使用twitter bootsrap，如果在同一位置有更多的小部件，我想对我的小部件进行网格化。我的意思是：拥有一个注册的小部件

register_sidebar(array(
    \'name\' => __(\'Footer Top\', \'roots\'),
    \'id\' => \'footer-top\',
    \'before_widget\' => \'<div class="footer_teaser %1$s %2$s">\',
    \'after_widget\' => \'</div>\',
    \'before_title\' => \'<h3>\',
    \'after_title\' => \'</h3>\',
));

如何计算和循环列中的所有小部件？假设理论上，我在给定位置有3个（这是可变的）小部件，而不是将其拆分为12/3（或另一个已计数），这将为我提供上述示例footer_teaser col-sm-4 col-md-4

比预期的结果会产生

<div class="footer_teaser col-sm-4 col-md-4">
                    <h3>About us</h3>
                    <p>Fugiat dapibus, tellus ac cursus commodo, mauesris condime ntum nibh, ut fermentum mas justo sitters.</p>
                    <p><i class="fa fa-map-marker"></i> 3 Athens street</p>
                    <p><i class="fa fa-phone"></i> (+30) 265-9987</p>
                    <p><i class="fa fa-print"></i> (+30) 9854-7855</p>
                    <p><i class="fa fa-envelope"></i> [email protected]</p>
</div>

到目前为止，我在计算小部件时发现了什么

function count_sidebar_widgets($sidebar_id, $echo = true) {
    $the_sidebars = wp_get_sidebars_widgets();
    if (!isset($the_sidebars[$sidebar_id]))
        return __(\'Invalid sidebar ID\');
    if ($echo)
        return 12 / count($the_sidebars[$sidebar_id]);
    else
        return count($the_sidebars[$sidebar_id]);
}

比我这一代人

register_sidebar(array(
    \'name\' => __(\'Footer Top\', \'roots\'),
    \'id\' => \'footer-top\',
    \'before_widget\' => \'<div class="footer_teaser col-lg-\'.count_sidebar_widgets(\'footer-top\').\'">\',
    \'after_widget\' => \'</div>\',
    \'before_title\' => \'<h3>\',
    \'after_title\' => \'</h3>\',
));

但我不满意

   register_sidebar(array(
    \'name\' => __(\'Footer Top\', \'roots\'),
    \'id\' => \'footer-top\',
    \'before_widget\' => \'<div class="footer_teaser %1$s %2$s col-sm-4 col-md-4">\',
    \'after_widget\' => \'</div>\',
    \'before_title\' => \'<h3>\',
    \'after_title\' => \'</h3>\',
   ));
