# 📧 PANDUAN INSTALASI EMAIL SCHEDULER

## Langkah 1: Persiapan Folder

Buat struktur folder seperti ini:

```
email-scheduler/
├── PHPMailer/          (akan dibuat di langkah 2)
├── uploads/            (buat folder ini)
├── email-scheduler.html
├── send-email.php
├── cron-send-emails.php
├── get-scheduled-emails.php
├── view-scheduled-emails.html
├── config.example.php
├── .htaccess
├── .gitignore
└── README.md
```

Buat folder uploads:
```bash
mkdir uploads
chmod 755 uploads
```

## Langkah 2: Install PHPMailer

### Opsi A: Menggunakan Composer (Recommended)

1. Install Composer jika belum ada:
```bash
php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');"
php composer-setup.php
php -r "unlink('composer-setup.php');"
```

2. Install PHPMailer:
```bash
php composer.phar require phpmailer/phpmailer
```

3. Edit file `send-email.php` dan `cron-send-emails.php`, ubah:
```php
// Uncomment baris ini:
require 'vendor/autoload.php';

// Comment baris-baris ini:
// require 'PHPMailer/src/Exception.php';
// require 'PHPMailer/src/PHPMailer.php';
// require 'PHPMailer/src/SMTP.php';
```

### Opsi B: Manual (Tanpa Composer)

1. Download PHPMailer:
   - Kunjungi: https://github.com/PHPMailer/PHPMailer
   - Klik "Code" > "Download ZIP"
   - Atau direct link: https://github.com/PHPMailer/PHPMailer/archive/master.zip

2. Extract file ZIP

3. Buat struktur folder:
```
email-scheduler/
└── PHPMailer/
    └── src/
        ├── Exception.php
        ├── PHPMailer.php
        ├── SMTP.php
        ├── OAuth.php
        └── POP3.php
```

4. Copy file dari folder `PHPMailer-master/src/` ke `email-scheduler/PHPMailer/src/`

5. File sudah siap digunakan dengan konfigurasi default

## Langkah 3: Konfigurasi SMTP

File sudah dikonfigurasi dengan:
- Host: mail.hostinger.com
- User: sunaryono@ibei.ac.id
- Pass: Sunaryono123!@#
- Port: 465 (SSL)

**Untuk keamanan lebih baik:**

1. Copy file config.example.php menjadi config.php:
```bash
cp config.example.php config.php
```

2. Edit file `send-email.php` dan `cron-send-emails.php`, tambahkan di awal:
```php
require 'config.php';
```

3. Hapus atau comment konfigurasi SMTP yang hardcoded

## Langkah 4: Test Instalasi

### Test 1: Cek PHP Version
```bash
php -v
```
Pastikan PHP 7.4 atau lebih tinggi

### Test 2: Cek Ekstensi PHP
```bash
php -m | grep openssl
php -m | grep mbstring
```
Pastikan kedua ekstensi terinstall

### Test 3: Test Kirim Email
1. Buka browser
2. Akses: `http://localhost/email-scheduler/email-scheduler.html`
3. Isi form dan kirim email test

## Langkah 5: Setup Cron Job (untuk Email Terjadwal)

### Di Linux/Ubuntu:

1. Buka crontab:
```bash
crontab -e
```

2. Tambahkan baris ini (jalankan setiap menit):
```
* * * * * /usr/bin/php /path/to/email-scheduler/cron-send-emails.php >> /path/to/email-scheduler/logs/cron.log 2>&1
```

3. Ganti `/path/to/email-scheduler/` dengan path lengkap folder Anda

4. Cari path PHP:
```bash
which php
```

### Di cPanel/Hostinger:

1. Login ke cPanel
2. Cari menu "Cron Jobs"
3. Set interval: `* * * * *` (setiap menit)
4. Command: `/usr/bin/php /home/username/public_html/email-scheduler/cron-send-emails.php`
5. Klik "Add Cron Job"

### Di Windows (Task Scheduler):

1. Buka Task Scheduler
2. Create New Task
3. Trigger: Every 1 minute
4. Action: Start a program
5. Program: `C:\php\php.exe`
6. Arguments: `C:\xampp\htdocs\email-scheduler\cron-send-emails.php`

## Langkah 6: Test Cron Job

Test manual:
```bash
php cron-send-emails.php
```

Cek log:
```bash
cat email_log.txt
```

## Langkah 7: Set Permission (Linux)

```bash
chmod 755 email-scheduler.html
chmod 755 send-email.php
chmod 755 cron-send-emails.php
chmod 755 get-scheduled-emails.php
chmod 755 view-scheduled-emails.html
chmod 755 uploads/
chmod 644 .htaccess
```

## Troubleshooting

### Error: "Class 'PHPMailer\PHPMailer\PHPMailer' not found"

**Solusi:**
- Pastikan folder PHPMailer/src/ ada dan berisi file yang benar
- Cek path require di file PHP
- Jika pakai Composer, jalankan: `composer install`

### Error: "SMTP connect() failed"

**Solusi:**
1. Cek kredensial SMTP (username/password)
2. Coba port alternatif:
   - Port 465 dengan SSL
   - Port 587 dengan TLS
3. Cek firewall server
4. Enable "Less secure app" di email (jika Gmail)
5. Untuk Hostinger, pastikan IP server tidak diblokir

### Email masuk spam

**Solusi:**
1. Setup SPF record di DNS
2. Setup DKIM di Hostinger
3. Gunakan email yang sama domain dengan SMTP
4. Hindari kata-kata spam di subject/body

### Permission denied untuk uploads/

**Solusi:**
```bash
chmod 755 uploads/
chown www-data:www-data uploads/  # Linux
```

### Cron job tidak jalan

**Solusi:**
1. Cek syntax crontab: `crontab -l`
2. Cek log: `tail -f /var/log/cron`
3. Test manual: `php cron-send-emails.php`
4. Cek path PHP: `which php`

## Keamanan

1. **Jangan commit password:**
```bash
echo "config.php" >> .gitignore
```

2. **Protect file sensitif dengan .htaccess:**
```apache
<FilesMatch "(config\.php|scheduled_emails\.json)$">
    Order allow,deny
    Deny from all
</FilesMatch>
```

3. **Gunakan HTTPS**

4. **Update password secara berkala**

5. **Batasi akses folder uploads**

## Port SMTP Alternatif

Jika port 465 bermasalah, gunakan port 587:

```php
define('SMTP_PORT', 587);
define('SMTP_SECURE', PHPMailer::ENCRYPTION_STARTTLS);
```

## Testing Email

Gunakan email testing untuk development:
- Mailtrap.io (free)
- MailHog (local)
- SendGrid (free tier)

## Backup

Backup file penting:
```bash
tar -czf backup-$(date +%Y%m%d).tar.gz email-scheduler/
```

## Update

Untuk update PHPMailer:
```bash
composer update phpmailer/phpmailer
```

Atau download versi terbaru dari GitHub

## Support

Jika ada masalah:
1. Cek dokumentasi: README.md
2. Cek log: email_log.txt
3. Enable debug mode di config.php
4. Hubungi support Hostinger
