Frequently Asked Questions

Common questions about MC4WP: Mailchimp Top Bar – Email Subscribe Notification Bar

Yes. Use the mctb_show_bar filter to control where the bar appears. This example shows it on blog posts only: add_filter( 'mctb_show_bar', function( $show ) { return is_single(); } ); This example shows it only on the contact page: add_filter( 'mctb_show_bar', function( $show ) { return is_page( 'contact' ); } ); See the WordPress Conditional Tags documentation for other conditions.

Yes. Add a name field and pass its value to the selected Mailchimp audience: add_action( 'mctb_before_submit_button', function() { echo '<input type="text" name="NAME" placeholder="Your name" />'; } ); add_filter( 'mctb_subscriber_data', function( $subscriber ) { if ( ! empty( $_POST['NAME'] ) ) { $subscriber->merge_fields['NAME'] = sanitize_text_field( $_POST['NAME'] ); } return $subscriber; } ); See adding a name field to Mailchimp Top Bar for more details.

Add this CSS to hide the bar on screens narrower than 600 pixels: @media ( max-width: 600px ) { #mailchimp-top-bar { display: none !important; } }

The plugin keeps its front-end footprint small. Its JavaScript is under 2 kB when compressed, and the stylesheet loads without blocking page rendering.
