這是我的插入函數。它插入數據並在另一個視圖中顯示數據。但它有一個問題。如果我刷新它再次插入的視圖頁面。我想要防止再次插入刷新頁面。 plzzzzzzzzzzzzz如何停止插入數據到數據庫刷新頁面使用codeigniter

這是我controller.After插入數據,其結果是好的,到searching_view頁。但是當我刷新了searching_view頁面時,它再次插入數據。我想要避免再次插入數據來刷新searching_view頁面。
控制器
class car extends CI_Controller {
public function insert_controller() {
$data['search']=$this->m->insert_model();
$this->load->view('searching_view',$data);
}
}
它的模型。它插入數據,並從數據庫中獲取數據,並將結果發送。
模型
class add_model extends CI_Model {
public function insert_model()
{
if ($this->input->post('submit'))
{
date_default_timezone_set('Asia/Karachi');
$date=date('g:i A').' on '.date('F d,Y');
// echo "<pre>";
// die(print_r($date, TRUE));
$plate = $this->input->post('plate');
$phone = $this->input->post('phone');
$this->db->select('*');
$this->db->from('car');
$this->db->where('plate', $plate);
$this->db->or_where('phone', $phone);
$d = $this->db->get();
if ($this->db->affected_rows()>0)
{
redirect('http://localhost/Ci/index.php/Car/error_message2');
}
else
{
$arr= array(
'plate' => $this->input->post('plate'),
'maker' => $this->input->post('maker'),
'model' => $this->input->post('model'),
'year' => $this->input->post('year'),
'color' => $this->input->post('color'),
'drive' => $this->input->post('drive'),
'phone' => $this->input->post('phone'),
'name' => $this->input->post('name'),
'city' => $this->input->post('city'),
'country'=> $this->input->post('country'),
'date' => $date
);
$this->db->insert('car', $arr);
$id= $this->db->insert_id();
// fetching
$this->db->select('id,plate,maker,model,year,color,drive,phone,name,city,country');
$this->db->from('car');
$this->db->where('id', $id);
$d = $this->db->get();
return $d->result();
}
}
}
}
您的插入和列表方法應該不同。我的意思是在插入完成後,應該使用'redirect'而不是加載'searching_view' – jagad89
