我发布了article 关于这一点,不久前:
function wp_trim_all_excerpt($text) {
// Creates an excerpt if needed; and shortens the manual excerpt as well
global $post;
$raw_excerpt = $text;
if ( \'\' == $text ) {
$text = get_the_content(\'\');
$text = strip_shortcodes( $text );
$text = apply_filters(\'the_content\', $text);
$text = str_replace(\']]>\', \']]>\', $text);
}
$text = strip_tags($text);
$excerpt_length = apply_filters(\'excerpt_length\', 55);
$excerpt_more = apply_filters(\'excerpt_more\', \' \' . \'[...]\');
$text = wp_trim_words( $text, $excerpt_length, $excerpt_more );
return apply_filters(\'wp_trim_excerpt\', $text, $raw_excerpt);
}
remove_filter(\'get_the_excerpt\', \'wp_trim_excerpt\');
add_filter(\'get_the_excerpt\', \'wp_trim_all_excerpt\');
