php - Wordpress 中的“为 foreach() 提供的参数无效”

问题描述

我正在创建一个 WP 网站。在主页中，我收到一个错误：

警告：在第 108 行的 /home2/siilverp/public_html/wp-content/themes/mts_steadyincome/page-home.php 中为 foreach() 提供的参数无效

这是 page-home.php 的代码：

  <?php if(!empty($mts_options['mts_featured_posts']) && !empty($mts_options['mts_featured_post_cat'])) { ?>
                <div class="home_article">
                    <?php 
                    foreach ( $mts_options['mts_featured_post_cat'] as $cat_id ) {
                        $featured_query = new WP_Query( apply_filters( 'steadyincome_featured_posts_query', array(
                            'cat' => $cat_id,
                            'posts_per_page' => 1
                        ) ) );

现在，我发现我必须输入 var_dump。然后，出现这样的情况：

从那里开始，我不知道该怎么办。我对编程一无所知。

解决方案

它会引发警告，因为您的 ["mts_featured_post_cat"]=> string(1) 是字符串而不是数组。
