CodeIgniter 4 Shield 用戶管理

有效管理使用者帳戶對於任何 Web 應用程式都至關重要。 CodeIgniter 4 Shield 憑藉其強大的身份驗證和授權工具簡化了此任務。在這篇文章中，我們將探討使用 CodeIgniter 4 Shield 的使用者設定檔管理、密碼重設和復原以及帳戶已啟動和停用。

建立使用者設定檔檢視和表單

要管理使用者設定文件，您需要建立允許使用者查看和更新​​其資訊的視圖和表單。讓我們從建立基本的個人資料視圖和表單開始。

<?php

namespace App\Controllers;

use CodeIgniter\Controller;

class Profile extends Controller
{
    public function index()
    {
        $userModel = model('UserModel');
        $userId = auth()->id(); // Get current user ID
        $data['user'] = $userModel->find($userId);
        return view('profile_view', $data);
    }

    public function update()
    {
        $userModel = model('UserModel');
        $userId = auth()->id(); // Get current user ID

        $userModel->update($userId, [
            'username' => $this->request->getPost('username'),
            'email' => $this->request->getPost('email'),
        ]);

        return redirect()->to('/profile')->with('success', 'Profile updated successfully.');
    }
    public function resetPassword()
    {
        $email = $this->request->getPost('email');
        $userModel = model('UserModel');
        $user = $userModel->where('email', $email)->first();

        if ($user) {
            // Send reset link via email (implement email sending)
            // For simplicity, we just log a message here
            log_message('info', 'Password reset link sent to ' . $email);
        }

        return redirect()->to('/')->with('message', 'If the email is registered, a reset link will be sent.');
    }

    public function reset()
    {
        $token = $this->request->getPost('token');
        $newPassword = $this->request->getPost('new_password');
        $userModel = model('UserModel');

        // Validate token and reset password
        // For simplicity, token validation is skipped here
        $user = $userModel->where('reset_token', $token)->first();
        
        if ($user) {
            $userModel->update($user['id'], [
                'password' => password_hash($newPassword, PASSWORD_DEFAULT),
                'reset_token' => null // Clear reset token
            ]);

            return redirect()->to('/login')->with('success', 'Password reset successfully.');
        }

        return redirect()->to('/')->with('error', 'Invalid token.');
    }
    public function activate($token)
    {
        $userModel = model('UserModel');
        $user = $userModel->where('activation_token', $token)->first();

        if ($user) {
            $userModel->update($user['id'], [
                'is_active' => true,
                'activation_token' => null // Clear activation token
            ]);

            return redirect()->to('/login')->with('success', 'Account activated successfully.');
        }

        return redirect()->to('/')->with('error', 'Invalid activation token.');
    }

    public function deactivate()
    {
        $userId = auth()->id(); // Get current user ID
        $userModel = model('UserModel');

        $userModel->update($userId, [
            'is_active' => false
        ]);

        return redirect()->to('/login')->with('success', 'Account deactivated. Please contact support to reactivate.');
    }
