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:

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:

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。
