Get current index position in loop in WordPress 获取当前元素的系列，只需要 $wp_query->current_post while (have_posts()) : the_post(); // Some basic wordpress template tags the_title(); the_content(); // Echo the current index position of the loop (0,1,2,3..etc) echo $wp_query->current_post; endwhile; 或者还有种原始的方法： $key = “”; while (have_posts()) : the_post(); // Some basic wordpress template tags the_title(); the_content(); echo $key; $key++ endwhile;
