pbootcms小程序添加上一篇下一篇的方法

\apps\api\controller\CmsController.php 添加一个入口
public function precontentandnextcontent(){
$scode = request('scode'); // 支持多个分类逗号隔开
$id = request('id'); // 支持多个分类逗号隔开
$data = $this->model->getpreAndnextContent($scode,$id);
json(1,$data);
}
\apps\api\model\CmsModel.php 添加对应的方法
public function getpreAndnextContent($scode,$id){
$field = array(
'a.id',
'a.title',
'a.filename',
'a.ico',
'a.scode'
);
$next = parent::table('ay_content a')->field($field)
->where("a.id>$id")
->where("a.acode='" . get_lg() . "'")
->where("a.scode= '".$scode."' and a.status=1")
->where("a.date<'" . date('Y-m-d H:i:s') . "'")
->order('a.id ASC')
->find();
$pre = parent::table('ay_content a')->field($field)
->where("a.id<$id")
->where("a.scode='" . $scode . "'")
->where("a.acode='" . get_lg() . "'")
->where('a.status=1')
->where("a.date<'" . date('Y-m-d H:i:s') . "'")
->order('a.id desc')
->find();
$data = array($pre,$next);
return $data;
}
