提交表单时password_hash未更新 - password_hash not updating when submit form

当我提交表单时，如果提交了密码字段，它应该更新密码，否则如果为空，则不会更新密码。

我似乎无法更新password_hash，这很奇怪。我可以用它创建新用户，但不能更新那里的密码。

所有其他帖子都运行良好，更新良好

不确定为什么密码不更新？我如何才能解决问题，提前谢谢。

<?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');
        }
    }
}

仔细查看edit_user函数。您收到$data，但会立即覆盖它。请注意，您没有为新创建的数组设置password密钥。然后检查if ($data['password'])，但这永远不会是true，因此永远不会进行更新。

您的password_hash($_POST['password'], $options)中存在问题。您传递了$_POST['password']而不是$data['password']。

我花了一段时间才弄清楚，我需要在模型中的if语句之外创建另一个变量，如下所示，然后能够在出现新密码的情况下更新。

现在一切正常

$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);
}
