How to Display a Call-to-action when a Specific Product is Added to the Cart?

If you want to trigger a call-to-action when a specific product is added to the cart, you just need to add the following code snippet in your theme’s functions.php file.

add_filter( 'cp_pro_target_page_settings', 'cp_is_display_popup', 10, 2 );

function cp_is_display_popup( $display_style, $style_id ) {
     // if style is to display on this page ( replace 7 with your style id ) 
     if( $display_style && 7 == $style_id ) {
         global $woocommerce;
         $display_style = false;
         foreach( $woocommerce->cart->get_cart() as $key => $val ) { 
             $_product = $val['data']; 
             // replace 10 with your product id
             if( 10 == $_product->get_id() ) {
                 // display style
                 $display_style = true;    
             }  
         }  
     }
     return $display_style;
 }
