我正在使用Rockit Now wordpress主题，它带有一个音乐播放器小部件。将小部件添加到侧边栏时，您有以下选项 - 标题 - （输入文字的部分..） 播放列表的艺术家 - （包含所有艺术家帖子名称的下拉菜单） 没有要播放的曲目 - （键入数字的部分..）
我正在尝试在我的艺术家页面模板中显示此小部件，以便它在每个艺术家页面上显示该特定艺术家帖子的音乐。
我已将以下内容添加到我的single-artists.php页面模板 -
<?php the_widget( 'cs_music_player' ); ?>
这已经成功调用了小部件，因为我现在收到消息“找不到结果”＃39;在页面..我需要做的是能够在PHP中选择上面的选项..我很遗憾无法解决如何做到这一点..
这是cs_music_playlist_widget.php代码 -
<?php
class cs_music_player extends WP_Widget
{
function cs_music_player()
{
$widget_ops = array('classname' => 'cs_music_player', 'description' => 'Select artist to Play Your Playlist.' );

}
function form($instance)
{
$instance = wp_parse_args( (array) $instance, array( 'title' => '' ) );
$title = $instance['title'];
$get_post_slug = isset( $instance['get_post_slug'] ) ? esc_attr( $instance['get_post_slug'] ) : '';

答案 0 :(得分：0)
the_widget接受三个论点：
$widget：小部件名称，在您的情况下为cs_music_player $instance：小部件实例设置。它是您的窗口小部件选项所在的数组。您可以执行以下操作：array('title' => 'Your widget title', 'get_post_slug' => 'slug_of_your_artist', 'numtrack' => 10)
$args：用于显示窗口小部件的一系列选项。您可以发送一个空数组来使用默认值，或者只是忽略该参数。
最后，您的小部件调用将如下所示：
global $post;
the_widget(
'cs_music_player',
array(
'title' => 'Your widget title',
'get_post_slug' => $post->post_name,
'numtrack' => 10
)
);
