In EE 2.1.3 I am trying to use a single checkbox in a contact form. All other fields in the form are working but the checkbox yields no results in the sent emails. Here is the code I am using (abbreviated to protect the innocent):
{exp:email:contact_form user_recipients="false" recipients="[email protected]" charset="utf-8"}
<label for="from">your email address:</label>
<input type="text" id="from" name="from" size="40" maxlength="35" value="" /></p>
<label for="message">message:</label>
<textarea id="message" name="message" rows="12" cols="54"></textarea>
<input type="checkbox" name="add_to_mailing_list" value="yes"> <label for="add_to_mailing_list">add me to the CR Guitars mailing list </label>
<input name="submit" type='submit' value='Submit Form' /></p>
{/exp:email:contact_form}Resulting emails contain only the message, no checkbox response (whether checked or not). Any ideas?
