Question

我是CI的新手。我想用循环向DB添加一些记录。我控制器中的内容是：

$client_name = $this->input->post('client_name');
            $contact_person_details = array($this->input->post('contact_person_name_1'),
                                          $this->input->post('contact_person_phone_1'),
                                          $this->input->post('contact_person_email_1'),
                                          $this->input->post('contact_person_name_2'),
                                          $this->input->post('contact_person_phone_2'),
                                          $this->input->post('contact_person_email_2'),
                                          $this->input->post('contact_person_name_3'),
                                          $this->input->post('contact_person_phone_3'),
                                          $this->input->post('contact_person_email_3'),
                                        );
            $this->common_model->dbinsert_contactpersons('ci_contact_persons', $contact_person_details, $client_name);

然后在我的模型中：

function dbinsert_contactpersons ($tablename, $details, $client_name) {
    for ($i=0; $i<=3; $i++) {
        $w = 3*$i;
        $j = $w+1;
        $k = $w+2;
        $insert_detail = array('client'             => $client_name,
                            'contact_person_name'   => $details[$w],
                            'contact_person_phone'  => $details[$j],
                            'contact_person_email'  => $details[$k]
                            );
        if($this->db->insert ($tablename, $insert_detail))
        {
            return true;
        }
        else
        {
            return false;
        }
    }
}

代码将第一个联系人详细信息插入到数据库中（contact_person_name_1，contact_person_phone_1，contact_person_email_1），但不插入其余的...当我var_dump数组$ contact_person_details时，值就在那里。感谢您的建议...

开始编辑＆gt; 我试图优化控制器并摆脱数组，如果有这样的空值：

$contacts_data = array();
            for ($i=1; $i<=3; $i++) {
                if ($this->input->post('contact_person_name_'.$i) != "") {
                    $contacts_data['client'] = $this->input->post('client_name');
                    $contacts_data['contact_person_name'] = $this->input->post('contact_person_name_'.$i);
                    $contacts_data['contact_person_phone'] = $this->input->post('contact_person_phone_'.$i);
                    $contacts_data['contact_person_email'] = $this->input->post('contact_person_email_'.$i);
                }
            }

显然，有错误......有没有正确的方法呢？

您可以将数组发送到模型并在一行中执行多次插入：

控制器：

$data = array(
   array(
      'client' => $this->input->post('client_name') ,
      'contact_person_name' => $this->input->post('contact_person_name_1') ,
      'contact_person_phone' => $this->input->post('contact_person_phone_1'),
      'contact_person_email' => $this->input->post('contact_person_email_1'),
   ),
   array(
     'client' => $this->input->post('client_name') ,
      'contact_person_name' => $this->input->post('contact_person_name_2') ,
      'contact_person_phone' => $this->input->post('contact_person_phone_2'),
      'contact_person_email' => $this->input->post('contact_person_email_2'),
   )
);
 $this->common_model->dbinsert_contactpersons('ci_contact_persons', $data);

型号：

function dbinsert_contactpersons ($tablename, $data) 
{
     $this->db->insert_batch($tablename, $data);
}

您可以使用循环和数组（例如contact_person_name []）优化控制器部分。
