## Description

Use the Mailchimp List Subscribe plugin to quickly add a Mailchimp signup form block,
widget, or shortcode to your WordPress site.

After installation, if you already have a Mailchimp account, you’ll log in with 
that account and then proceed to configure settings.

If you don’t have an account, you can create one directly in the plugin. After entering
in all your personal details, you’ll need to activate your account via an email 
that will be sent to you. Once done, you’ll proceed to configure settings.

On the settings screen, you’ll select your Mailchimp list, choose merge fields and
groups, and configure other options. Once done, you can now add the block, widget,
or shortcode (`[mailchimpsf_form]`) 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](https://mailchimp.com/help/ways-to-add-a-signup-form-in-wordpress/).

### Access Token Encryption

Starting in version 1.6.0, authentication has changed to use OAuth. As part of this
process, we retrieve an access token that can be used to make API requests. To provide
a high-level of security, this access token is encrypted before being stored in 
the WordPress database. In order to ensure this access token can be decrypted when
used, the plugin relies on certain security constants that should remain unchanged.

With no additional configuration, we use the standard `LOGGED_IN_KEY` and `LOGGED_IN_SALT`
constants that are normally set in your site’s `wp-config.php` file. Some sites 
make use of security plugins that rotate these constants on a periodic basis. When
this happens, we won’t be able to decrypt the access token and you’ll need to reconnect
your Mailchimp account to generate a new access token.

To prevent such issues, it is recommended to define two additional constants in 
your site’s `wp-config.php` file: `MAILCHIMP_SF_ENCRYPTION_KEY` and `MAILCHIMP_SF_ENCRYPTION_SALT`.
These constants should consist of a combination of characters, preferably at least
32 characters long. Once set, these values should not be changed. For strong values,
you can copy some of the values from [here](https://api.wordpress.org/secret-key/1.1/salt/)
and use them. You’ll end up with additional code like the following in your `wp-
config.php` file:

    ```
    define( 'MAILCHIMP_SF_ENCRYPTION_KEY', 'put your unique phrase here' );
    define( 'MAILCHIMP_SF_ENCRYPTION_SALT', 'put your unique phrase here' );
    ```

If these constants are added after you’ve already authenticated with Mailchimp, 
you will need to reconnect your account. To avoid this, you can copy the values 
from `LOGGED_IN_KEY` and `LOGGED_IN_SALT` (if they exist) to `MAILCHIMP_SF_ENCRYPTION_KEY`
and `MAILCHIMP_SF_ENCRYPTION_SALT` respectively.

### 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!

## FAQ

### Why am I not seeing all my fields in my form?

You need to ensure that the fields are enabled both in your Mailchimp account (Audience
> Signup forms) and in the settings of this plugin. Once the fields are enabled 
in both places, then they’ll appear in the editor and frontend of your site.

We have been using this for years on a number of sites, but recently we came across
a problem that the fields in Mailchimp set up and appearance on the website did 
not match. Our own fix was being overwritten by plug-in update, so we had to repeat
the fix on every website every time we updated the plug-in We reported this to the
Author and they came back the next day with a solution. Great support and very happy.

The plugin is a complete joke and injects js that is abysmal.

Why has this plugin been abandoned? A company of MailChimp’s size can easily afford
to maintain this WordPress plugin. Either support the plugin or delete it.
