我有一个要提交到数据库的表格。如果不使用is_unique验证规则,它将非常有效。当我尝试将其放入代码中时,我收到一条错误消息,说我尝试用于它的每个字段都需要一个唯一的值。问题是我正在将数据插入我不知道的数据库中。这是我的代码:

控制器:

function submit_register() {

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

        $this->form_validation->set_rules('first_name', 'First Name', 'required|max_length[30]|xss_clean');
        $this->form_validation->set_rules('last_name', 'Last Name', 'required|max_length[30]|xss_clean');
        $this->form_validation->set_rules('email', 'E-Mail', 'required|max_length[30]|valid_email|is_unique[users.email]|xss_clean');
        $this->form_validation->set_rules('username', 'Username', 'required|max_length[30]|is_unique[users.username]|xss_clean');
        $this->form_validation->set_rules('password', 'Password', 'required|max_length[30]|xss_clean');
        $this->form_validation->set_rules('password_confirmation', 'Password Confirmation', 'required|max_length[30]|matches[password]|xss_clean');

        if ($this->form_validation->run($this) == FALSE) {
                $this->register();
        }
        else {
                $data = array(
                'first_name' => $this->input->post('first_name'),
                'last_name' => $this->input->post('last_name'),
                'email' => $this->input->post('email'),
                'username' => $this->input->post('username'),
                'password' => $this->input->post('password'),
                );
                $this->load->model('mdl_users');
                $this->mdl_users->_register_user($data);
                redirect("http://localhost:8888");
        }
    }


模型:

function _register_user($data) {
        $salt = bin2hex(openssl_random_pseudo_bytes(22));
        $encrypted_password = md5($data['password'].''.$salt);

        $data = array(
            'first_name' => $data['first_name'],
            'last_name'  => $data['last_name'],
            'email'      => $data['email'],
            'username'   => $data['username'],
            'password'   => $encrypted_password,
            'salt'       => $salt,
            'user_level' => 'user',
            'created_at' => date('Y-m-d H:i:s'),
            'updated_at' => date('Y-m-d H:i:s')
        );

        $this->db->insert('users', $data);
        }


我在CodeIgniter手册中阅读了以下内容:

Note: This rule requires Query Builder to be enabled in order to work.


这是我所缺少的吗?如果是这样,我找不到如何执行此操作的答案。

最佳答案

你错过了吗?

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


您可以使用此视图检查is_unique是否正常工作。

<?php if(validation_errors()) echo validation_errors(); ?>
