这是我试图通过 wp_query 实现的模式。这将适用于相同的帖子类型。是否可以使用 wp_query 这样做？

谢谢！

        <div>

          <div>1st post from featured</div>

          <div>1st post not from featured</div>

          <div>2nd post from featured</div>

          <div>3rd post from featured</div>

          <div>2nd post not from featured</div>

          <div>3rd post not from featured</div>

          ..and then the same pattern start again with the rest of the posts

          <div>4th post from featured</div>

          <div>4th post not from featured</div>

          <div>5th post from featured</div>

          <div>6th post from featured</div>

          <div>5th post not from featured</div>

          <div>6th post not from featured</div>

          ..until there's no more post
        </div>

它变得稍微复杂一些。我们需要两个 WP_Query 对象、一些计算和一个 for 循环。

为了让 PHP 知道正确的格式，我们可以使用一个简单的格式数组。在以下示例中，我将使用类别来确定两个 WP_Query 构建。

首先，我们构建基础变量：

<?php 

    // Build format
    // 0 means not featured - 1 means featured.
    $format = array(1, 0, 1, 1, 0, 0);

    // Retrieve normal posts EXCLUDING category with ID 11 (Featured)
    $normal_posts = new WP_Query(array(
        'post_type'      => 'post',
        'posts_per_page' => 999,
        'cat'            => '-11'
    ));

    // Retrieve featured posts ONLY INCLUDING category with ID 11 (Featured)
    $featured_posts = new WP_Query(array(
        'post_type'      => 'post',
        'posts_per_page' => 999,
        'cat'            => 11
    ));

    // Calculate total amount of posts
    // from our two WP_Query results
    $posts_total = $normal_posts->post_count + $featured_posts;

    // Setup current post index
    $post_index = 0;

接下来，我们开始“循环”或迭代：

    // Iterate every post from two queries
    for($i = 0; $i < $posts_total; $i++){

我们在其中计算当前格式索引：

        // Calculate which type of post to display based on post index
        // We use modulo to get the right $format index
        $post_format_index = $post_index % count($format);
        $current_format    = $format[$post_format_index];

最后，显示正确的帖子类型：

        // Display to frontend based on format
        switch ($current_format) {
            case 1:
                // Featured
                $featured_posts->the_post();

                the_title();

                // Your content

                print '<br>';
                break;

            default:
                // Not Featured
                $normal_posts->the_post();

                the_title();

                // Your content

                print '<br>';
                break;
        }

        $post_index++;
    }

?>

就是这样。您可以通过添加另一个 WP_Query 和格式来更进一步。

$format = array(1, 0, 1, 1, 2, 2);
