MC4WP: Mailchimp Top Bar – Email Subscribe Notification Bar

FAQ

Can I show the Mailchimp top bar on specific pages only?

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.

Can I capture names in the notification bar?

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.

How can I hide the email signup bar on mobile devices?

Add this CSS to hide the bar on screens narrower than 600 pixels:

@media ( max-width: 600px ) {
    #mailchimp-top-bar {
        display: none !important;
    }
}

Does Mailchimp Top Bar affect site performance?

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