Introduction
MailChimp Subscribe for Craft is a plugin for subscribing to a MailChimp newsletter list., (*1)
MailChimp Subscribe requires PHP 5.5 or later., (*2)
Installation
- Download and extract the contents of the zip. Put the
mailchimpsubscribe folder to your Craft plugin folder.
- Enable the MailChimp Subscribe plugin in Craft (Settings > Plugins).
- Configure the plugin either in the plugin settings page in the control panel, or configure it via the general config file (see "Configuration" below).
- Add a form for signing up to your templates (see "Example Usage" below).
- Eat a banana.
Configuration
To use the plugin you need to create an API key from the MailChimp control panel, and create a list
(or use one that you already have)., (*3)
You can configure MailChimp Subscribe either through the plugins settings in the control panel, or
by adding the settings to the general config file (usually found in /craft/config/general.php).
Configuring it in the settings file is more flexible, since you can set up the config file to have
different settings depending on the environment., (*4)
Example
'mcsubApikey' => 'xxxxxxxxxxxxxxxxxxxxx-us2',
'mcsubListId' => '2fd6ec09cf',
'mcsubDoubleOptIn' => false
If you have multiple lists you want users to subscribe to, each form can have a hidden field with a name
of "lid" and the "value" as your list id. The plugin will use this list id on form submit., (*5)
Example
<input type="hidden" name="lid" value="2fd6ec09cf">
If you want to subscribe to several lists from the same form, you can send in several list id's as a piped list., (*6)
Example
<input type="hidden" name="lid" value="2fd6ec09cf|5fe66521c0">
Example Usage
The following example shows the plugin in use:, (*7)
<form class="newsletter-form" action="" method="POST">
{{ getCsrfInput() }}
<input type="hidden" name="action" value="mailchimpSubscribe/list/subscribe">
<input type="hidden" name="redirect" value="newsletter/receipt">
{% if mailchimpSubscribe is defined %}
{% if (not mailchimpSubscribe.success) and (mailchimpSubscribe.errorCode!='1000') %}
<p>An error occured. Please try again.</p>
{% endif %}
{% endif %}
<div class="field-line">
<label>First name:</label>
<input type="text" name="mcvars[FNAME]" value="{% if (mailchimpSubscribe is defined) and (not mailchimpSubscribe.success) %}{{ mailchimpSubscribe.values.vars.FNAME }}{% endif %}"/>
</div>
<div class="field-line">
<label>Last name:</label>
<input type="text" name="mcvars[LNAME]" value="{% if (mailchimpSubscribe is defined) and (not mailchimpSubscribe.success) %}{{ mailchimpSubscribe.values.vars.LNAME }}{% endif %}"/>
</div>
<div class="field-line">
<label{% if (mailchimpSubscribe is defined) and (mailchimpSubscribe.errorCode=='1000') %} class="error"{% endif %}>Email:</label>
<input type="text" name="email" value="{% if (mailchimpSubscribe is defined) and (not mailchimpSubscribe.success) %}{{ mailchimpSubscribe.values.email }}{% endif %}"/>
</div>
<input type="submit" name="" value="Subscribe"/>
</form>
This code assumes that you have a template path newsletter/receipt which the user is redirected to upon
successfully signing up to MailChimp. If you want to display the receipt message inside the same template,
you just obmit the redirect parameter:, (*8)
<form class="newsletter-form" action="" method="POST">
{{ getCsrfInput() }}
<input type="hidden" name="action" value="mailchimpSubscribe/list/Subscribe">
{% if mailchimpSubscribe is defined %}
{% if (not mailchimpSubscribe.success) and (mailchimpSubscribe.errorCode!='1000') %}
<p>An error occured. Please try again.</p>
{% endif %}
{% if mailchimpSubscribe.success %}
<p>Thank you for signing up!</p>
{% endif %}
{% endif %}
<div class="field-line">
<label>First name:</label>
<input type="text" name="mcvars[FNAME]" value="{% if (mailchimpSubscribe is defined) and (not mailchimpSubscribe.success) %}{{ mailchimpSubscribe.values.vars.FNAME }}{% endif %}"/>
</div>
<div class="field-line">
<label>Last name:</label>
<input type="text" name="mcvars[LNAME]" value="{% if (mailchimpSubscribe is defined) and (not mailchimpSubscribe.success) %}{{ mailchimpSubscribe.values.vars.LNAME }}{% endif %}"/>
</div>
<div class="field-line">
<label{% if (mailchimpSubscribe is defined) and (mailchimpSubscribe.errorCode=='1000') %} class="error"{% endif %}>Email:</label>
<input type="text" name="email" value="{% if (mailchimpSubscribe is defined) and (not mailchimpSubscribe.success) %}{{ mailchimpSubscribe.values.email }}{% endif %}"/>
</div>
<input type="submit" name="" value="Subscribe"/>
</form>
Any other list variables you have configured in MailChimp can be added with formfields with name values like mcvars[YOURMCVAR]., (*9)
You can also unsubscribe an email from a list by using the mailchimpSubscribe/list/unsubscribe controller action. Example:, (*10)
<form class="newsletter-form" action="" method="POST">
{{ getCsrfInput() }}
<input type="hidden" name="action" value="mailchimpSubscribe/list/unsubscribe">
<input type="hidden" name="redirect" value="newsletter/receipt">
{% if mailchimpSubscribe is defined %}
{% if (not mailchimpSubscribe.success) and (mailchimpSubscribe.errorCode!='1000') %}
<p>An error occured. Please try again.</p>
{% endif %}
{% endif %}
<div class="field-line">
<label{% if (mailchimpSubscribe is defined) and (mailchimpSubscribe.errorCode=='1000') %} class="error"{% endif %}>Email:</label>
<input type="text" name="email" value="{% if (mailchimpSubscribe is defined) and (not mailchimpSubscribe.success) %}{{ mailchimpSubscribe.values.email }}{% endif %}"/>
</div>
<input type="submit" name="" value="Unubscribe"/>
</form>
The mailchimpSubscribe object
When the plugin returns to the origin template, either if an error occured or successfully posting without a redirect, it will return
a mailchimpSubscribe object to the template. It contains the following variables:, (*11)
mailchimpSubscribe.success (Boolean): True or false, depending on if the Subscribe was completed successfully or not., (*12)
mailchimpSubscribe.errorCode (Number): If an error occured, an error code will also be supplied. See below for a list., (*13)
mailchimpSubscribe.message (String): A message describing the error. This probably shouldn't be displayed to end users, you should display your own depending on error code., (*14)
mailchimpSubscribe.values (Object): A structure containing the values that were submitted. For instance mailchimpSubscribe.values.email and mailchimpSubscribe.values.vars.FNAME., (*15)
If you submit multiple list ids are submitted, the mailchimpSubscribe object will contain a listResults array containing the results for each list. If an error occured for one of the lists, the base object will contain the error., (*16)
Ajax submitting
If the form is submitted with Ajax, the plugin will return a JSON object with the same keys as the template object described above. Big up to Jake Chapman for implementing this. :), (*17)
Example:, (*18)
$('form').on("submit", function(event) {
event.preventDefault();
$.post('/', $(this).serialize())
.done( function(data) {
if (!data.success)
{
// there was an error, do something with data
alert(data.message);
}
else
{
// Success
alert("WEEEEEEEEEE");
}
});
});
Groups
Groups can be added by adding a interests key to mcvars, as an array of interest ids that the user wants to add. You can get the
interests connected to a list with the template variable getListInterestGroups. MailChimp lets you create different types of groups,
checkboxes, radio buttons, dropdown, etc, but doesn't actually limit the add functionality to the groups depending on the type. You have
to do this based on the group type. Example:, (*19)
<form class="newsletter-form" action="" method="POST">
{{ getCsrfInput() }}
<input type="hidden" name="action" value="mailchimpSubscribe/list/subscribe">
{% if mailchimpSubscribe is defined %}
{% if (not mailchimpSubscribe.success) and (mailchimpSubscribe.errorCode!='1000') %}
<p>An error occured. Please try again.</p>
{% endif %}
{% if mailchimpSubscribe.success %}
<p>Thank you for signing up!</p>
{% endif %}
{% endif %}
<div class="field-line">
<label>First name:</label>
<input type="text" name="mcvars[FNAME]" value="{% if (mailchimpSubscribe is defined) and (not mailchimpSubscribe.success) %}{{ mailchimpSubscribe.values.vars.FNAME }}{% endif %}"/>
</div>
<div class="field-line">
<label>Last name:</label>
<input type="text" name="mcvars[LNAME]" value="{% if (mailchimpSubscribe is defined) and (not mailchimpSubscribe.success) %}{{ mailchimpSubscribe.values.vars.LNAME }}{% endif %}"/>
</div>
<div class="field-line">
<label{% if (mailchimpSubscribe is defined) and (mailchimpSubscribe.errorCode=='1000') %} class="error"{% endif %}>Email:</label>
<input type="text" name="email" value="{% if (mailchimpSubscribe is defined) and (not mailchimpSubscribe.success) %}{{ mailchimpSubscribe.values.email }}{% endif %}"/>
</div>
{% set interestGroups = craft.mailchimpSubscribe.getListInterestGroups(craft.config.mcsubListId) %}
{% if not interestGroups.success %}
{{ interestGroups.message }}<br>
{% endif %}
{% if interestGroups.success and (interestGroups.groups | length > 0) %}
{% for group in interestGroups.groups %}
<strong>{{ group.title }}</strong>
<br>
{% if group.type=='checkboxes' %}
{% for interest in group.interests %}
<input type="checkbox" value="{{ interest.id }}" name="mcvars[interests][]">{{ interest.name }}<br>
{% endfor %}
{% endif %}
{% if group.type=='radio' %}
{% for interest in group.interests %}
<input type="radio" value="{{ interest.id }}" name="mcvars[interests][]">{{ interest.name }}<br>
{% endfor %}
{% endif %}
{% if group.type=='dropdown' %}
<select name="mcvars[interests][]">
{% for interest in group.interests %}
<option value="{{ interest.id }}">{{ interest.name }}</option>
{% endfor %}
</select>
{% endif %}
{% endfor %}
{% endif %}
<input type="submit" name="" value="Subscribe"/>
</form>
Checking if an email is already on a list
Sometimes you might want to know if a user is already on an email list - for example during a cart checkout. It's nice not to bother your existing customers with repeated requests to subscribe to your mailing list, so if this check shows they're already subscribed, you can hide your subscribe form., (*20)
You can either use the template variable checkIfSubscribed like this:, (*21)
{% set checkResponse = craft.mailchimpSubscribe.checkIfSubscribed('email@domain.com', 'mylistid') %}
{% if checkResponse.success %}
Email is on list!
{% else %}
Email is NOT on list!
{% endif %}
Or, you can use the controller action. Here's an example that should get you started implementing such behaviour:, (*22)
<p>Check if a user is on our mailing list</p>
<form method="POST" id="testMCOnList">
{{ getCsrfInput() }}
<input type="hidden" name="action" value="mailchimpSubscribe/list/CheckIfSubscribed">
Enter email to check: <input type="text" id="email" size="40" name="email" >
<input type="submit" class="btn" value="Check if subscribed">
</form>
<h3> Results: </h3>
<span id="results"></span>
And some jquery to do the actual check:, (*23)
$('#testMCOnList').on('submit', function(e) {
e.preventDefault();
$.ajax({
type: 'POST',
url: '',
data: $(this).serialize(),
success: function( response ) {
if(response.success){
$('#results').html("On List");
//hide your form here
//Also, response.vars.subscriberInfo will contain a bunch of info about the user should you want it
}
else{
$('#results').html("Not On List");
//display your subscribe form here
}
},
});
});
Error codes
1000: Missing or invalid email.
2000: Missing API key or List ID., (*24)
Any other codes are API errors, and the same code that the MailChimp API returned. Refer to MailChimp's documentation., (*25)
