如何在主题激活的自定义侧边栏中插入自定义小工具？

时间：2017-03-01 作者：Archangel17

我已经创建了一个自定义小部件，我希望它能插入到我想要的关于主题激活的任何侧栏中。有可能吗？

顺便说一句，这是我用于侧边栏的代码

function awesome_register_sidebars() {
    register_sidebar(
        array(
            \'id\' => \'sidebar-footer-1\',
            \'name\' => __( \'Footer Nav  Links 1\', \'Awesome\' ),
            \'description\' => __( \'A short description of the sidebar.\', \'Awesome\' ),
            \'before_widget\' => \'<div class="footer-link">\',
            \'after_widget\' => \'</div>\',
            \'before_title\' => \'<h3 class="footer-link-head">\',
            \'after_title\' => \'</h3>\'
                ));
register_sidebar(
        array(
            \'id\' => \'sidebar-footer-2\',
            \'name\' => __( \'Footer Nav Links 2\', \'Awesome\' ),
            \'description\' => __( \'A short description of the sidebar.\', \'Awesome\' ),
            \'before_widget\' => \'<div class="footer-link">\',
            \'after_widget\' => \'</div>\',
            \'before_title\' => \'<h3 class="footer-link-head">\',
            \'after_title\' => \'</h3>\'
                ));
register_sidebar(
        array(
            \'id\' => \'sidebar-footer-3\',
            \'name\' => __( \'Footer Nav  Links 3\', \'Awesome\' ),
            \'description\' => __( \'A short description of the sidebar.\', \'Awesome\' ),
            \'before_widget\' => \'<div class="footer-link">\',
            \'after_widget\' => \'</div>\',
            \'before_title\' => \'<h3 class="footer-link-head">\',
            \'after_title\' => \'</h3>\'
                ));

但如果我们想在主题被激活时这样做，我们必须改变一些小事情。Changs maded done in function awesome\\u register\\u提要栏。在主题函数中添加以下代码。php文件：

function awesome_register_sidebars() {
      $sidebars = array ( \'a\' => \'sidebar-footer-1\', \'b\' => \'sidebar- footer-2\',\'c\'=>\'sidebar-footer-3\' );
foreach ($sidebars as $sidebar) {
    register_sidebar(
        array (
            \'name\'          => $sidebar,
            \'id\'            => $sidebar,
            \'before_widget\' => \'\',
            \'after_widget\'  => \'\'
        )
    );
}
$active_widgets = get_option(\'sidebars_widgets\');

if (! empty($active_widgets[ $sidebars[\'a\'] ])
    or ! empty($active_widgets[ $sidebars[\'b\'] ])
) {
    return;
}

$counter = 1;
$active_widgets[ $sidebars[\'a\'] ][0] = \'footerlinks_widget-\' . $counter;
$demo_widget_content[ $counter ] = array ( \'text\' => "This works!\\n\\nAmazing!" );

$counter++;


$active_widgets[ $sidebars[\'a\'] ][] = \'footerlinks_widget-\' . $counter;

$footerlinks_widget_content[ $counter ] = array ();
update_option(\'widget_footerlinks_widget\', $footerlinks_widget_content);

 $counter++;


   update_option(\'sidebars_widgets\', $active_widgets);
 }
add_action( \'widgets_init\', \'awesome_register_sidebars\' );
