您需要使用来钩住WordPress的清理标题钩子。

function no_dashes($title) {
    return str_replace(\'-\', \'\', $title);
}
add_filter(\'sanitize_title\', \'no_dashes\' , 9999);

function no_dashes( $slug, $post_ID, $post_status, $post_type ) {

    if( $post_type == "page" ) {
        $slug = str_replace( \'-\', \'\', $slug);
    }
    return $slug;
}
add_filter( "wp_unique_post_slug", "no_dashes", 10, 4 );
