                <div class="panel_s">
                    <div class="panel-body">

                        <!-- CONTEÚDO AQUI -->
                        <h4><?php echo _l('meu_modulo_title'); ?></h4>

## Carregar Views

### No Controller

```php
// Básico
$this->load->view('form');

// Com dados
$data = [
    'item' => $item,
    'clients' => $clients,
];
$this->load->view('form', $data);

// Retornar como string (não fazer echo)
$html = $this->load->view('partial', $data, true);
```

### Fora de Controllers (Helpers, Classes)

```php
function meu_modulo_render_widget()
{
    $CI = &get_instance();
    $CI->load->view('meu_modulo/widgets/dashboard');
}

// Com dados
function meu_modulo_render_table($items)
{
    $CI = &get_instance();
    $CI->load->view('meu_modulo/partials/_table', ['items' => $items]);
}
```

---

## Views Cliente (Área Cliente)

### No Controller (ClientsController)

```php
public function index()
{
    $this->data([
        'items' => $items,
        'title' => 'Meu Módulo',
    ]);
    $this->title(_l('meu_modulo_title'));
    $this->view('client_index');
    $this->layout(); // Aplica tema do cliente
}
```

### Template Base Cliente

```php
<?php defined('BASEPATH') or exit('No direct script access allowed'); ?>

<div class="panel_s">
    <div class="panel-body">
        <h4 class="no-margin"><?php echo _l('meu_modulo_title'); ?></h4>
        <hr class="hr-panel-heading" />

        <!-- CONTEÚDO -->
        <?php foreach ($items as $item): ?>
            <p><?php echo html_escape($item->name); ?></p>
        <?php endforeach; ?>

    </div>
</div>
```

echo html_escape($item->name);

// Para atributos HTML
echo html_escape($item->url, true);
```

### Formatação de Datas

```php
// Data formatada (configuração do sistema)
echo _d($item->date);           // 25-01-2026

// Data e hora
echo _dt($item->created_at);    // 25-01-2026 14:30
```

### Formatação de Valores

```php
// Moeda
echo app_format_money($item->amount, $currency);

// Número
echo app_format_number($item->quantity);
```

### Tradução

```php
// String de tradução
echo _l('meu_modulo_title');

// Com placeholder
echo _l('item_created_by', $staff_name);
```

## Anti-Patterns (NUNCA FAZER)

| Anti-Pattern | Risco | Alternativa |
|--------------|-------|-------------|
| Echo dados sem escape | XSS | `html_escape()` sempre |
| Não usar form_open() | CSRF vulnerável | Usar form_open() |
| SQL em views | Má arquitectura | Preparar no controller |
| Esquecer init_head/tail | Layout quebrado | Incluir sempre (admin) |
| Hardcode strings | Não traduzível | Usar `_l()` |

---

## Checklist View

```
1. [ ] defined('BASEPATH') no topo
2. [ ] init_head() e init_tail() (admin)
3. [ ] $this->layout() (cliente)
4. [ ] html_escape() em todos os dados user
5. [ ] form_open() para formulários
6. [ ] Permissões verificadas antes de mostrar botões
7. [ ] _l() para todas as strings
8. [ ] Classes CSS standard do Perfex
```
