WordPress：随机显示 4 个类别和 3 个最新帖子

Question

我正忙于建立一个随机显示 4 个类别的行，其中包含类别标题和其下的 3 个最新帖子。但是我不知道如何以随机顺序获取类别，因为 'orderby' 不工作...

有人可以帮我吗？

我使用的代码：

 <?php
    //for each category, show all posts
    $cat_args   = array(
        'orderby' => 'rand',
        'order' => 'ASC'
    );
    $limit      = 4;
    $counter    = 0;
    $categories = get_categories($cat_args);

    foreach ($categories as $category):
        if ($counter < $limit) {
            $args  = array(
                'showposts' => 3,
                'category__in' => array(
                $category->term_id
            ),
            'caller_get_posts' => 1
        );
        $posts = get_posts($args);
        if ($posts) {
            echo '<h3><a href="' . get_category_link($category->term_id) . '" title="' . sprintf(__("View all posts in %s"), $category->name) . '" ' . '>' . $category->name . '</a> </h3>';
            foreach ($posts as $post) {
                setup_postdata($post);
?>

<p><a href="<?php the_permalink(); ?>" rel="bookmark" title="Permanent Link to <?php the_title_attribute(); ?>"><?php the_title(); ?></a></p>

<?php
            } // foreach($posts
        } // if ($posts
    } // foreach($categories
?>

<?php
    $counter++;
    endforeach;
?>

Answer 1

您可以使用它来随机获取猫：

$categories = get_the_category($my_query->post->ID);
$catCount = count($categories);
//select a random category id
$id = rand(0,$catCount-1);
//cat id
$catId = $categories[$id]->term_id;

and replace to lines like

if(is_array($cat)) {
$categories = get_the_category($my_query->post->ID);
$catCount = count($categories);
//select a random category id
$id = rand(0,$catCount-1);
//cat id
$catId = $categories[$id]->term_id;
} else {
$catId = $cat;
}

删除下面的代码。这仅适用于帖子。

$cat_args   = array(
        'orderby' => 'rand',
        'order' => 'ASC'
    );

使用如下代码：

$categories = get_categories();
shuffle ($categories); // Just add shuffle and you will get random categories.
