数据不会插入数据库（Codeigniter3）

Question

我的问题是每次点击提交按钮数据都不会插入数据库

数据库配置文件配置得很好，但我不知道问题来自哪里

这是文件： 控制器：

class Store_items extends MX_Controller {

    function __construct() {
        parent::__construct();
    }

    function create() {

        $this->load->module('site_security');
        $this->site_security->_make_sure_is_admin();

        $update_id = $this->uri->segment(3);
        $submit = $this->input->post('submit', TRUE);
        if ($submit == "Submit") {
            $this->load->library('form_validation');
            $this->form_validation->set_rules('item_title', 'Item Title', 'required|max_length[240]');
            $this->form_validation->set_rules('item_price', 'Item Price', 'required|numeric');
            $this->form_validation->set_rules('was_price', 'Was Price', 'numeric');
            $this->form_validation->set_rules('item_description', 'Item Description', 'required');
            if ($this->form_validation->run($this) == TRUE) {
                $data = $this->fetch_data_from_post();
                if (is_numeric($update_id)) {
                    //update
                    $this->_update($update_id, $data);
                    $flash_msg = "Le produit est mise à jour avec succes.";

                    $value = '<div class="alert alert-success" >' . $flash_msg . '</div>';

                    redirect('store_items/create/' . $update_id);//remember the flash data

                }
            }
        }

        if ((is_numeric($update_id)) && ($submit != "Submit")) {

这里是名为Create.php的视图文件，我将插入所有数据 到数据库。

Answer 1

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

将run($this)更改为run()

Form_validation方法run()参数

$group (string) -- The name of the validation group to run
