您好我在使用codeigniter保存数据库中的所有多个数据时遇到此问题。我在传递数据时使用ajax，我想在其中保存多个数据，但我的问题是我不知道该怎么做。有人可以帮助我吗？ 这是我的控制器
class News_and_events extends CI_Controller {
public function __construct(){
parent::__construct();
$this->load->library('form_validation');
$this->load->model('admin_model', 'am');
$this->load->library('session');
}
public function add_another(){
$added_datas = $this->input->post('added_datas');
$added_arr = explode("|", $added_datas);
foreach($added_arr as $value){
if($value){
$pass_arr = explode("*", $value);
$items = array();
$items[] = array(
'Date' => $this->input->post($items[0]),
'Event' => $this->input->post($items[1]),
'Description' => $this->input->post($items[2])
);
$this->am->saveData($items[]);
}
}
}
}
我的模特
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
Class Admin_model extends CI_Model{
public function editData($id){
return $this->db->get_where('news_and_updates',array('id' => $id))->row_object();
}
public function saveData($array){
$this->db->insert('news_and_updates', $array);
}
public function getAllData(){
return $this->db->order_by("Date", "desc")
->get('news_and_updates')
->result_object();
}
public function delete($id){
$this->db->where('id', $id)->delete('news_and_updates');
}
}
?>
