PHPCMS V9跨站调用推荐位出现URL连接为空问题的解决方法

如题，如果你在使用PHPCMS V9的时候需要在不同的站点之间调用推荐位可能会出现链接的URL为空的情况，具体解决办法如下，该办法适合20130522 之前版本
一、在自定义函数中加入下面的函数：

复制代码代码如下:
/**
* 获取内容地址
* @param $catid 栏目ID
* @param $id 文章ID
* @param $allurl 是否以绝对路径返回
*/
function go_dusion($catid,$id, $allurl = 0) {
static $category;
if(empty($category)) {
$siteids = getcache('category_content','commons');
$siteid = $siteids[$catid];
$category = getcache('category_content_'.$siteid,'commons');
}
if($siteid == '' || empty($siteid)) {
$siteids = getcache('category_content','commons');
$siteid = $siteids[$catid];
$category = getcache('category_content_'.$siteid,'commons');
}
$id = intval($id);
if(!$id || !isset($category[$catid])) return '';
$modelid = $category[$catid]['modelid'];
if(!$modelid) return '';
$db = pc_base::load_model('content_model');
$db->set_model($modelid);
$r = $db->get_one(array('id'=>$id), '`url`');
if (!empty($allurl)) {
if (strpos($r['url'], '://')===false) {
if (strpos($category[$catid]['url'], '://') === FALSE) {
$site = siteinfo($category[$catid]['siteid']);
$r['url'] = substr($site['domain'], 0, -1).$r['url'];
} else {
$r['url'] = $category[$catid]['url'].$r['url'];
}
}
}

return $r['url'];
}

第二：在content/classes/content_tag.class.php 的 public function position($data)函数中

复制代码代码如下:
/**
* 推荐位
* @param $data
*/
public function position($data) {
$sql = '';
$array = array();
$posid = intval($data['posid']);
$order = $data['order'];
$thumb = (empty($data['thumb']) || intval($data['thumb']) == 0) ? 0 : 1;
//Du修改
if(isset($data['siteid']) && is_numeric($data['siteid'])){
$siteid = $data['siteid'];
}else{
$siteid = $GLOBALS['siteid'] ? $GLOBALS['siteid'] : 1;
}
$catid = (empty($data['catid']) || $data['catid'] == 0) ? '' : intval($data['catid']);
if($catid) {
$siteids = getcache('category_content','commons');
if(!$siteids[$catid]) return false;
$siteid = $siteids[$catid];
$this->category = getcache('category_content_'.$siteid,'commons');
}
if($catid && $this->category[$catid]['child']) {
$catids_str = $this->category[$catid]['arrchildid'];
$pos = strpos($catids_str,',')+1;
$catids_str = substr($catids_str, $pos);
$sql = "`catid` IN ($catids_str) AND ";
} elseif($catid && !$this->category[$catid]['child']) {
$sql = "`catid` = '$catid' AND ";
}
if($thumb) $sql .= "`thumb` = '1' AND ";
if(isset($data['where'])) $sql .= $data['where'].' AND ';
if(isset($data['expiration']) && $data['expiration']==1) $sql .= '(`expiration` >= \''.SYS_TIME.'\' OR `expiration` = \'0\' ) AND ';
$sql .= "`posid` = '$posid' AND `siteid` = '".$siteid."'";
$pos_arr = $this->position->select($sql, '*', $data['limit'],$order);
if(!empty($pos_arr)) {
foreach ($pos_arr as $info) {
$key = $info['catid'].'-'.$info['id'];
$array[$key] = string2array($info['data']);
$array[$key]['url'] = go_dusion($info['catid'],$info['id']);
$array[$key]['id'] = $info['id'];
$array[$key]['catid'] = $info['catid'];
$array[$key]['listorder'] = $info['listorder'];
}
}
return $array;
}

即可，注意看两处红色区域，11-16行是为了获取siteID 可以根据情况不修改也可以
42行，即将原来 的go 改为 go_dusion其它不变即可。
