I have the follow code:

if ( !function_exists( 'df_excerpt_more' ) ) {

   function df_excerpt_more( $more ) {
       return ' &hellip; <a class="more-link" href="' . esc_url( get_permalink( get_the_ID() ) ) . '">' . esc_attr__( 'Read More', 'applique' ) . '<i class="ion-ios-arrow-thin-right"></i></a>';
   }

   add_filter( 'excerpt_more', 'df_excerpt_more' );

}

I’d like to add a second line of “add_filter” and execute it only if page is home. So I’m trying this:

if ( !function_exists( 'df_excerpt_more' ) ) {

   function df_excerpt_more( $more ) {
       return ' &hellip; <a class="more-link" href="' . esc_url( get_permalink( get_the_ID() ) ) . '">' . esc_attr__( 'Read More', 'applique' ) . '<i class="ion-ios-arrow-thin-right"></i></a>';
   }

   add_filter( 'excerpt_more', 'df_excerpt_more' );

   //second filter if is home like this:
   if ( is_home() ) :
     add_filter('get_the_excerpt', 'df_excerpt_more');
   endif;

}

For some reason this isn’t working. Seems like something very simple. What am I missing?
