如何在博客设计插件WordPress的摘录结束时3点

Hello Guys I used blog deisgner plugin. i just want to 3 dots after excerpt end means content words end in front. please tell me how to do that. Thanks

By default, the excerpt “read more” string at the end is set to '...' . To change the excerpt “read more” string using the excerpt_more filter add the following code to the functions.php file in your theme:

/**
 * Filter the excerpt "read more" string.
 *
 * @param string $more "Read more" excerpt string.
 * @return string (Maybe) modified "read more" excerpt string.
 */
function wpdocs_excerpt_more( $more ) {
    return '[.....]';
}
add_filter('excerpt_more', 'wpdocs_excerpt_more');
