Question

我想使用codeigniter在数据库中插入多行，但是我不知道如何正确实现它以使程序正常工作。我想要的是从accounts表中获取数据，并在if else语句中使用其属性之一作为验证参数。如果满足条件，它将用公告表内容以及满足适当条件的所有帐户的用户ID填充表。你能帮我解决这个问题吗？谢谢。

这是我的代码段。

控制器

public function announceSubmit(){
        $this->session->userdata('user_data');
        $id = $this->session->userdata('user_id');
        $uType = $this->session->userdata('user_type');
        $title = $this->input->post('title', true);
        $users = $this->input->post('users', true);
        $content = $this->input->post('descr', true);

        $config['upload_path'] = './uploads/announcements/';
        $config['allowed_types'] = 'jpg|png|jpeg';
        $config['max_size'] = '25000';

        $this->load->library('upload',$config);

            if(!$this->upload->do_upload('image-source')){
                print_r($this->upload->display_errors());
            }else{

                $newData = $this->Bid_Model->fetchItems('accounts');


                if($users == $uType){

                    foreach($newData as $user):
                        $userIDs = $user->user_id;
                    endforeach;

                        $announce_image = $this->upload->data('file_name');

                        $data = array(
                            'title' => $title,
                            'user_type' => $users,
                            'content' => $content,
                            'image' => $announce_image,
                            'admin_user_id' => $id,
                            'user_id' => $userIDs
                        ); 

                        $this->Bid_Model->insertItem('announcements', $data);
                }


                redirect('dashboard');
            }
        }

Answer 1

假定所有传递给insertItems的数据都已清除，并且您想直接将其插入DB中而无需进行任何更改。

数据库功能：

function insert_batch($data) {
   $query = 'INSERT INTO TABLE (`title`, `user_type`, `content`, `image`, 
                                `admin_user_id`, `user_id`) VALUES ';
   $insert_data = [];
   for($x=0; $x<count($data); $x++){
    $insert_data[] = "('" . $data['title'] . "', '" . $data['user_type'] . "', '" . $data['content'] . "', '" . $data['image'] . "', '" . $data['admin_user_id'] . "','" . $column2['user_id'] . "')";
    }
    $query .= implode(',', $insert_data); //Execute this $query
}

Answer 2

由于您已经说过要插入多行，所以我假设您想使用先前从NAME ID A B C XDSFD SMH19 16 RTRE DDF33X <- this row should be matched with 1st row from table above cause ID is matching 107029271 TABAU_USD_DFS_MR14 4 YTY TTD <- this row should be matched with 4th and 6th row from first table 107029271 BLY_UU_OMO6 43 CCCTR CVBTW <- this row shouldn't be matched with anything cause even while there is override with the same NAME that override requires also to have matching ID函数中选择的数据进行批量插入。您可以这样尝试：
