Parameters

• $otp (string): The generated OTP code.
• $phoneNumber (string): The phone number associated with the OTP.
• $agent (string): The agent associated with the OTP.

/**
 * Sends an email notification when an OTP is generated.
 *
 * @param string $otp The generated OTP code.
 * @param string $phoneNumber The phone number associated with the OTP.
 * @param string $agent The agent associated with the OTP.
 */
function send_otp_email_notification($otp, $phoneNumber, $agent) {
    // Get the user information by phone number
    $user = \WP_SMS\Helper::getUserByPhoneNumber($phoneNumber);

    // Get the current user's email
    if (is_user_logged_in()) {
        $current_user = wp_get_current_user();
        $email = $current_user->user_email;
    } elseif ($user) {
        // Use the email from the user fetched by phone number
        $email = $user->user_email;
    } else {
        // If no user is found, handle accordingly (e.g., log an error, skip sending email)
        error_log('No user found with the given phone number.');
        return;
    }

    $subject = 'Your OTP Code';
    $message = "Hello,

Your OTP code is: $otp

Phone Number: $phoneNumber
Agent: $agent

Thank you.";

    // Optional: Set additional headers.
    $headers = array(
        'Content-Type: text/plain; charset=UTF-8',
        'From: [email protected]',
        'Reply-To: [email protected]'
    );

    // Send the email using wp_mail.
    wp_mail($email, $subject, $message, $headers);
}

// Hook the function to the custom action.
add_action('wp_sms_otp_generated', 'send_otp_email_notification', 10, 3);
