# Popup Notices: Developer Hooks, Filters and Shortcodes Reference

[Popups for WooCommerce: Add to Cart, Checkout & More](https://wpfactory.com/item/popup-notices-for-woocommerce/) exposes filters and actions so you can change the modal markup, control when the plugin loads, add restrictive-loading conditionals, and adjust the notices it targets, all in code. Every hook below is prefixed `ttt_pnwc_` and was verified against the plugin source for v1.5.4.

### Template and markup filters

| Filter | Filtered value | Notes |
| --- | --- | --- |
| `ttt_pnwc_modal_template` | The full modal HTML string. | Must keep the `{header_content}` and `{footer_content}` placeholders and the `ttt-pnwc-content` container. |
| `ttt_pnwc_header_content` | Header HTML (default: the close button). | Replaces `{header_content}`. |
| `ttt_pnwc_footer_content` | Footer HTML (default: empty). | Replaces `{footer_content}`. Pro uses it for the internal close button. |
| `ttt_pnwc_notice_selector` | The CSS selector for a hidden native notice. | Second argument is the context: `error_wrapper`, `success`, or `info`. Defaults are `.woocommerce-error`, `.woocommerce-message`, `.woocommerce-info`. |

### Loading and localization filters

| Filter | Filtered value | Notes |
| --- | --- | --- |
| `ttt_pnwc_is_allowed_to_load` | Boolean: should the plugin load on this request. | Return `false` to stop scripts loading. This is how Restrictive Loading works. |
| `ttt_pnwc_current_page_allowed` | Boolean for the page check. | Second argument is the allowed pages array. |
| `ttt_pnwc_conditionals_options` | Associative array of conditional callbacks for Restrictive Loading. | Key is a callable name, value is the label. Pro adds `is_cart`, `is_checkout`, `is_shop`, and others. |
| `ttt_pnwc_localize_script` | The `ttt_pnwc_info` data array passed to the frontend script. | Holds notice types, AJAX, cookie, audio, auto-close, and ignored-message data. |
| `ttt_pnwc_admin_localize_script` | The admin script data array. | Used on the settings and Customizer screens. |
| `ttt_pnwc_frontend_js_modules_required` / `ttt_pnwc_admin_js_modules_required` | Array of JS module names to load. | Advanced; used to request optional bundled modules. |

### Settings filters

| Filter | Filtered value |
| --- | --- |
| `ttt_pnwc_settings_general` | The General section settings array. |
| `ttt_pnwc_settings_compatibility` | The Compatibility section settings array. |
| `ttt_pnwc_settings_messages` | The Messages section settings array. |
| `woocommerce_get_sections_ttt-pnwc` | The array of settings sub-sections (tab id `ttt-pnwc`). |
| `ttt_pnwc_license_data` | Internal free/premium data used to gate fields. Do not rely on it in third-party code. |

### Action

`pnwc_autoloader` fires with the autoloader instance so add-on code can register a namespace: `add_action( 'pnwc_autoloader', function( $autoloader ) { $autoloader->add_namespace( 'My\Namespace', $path ); } );`

### Shortcodes (Pro)

| Shortcode | Attributes | Purpose |
| --- | --- | --- |
| `[ttt_pnwc_get_message]` | `filter` | Returns the current text of the named WooCommerce message filter. |
| `[ttt_pnwc_product_image]` | `product_id`, `image_size` (default `woocommerce_gallery_thumbnail`) | Outputs a product's image. |

### Example: change the hidden success-notice selector

```
add_filter( 'ttt_pnwc_notice_selector', function( $selector, $context ) {
    if ( 'success' === $context ) {
        $selector = '.woocommerce-message, .my-theme-success';
    }
    return $selector;
}, 10, 2 );
```
