我创建了一个名为knw\\u shr\\u docs的自定义帖子。我正在尝试创建一个短代码，该代码应根据类别显示帖子互动程序，即：[知识共享帖子/u per\\u page=\'5\'文档/u cat=\'docs\']类别应由我添加。我尝试的代码：-
function func_knowledge_sharing_docs(){
$a = shortcode_atts( array(
\'doc_cat\' => \'\'
), $atts );
$output = \'\';
$post_cat = esc_attr($a[\'doc_cat\']);
$args = array(
\'category\' => $post_cat,
\'post_type\' => \'knowledgeSharingDocs\',
\'order\' => \'DESC\'
);
$query = new WP_Query( $args );
$pages = $query->posts;
$output .= \'<ul>\';
foreach($pages as $page) {
$page_title = $page->post_title;
$page_url = get_page_link( $page->ID );
$output .= \'<li><a href="\'.$page_url.\'">\' .$page_title. \'</a></li>\';
}
$output .= \'</ul>\';
wp_reset_postdata();
return $output;
}
add_shortcode( \'knowledge_sharing\', \'func_knowledge_sharing_docs\' );
请任何人告诉我哪里错了。提前谢谢你。

请尝试以下代码。我想它可以帮助你。
add_shortcode( \'knowledge_sharing\', \'cat_post\' );
function cat_post($atts){
// attributes for shortcode
if (isset($atts[\'cat\'])) {$cats = $atts[\'cat\'];} else {return;}
if (isset($atts[\'posts_per_page\'])) {$posts_per_page = $atts[\'posts_per_page\'];} else {$posts_per_page = -1;}
// get the category posts
$category = get_category_by_slug($cat);
if (!is_object($category)) {return;}
$args = array(
\'cat\' => $category->term_id,
\'posts_per_page\' => $posts_per_page,
\'post_type\' => \'knowledgeSharingDocs\',
\'order\' => \'DESC\'
);
$posts = get_posts($args);
// create the list output
if (count($posts) > 0) {
foreach ($posts as $post) {
$link = get_permalink($post->ID);
$title = $post->post_title;
$image = get_the_post_thumbnail($post->ID, \'thumbnail\');
$output .= \'<div id="postrow-\'.$post->ID.\'" class="postrow">\';
$output .= \'<a class="postlink" href="\'.$link.\'">\'.$image;
$output .= \'<h5 class="posttitle">\'.$title.\'</h5></a></div>\';
}
return $output;
}
短代码：
[knowledge_sharing cat="pant" posts_per_page="5"]
