>我在 CI 中有一个方法，它基本上将用户添加到表中 - 如果发生任何表单验证，它会重新加载视图 - 如果成功，它会重新加载视图以显示用户已成功添加。如下所示：
public function loadPeopleView(){
//loads unit page view
$this->load->model('people_model');
$people['people'] = $this->people_model->getPeople();
$this->load->view("header");
$this->load->view("people page/people_view", $people);
$this->load->view("footer");
}
public function addPerson(){
$this->form_validation->set_rules('personName', 'personName', 'required|min_length[6]|max_length[150]|trim|xss_clean');
$this->form_validation->set_rules('personPet', 'personPet', 'required|trim|min_length[3]|max_length[30]|xss_clean');
if($this->form_validation->run()){
$this->load->model('');
$this->people_model->addPerson();
$this->loadPeopleView();
} else{
//if validation fails - returns the peopl view this display error messages
$this->loadPeopleView();
}
}
我的问题是当有人添加浏览器保持打开状态的人时：本地主机/人员控制器/添加人员
如果用户不断刷新页面 - 将继续添加大量人员 - 无论如何我都可以将页面放回：本地主机/人员控制器/
无需使用重定向，因为我仍然希望显示表单验证中的任何错误消息
我只给你一个例子，请根据保存和返回功能进行安排
public function addPerson(){
$this->load->model('people_model'); // load model
// validation
$this->form_validation->set_rules('personName', 'personName', 'required|min_length[6]|max_length[150]|trim|xss_clean');
$this->form_validation->set_rules('personPet', 'personPet', 'required|trim|min_length[3]|max_length[30]|xss_clean');
// check validation not clear
if ($this->form_validation->run() == FALSE) {
//if validation fails - returns the peopl view this display error messages
// also set error dat back
// setting up send back values to view
$this->data['personName'] = $this->input->post('personName');
$this->data['personPet'] = $this->input->post('personPet');
// get this->data values as a variable in view like $personName
// load view
$this->load->view("header");
$this->load->view("people page/people_view", $this->data);
$this->load->view("footer");
}
else{ // after validation success
// do your saving db stuff and set success message in session flash and redirect to
$this->people_model->addPerson();
// get and show message flash in your view
$this->session->set_flashdata('message', 'Please check card details and try again');
redirect('results', 'refresh');
}
}
