Question

模型中的代码是 public function get_report6_8（$ type，$ filter_id = NULL）{ $ values = array（$ filter_id）;

$select = '';       
if ($filter_id && $type == 'jh') {
    $select = 'and natbuild_rep.jh_rep_id = ?';
}
else if ($filter_id && $type == 'natbuild') {
    $select = 'and natbuild_principal.id = ?';
}

$sql = "select sum(total) total
    from (
        select value_of_sale total
        from lead
        left join natbuild_rep
        on natbuild_rep.mobile = lead.mobile
        left join natbuild_store
        on natbuild_store.id = natbuild_rep.store_id
        left join natbuild_principal
        on natbuild_principal.store_group = ifnull(natbuild_store.store_group2, natbuild_store.store_group)
        where (status = 1 OR status = 2)
        and value_of_sale is not null
        {$select}
        group by lead.id
    ) temp";

return $this->db->query($sql, $values)->row();
}

控制器中的代码是 $ data ['report8'] = $ this-＆gt; lead_report_model-＆gt; get_report6_8（$ type，$ this-＆gt; input-＆gt; post（'filter'））;

视图中的代码是

总计：$ total））？ $ report8-＆gt;总计：0;？＆gt;

如果我运行像

这样的查询

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

结果是对的。请帮助我如何向$ select发送值数组。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。

Answer 1

你的下拉列表是多选的，所以它将传递一个带有值的数组。

使用

 implode(",", $dropdownSelections);

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

如何在codeigniter中动态地向查询发送值数组
