计算来自 taxonomy.php 页面的每周过去 7 天帖子

问题描述

在我的分类存档页面上，我显示了查询分类的术语和子术语。 我还想回应与每个子术语相关的帖子数量。下面的代码工作正常，但我只想计算最近/新的帖子，例如。在过去 7 天内发布。

是否可以通过任何方式过滤 $term->count 来实现此目的？

$taxonomy = get_query_var('taxonomy');

// get main terms
$terms = get_terms( $taxonomy,array( 'orderby'    => 'name' ) 
);

// display terms
foreach ( $terms as $term ) {
    echo '<h2 class="text-center">' . $term->name . '</h2>';

    // display term children as list
    $term_id = $term->term_id;
    $child_terms =  get_term_children( $term_id,$taxonomy );
    
    echo '<ul class="lesson-categories">';
    foreach ( $child_terms as $child_term ) {
        $term = get_term_by( 'id',$child_term,$taxonomy );            
        echo '<li>';
        echo $term->name;

        // SHOW POST COUNT
        echo $term->count;

        echo '</li>';       
    }
    echo '</ul>';
}

解决方法

我们可以创建一个自定义函数，查询当前的 taxonomy term 并指定一个 date_query after 属性。

/**
 * https://stackoverflow.com/a/66780352/3645650
 * `get_posts_tally_weekly( $post_type = 'post',$post_status = 'any',$taxonomy = 'category',$term = 'uncategorized' );`
 * @return Integer Return a weekly posts tally.
 * @param String $post_type (Optional) Post type to query. Default to 'post'.
 * @param String $post_status (Optional) Post status to query. Default to 'any'.
 * @param String $taxonomy (Optional) Taxonomy to query. Default to ''.
 * @param String $term (Optional) Term to query. Default to ''.
 */
function get_posts_tally_weekly( $post_type = 'post',$term = 'uncategorized' ) {
    $query = new WP_Query( [
        'post_type' => $post_type,'post_status' => $post_status,'orderby' => 'date','order' => 'DESC',$taxonomy => $term,'date_query' => [
            'after' => '1 week ago'
        ],] );
    return $query->found_posts;
    wp_reset_postdata();
};

在前端，我们可以调用我们的自定义函数 get_posts_tally_weekly()。我们可以指定 $post_type、$post_status、$taxonomy 和 $term。

从分类页面，检索每周帖子数：

<?= get_posts_tally_weekly( 'custom-post-type-slug','publish',get_queried_object()->taxonomy,get_queried_object()->slug ); ?>

基于答案的@amarinediary 解决方案。 带有 date_query 的新 WP_Query 成功了：

// SHOW POST COUNT
$post_args = array(
    'post_type' => 'guided_lessons','tax_query' => array(
        array(
            'taxonomy' => $taxonomy,'field'    => 'id','terms'    => $child_term,),// Checking for the date here
    'date_query' => array(
        array(
            'after' => '1 week ago',);
$post_query = new WP_Query( $post_args );
$new_posts = $post_query->found_posts;
echo $new_posts;
