# 🔧 Fix Agent Topup Form Issue

## ❌ Masalah

Halaman `/mikhmon/?hotspot=agent-topup&session=XXX` tidak bisa topup saldo karena form conflict.

### Root Cause

Ada **2 form terpisah** dalam satu halaman:
1. Form untuk pilih agent (auto-submit on change)
2. Form untuk topup (submit button)

Ketika user klik "Proses Topup", yang ter-submit adalah form pertama (pilih agent), bukan form topup.

## ✅ Solusi

### Before (❌ Broken)

```php
<!-- Form 1: Pilih Agent -->
<form method="POST">
    <select name="agent_id" onchange="this.form.submit()">
        ...
    </select>
</form>

<!-- Form 2: Topup -->
<form method="POST">
    <input type="hidden" name="agent_id" value="...">
    <input name="amount" ...>
    <button type="submit" name="topup">Proses Topup</button>
</form>
```

**Problem:** 2 form terpisah, submit button tidak jelas form mana yang di-submit.

---

### After (✅ Fixed)

```php
<?php if ($agentData): ?>
<!-- Single Form: Topup -->
<form method="POST" id="topupForm">
    <input type="hidden" name="agent_id" value="<?= $agentId; ?>">
    
    <!-- Agent selector (no form, just redirect) -->
    <select onchange="window.location.href='...&agent_id=' + this.value">
        ...
    </select>
    
    <!-- Topup fields -->
    <input name="amount" ...>
    <button type="submit" name="topup">Proses Topup</button>
</form>
<?php else: ?>
<!-- No agent selected: Show selector only -->
<select onchange="window.location.href='...&agent_id=' + this.value">
    ...
</select>
<?php endif; ?>
```

**Solution:** 
- Hanya 1 form (form topup)
- Agent selector menggunakan `window.location.href` (redirect)
- Submit button jelas untuk form topup
