Change the passwordThinkPHP:

With the popularity of social networks and e-commerce , more and more websites require account management. Account security is one of the biggest concerns for users. Therefore, it is essential to provide the function of changing passwords. This article will introduce how to implement the password modification function in ThinkPHP.

To change the password in ThinkPHP, the following steps are required:

1. Get the old password, new password and confirm the new password submitted by the user
2. Verify whether the old password is correct
3. Verify whether the new password and confirm the new password are consistent
4. Save the new password in the database

The page to change the password can be implemented using an HTML form, the code is as follows:

<form method="POST" action="{:url(&#39;User/changePwd&#39;)}">
  <label>旧密码：</label>
  <input type="password" name="old_pwd">

  <label>新密码：</label>
  <input type="password" name="new_pwd">

  <label>确认新密码：</label>
  <input type="password" name="confirm_pwd">

  <button type="submit">修改密码</button>
</form>

In the controller, you can use the following code to implement the function of changing the password:

public function changePwd($old_pwd, $new_pwd, $confirm_pwd)
{
    $user = UserModel::get($this->userId); // 获取当前用户信息

    // 验证旧密码是否正确
    if (!$user->checkPassword($old_pwd)) {
        $this->error('旧密码不正确');
    }

    // 验证新密码和确认新密码是否一致
    if ($new_pwd !== $confirm_pwd) {
        $this->error('新密码和确认密码不一致');
    }

    // 将密码加密后保存到数据库中
    $user->password = password_hash($new_pwd, PASSWORD_DEFAULT);
    $user->save();

    $this->success('密码修改成功');
}

It should be noted that the password_hash function should be used to encrypt the new password when saving the password. In addition, in order to increase the complexity of the password, the password length should be limited and contain uppercase letters, lowercase letters, numbers and special characters.

Summary:

In ThinkPHP, the process of changing a user's password includes obtaining the old password, new password and confirming the new password submitted by the user, verifying whether the old password is correct, verifying the new password and confirming the new password. Check whether the passwords are consistent and save the new password to the database.
