<h3>Integrate with Contact Form 7</h3>
Bin Opt-In works best with contact form seven. To integrate it into your contact forms, you need to add custom code like this to your theme functions.php.
<pre>add_action('wpcf7_before_send_mail', 'bin_opt_in_contact');
function bin_opt_in_contact($cf7)
{
 // Get current form id
 $formId = $cf7->id;

 // Array of form ids
 $forms = [159, 454];

 // Only apply to certain forms
 if(in_array($formId, $forms))
 {
 // Dont do anything if class is missing
 if(class_exists('BinOptIn'))
 {
 // At least, the email must be present
 if(is_email($_POST['email']))
 {
 // map salutation
 $salutationMap = [ 
 'Frau' => 0,
 'Madame' => 0,
 'Mrs' => 0,
 'Herr' => 1,
 'Monsieur' => 1,
 'Mr' => 1,
 '*' => 2
 ];

 // assign form data with corresponding meta fields
 $postdata = [];
 $postdata['email'] = sanitize_email($_POST['email']);
 $postdata['first_name'] = sanitize_text_field($_POST['first_name']);
 $postdata['last_name'] = sanitize_text_field($_POST['last_name']);
 $postdata['salutation'] = $salutationMap[$_POST['salutation']];
 $postdata['terms_and_conditions_accepted'] = isset($_POST['terms_and_conditions_accepted']) ? 'yes' : '';

 // save contact
 BinOptIn::optIn($postdata, [
 'opt_in_admin_message' => false,
 'double_opt_in' => false,
 'admin_unlock' => false,
 'unlock_message' => false
 ]);
 }
 }
 }
}</pre>
<h3>Integrate with Contact Form 7 Multi-Step Pro</h3>
Save form data at every step by using the filter wpcf7_validate.
<pre>
add_filter('wpcf7_validate', 'save_contact_step', 10, 2);
function save_contact_step($result, $tags)
{
 // Get current form id
 $formId = $_POST['_wpcf7'];

 // Array of form ids
 $forms = [159, 454];

 // Only apply to certain forms
 if(in_array($formId, $forms))
 {
 // Dont do anything if class is missing
 if(class_exists('BinOptIn'))
 {
 // save contact info here
 // BinOptIn::optIn()
 }
 }

 return $result;
}
</pre>

Opt-In

Tobiask

Allows readers to receive notifications of new comments that are posted to an entry, after they successfully used the mandatory double-opt-in process to verify their e-mail address. 
First, the user will get an e-mail with a confirmation link, after the user has confirmed the subscription, he or she will be noticed about new comments. This reduces junk and other unwanted e-mail communication. 
This plugin is based on Mark Jaquith´s “Subscribe to Comments” plugin. More information on my blog: <a href="https://sjmp.de/internet/subscribe-to-comments-mit-double-opt-in-pruefung/" rel="nofollow ugc">sjmp.de</a>.
