如何在codeigniter中動態地將值數組發送到查詢

Question

模型中的代碼是 public function get_report6_8（$ type，$ filter_id = NULL）{values {array_filter}; $ filter = 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(); 
} 

在控制器中的代碼是 $數據[ '報告8'] = $這個 - > lead_report_model-> get_report6_8（$型，$這 - >輸入 - >交的（ '過濾器'））;

代碼視圖是

總計：$總））？ $ report8->總：0;>

如果我運行像

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 

查詢的結果都是正確的。請幫助我如何向$ select發送值數組。當我從包含所有其他值的下拉菜單中選擇總計時，會發生這種情況。

你的下拉菜單是多選的，所以它會傳遞一個數組。

使用

implode(",", $dropdownSelections); 

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