//重新组织信息

if ($datas){

$areaModel = D('Area');

$areas = "";

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

if ($v['area_id_1']){$areas = $v['area_id_1'];}

if ($v['area_id_2']){$areas .= ",".$v['area_id_2'];}

if ($v['area_id_3']){$areas .= ",".$v['area_id_3'];}

if ($v['area_id_4']){$areas .= ",".$v['area_id_4'];}

if ($v['area_id_5']){$areas .= ",".$v['area_id_5'];}

$area_names_arr = array();

$area_names = "";

if ($areas){

$areas_datas = $areaModel->where("id in ($areas)")->field("name")->select();//$areas

foreach ($areas_datas as $kk=>$vv){

$area_names_arr[] = $vv['name'];

}

$area_names = implode("，",$area_names_arr);

}

$datas[$k]['area_names'] = $area_names;

}

先把各级地区名准备好，然后放到一个数组作为数组元素，最后用implode将数组元素拆成逗号分隔的字符串显示。
