# CampaignPro Subscribe Shortcode + Embed

## 1) Standalone subscribe page

Use the page directly:

- `/subscribe`
- `/subscribe?theme=dark`
- `/subscribe?owner=2&list=default&button_text=Join%20Now`

In-app live preview studio:

- `/subscribe_preview`

## 2) Shortcode rendering (internal PHP pages)

Include the shared component and render shortcode markup:

```php
require_once __DIR__ . '/includes/init.php';
require_once __DIR__ . '/includes/subscribe_component.php';

echo campaignpro_render_subscribe_shortcode(
    '[campaignpro_subscribe owner="2" list="default" source="site_widget" theme="auto" button_text="Subscribe Now" layout="form"]'
);
```

## 3) Replace shortcodes inside content blocks

```php
$content = 'Before [campaignpro_subscribe owner="2" list="default" layout="form"] After';
echo campaignpro_replace_subscribe_shortcodes($content);
```

## 4) External site embed (iframe)

Generate URL:

```php
$url = campaignpro_subscribe_embed_url([
    'owner' => 2,
    'list' => 'default',
    'source' => 'external_website',
    'theme' => 'auto',
    'layout' => 'form'
]);
```

Or output full iframe:

```php
echo campaignpro_render_subscribe_iframe(
    ['owner' => 2, 'list' => 'default', 'source' => 'external_website', 'theme' => 'auto'],
    ['height' => '620']
);
```
