The MailChimpForms extension allows the insertion of MailChimp forms easy on your wiki. Currently it only supports the sign-up form, but should be easy to add more functionality if you're interested in doing so.


Insert a form using the new tag <mailchimpforms> using these parameters.

Required parametersEdit

  • prefix: the text that comes before us1.list-manage.com in the URLs that MailChimp uses to manage your lists (usually it is the name of your organization, all lower-case, no spaces)
  • account: your 24-character account id with MailChimp. You can get this by looking at the sign-up form code that MailChimp provides you, and looking for the parameter u=xxxxxxxxxxxxxxxxxxxxxxx
  • list: the 10-character id of the list you want the form to work with, found in the same place as the account id above
  • type: the type of form to insert, which right now can only be set to subscribe

Optional parametersEdit

  • bordercss: if you want to customize the border around your form, enter the code here, e.g. 1px solid black
  • closelink: set to true if you want the "Close" link to appear under your form


This following code will insert a form for a Mediawiki mailing list (fictional) with no border and no "Close" link:

<mailchimpforms prefix="mediawiki" account="abcdefghijklmnopqrstuvwx" list="0123456789" type="subscribe" />


  • Add the following code at the bottom of your LocalSettings.php:
    require_once "$IP/extensions/MailChimpForms/MailChimpForms.php";
  •   Done – Navigate to Special:Version on your wiki to verify that the extension is successfully installed.
