我使用 codeigniter 创建了一个。当用户第一次来到表单页面时,用户提交值,然后将值存储到数据库中,用户再次被定向到表单页面。现在的问题是,如果用户在第一次提交表单后刷新页面,那么当用户刷新页面时,最后插入的值会一次又一次地自动添加到数据库中如何停止???

这是我的查看代码...

        <?php echo form_open("site/upload_data"); ?>

<input type="submit" value="Submit" />
</div>
</div>

<?php echo form_close(); ?>

</div>

这是我的 Controller 代码...

public function upload_data()

{

$this->load->library('form_validation');
// field name, error message, validation rules
$this->form_validation->set_rules('movie_name', 'Movie Name', 'trim|required|min_length[4]|xss_clean');
$this->form_validation->set_rules('date', 'date', 'trim|required|min_length[4]|xss_clean');
$this->form_validation->set_rules('genres', 'genres', 'trim|required|min_length[4]|xss_clean');


$this->form_validation->set_rules('star', 'star', 'trim|required|min_length[4]|xss_clean');

$this->form_validation->set_rules('director', 'director', 'trim|required|min_length[4]|xss_clean');

$this->form_validation->set_rules('writers', 'writers', 'trim|required|min_length[4]|xss_clean');
$this->form_validation->set_rules('path', 'path', 'trim|required|min_length[4]|xss_clean');


if($this->form_validation->run() == FALSE)
{
$this->admin();
}
else
{
$result = $this->site_upload->add_data();

if ($result)
{
$this->load->view('admin');
}
}
}

这是我的模型代码...

public function add_data()
{
$values = array (
'movie_name' => $this->input->post('movie_name'),
'date' => $this->input->post('date'),
'genres' => $this->input->post('genres'),
'rating' => $this->input->post('rating'),
'star' => $this->input->post('star'),
'director' => $this->input->post('director'),
'writers' => $this->input->post('writers'),
'path' => $this->input->post('path')
);

$rows = $this->db->insert('data',$values);

return $rows;
}

最佳答案

if($this->form_validation->run() == FALSE)
{
$this->admin();
}
else
{
$result = $this->site_upload->add_data();

if ($result)
{
redirect('/path/you/want/to/redirect'); //do the redirection
}
}

redirect() 将达到目的。
