您需要捕获传递给短代码的属性。你可以这样做

add_shortcode(\'testimonial\', \'testimonial_shortcode_func\');
function testimonial_shortcode_func( $atts ) {
    $atts = shortcode_atts( array(
      \'style\' => \'default_value_if_no_value_is_provided\',
    ), $atts );

    if( $atts[\'style\'] == \'fancy\' ) {
        //do something
    } else if ( $atts[\'style\'] == \'something_else\' ) {
        //do something
    }
    //And so on
    //finally return content, don\'t echo just return
}
