Question

如果我提交了我的表单，如果提交了密码字段，则应该更新密码，否则如果为空则不更新密码。

我似乎无法让password_hash更新非常奇怪。我可以使用它创建新用户，但不能更新密码。

所有其他帖子工作正常。

不确定为什么密码不更新？我如何能够提前解决问题。

<?php

class Model_user extends CI_Model {

    public function edit_user($user_id, $data) {

        $data = array(
            'username' =>  $data['username'],
            'user_group_id' =>  $data['user_group_id'],
            'firstname' => $data['firstname'],
            'lastname' => $data['lastname'],
            'email' => $data['email'],
            'image' => $data['image'],
            'status' => $data['status']
        );

        $this->db->set($data);
        $this->db->where('user_id', $user_id);
        $this->db->update($this->db->dbprefix . 'user');

        if ($data['password']) {

            $options = [
                'cost' => 11,
                'salt' => mcrypt_create_iv(22, MCRYPT_DEV_URANDOM),
            ];

            $data = array(
                'password' => password_hash($_POST['password'], $options)
            ); 

            $this->db->set($data);
            $this->db->where('user_id', $user_id);
            $this->db->update($this->db->dbprefix . 'user');
        }

    }
}

Answer 1

仔细查看edit_user功能。您收到$data但会立即覆盖它。请注意，您不必为新创建的阵列设置password密钥。然后，您检查if ($data['password'])，但永远不会true，因此永远不会进行更新。

Answer 2

password_hash($_POST['password'], $options)存在问题。您通过了$_POST['password']而不是$data['password']。

Answer 3

我需要一段时间来弄清楚我需要在我的模型中创建if语句的另一个变量，如下所示，然后能够更新是否存在新密码。

现在全部工作。

$input_password = $this->input->post('password');

if ($input_password) {
$password = password_hash($input_password, PASSWORD_BCRYPT);

$data_password = array(
'password' => $password
); 

$this->db->where('user_id', $user_id);
$this->db->update($this->db->dbprefix . 'user', $data_password);
}

提交表单时，password_hash不会更新
