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"); ?>

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。
关于php - 当我刷新我的页面时，它会自动将值输入到数据库 Codeigniter，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/18431783/
