# lzb_pro/plugin_path [Pro]

Filters the absolute path Lazy Blocks Pro loads its own class files and build assets from.

The Pro plugin bundled inside a theme or a parent plugin sits somewhere `plugin_dir_path( __FILE__ )` still reports correctly, so this filter is rarely needed. It exists as the counterpart of [lzb_pro/plugin_url](https://www.lazyblocks.com/docs/php-filters/lzb_pro-plugin_url/), for a setup that moves the files after the plugin header has been read.

## Attributes

| Name           | Type       | Description                                                                   |
| -------------- | ---------- | ----------------------------------------------------------------------------- |
| `$plugin_path` | **String** | `plugin_dir_path( __FILE__ )` of `lazy-blocks-pro.php`, with a trailing slash |

Three things read it:

| Where                            | What it loads                                                         |
| -------------------------------- | --------------------------------------------------------------------- |
| `init_options()`                 | every `classes/class-*.php` file the plugin needs                     |
| `include_control_dependencies()` | the Pro control classes, on `lzb/init` at priority 6                  |
| `Lazy_Blocks_Pro_Assets`         | the `.asset.php` files holding each script's dependencies and version |

## Usage

```php title="PHP"
// In a must-use plugin, so it is registered before Lazy Blocks Pro loads.
function my_lzb_pro_plugin_path( $plugin_path ) {
  return WP_CONTENT_DIR . '/vendor/lazy-blocks-pro/';
}

add_filter( 'lzb_pro/plugin_path', 'my_lzb_pro_plugin_path' );
```

The plugin builds its `require_once` calls from this value, so a path that does not exist is a fatal error rather than a missing feature. Keep the trailing slash: the code concatenates the value with `classes/class-assets.php` and similar relative paths.

`init_options()` runs while the plugin file itself is loading, before `plugins_loaded`, so a filter registered from a normal plugin or from a theme is too late for the first block of `require_once` calls. Only a must-use plugin runs early enough. The control dependencies loaded on `lzb/init` see the filter whenever it was added.

Changing the asset URL is a different filter, [lzb_pro/plugin_url](https://www.lazyblocks.com/docs/php-filters/lzb_pro-plugin_url/), and [Include Lazy Blocks within theme or plugin](https://www.lazyblocks.com/docs/examples/include-lazy-blocks-within-theme-or-plugin/) sets that one for you.
