php - WordPress按类别自定义帖子分页
问题描述
我使用“CPT（自定义帖子类型）ajax 分页”wordpress 插件在我的任何页面中显示分页。它完美地工作，显示我在页面上放置分页短代码的所有帖子。我遇到了一些麻烦，我创建了一个页面来在页面中显示分类明智的帖子。'CPT(custom post type) ajax pagination' 插件有一个选项，但它不工作。[cptapagination custom_post_type='yourposttype' cptataxname='taxonamyname' cptacatname='categoryname' post_limit='5']. 我正在尝试自定义代码，但它不起作用。请帮我解决这个问题。请检查以下代码
function cptapagination_callback() {
global $wpdb, $post;
$cptaNumber = absint($_POST['number']);
$cptaLimit = absint($_POST['limit']);
$cptaType = sanitize_text_field($_POST['post']);

$cptataxname = sanitize_text_field($_POST['category']);
