This article will introduce how to use the email verification function in the ThinkPHP framework.

1. What is ThinkPHP email verification

Before using ThinkPHP for email verification, you should first understand what ThinkPHP email verification is. The email verification provided by the ThinkPHP framework is a method of verifying user identity through email. It can ensure that the email entered by the user is authentic and that the user can use this email address to receive and send emails.

2. How to use ThinkPHP for email verification

1. Preparation work

Before using ThinkPHP for email verification, you need to install ThinkPHP first and make sure it has been Configure the database connection. At the same time, you need to install an SMTP mail server in the development environment to send verification emails.

2. Create a user registration page

First, you need to create a user registration page for users to enter their email addresses when registering. Add a form element to the page so that users can enter their email address. The sample code is as follows:

<form action="register.php" method="post">
  <label for="email">请填写您的邮箱:</label>
  <input type="email" name="email" id="email">
  <input type="submit" value="注册">
</form>

3. Write an email sending method

In the background code, you need to write A method for sending verification emails. You can use a third-party email sending library such as PHPMailer, or you can use PHP's built-in email sending function mail(). The email content should contain a verification link for users to click to jump to the verification page to verify the user's email address.

public function sendVerifyEmail($to, $token)
{
    $url = 'http://example.com/verify.php?token=' . $token;
    $body = <<<EOT
    尊敬的用户，您好！
    
    感谢您在我站注册了新账户。
    
    请点击此链接验证您的邮箱地址：
    
    {$url}
    
    若您没有进行过此操作，请忽略此邮件。
    
    – 您的好友
    EOT;
    
    $mail->addAddress($to);
    $mail->Subject = '请验证您的email';
    $mail->Body = $body;
    $mail->send();
}

4. Add email verification route

In the ThinkPHP framework, routing is the basic configuration for parsing URL addresses and sending requests to specified controllers. In this example, you need to add a route for email verification.

Route::get('email-verification/:token', 'User/emailVerification');

5. Write email verification method

In the background code, you need to write a method for email verification, which is used to verify the user's email address. After successful verification, the user's email verification status needs to be updated to the database so that other pages can determine whether the user has passed email verification.

public function emailVerification($token)
{
    $user = User::where('email_token', $token)->first();
    if (!$user) {
        abort(404);
    }
    
    $user->email_verified = true;
    $user->email_token = null;
    $user->save();
    
    return redirect('/login')->with('success', '邮箱验证成功！请登录');
}

6. Integrated email verification

When registering a user, the user's email address and a randomly generated verification token need to be stored in the database. Subsequently, call the send email method written above to send a verification email to the user's email address. When the user clicks the link in the verification email, the system will access the verification page and execute the email verification method.

public function register(Request $request)
{
    $this->validate($request, [
        'email' => 'required|email|unique:users,email',
        'password' => 'required|min:6'
    ]);
    
    $user = User::create([
        'email' => $request->email,
        'password' => bcrypt($request->password),
        'email_token' => str_random(32)
    ]);
    
    $this->sendVerifyEmail($user->email, $user->email_token);
    
    return redirect('/login')->with('success', '新用户注册成功！请前往您的邮箱验证。');
}
