Question

当我提交表单时，我的controller []数组帖子不起作用会引发错误。

错误1

遇到PHP错误严重性：通知消息：数组到字符串   转换文件名：mysqli / mysqli_driver.php行号：544

错误号：1054'字段列表'中的未知列'数组'INSERT INTO   user_group（name，controller，access，modify）价值观   （'Admin'，Array，'1'，'1'）文件名：   C：\ XAMPP \ htdocs中\ riwakawebsitedesigns \ SYSTEM \数据库\ DB_driver.php   行号：331

未插入控制器名称。不确定最好的修复方法吗？

模型

<?php

class Model_user_group extends CI_Model {

    public function addUserGroup($data) {
        $data = array(
            'name' => $this->input->post('name'),
            'controller' => $this->input->post('controller'),
            'access' => $this->input->post('access'),
            'modify' => $this->input->post('modify')
        );

        $this->db->set($data);
        $this->db->insert_id();
        $this->db->insert($this->db->dbprefix . 'user_group');
    }
?>

控制器

<?php

class Users_group extends Admin_Controller {

    public function index() {

        $data['title'] = "Users Group";

        $this->load->model('admin/user/model_user_group');

        $user_group_info = $this->model_user_group->getUserGroup($this->uri->segment(4));

        if ($this->input->post('name') !== FALSE) {
            $data['name'] = $this->input->post('name');
        } else {
            $data['name'] = $user_group_info['name'];
        }

        $ignore = array(
            'admin',
            'login',
            'dashboard',
            'filemanager',
            'login',
            'menu',
            'register',
            'online',
            'customer_total',
            'user_total',
            'chart',
            'activity',
            'logout',
            'footer',
            'header',
            'permission'
        );

        $data['controllers'] = array();

        $files = glob(FCPATH . 'application/modules/admin/controllers/*/*.php');

        foreach ($files as $file) {
            $controller =  basename(strtolower($file), '.php');

            if (!in_array($controller, $ignore)) {
                $data['controllers'][] = $controller;
            }
        }

        if ($this->input->post('name') !== FALSE) {
            $data['controller'] = $this->input->post('controller');
        } else {
            $data['controller'] = $user_group_info['controller'];
        }

        $this->load->library('form_validation');

        $this->form_validation->set_rules('name', 'User Group Name', 'required');

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

            $this->load->view('template/user/users_group_form.tpl', $data);

        } else {

            $this->load->model('admin/user/model_user_group');

            $this->model_user_group->addUserGroup($this->input->post());

            redirect('admin/users_group');

        }
    }
}

?>

Answer 1

您的controller隐藏字段是一个数组。您将此数组传递给addUserGroup函数，该函数尝试将此数组插入数据库。它隐含地尝试将此数组转换为字符串。也许尝试将您的功能更改为：

'controller' => $this->input->post('controller')[0],

Answer 2

错误是因为您无法在数据库中插入php-array。而是存储逗号分隔值。在您的模型中更改data数组，如下所示：

public function addUserGroup($data) {
    $controllers = $this->input->post('controller');
    $name = $this->input->post('name');   
    $access = $this->input->post('access');
    $modify = $this->input->post('modify');

    for($i=0;$i<count($controllers);$i++) {
     $data = array(
      'name' => $name,
      'controller' => $controllers[$i],
      'access' => $access,
      'modify' => $modify
    );

    $this->db->set($data);
    $this->db->insert_id();
    $this->db->insert($this->db->dbprefix . 'user_group');
    }
}

Answer 3

问题修复模型中的foreach感谢关于如何解决每个问题的想法。

foreach ($this->input->post('controller') as $controller) {
        $data = array(
            'name' => $this->input->post('name'),
            'controller' => $controller,
            'access' => $this->input->post('access'),
            'modify' => $this->input->post('modify')
        );

        $this->db->set($data);
        $this->db->insert_id();
        $this->db->insert($this->db->dbprefix . 'user_group');
}

模型不插入数组数据
