api接口自定义模板，sql作为条件查询

{php $db = \Phpcmf\Service::M()->db;}

{table table=1_form_zwjhfb status=1 order=inputtime}

{php $api[$key]['id']=$t['id'];}

{php $api[$key]['title']=$t['title'];}

{php $api[$key]['xyzw']=$t['xyzw'];}

{php $api[$key]['xyrs'] = $db->table('dr_1_form_zwjhxxb')->where('bsqzw_id',$t['id'])->count() ?: 0;}

{php $api[$key]['inputtime']=dr_date($t['inputtime'], 'Y-m-d H:i');}

{/table}


这个是自定义模板标签，这里报错了。通过一张表里字段作为条件去查询另一张表的数量
{php $api[$key]['xyrs'] = $db->table('dr_1_form_zwjhxxb')->where('bsqzw_id',$t['id'])->count() ?: 0;}
