E&T Filter: General Filter

Excerpts & Thumbnails' options can be overwritten by filters. Let’s consider an example. 

As you can see below, the  word_limit option that is set in the backend is being overridden. 

add_filter('wprss_template_extra_options', 'my_wprss_template_extra_options', 11, 3);

function my_wprss_template_extra_options($options, $args) {
    $options['word_limit'] = 20; // Limit excerpts output to 20 words
    return $options;
}

Other options that can be overridden this way include:

• excerpts_enabled  -  Corresponds to the Enable excerpts option;
• excerpts_ending  -  Corresponds to the Excerpts ending option;
• excerpts_more_link_enabled  -  Corresponds to the Enable "Read more link" option;
• excerpts_read_more  -  Corresponds to the Read more text option.
