Filters

`vmfa_export_dir`

Change the directory where export ZIP files are stored. Defaults to wp-content/uploads/vmfa-exports.

Parameters

Parameter	Type	Description
`$export_dir`	`string`	Absolute path to the export directory

Example — store exports outside the web root

add_filter( 'vmfa_export_dir', function ( string $dir ): string {
    return '/var/private/media-exports';
} );

Example — use a site-specific subdirectory on multisite

add_filter( 'vmfa_export_dir', function ( string $dir ): string {
    $upload = wp_upload_dir();
    return $upload['basedir'] . '/vmfa-exports/' . get_current_blog_id();
} );

Note: The directory is created automatically if it does not exist. An .htaccess and index.php are added to prevent direct browsing.

`vmfa_export_manifest_columns`

Customise the CSV manifest column headers. The row data is built in ManifestService::build_row() — if you add columns here you also need to filter the row data.

Parameters

Parameter	Type	Description
`$columns`	`array<string>`	Default column headers

Default columns

ID, filename, url, alt_text, caption, description,
mime_type, file_size_bytes, width, height, date_uploaded, folder_path

Example — remove dimensions, add a custom column

add_filter( 'vmfa_export_manifest_columns', function ( array $columns ): array {
    // Remove width and height.
    $columns = array_diff( $columns, [ 'width', 'height' ] );

    // Add a custom column.
    $columns[] = 'photographer';

    return array_values( $columns );
} );

REST API

All endpoints require the upload_files capability. Authenticate with a nonce (X-WP-Nonce header) or an application password.

Base URL: /wp-json/vmfa-folder-exporter/v1

Start an export

POST /exports

Parameter	Type	Default	Description
`folder_id`	`integer`	(required)	Folder term ID
`include_children`	`boolean`	`true`	Include subfolders
`include_manifest`	`boolean`	`true`	Add CSV manifest to ZIP

Example

curl -X POST \
  "https://example.com/wp-json/vmfa-folder-exporter/v1/exports" \
