按分类和分类下级显示帖子

这是对Display Post by taxonomy and taxonomy child if exist

我需要显示住宿列表，首先按住宿类型，然后按地区。我有一个帖子类型，叫做accomodation, 分类法Country, 分类法accomodation-type, 分类法Region

我在国家/地区页面中，通过以下方式检索国家/地区的价值

$taxonomy = \'country\';
$terms=get_the_terms($post->ID,$taxonomy);

if($terms) {
    foreach( $terms as $termcountry ) {

所以我成功地$termcountry->name; 作为当前国家的价值。

接下来，我需要根据该国家/地区查询住宿，并按住宿类型和该类型中的地区进行过滤。应该是这样的

Acc类型1，区域1，Acco 1，Acco 2，Acc类型2，等等

$taxonomy2 = \'accomodation-type\';
$termsacc = get_terms("accomodation-type",array(\'orderby\' => \'slug\', \'order\' => \'ASC\'));
       //Loop through Acc-Type
        foreach ($termsacc as $termaccomodation) {
            //Loop through Region in this type
            $taxonomyregion = \'region\';
            $termsreg = get_terms("region",array(\'orderby\' => \'slug\', \'order\' => \'ASC\'));
             foreach ($termsreg as $termregion) {
            $args = array(
                \'post_type\' => \'accomodation\',
                \'country\' => $termcountry->name,
                \'tax_query\' => array(
                    \'relation\' => \'AND\',
                    array(
                        \'taxonomy\' => \'accomodation-type\',
                        \'field\' => \'slug\',
                        \'terms\' => array($termaccomodation->name),
                    ),
                    array(
                        \'taxonomy\' => \'region\',
                        \'field\' => \'slug\',
                        \'terms\' => array($termregion->name),
                    )
                )
            );


            $query = new WP_Query($arg); 
             //Do the loop

但这并没有做到。。。。这件事让我挠头，我会提前感谢您的帮助/解决方案THX

// Pseudo-code to explain the idea $prev_post_accomodation_type = $accomodations[0]->accomodation_type; $prev_post_region = $accomodations[0]->region; echo \'<ul>\'; echo \'<li>\' . $prev_post_accomodation_type . \'<ul>\'; echo \'<li>\' . $prev_post_region . \'<ul>\'; foreach ( $accomodations as $accomodation ) { $cur_post_accomodation_type = $accomodation->accomodation_type; $cur_post_region = $accomodation->region; if ( $prev_post_accomodation_type != $cur_post_accomodation_type ) { echo \'</ul></li>\'; // Close previous region list echo \'</ul></li>\'; // Close previous accomodation type list echo \'<li>\' . $cur_post_accomodation_type . \'<ul>\'; echo \'<li>\' . $cur_post_region . \'<ul>\'; } elseif ( $prev_post_region != $cur_post_region ) { echo \'</ul></li>\'; // Close previous region list echo \'<li>\' . $cur_post_region . \'<ul>\'; } echo \'<li>\' . $accomodation->post_title . \'</li>\'; } echo \'</ul></li>\'; // Close previous region list echo \'</ul></li>\'; // Close previous accomodation type list echo \'</ul>\';

如何按需激活jQuery/脚本？

我试图使用jQuery显示Wordpress页面的评论部分，但不要求jQuery出现在所有允许评论的页面上。基本上，我需要以下内容：“视图中”jQuery插件的通用javascript实现(http://remysharp.com/2009/01/26/element-in-view-event-plugin/)当包含注释的div出现时，激活jQuery（核心）的一种方法这将加载jQuery，而jQuery又将加载页面的注释部分，但只有当该部分在浏览器视口中可见时才会加载。问题似乎是我真的无法使用“wp\
