Emlog 文章内容功能三合一

忙里偷闲
先唠叨几句,
已经好久没更新了
手机弄Emlog后台模板,弄的我眼睛疲劳,
这次弄完就不打算弄后台模板了,
我自己,已经够用了,
不折腾了后台了,太累了,
就在这两天发布,大家请关注吧!
上次群里的人说要这个功能,现在我就发布了
好了言归正传!
我说的文章内容功能三合一就是
1.文章内容添加文章索引,我这里是调用H2的
2.文章内容有含有标签的添加链接
3.文章内容有外链的添加nofollow

关键代码添加到Module.php文件中

function article_index($content , $domain) {
global $CACHE;
$tag_cache = $CACHE->readCache('tags');
$matches = array();
$ul_li = '';
$r = "/
([^<]+)<\/h2>/im";
if(preg_match_all($r,$content,$matches)) {
foreach($matches[1] as $num => $title) {
$content = str_replace($matches[0][$num], '"title-'.$num.'">'.$title.'', $content);
$ul_li .= '
"#title-'.$num.'" title="'.$title.'">'.$title."
}
$content = "\n
[文章目录]
\n" . $ul_li . "

\n" . $content;

}

foreach($tag_cache as $value){

$tag_url = Url::tag($value['tagurl']);

$keyword = $value['tagname'];

$cleankeyword = stripslashes($keyword);

$url = "{$cleankeyword}";

$regEx = '\'(?!((<.*?)|($cleankeyword . ')(?!(([^<>]*?)>)|([^>]*?))\'s';

$content = preg_replace($regEx,$url,$content);

}

preg_match_all('/href="(.*?)"/', $log_content, $matches);

if ($matches) {

foreach ($matches[1] as $val) {

if (strpos($val, $domain) === false) {

$log_content = str_replace('href="' . $val . '"', 'href="' . $val . '" rel="external nofollow" ', $log_content);

}

preg_match_all('/src="(.*?)"/', $log_content, $matches);

if ($matches) {

foreach ($matches[1] as $val) {

if (strpos($val, $domain) === false) {

$log_content = str_replace('src="' . $val . '"', 'src="' . $val . '" rel="external nofollow" ', $log_content);

}

return $content;

}

添加Css样式

#article-index {
border: 1px dashed #dedfe1;
float: left;
margin: 0 20px 20px 0;
padding: 0 6px;
width: 280px;
line-height: 24px;
}
#article-index b {
border-bottom: 1px dashed #ddd;
display: block;
line-height: 30px;
padding: 0 4px;
}
#index-ul {
margin: 5px;
line-height: 1.8;
}
#index-ul li {
background: none repeat scroll 0 0 transparent;
list-style-type: decimal;
padding: 4px 10px;
border-left: 1px solid #e2e2e2;
border-bottom: 1px solid #e2e2e2;
}
#index-ul li {
list-style: circle outside none;
}

最后,打开echo_log.php文件

查找

echo $log_content; ?>

替换(当然你们自己改过,就不是找这个咯)

echo article_index($log_content);?>
