V9默認的，當你某欄目填寫了SEO信息之后，會繼承到下級未添加SEO信息的欄目和內容。非常的煩人。

修改步驟：

打開：根目錄/phpcms/libs/functions/global.func.php
找到 function seo（約1435行）

將原來的SEO函數替換為

function seo($siteid, $catid = '', $title = '', $description = '', $keyword = '') {

if (!empty($title))$title = strip_tags($title);

if (!empty($description)) $description = strip_tags($description);

if (!empty($keyword)) $keyword = str_replace(' ', ',', strip_tags($keyword));

$sites = getcache('sitelist', 'commons');

$site = $sites[$siteid];

$cat = array();

if (!empty($catid)) {

$siteids = getcache('category_content','commons');

$siteid = $siteids[$catid];

$categorys = getcache('category_content_'.$siteid,'commons');

$cat = $categorys[$catid];

$cat['setting'] = string2array($cat['setting']);

}

$seo['site_title'] =isset($site['site_title']) && !empty($site['site_title']) ? $site['site_title'] : $site['name'];

$seo['keyword'] = !empty($keyword) ? $keyword : '';

$seo['description'] = isset($description) && !empty($description) ? $description : (isset($cat['setting']['meta_description']) && !empty($cat['setting']['meta_description']) ? $cat['setting']['meta_description'] : (isset($site['description']) && !empty($site['description']) ? '' : ''));

$seo['title'] = (isset($title) && !empty($title) ? $title.' - ' : '').(isset($cat['setting']['meta_title']) && !empty($cat['setting']['meta_title']) ? $cat['setting']['meta_title'].' - ' : (isset($cat['catname']) && !empty($cat['catname']) ? $cat['catname'].' - ' : ''));

foreach ($seo as $k=>$v) {

$seo[$k] = str_replace(array("/n","/r"), '', $v);

}

return $seo;
