一起刪除幾行mysql數據庫？

Question

我想用「codeigniter」中的複選框選中後刪除「多行mysql數據庫」，但我的功能不起作用:(我的問題在「function delete（）」）。它是什麼？

function delete(){ 
    $delete = $this->input->post('delete'); // this is array => "delete[]" . value this is "id" it row in database. 
    for($i=0;$i<count($delete);$i++) { 
     $this->db->delete('My_Table', array('id' => $delete[$i])); 
    } 
    } 

Answer 1

一旦你的ID陣列在$delete變量，你可以做到以下幾點：

if(is_array($delete) && count($delete) > 0) 
{ 
    $this->db->query("DELETE FROM `My_Table` WHERE `id` IN (" . implode(", ", $delete) . ")"); 
}
