How to register multiple widgets correctly?

Hey guys,

I use the code below to register custom widget, add ACF fields to it and display everything on front-end.

class Custom_Widget extends WP_Widget {
  /**
   * Register widget with WordPress.
   */
  function __construct() {
    parent::__construct(
      'topbar_widget', // Base ID
      __('Topbar widget', 'domainname'), // Name
      array( 'description' => __( 'Email, phone, FB link', 'domainname' ), ) // Args
    );
  }

  /**
   * Front-end display of widget.
   *
   * @see WP_Widget::widget()
   *
   * @param array $args     Widget arguments.
   * @param array $instance Saved values from database.
   */
	 public function widget( $args, $instance ) {
     echo $args['before_widget'];
      echo $args['before_title'] . apply_filters( 'widget_title', $instance['title'] ). $args['after_title'];
 	    ?>
				<a class="top-email" href="mailto:[email protected]"><?php the_field('email_topbar', 'widget_' . $args['widget_id']); ?></a>
				<a class="top-phone" href="callto://12345678901234567890"><?php the_field('phone_topbar', 'widget_' . $args['widget_id']); ?></a>
				<a class="top-fb" href="<?php the_field('fb_topbar', 'widget_' . $args['widget_id']); ?>" target="_blank">Facebook</a>

			<?php
   }

  /**
   * Back-end widget form.
   *
   * @see WP_Widget::form()
   *
   * @param array $instance Previously saved values from database.
   */
  public function form( $instance ) {
    if ( isset($instance['title']) ) {
      $title = $instance['title'];
    }
    else {
      $title = __( 'New title', 'domainname' );
    }
    ?>

    <?php
  }

  /**
   * Sanitize widget form values as they are saved.
   *
   * @see WP_Widget::update()
   *
   * @param array $new_instance Values just sent to be saved.
   * @param array $old_instance Previously saved values from database.
   *
   * @return array Updated safe values to be saved.
   */
  public function update( $new_instance, $old_instance ) {
    $instance = array();
    $instance['title'] = ( ! empty( $new_instance['title'] ) ) ? strip_tags( $new_instance['title'] ) : '';

    return $instance;
  }

} // class Custom_Widget

// register Custom_Widget widget
add_action( 'widgets_init', function(){
  register_widget( 'Custom_Widget' );
});

This code works great, but I would like to register a few other widgets – the question is – do I repeat every line of above code for every single registered widget or can I add somehow the new custom widgets between the lines of above code without repeating a whole bunch of code?

Thanks.

I think you’ll need to change some items; I’ve marked them with “CHANGE_THIS”.
class CHANGE_THIS extends WP_Widget

function __construct() {
    parent::__construct(
      'CHANGE_THIS', // Base ID
      __('CHANGE_THIS', 'domainname'), // Name
      array( 'description' => __( 'Email, phone, FB link', 'domainname' ), ) // Args
    );
  }

add_action( 'widgets_init', function(){
  register_widget( 'CHANGE_THIS' );
});
