Question

我有以下功能，我需要更新 $ how ，以便按 site_views DESC 对视频进行排序我尝试了很多次，但显示相同的输出或我得到空输出。谢谢提前。

function list_videos($how = 'added', $limit = '15') { // newest, top views, etc etc etc
    $query = mysql_query("SELECT * FROM pm_videos ORDER BY $how DESC LIMIT $limit");
    $result = '';
    while ($row = mysql_fetch_array($query)) {

        $results .= "
                <div class=\"item\">
                <a href=\"" . makevideolink($row['uniq_id'], $row['artist'], $row['video_title']) . "\"><img src=\"" . show_thumb($row['uniq_id']) . "\" alt=\"" . $row['video_title'] . "\" class=\"imag\" width=\"107\" height=\"72\" /></a>
                <a href=\"" . makevideolink($row['uniq_id'], $row['artist'], $row['video_title']) . "\" class=\"song_name\">
                <span class=\"artist_name\">" . fewchars($row['artist'] . " - " . $row['video_title'], 30) . "</span>
                </a>
                <span class=\"item_views\">" . pm_number_format($row['site_views']) . " views</span>
                </div>";
    }
    return $results;
}

此处推荐精选视频，但与其他代码（加载播放器）分开显示

function make_voth() {

    global $config;

    $video_id = '';

    $sql = "SELECT uniq_id 
            FROM pm_videos 
            WHERE featured = '1' 
            ORDER BY rand() 
            LIMIT 1";
    $result =  @mysql_query($sql);

    if (@mysql_num_rows($result) == 0)
    {
        $sql = "SELECT uniq_id 
                FROM pm_videos,
                ORDER BY rand() 
                LIMIT 1";

        $result = @mysql_query($sql);
        $row    = @mysql_fetch_assoc($result);
        $video_id = $row['uniq_id'];
        mysql_free_result($result);
    }
    else
    {
        $row = mysql_fetch_assoc($result);
        mysql_free_result($result);

        $video_id = $row['uniq_id'];
    }

    return $video_id;
}
function show_more_featured($mvotd = '', $limit = 3) {
    //  todo
}
function show_voth_title() {    
    //  @deprecated
}

Answer 1

您目前有一个默认显示按added排序的15行的函数。您可以通过以下两种方式之一进行更改：

更改功能本身。这将使DEFAULT值为site_views：

function list_videos($how = 'site_views', $limit = '15') { // newest, top views, etc etc etc

现在，如果您致电list_videos()，您将获得按网站视图desc。

排序的15个结果

OR

您可以更改在某个地方调用该函数的方式：

list_videos('site_views', 25);

这将按site_views排序，最多显示25个。

list_videos('video_title', 25);

另一个例子，按名称DESC排序可能并不好，但你明白了......

Answer 2

$featured = list_featured_videos('SELECT * FROM pm_videos  WHERE featured="1" ORDER BY site_views DESC LIMIT 10');

DESC的订单不适用于自定义变量$ how
