WordPress查询文章分类
定义查询函数
function get_post_category_id($post_ID)
{
global $wpdb;
$sql="SELECT `term_taxonomy_id` FROM $wpdb->term_relationships WHERE `object_id`='".$post_ID."';";
$cat_id=$wpdb->get_results($sql);
foreach($cat_id as $catId)
{
$output=$catId->term_taxonomy_id;
}
return($output);
}
在需要的地方调用
<?php
foreach((get_the_category()) as $category)
{
echo $category->cat_name . ' ';
}
?>
