I would like to remove the [...] from the RSS feed widget.

I have tried adding the following to functions:

function replace_ellipsis($text) {

$return = str_replace('[...]', '-', $text);
 return $return;
add_filter('get_the_excerpt', 'replace_ellipsis');

However, this does not affect the widget.

Any help?

    have you tried to use 'the_excerpt_rss' filter? or … in the string replace?

Here's a suggestion:

  • First we target the RSS widgets that have summaries.
  • Then we filter the output of wp_trim_words() within the wp_widget_rss_output() function, to remove the […] part.

Then we clean up in two ways:

  • First we remove our wp_trim_words() filter, if it's running, before the current widget is displayed. We can do that by hooking into widget_display_callback. That means our filter callback will not be active in the next widget.

  • Then we remove the filter callback, if it's running, after the sidebar through the dynamic_sidebar_after hook. This means the filter callback will be removed after the dynamic sidebar. That could e.g. be useful if we only have a single widget in the dynamic sidebar.

Here's the demo plugin:

add_filter( 'widget_display_callback', function( $instance, $obj, $args )
    // Cleanup before each widget
    if( has_filter( 'wp_trim_words', 'wpse_replace_hellip' ) ) 
        remove_filter( 'wp_trim_words', 'wpse_replace_hellip' );

    // Target RSS widgets with summary
           'rss' === $obj->id_base 
        && isset( $instance['show_summary'] ) 
        && 1 == $instance['show_summary'] 
    ) {
        // Replace the […] part
        add_filter( 'wp_trim_words', 'wpse_replace_hellip' );
        // Clean up after dynamic sidebar
        add_filter( 'dynamic_sidebar_after', 'wpse_extra_cleanup' );
    return $instance;
}, 10, 3 );

function wpse_replace_hellip( $text )
    if ( ' […]' == substr( $text, -11 ) )
        $text = substr( $text, 0, -11 );
    return $text;

function wpse_extra_cleanup()
    remove_filter( current_filter(), __FUNCTION__ );
    remove_filter( 'wp_trim_words', 'wpse_replace_hellip' );    

Hope you can test further and adjust to your needs!


The body of the default RSS widget is generated by the function wp_widget_rss_output. As you can see in the source, the [...] is hardwired into the code and echoed directly. There is no filter for straightforward manipulation of the feed output.
