Add social icons to footer widget (not socket)

yes this will work – if you like to have a real widget you can do this to
functions.php of your child-theme:

function social_bookmarks_register_widget() {
register_widget( 'add_social_bookmarks' );
}
add_action( 'widgets_init', 'social_bookmarks_register_widget' );

class add_social_bookmarks extends WP_Widget {
public function __construct() {
  $widget_ops = array(
    'classname' => 'socialbookmarks-widget', 
    'description' => __('A widget that displays the social bookmarks', 'avia_framework') 
    );
  parent::__construct( 'add_social_bookmarks', THEMENAME.' Social Bookmarks', $widget_ops );
}

public function widget( $args, $instance ) {
  $title = apply_filters( 'widget_title', $instance['title'] );
  echo $args['before_widget'];
  //if title is present
  if ( ! empty( $title ) )
  echo $args['before_title'] . $title . $args['after_title'];
  //output
  echo $before_widget;
  $social_args = array('outside'=>'ul', 'inside'=>'li', 'append' => '');
  echo avia_social_media_icons($social_args, false);
  echo $after_widget;
}

public function form( $instance ) {
  if ( isset( $instance[ 'title' ] ) )
  $title = $instance[ 'title' ];
  else
  $title = __( 'Social Bookmarks', 'avia_framework' );
  ?>
  <p>
  <label for="<?php echo $this->get_field_id( 'title' ); ?>"><?php _e( 'Title:' ); ?></label>
  <input class="widefat" id="<?php echo $this->get_field_id( 'title' ); ?>" name="<?php echo $this->get_field_name( 'title' ); ?>" type="text" value="<?php echo esc_attr( $title ); ?>" />
  </p>
  <?php
}

public function update( $new_instance, $old_instance ) {
  $instance = array();
  $instance['title'] = ( ! empty( $new_instance['title'] ) ) ? strip_tags( $new_instance['title'] ) : '';
  return $instance;
}
}

and this to quick css:

#top .socialbookmarks-widget .social_bookmarks {
    float: left;
    margin: 15px 0 0 ;
    position: relative;
}

#top .socialbookmarks-widget .social_bookmarks li {
    float: left;
    clear: right !important;
}

you will have than a social bookmark widget.
it shows all of your scocial bookmarks from the options dialog of enfold. – You have the choice to give it a heading like on every other widget .
