Question

如何解决此问题？我正在尝试在'category_name' => $category->slug的WP_Query中传递一个变量，但未在输出中显示任何帖子。当我从代码中删除'category_name' => $category->slug,行时，然后显示帖子，但需要按类别显示帖子。

<?php
function mytheme_schedule_shortcode($atts, $content = null){
    extract( shortcode_atts( array(
        'style'         => 1
    ), $atts) );
    $domain = 'mytheme-toolkit';
    $mytheme_schedule_categories = get_terms('schedule_cat');

    $mytheme_schedule_markup ='
        <section class="schedule-area bg-image ptb-120">
            <div class="container">
                <div class="row">
                    <div class="col-lg-12">
                        <div class="tab">
                            <ul class="tabs">';
                            if (!empty($mytheme_schedule_categories) && ! is_wp_error($mytheme_schedule_categories)) {
                                foreach($mytheme_schedule_categories as $category){
                                $mytheme_schedule_markup .='
                                <li>
                                    <a href="#">'.esc_html__($category->name).'
                                        <span>'.esc_html__($category->slug).'</span>
                                    </a>

您似乎在对帖子类型使用自定义分类法，在这种情况下，代码应类似于以下内容：

$args = array(
  'post_type' => 'schedule',
  'posts_per_page' => -1,
  'tax_query' => array(
    array(
        'taxonomy' => 'schedule_cat',
        'field'    => 'slug',
        'terms'    => $category->slug,
    ),
  ),
);
$schedule_array = new WP_Query( $args );

这应该可以为您解决问题。祝你好运！
