php - 类别和标签的 Wordpress 分页问题

Question

我有一个 WordPress 页面来列出带有类别和标签过滤器的帖子。我的分页有问题，即当我们在第二页并单击任何类别时，分页保持不变。如果我更改类别或关键字，则始终 1 应该处于活动状态。而且，如果我们在第一页并选择任何类别并转到未选择类别的第二页。我对WordPress不太熟悉。有没有办法解决这个问题？谢谢你

    $currentPage = get_query_var('paged');
// General arguments
if (isset($_POST['category'])) {
$selectedCategories = $_POST['category']; // outputs the array with selected category;
$currentPage = 0;
}
if (isset($_POST['tags'])) {
$selectedTags = $_POST['tags'];// outputs the array with selected tags
$currentPage = 0; // set page is 0
}
$posts = new WP_Query(array(
'category__and' => $selectedCategories,
'tag__in' => $selectedTags,
'post_type' => 'post', // Default or custom post type
'posts_per_page' => 5, // Max number of posts per page
'paged' => $currentPage
));
$categoryTitle =  !empty(get_field( "category_title", $post->ID )) ? get_field( "category_title", $post->ID ) : 'Kategorien';
$tagTitle = !empty(get_field( "tag_title", $post->ID )) ? get_field( "tag_title", $post->ID ) : 'Schlagworte';
?>
<?php
//banner image
if (has_post_thumbnail($post->ID)) : ?>
<?php $image = wp_get_attachment_image_src(get_post_thumbnail_id($post->ID), 'single-post-thumbnail'); ?>
<div id="banner-img" style="background-image: url('<?php echo $image[0]; ?>')">
