MailChimp List Subscribe Form Plugin

Use the MailChimp List Subscribe plugin to quickly add a MailChimp signup form widget to your WordPress 2.8 or higher site.

After installation, you’ll log in with your API key, select your MailChimp list, choose merge fields and groups, and add the widget to your site. Typically, installation and setup will take about 5-10 minutes, and absolutely everything can be done via the WordPress Setting GUI, with no file editing at all.

WordPress.com compatibility is limited to Business tier users only. How to add a signup form if you have a WordPress.com site.

Upgrading

If you are upgrading to version 1.2.1 and you used the widget in your sidebar previously, all you need to do is drag the MailChimp Widget back into the sidebar, visit the MailChimp settings page (which will have maintained your prior settings), click the “Update List” button, and you’re done!

If your language is not listed above, feel free to create a translation. Here are the basic steps:

1. Copy “mailchimp_i18n-en_US.po” to “mailchimp_i18n-LANG_COUNTRY.po” – fill in LANG and COUNTRY with whatever you use for WPLANG in wp-config.php
2. Grab a transalation editor. POedit works for us
3. Translate each line – if you need some context, just open up mailchimp.php and search for the line number or text
4. Fork the repository on github
5. Clone the develop branch
6. Add the appropriately named files to the /po/ directory and edit the /readme.txt to include how you’d like to be attributed
7. Make a pull request

Advanced

If you have a custom coded sidebar or bells and whistles that prevent enabling widgets through the WordPress GUI, complete these steps instead.

WordPress v2.8 or higher:
[mailchimpsf_form]

If you are adding it inside a php code block, pop this in:

 mailchimpSF_signup_form(); 

Or, if you are dropping it in between a bunch of HTML, use this:

<?php mailchimpSF_signup_form(); ?> 

Where ever you want it to show up.

Note: in some environments you will need to install the Exec_PHP plugin to use that method of display. It can be found here: https://wordpress.org/extend/plugins/exec-php/
