mysql - 如果数据存在，则 Form_validation 未运行

Question

我编辑了以下代码，以使其与我所做的更改保持同步。我已成功保存它但是，当重定向完成时，我仍然无法显示“成功”消息。另外，如果出现不正确错误，我该如何保存输入的数据？

Controller

class Addsale extends CI_Controller {

function __construct(){
parent::__construct();
}
function index() {
    if(!$this->session->userdata('logged_in')) {
        redirect('admin/home');
    }
    // set data
    $data['title'] = "Add Sale";
    $data['sales_pages'] = $this->sales_model->getSalesPages();
    $data['cms_pages'] = $this->navigation_model->getCMSPages();

    $this->load->library('form_validation');
    $this->form_validation->set_rules('name', 'Name', 'trim|required');
    $this->form_validation->set_rules('location', 'Location', 'trim|required');
    $this->form_validation->set_rules('bedrooms', 'Bedrooms', 'trim|is_natural|required');
    $this->form_validation->set_rules('bathrooms', 'Bathrooms', 'trim|required');
    $this->form_validation->set_rules('condition', 'Condition', 'trim|required');
    $this->form_validation->set_rules('description', 'Description', 'trim|required');
    $this->form_validation->set_rules('price', 'Price', 'trim|required');

    if($this->form_validation->run() === TRUE) {

    $data = array(  
        'name' => $this->input->post('name', TRUE),
        'location' => $this->input->post('location', TRUE),
        'bedrooms' => $this->input->post('bedrooms', TRUE),
        'bathrooms' => $this->input->post('bathrooms', TRUE),
        'condition' => $this->input->post('condition', TRUE),
        'description' => $this->input->post('description', TRUE),
        'price' => $this->input->post('price', TRUE)
        );

        $this->sales_model->addSale($data);

        redirect('admin/addsale' , $data);

        $this->session->set_flashdata('success', 'Page Saved');

    }else{
        $data['content'] = $this->load->view('admin/addsale', NULL, TRUE);
        $this->load->view('template', $data);
        }

}


    }

function addSale($data) {

$this->db->insert('sales', $data);
return;

您正在使用 set_message 来显示“已完成”消息？如果是这样，则不会显示该内容，因为您在其之前进行了重定向。

尝试在重定向之前在 flashdata 中设置一条消息，如下所示:

$this->session->set_flashdata('success', 'Page Saved');

然后在您的 View 中打印出来:

print $this->session->flashdata('success')
