分页查询
DB分页查询方法：
$where = array();
$where[] = ['delete_time', '=', 0];
$rows = empty($param['limit']) ? get_config('app.page_size') : $param['limit'];
$list = Db::name('Customer')
->field('id,name,address')
->order('id asc')->where($where)->paginate($rows, false)
->each(function($item, $key){
$contact = Db::name('CustomerContact')->where(['cid'=>$item['id'],'is_default'=>1])->find();
if(!empty($contact)){
$item['contact_name'] = $contact['name'];
$item['contact_mobile'] = $contact['mobile'];
}
else{
$item['contact_name'] = '';
$item['contact_mobile'] = '';
}
return $item;
});
Model分页查询方法：
$where = [];
$where[] = ['delete_time', '=', 0];
$rows = empty($param['limit']) ? get_config('app.page_size') : $param['limit'];
$list = ReceiptList::order('create_time desc')
->paginate($rows, false, ['query' => $param])
->each(function ($item, $key) {
$item->order = Db::name('Sold')->where(['id' => $item->sold_id])->find('code');
$item->customer = Db::name('Customer')->where(['id' => $item->customer_id])->find('name');
});
