PHPCMS V9跨站调用推荐位URL为空问题的解决办法

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：

/**
 * 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

/**
	 * 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。
