emlog博客程序默認(rèn)是的總的瀏覽數(shù)排序,這段熱門日志的代碼在include/model/log_model.php文件中第342~355行,官方默認(rèn)的log_model.php文件,你自己修改過的,我也不知道在哪行.

其中第346行的mysql查詢語句,代碼如下:

$sql = "SELECT gid,title FROM " . DB_PREFIX . "blog WHERE hide='n' and type='blog' ORDER BY views DESC, comnum DESC LIMIT 0, $num";

從emlog_blog讀出不隱藏（hide='n'）和是日志的（type='blog'，這個(gè)去掉了頁面）日志，ORDER　BY　views DESC,comnum DESC LIMIT 0,$num這里$num設(shè)置顯示的條數(shù)比如5條，那么以views（瀏覽數(shù)）降序排列，如果瀏覽數(shù)相同的話以評(píng)論數(shù)定先后順序，取5條。

從上面代碼中可以看出,越早以前的文章的話閱讀數(shù)肯定是比較多,那么導(dǎo)致這個(gè)熱門日志排行上的文章幾乎是不變的,所以個(gè)人認(rèn)為有點(diǎn)不妥.

下面來改造代碼(屬于官方解釋的HACK程序,有一定的危險(xiǎn),操作前先備份數(shù)據(jù)).

1.熱門日志改成熱評(píng)日志（以評(píng)論數(shù)作為排行,評(píng)論數(shù)相同以瀏覽數(shù)定先后順序）,只要交換下views和comnum就可以了，修改后的代碼如下:

$sql = "SELECT gid,title FROM " . DB_PREFIX . "blog WHERE hide='n' and type='blog' ORDER BY comnum DESC,views DESC LIMIT 0, $num";

PS:適合平常日志評(píng)論比較多的博客,如果平常評(píng)論比較少的話,變化也是不大的.

2.熱門日志改成本月熱門日志,規(guī)定取日志發(fā)表的時(shí)間范圍后以瀏覽數(shù)降序,相同瀏覽數(shù)的以評(píng)論數(shù)的降序排列,這里要分2種情況:一種是本月的,還有一種是最近30天的.

那么先來說說本月的,得到本月起點(diǎn)的時(shí)間戳,代碼如下:

$t = mktime(0,0,0,date("m",time()),1,date("Y",time())); //本月起點(diǎn)的時(shí)間戳 $sql = "SELECT gid,title FROM " . DB_PREFIX . "blog WHERE hide='n' and type='blog' and date>$t ORDER BY views DESC, comnum DESC LIMIT 0, $num";

修改后的完整代碼:

function getHotLog($num) {

    $t   =   mktime(0,0,0,date("m",time()),1,date("Y",time()));

    $sql = "SELECT gid,title FROM " . DB_PREFIX . "blog WHERE hide='n' and type='blog' and date>$t ORDER BY views DESC, comnum DESC LIMIT 0, $num";//開源軟件:Vevb.com

    $res = $this->db->query($sql);

    $logs = array();

    while ($row = $this->db->fetch_array($res)) {

        $row['gid'] = intval($row['gid']);

        $row['title'] = htmlspecialchars($row['title']);

        $logs[] = $row;

        }

    return $logs;

    }

那么最近30天也就簡(jiǎn)單了,只要把$t的那個(gè)改改就可以了,代碼如下:

$t = time() - 3600 * 24 * 30;//以當(dāng)前訪問的時(shí)間戳最近30天

3.全部文章按當(dāng)月的瀏覽數(shù)降序排列,相同瀏覽數(shù)的按評(píng)論數(shù)降序排列,這里對(duì)數(shù)據(jù)庫就需要添加2個(gè)字段,執(zhí)行下面查詢語句,數(shù)據(jù)庫前綴默認(rèn)為emlog.

添加最后瀏覽的時(shí)間的字段:

ALTER TABLE emlog_blog ADD lastview bigint(20) NOT NULL default '0'

添加本月瀏覽數(shù)的字段:

ALTER TABLE emlog_blog ADD monviews mediumint(8) unsigned NOT NULL default '0'

數(shù)據(jù)庫修改完畢,下面是log_model.php程序的修改。第289~296行增加閱讀次數(shù),這里這個(gè)執(zhí)行總瀏覽數(shù)和當(dāng)月瀏覽數(shù)每次瀏覽+1,還有下月清0,完整代碼如下:

//[2013-05-30]更新代碼：合并update語句

/**

  * 增加閱讀次數(shù),修改最后閱讀時(shí)間，增加本月閱讀次數(shù)

  *

  * @param int $blogId

  */

function updateViewCount($blogId) {

  $this->db->query("UPDATE " . DB_PREFIX . "blog SET views=views+1 WHERE gid=$blogId");

  $res=$this->db->query("SELECT date,lastview FROM " . DB_PREFIX . "blog WHERE gid=$blogId");

  $row = $this->db->fetch_array($res);

        if(date("m",time())!=date("m",$row['lastview']) && date("m",time())!=date("m",$row['date']))

  {$this->db->query("UPDATE " . DB_PREFIX . "blog SET monviews=0,lastview=".time());}

  $this->db->query("UPDATE " . DB_PREFIX . "blog SET monviews=monviews+1,lastview=".time()." WHERE gid=$blogId");

}

//[2012-11-30]代碼：

/**

* 增加閱讀次數(shù),修改最后閱讀時(shí)間，增加本月閱讀次數(shù)

*

* @param int $blogId

*/

function updateViewCount($blogId) {

    $this->db->query("UPDATE " . DB_PREFIX . "blog SET views=views+1 WHERE gid=$blogId");//總瀏覽數(shù)每次瀏覽+1

    $res=$this->db->query("SELECT date,lastview FROM " . DB_PREFIX . "blog WHERE gid=$blogId");//查詢?nèi)罩景l(fā)表時(shí)間和最后瀏覽時(shí)間

    $row = $this->db->fetch_array($res);

    if(date("m",time())!=date("m",$row['lastview']) && date("m",time())!=date("m",$row['date']))//判斷當(dāng)前時(shí)間的月份和最后瀏覽時(shí)間的月份，以及判斷最后瀏覽時(shí)間的月份和發(fā)表時(shí)間的月份是否一樣。

    {$this->db->query("UPDATE " . DB_PREFIX . "blog SET monviews=0");//執(zhí)行當(dāng)月瀏覽數(shù)清0

    $this->db->query("UPDATE " . DB_PREFIX . "blog SET lastview=".time());//設(shè)置最后瀏覽時(shí)間到當(dāng)前時(shí)間

}

    $this->db->query("UPDATE " . DB_PREFIX . "blog SET monviews=monviews+1 WHERE gid=$blogId");//執(zhí)行當(dāng)月瀏覽數(shù)+1

    $this->db->query("UPDATE " . DB_PREFIX . "blog SET lastview=".time()." WHERE gid=$blogId");//更新最后瀏覽時(shí)間到當(dāng)前時(shí)間

    }
