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>舊密碼：</label>
??<input type="password" name="old_pwd">

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

??<label>確認(rèn)新密碼：</label>
??<input type="password" name="confirm_pwd">

??<button type="submit">修改密碼</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);?//?獲取當(dāng)前用戶信息

????//?驗(yàn)證舊密碼是否正確
????if?(!$user->checkPassword($old_pwd))?{
????????$this->error('舊密碼不正確');
????}

????//?驗(yàn)證新密碼和確認(rèn)新密碼是否一致
????if?($new_pwd?!==?$confirm_pwd)?{
????????$this->error('新密碼和確認(rèn)密碼不一致');
????}

????//?將密碼加密后保存到數(shù)據(jù)庫中
????$user->password?=?password_hash($new_pwd,?PASSWORD_DEFAULT);
????$user->save();

????$this->success('密碼修改成功');
}

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. In order to ensure the security of passwords, password length should be limited and contain uppercase letters, lowercase letters, numbers, and special characters.
