

Unused variables

You can use PHP Mess dector (https://phpmd.org/) to detects when a variable is not used.

Add select2 support

See https://github.com/pierre-dargham/multisite-clone-duplicator/tree/feature_select2

Does not work with visual composer

I suppose it's because this plugin uses no-wordpress tables like 'prefix_revslider_sliders'.

But I get this error (data aren't copy to that tables)

No longer works

I use to rely on this plugin for my localhost workflow when testing out my design ideas.
Your plugin last worked in April 2020 on vanilla WordPress Multisite, the most up to date version at that time, but no longer works with the current WordPress.

Flush cache when catching error

function duplicate_site,

if ( is_wp_error( $to_site_id ) ) {
wp_cache_flush();
$form_message['error'] = $to_site_id->get_error_message();
return $form_message;
}

Usermeta table data exponential duplication

The problem is like as described in issue #62 but I do duplicate not from the main site. A lot of meta keys like 'wp_34_15_14_2_user-settings' are created.

Thank you!
Alexey

Set default log directory into uploads folder

Log directory should never be into the plugin folder

https://github.com/pierre-dargham/multisite-clone-duplicator/blob/release/1.3.3/include/option.php#L62

Remove the log directory from the plugin
Set default log directory into something like <uploads_directory>/multisite-clone-duplicator-logs/

Does not change url in table prefix_posts

Considering I have the following url in the main site
'myurl/mysite/apage.html'
I create the following subsite:
'myurl/mysite/newsubsite/'

The url is not changed and is still 'myurl/mysite/apage.html' instead of 'myurl/mysite/newsubsite/apage.html'

Broken images in medialibrary showing if not checked "duplicate files..."

If I do not check "Duplicate files from duplicated site upload directory" the media files show up anyway in the cloned installations media library, but as broken images ( non existant ).

WooCommerce support - Foreign key ?

An error occurs during a duplication with WooCommerce.

MUCD_Data::copy_data() doesn't correctly replace all strings

A very simple way to replicate the problem is:

create a sub-directory multisite (e.g., with main site URL https://example.test)
add a post to the main site that contains a gallery block (with "Link To: Attachment page")
add an image to the gallery
save the post
duplicate the main site (e.g., with new site URL https://example.test/new-site)
examine the post_content in the new site and you'll see that while the img/@src has been correctly replaced, the a/@href (and @img/@data-link) has not!

Note: this problem is not a result of plugin/theme custom tables in the main site not being duplicated.

For example, given post_content in the main site such as:

<!-- wp:gallery {"ids":[1592],"imageCrop":false,"linkTo":"attachment"} -->
<figure class="wp-block-gallery columns-1">
  <ul class="blocks-gallery-grid">
    <li class="blocks-gallery-item">
      <figure>
        <a href="https://example.test/my-post/my-image">
          <img src="https://example.test/wp-content/uploads/2019/10/my-image.jpg" alt="" data-id="1592" data-link="https://example.test/my-post/my-image/" class="wp-image-1592"/>
        </a>
        <figcaption class="blocks-gallery-item__caption">My cption</figcaption>
      </figure>
    </li>
  </ul>
</figure>
<!-- /wp:gallery -->

it should result in post_content in the new site such as:

<!-- wp:gallery {"ids":[1592],"imageCrop":false,"linkTo":"attachment"} -->
<figure class="wp-block-gallery columns-1">
  <ul class="blocks-gallery-grid">
    <li class="blocks-gallery-item">
      <figure>
        <a href="https://example.test/new-site/my-post/my-image">
          <img src="https://example.test/new-site/wp-content/uploads/sites/2/2019/10/my-image.jpg" alt="" data-id="1592" data-link="https://example.test/new-site/my-post/my-image/" class="wp-image-1592"/>
        </a>
        <figcaption class="blocks-gallery-item__caption">My cption</figcaption>
      </figure>
    </li>
  </ul>
</figure>
<!-- /wp:gallery -->

However, the actual post_content in the new site is:

<!-- wp:gallery {"ids":[1592],"imageCrop":false,"linkTo":"attachment"} -->
<figure class="wp-block-gallery columns-1">
  <ul class="blocks-gallery-grid">
    <li class="blocks-gallery-item">
      <figure>
        <a href="https://example.test/my-post/my-image">
          <img src="https://example.test/new-site/wp-content/uploads/sites/2/2019/10/my-image.jpg" alt="" data-id="1592" data-link="https://example.test/my-post/my-image/" class="wp-image-1592"/>
        </a>
        <figcaption class="blocks-gallery-item__caption">My cption</figcaption>
      </figure>
    </li>
  </ul>
</figure>
<!-- /wp:gallery -->

As mentioned, this has to do with the way MUCD::replace() is written. What happens is the following:

MUCD_Data::db_update_data() calls MUCD_Data::update() which eventually calls MUCD_Data::replace( 'the post content', 'https://example.test/wp-content/uploads', 'https://example.test/new-site/wp-content/uploads/sites/2 )
- That replacement happens correctly
MUCD_Data::db_update_data() calls MUCD_Data::update() which eventually calls MUCD_Data::replace( 'the post content', 'https://example.test', 'https://example.test/new-site' )
- That replacement does not happen correctly
- the reason is that MUCD::replace() notices that the $val already contains 'https://example.test/new-site' (because of the previous replacement) and so does not do the replacement
- this particular problem can be fixed in MUCD::db_update_data() by changing the order of the strings in $string_to_replace, putting $from_blog_url => $to_blog_url first
- that works since $to_blog_url will be shorter than $to_upload_url (unless a site has done something really weird with changing the location of their uploads folder), and therefore, it is much more likely that $to_upload_url will not already exist in the post_content
- however, I haven't tested enough to know whether changing the order of the replacements causes other problems

WordPress 4.7.2

Minor: Doesn't work on WP 3.5 and 3.6

I'm forced to use a very old version of WordPress at one of my clients, and I noticed that the Clone Duplicator does not work on 3.6 because it uses wp_get_sites (introduced in 3.7).

Personally, I'd probably fix this by updating the wp.org "requires" tag to 3.7 :).

The plug-in stopped to clone and provides a new fresh installation instead

Hello,
Hope you're doing well :)

I'm using MultiSite Clone Duplicator for several months and it always worked perfectly. Next week (before the last update of the plug-in 2 days ago), I used, as usual, my dedicated "template"/sub-site to clone from to create a new sub-site on my network for one of my new pupil.
Instead of cloning the dedicated sub-site, the plug-in install now a new fresh Wordpress, like when you install WP for the first time.
Since the last cloning success, I just added a new plug-in "Corner Ad", not activated on the network, and nothing else...
Then, when I saw that there was a new update 2 days ago, I thought that it would fix this issue but no, the problem is still the same...

Thanks a lot for your help.

Best Regards,
Laurent O.
PS: Sorry for my english :)

Error while cloning site in wordpress multisite

Duplication failed :

Unable to Duplicate in Multi-Site

Whether duplicating an existing site or creating a "new" site, I get the following error:

Never had this problem before, now this is CONSTANT. Please help.

SSL Issue

Whenever I clone a site, it strips out the https for the Media uploads and causes a mixed content issue, thus showing these sites as not secure. Using Divi and the theme builder for these sites as well.

duplicating a site with WPML Language Plugin Not work

WPML multi language site duplication site is not showing pages.

Allow target site to use a domain name independent of subdomain

Currently:

Primary site: domain.com
Child site: foo.domain.com
Duplicated site with slug bar: bar.domain.com

Using domain mapping, it is possible to reconfigure a child site into something like foo.com.

It would be useful to duplicate directly from foo.com into bar.com, and expect all the urls to come out correctly.

The filter mucd_string_to_replace allows overriding this effectively on a case by case basis, but it would be nice to include in the plugin UI as via a wp-cli option.

Additionaly, there are rumors that domain mapping will be a core feature in 4.4, mentioned in this support thread. In that case, this would be a natural addition to this plugin.

Thanks for the plugin and wp cli attention, much appreciated!

shortcode erroneously gets altered

After cloning a site using the Jupiter theme, a shortcode was altered (breaking it) from vc_wp_custommenu to vc_wp_3_custommenu, presumably because the database prefix was matched.

This is with the current latest version; 1.4.1

Any chance this can be fixed?

Incompatibility with intuitive-custom-post-order

Several users reported incompatibility with https://fr.wordpress.org/plugins/intuitive-custom-post-order/ (when activated, duplication ends up in some fatal error)

MSCD breaks core functionalities

MSCD forces check on admin referer, but doesn't check if $_POST is delegated for it. In this case i. e. delete blog functionality fails (check_admin_referer throws 403).

Delete blog has referer named 'confirm', but plugin checks for siteoptions (even though form is not for it). Forms should have hidden value which would allow to check if $_POST request is for plugin or not.

if ( ! empty( $_POST ) && check_admin_referer( 'siteoptions' ) )

Plugin can't be uninstall from the back-office

upgrade to wordpress 4.9.4 support

Hello @pierre-dargham

I test it in wordpress 4.9.1, and it works well, but I found it does not support wordpress 4.9.4.

It will show a white page and no roles and user would be duplicated.

Would you please upgrade it?

Thanks

How to use mucd_default_primary_tables_to_copy ?

You must use mucd_default_primary_tables_to_copy filter to declare plugins and custom database tables, or your cloned site won't be complete.

Problem with subsite clone

Hi team,

Recently, I duplicate a subsite in my multisite and have some troubles:

After running duplicate button, it loads a couple of seconds and show up a blank page with nothing. I have to access All site to see the new site.
I already tick "Keep users and roles from duplicated site" but it doesn't copy from the old site to new site.

Could you check this issue, please?

IDs of cloned tables

this is as much to confirm my theory as anything else, but when a site is cloned, the post IDs (and related meta IDs, etc) will be identical to the source site, correct? (I'm looking to run a function after the site was cloned to map some post meta)

related: I don't see any actions that run after the cloning is complete. Is there something I don't see?

No option mucd_default_primary_tables_to_copy

Cloning a primary site works 'out of the box', there is no option to enter 'mucd_default_primary_tables_to_copy' as depicted in the documentation. If I check in the database there are 10 additional tables for the cloned site just like the other subsites.

Compatibilty with MultilingualPress ?

Using MultiSite Clone Duplicator 1.4.1 (Last Updated 1 year ago) I got problems with my WordPress 4.9.5 Multisite Installation and MultilingualPress 2.11.0 (Last Updated 4 months ago) Enable automatic redirection function (by browser language). A collegue found out that by the duplication the Front Pages of two multisite instances had the same ID what caused the problem in the MultilingualPress not redirecting as expected on the duplicated site. Manually creating a new Front Page (with new ID) solved the problem.
Not sure if this is caused by MultiSite Clone Duplicator or should be solved in MultilingualPress. As I see MultiSite Clone Duplicator was not updated since a year and other database/core/MS issues are reported I can not anymore trust this plugin and will deactivate it until this and other issues get solved.

Documentation mistake

Greetings,
The hooks listed in your readme/description are incorrect. The are in all caps, and the hooks actually used are all lowercase. Hooks are case sensitive, causing your documentation to be very misleading. Otherwise, great plugin so far.

get_sites max returns 100 sites

We need to replace the old limit arg of deprecated function wp_get_sites with the new number arg of get_sites

See https://wordpress.org/support/topic/original-site-to-copy-only-showing-first-100-sites/

wp_user_roles

I've encountered a bug while using your plugin. It's the same as this one: http://wordpress.stackexchange.com/questions/11725/why-are-my-roles-not-visible-in-a-multi-site-network

Could you make sure the wp_user_roles is renamed to wp_<site_id>_user_roles so the problem is solved?
Thanks!

Problem wi

Hello
i am using the iOS app with some multisites. one of the site is duplicated of an existing multisite with the wordpress-plugin multisite clone duplicator.

after adding the clone-site to the app, the app shows as blogname the original-site name in the list of websites. but the name of the clone-site is already changed to "clone".

after adding the original-site to the app, with the url of the original site, the app adds the clone-site as a second instance.

now one of the clone-sites in the website-list is shown as "original" and one as "clone". But the url of both is to "clone"

after tapping the clone site with the name "original" to edit some stuff, i see as blog name "original". after going back to switch another site the names in the list switches in a random way from "original" to "clone" or backward.

maybe its a problem of the app, i asked already in the iPhone forum of wordpress:
https://ios.forums.wordpress.org/topic/app-shows-the-wrong-multisite?replies=1

thank you

[Fri Sep 15 12:14:47.592317 2017] [fcgid:warn] [pid 27144] (32)Broken pipe: [client 172.31.1.119:53682] mod_fcgid: ap_pass_brigade failed in handle_request_ipc function...

even after changing nginx proxy configs to:

send_timeout 3000;
proxy_connect_timeout 9000;
proxy_send_timeout 9000;
proxy_read_timeout 9000;

Something is really messed up.

Check plugin url / dir consts

See cb11a44

See #9

Add language : zh_CN

See #14

If the language file works for the 1.x versions, add it (check it wasn't made for the 2.x version)

HOW IS THIS DONE?WARNING : "use mucd_default_primary_tables_to_copy filter to declare plugins and custom database tables, or your cloned site won't be complete."

After duplication screen is empty

Not sure if this is a bug or not but after duplicating a site the content area is blank. There's no success message or redirect to back to /network/sites.php.

I've posted a screenshot of what I mean. I'm using version Version 1.4.1.

Thanks
Eric

error 502 or new cloned site or existing sites

I've installed the plugin and duplicate a 'simple site' and it seems to works.
But when I try to login in admin on the new site (or existing sites, no on network admin) I've 502 error!
I've deactiveted all plugins, but it's your plugin that cause the 502 error.
I've put this code
if (!is_main_site(get_current_blog_id())){ return; }
in multisite-clone-duplicator.php on line 20, and now the error disappears and I can login in admin area of each site!
Is this fix ok?

I've cloned a new site, after this fix, and it seems to be ok!
Let me know if it's a right fix.

(The wordpres MU is in docker with nginx)

User roles & capabilities are exponentially duplicated

When we are duplicating sites and I looked in usermeta table I advice data is duplicating exponentially for each duplication.

Example:

Duplicate Main site to site2:

y5dwg245el_2_capabilities

Duplicate Main site to site3:

y5dwg245el_3_capabilities
y5dwg245el_3_2_capabilities

Duplicate Main site to site4:

y5dwg245el_4_capabilities
y5dwg245el_4_3_capabilities
y5dwg245el_4_3_2_capabilities

If you need more info, let me know.
