我在 wordpress 中有一个 ajax 滑块，它正在生成 Invalid Argument 错误，这似乎源于

<li class="portfolio-col-<?php echo $portfolio_column_count++; ?>" data-portfolio="portfolio-<?php echo $post->ID; ?>" data-id="id-<?php echo $idCount++; ?>" data-type="<?php foreach ($portfolio_cats as $taxonomy) { echo 'filter-' . $taxonomy->slug . ' '; } ?>">

这是第 62 行，形成下面的代码。我无法弄清楚，因此不胜感激。

<div class="ajax-portfolio-block-wrap">
    <?php if (have_posts()) : ?>
        <?php while (have_posts()) : the_post(); ?>
                <?php $page_title=get_the_title(); ?>

                <div class="ajax-gallery-navigation">
                    <div id="ajax-portfolio-loading"></div>
                    <a class="ajax-navigation-arrow ajax-prev" href="#">Prev</a>
                    <a class="ajax-navigation-arrow ajax-next" href="#">Next</a>
                </div>
                <div class="ajax-portfolio-window">
                    <div id="ajax-portfolio-wrap"></div>
                </div>

        <?php endwhile; else: ?>
    <?php endif; ?>

    $columns=4;
    ?>

似乎该函数get_categories在下一行中没有返回任何有效的数组。

$categories=  get_categories('child_of='.$portfolio_cat_ID.'&orderby=slug&taxonomy=types&title_li=');

因此，foreach不能迭代$categories
