我已经继承了WordPress Twig网站,并且正在尝试修改页面中使用的现有短代码,以输出博客页面和单个类别帖子页面的博客帖子。
这些短代码显而易见:
[blog_list category_exclude="in-the-news"]
用于" Blog"页面,不包括category_exclude
的新闻类别。
[blog_list category="in-the-news"]
用于具有category
的该类别的新闻帖子页面。
我添加了另一个类别,即视频,这适用于视频帖子类别页面:
[blog_list category="videos"]
但我需要做的是使用category_exclude
在博客页面上排除多个类别,如下所示:
[blog_list category_exclude="in-the-news videos"]
这不起作用,所以我知道我需要为下面的if循环修改query_posts,以确定要排除的类别。如何使category_exclude
参数使用多个参数?
这是完整的短代码功能:
add_shortcode('blog_list', 'blog_get_list');
function blog_get_list($params) {
global $paged;
$blog_posts = [];
if (!isset($paged) || !$paged){
$paged = 1;
}
$page_size = 20;
$context = Timber::get_context();
if (!empty($params['page_size'])) {
$page_size = $params['page_size'];
}
$args = array(
'post_type' => 'post',
'posts_per_page' => $page_size,
'paged' => $paged,
'orderby' => 'date',
'order' => 'DESC',
'post_status' => 'publish'
);
if (!empty($params['category'])) {
$args['tax_query'] = array(
array(
'taxonomy' => 'category',
'terms' => explode(',', $params['category']),
'field' => 'slug',
'operator' => 'IN',
),
);
}
if (!empty($params['category_exclude'])) { // Exclude categories
$args['tax_query'] = array(
array(
'taxonomy' => 'category',
'terms' => explode(',', $params['category_exclude']),
'field' => 'slug',
'operator' => 'NOT IN',
),
);
}
query_posts($args);
$posts = Timber::get_posts();
foreach ($posts as $p) {
$blog_posts[] = acco_blog_get_single($p);
}
$context['blog_posts'] = $blog_posts;
$context['pagination'] = Timber::get_pagination();
return Timber::compile('blog/index.twig', $context);
}
function acco_blog_get_single($post) {
$blog_post = [
'id' => $post->ID,
'link' => $post->link,
'title' => $post->title(),
'author_name' => $post->author_name,
'date' => $post->post_date,
'summary' => $post->get_field('summary'),
'body' => $post->get_field('body')
];
$feature_image = $post->get_image('feature_image');
if ($feature_image->ID){
$blog_post['feature_image'] = $feature_image;
}
return $blog_post;
}
答案 0 :(得分:2)
根据上面的代码,您只需指定要排除的逗号分隔的类别列表:
[blog_list category_exclude="in-the-news videos"]
应改为
[blog_list category_exclude="in-the-news,videos"]
这是因为在上面的代码中,它将category_exclude字符串分解为一个数组,在找到任何逗号的地方进行拆分:
if (!empty($params['category_exclude'])) { // Exclude categories
$args['tax_query'] = array(
array(
'taxonomy' => 'category',
'terms' => explode(',', $params['category_exclude']), // "cat1,cat2" would become ["cat1","cat2"] here
'field' => 'slug',
'operator' => 'NOT IN',
),
);
}
