我為 CPT 事件添加了兩個自定義欄位：日 (event_day) 和月 (event_month)（均為廣播型別）。現在我希望能夠通過 meta_key 日和月獲得帖子。
除了帶有 $meta_query 的部分外，短代碼有效。
海岸代碼應該如下所示： [tribe_custom_events_list_mm_wed cat="Rodrigo" num="6" day="Monday" month="October"]
Bellow是負責短代碼的代碼，添加在functions.php中
function tribe_custom_events_shortcode($atts, $content = null)
{
global $post;
extract(shortcode_atts(array(
'cat' => '',
'num' => '',
'order' => 'ASC',
'orderby' => 'post_date',
'taxonomy' => 'tribe_events_cat',
'field' => 'name',
'day' => '',
'month' => '',
), $atts));
$tax_query = array(
'taxonomy' => $taxonomy,
'field' => $field,
'terms' => $cat,
);
$day = $day;
$month = $month;
$meta_query = array(
array(
'key' => 'event_day',
'value' => '$day',
'compare' => '='
),
array(
'key' => 'event_month',
'value' => '$month',
'compare' => '='
),
);
$args = array(
'post_type' => 'tribe_events',
'posts_per_page' => $num,
'order' => $order,
'orderby' => $orderby,
'tax_query' => array($tax_query),
'meta_query' => array($meta_query),
);
$output = '';
$posts = get_posts($args);
foreach ($posts as $post) {
setup_postdata($post);
$output .= '<div >';
$output .= '<h4 ><a href="' . get_the_permalink() . '">' . get_the_title() . '</a></h4>';
$output .= '</div>';
}
echo '<pre>' , var_dump($meta_query) , '</pre>';
wp_reset_postdata();
return '<div>' . $output . '</br>' . '</div>';
}
add_shortcode('tribe_custom_events_list_mm_wed', 'tribe_custom_events_shortcode');
uj5u.com熱心網友回復：
這應該對你有用。您的代碼中有一些錯誤......在下面的評論中注明。
$tax_query = array(
'taxonomy' => $taxonomy,
'field' => $field,
'terms' => $cat,
);
/* This is unnecessary since $day already = $day
$day = $day;
$month = $month;
*/
$meta_query = array(
array(
'key' => 'event_day',
'value' => $day, // Don't put quotes around variables
'compare' => '='
),
array(
'key' => 'event_month',
'value' => $month,
'compare' => '='
),
);
$args = array(
'post_type' => 'tribe_events',
'posts_per_page' => $num,
'order' => $order,
'orderby' => $orderby,
'tax_query' => $tax_query, // This is already an array defined above
'meta_query' => $meta_query,
);
