Send CF7 to Dynamic Email

I wanted to use the clients existing Contact Form 7 WordPress plugin. Each Cardiology member has their own profile page. Their email is in a native custom field. I wanted to send the contact form to each individual member. To do this I would have to dynamically populate the To: field with the email address from the custom field. I worked on this for hours before consulting Stack Overflow.

Within the contact form, it doesn’t let you get the $post->ID of the parent post. This data is stored in the form’s meta. It’s a hidden field passed in the form.

If you inspect your form from the front end, you’ll see this For example:
< input type=”hidden” name=”_wpcf7_container_post” value=”2730″ >
To get this, you access the $submission->get_meta(‘$value’) method.

This will work for you, given that the women_email is properly formatted as an email address. Also note that before_send_mail is an “ACTION” and not a “FILTER”

This worked in my functions.php file:

function wpcf7_before_send_mail_function($contact_form, &$abort, $submission){
    // This gets your post_id 
    $post_id = $submission->get_meta('container_post_id');
    $properties = $contact_form->get_properties();
    $properties['mail']['recipient'] = get_post_meta( $post_id, 'women_email', true);
    $contact_form->set_properties($properties);
}
add_action( 'wpcf7_before_send_mail', 'wpcf7_before_send_mail_function', 10, 3 );
