\n\tSau khi \u0111ã có 2 hàm trên thì vi\u1ec7c còn l\u1ea1i là chúng ta g\u1ecdi 2 hàm \u0111ó \u0111\u1ec3 s\u1eed d\u1ee5ng thôi.
\n\tTr\u01b0\u1edbc tiên, \u0111\u1ec3 có \u0111\u01b0\u1ee3c l\u01b0\u1ee3t view thì b\u1ea1n c\u1ea7n \u0111\u1ec3 function setPostViews()<\/strong> trong file single.php<\/strong> và nó ph\u1ea3i n\u1eb1m trong vòng l\u1eadp while.<\/p>\n
