随机显示Banner

http://www.backlog.cn/index.php/forums/viewthread/17/

以前用js来更换Banner的背景以及主题，可是每次登陆的时候由于登陆页面是用js直接跳转上一页的，所以每次自动运行到首页的scripts脚本就过不去了，为此我苦恼了好久．
现在，问题终于解决了．直接用php程序来随机调用Banner,真是方便啊！
现在贡献给需要的同志吧：

首先，将下列代码转寸为php程序．

代码:

<?php
$folder = '这里放你需要调用Banner的文件夹，如果是与Randombanner.php同一个文件夹里就保持空白';

// Space seperated list of extensions, you probably won't have to change this.
$exts = 'jpg jpeg png gif';

$files = array(); $i = -1; // Initialize some variables
if ('' == $folder) $folder = './';
$handle = opendir($folder);
$exts = explode(' ', $exts);
while (false !== ($file = readdir($handle))) {
    foreach($exts as $ext) { // for each extension check the extension
        if (preg_match('/\.'.$ext.'$/i', $file, $test)) { // faster than ereg, case insensitive
            $files[] = $file; // it's good
            ++$i;
            }
        }
    }
closedir($handle); // We're not using it anymore
mt_srand((double)microtime()*1000000); // seed for PHP < 4.2
$rand = mt_rand(0, $i); // $i was incremented as we went along

header('Location: '.$folder.$files[$rand]); // Voila!
?> 

然后，用/xxx/xxx/xxx/randombanner.php来调用就可以了．

希望大家喜欢啊！

如何在首页调用论坛最新帖子?

http://www.backlog.cn/index.php/forums/viewthread/16/

这个问题比较简单,只用将下列代码放到适当的位置即可.

代码:

<table>

<tr>
<td>标题</td>
<td>作者</td>
<td>发表时间</td>
<td>贴数</td>
<td>浏览</td>
<td>最后回复</td>
</tr>

{exp:forum:topic_titles orderby="post_date" sort="asc" limit="10"}
<tr>
<td><a href="{thread_path=forums/viewthread}">{title}</a></td>
<td><a href="{profile_path=forums/member}">{author}</a></td>
<td>{topic_date format="%m/%d/%Y %h:%i %a"}</td>
<td>{post_total}</td>
<td>{views}</td>
<td>On: {last_post_date format="%m/%d/%Y %h:%i %a"}<br />
By: <a href="{last_author_profile_path=forums/member}">{last_author}</a></td>
</tr>
{/exp:forum:topic_titles}

</table> 

 

如何在首页显示画廊里的图片?

http://www.backlog.cn/index.php/forums/viewthread/15/

1:首先要建立一个新模版.比如:weblog/showrand
2.将如下的代码放入模版中:

代码:

{exp:gallery:entries gallery="yourgalleryname" 
orderby="random" columns="1" rows="1"}

<table class="tableBorder" cellpadding="6" cellspacing="1" border="0" width="130px" align=center>
<tr>
<th align="center">Random Image</th>
</tr>

{entries}

{row_start}<tr>{/row_start}

{row}

<td class="thumbs">
<a href="{id_path=gallery/image_med}" onclick="window.open(this.href, '_blank', 'width=700,height=500,location=no,menubar=no,resizable=yes,scrollbars=yes');
return false;" ><  img src="{thumb_url}"  class="border" width="{thumb_width}" height="{thumb_height}" border="0" title="{title}" alt="{title}"  >
<br />
{title}
</a>
</td>
</td>
{/row}

{row_blank}<td class="thumbs"> </td>{/row_blank}

{row_end}</tr>{/row_end}

{/entries}
</table>
{/exp:gallery:entries} 

3.最后,用{embed="weblog/showrand"}语句,或者IFRAME将它放到你所需要显示的地方.
