如何在codeigniter中将值数组动态发送到查询

模型中的代码是 公共函数get\u report6\u 8（$type，$filter\u id=NULL）{ $values=数组（$filter\u id）

控制器中的代码是 $data['report8']=$this->lead\u report\u model->get\u report6\u 8（$type，$this->input->post（'filter'）

视图中的代码是

总计：$Total]？$report8->总计：0；？>

如果我像这样运行查询

select sum(total) total

from (

    select value_of_sale total
    from lead
    left join natbuild_rep
    on natbuild_rep.mobile = lead.mobile
    left join natbuild_store
    on natbuild_store.id = natbuild_rep.store_id
    left join natbuild_principal
    on natbuild_principal.store_group = ifnull(natbuild_store.store_group2, natbuild_store.store_group)
where (status = 1 OR status = 2)
    and value_of_sale is not null
    and natbuild_principal.id in (18, 30, 31, 35, 33, 25, 23, 15, 8, 6, 5, 29, 7, 3, 2, 1, 24, 27, 22, 21, 20, 26, 36)
group by lead.id ) temp

结果是正确的。请帮助我如何将值数组发送到$select。当我从包含所有其他值的下拉列表中选择“总计”时会发生这种情况。

您的下拉列表是多选的，因此它将传递一个包含值的数组

使用

谢谢。这很有效，但我必须在此之前添加代码，以便从data post数组中捕获数组中的键值。我是这样做的。公共函数get_report6_10（$type，$data）{$dropdownSelections=array（）；foreach（$data['filter']as$key=>$value）{if（$key！=''）{array_push（$dropdownSelections，$key）；}$dropdownSelections=内爆（“，”，$dropdownSelections）；$select=''；if（$type=='natbuild'）{$select='和（'.$dropdownSelections.'）中的natbuild_principal.id；}//echo$select；

select sum(total) total

from (

    select value_of_sale total
    from lead
    left join natbuild_rep
    on natbuild_rep.mobile = lead.mobile
    left join natbuild_store
    on natbuild_store.id = natbuild_rep.store_id
    left join natbuild_principal
    on natbuild_principal.store_group = ifnull(natbuild_store.store_group2, natbuild_store.store_group)
where (status = 1 OR status = 2)
    and value_of_sale is not null
    and natbuild_principal.id in (18, 30, 31, 35, 33, 25, 23, 15, 8, 6, 5, 29, 7, 3, 2, 1, 24, 27, 22, 21, 20, 26, 36)
group by lead.id ) temp

 implode(",", $dropdownSelections);

 $select = 'and natbuild_principal.id in ('.implode(",", $dropdownSelections).')';
