问题描述

是否有检查小部件是否在当前前端显示的功能?
这是拉取一些样式或脚本或对小部件执行其他操作所必需的.

Is there a function to check if a widget is displayed in the current front end?
This is necessary for pulling some styles or scripts or doing other action to the widget.

推荐答案

请通过回显 $GLOBALS['displayed_sidebars'] 和 $GLOBALS['displayed_widgets'] 的内容来查看这是否有效，例如使用 print_r.

Please see if this works by echoing the contents $GLOBALS['displayed_sidebars'] and $GLOBALS['displayed_widgets'], using print_r for example.

必须在对要包含的所有侧边栏执行 dynamic_sidebar 后对其进行测试.

It must be tested after dynamic_sidebar has been executed for all sidebars that you want to include.

add_filter( 'dynamic_sidebar_params', function( $params ) {
    global $displayed_sidebars, $displayed_widgets;
    if( !in_array( $params[0]['id'], $displayed_sidebars ))
        $displayed_sidebars[] = $params[0]['id'];

    if( !in_array( $params[0]['widget_name'], $displayed_widgets ))
        $displayed_widgets[] = $params[0]['widget_name'];

    return $params;
});
