我们以Demo模块为例，新建App/Demo/Models/Content.php

<?php namespace Phpcmf\Model\Demo;

// 模块内容模型类

class Content extends \Phpcmf\Model\Content {

    
    
    // 格式化显示内容
    public function _call_show($data) {
    
    // 上一篇文章
$builder = \Phpcmf\Service::M()->db->table($this->mytable);
$builder->where('status', 9);
$builder->where('id<', $data['id'])->orderBy('id desc');
$data['prev_page'] = $builder->limit(1)->get()->getRowArray();

// 下一篇文章
$builder = \Phpcmf\Service::M()->db->table($this->mytable);
$builder->where('status', 9);
$builder->where('id>', $data['id'])->orderBy('id asc');
$data['next_page'] = $builder->limit(1)->get()->getRowArray();
    
        return $data;
    }
    
}
