Tạo một bài dính trên blog thử nghiệm của bạn và hãy xem tại trang chủ của trang web. Bạn sẽ thấy văn bản thêm vào các bài dính, và sau này nên được chuyển đến đầu của The Loop.

Perhaps you want to create two Loops based on different categories. Perhaps one Loop should have featured posts while the other has the default posts based on the page URL. For this example we re going to create two category Loops. To create the two category Loops you need to create two separate instances of the WP_Query class. Copy the following code snippet into one of your template files php query1 new WP_Query array cat get_cat_ID aciform if query1- have_posts h1 Aciform Posts h1 php while query1- have_posts query1- the_post h2 php the_title h2 php echo hr query2 new WP_Query array cat get_cat_ID Cat B if query2- have_posts h1 Cat B Posts h1 php while query2- .
