WebflowMapper::build_images │ private │ WC 1.0

Build the unified images array (product gallery + SKU images, deduped by URL).

The importer requires every image referenced from a variation to also appear in this top-level array — that's how the original_id => attachment mapping is populated. We assign stable original_ids here (preferring Webflow's fileId, falling back to a URL hash) so SKU references resolve cleanly later.

Method of the class: WebflowMapper{}

No Hooks.

Returns

array<int,array{original_id:string,src:string,alt:?string,is_featured:bool}>.

Usage

// private - for code of main (parent) class only
$result = $this->build_images( $field_data, $skus ): array;
$field_data(object) (required)
Product fieldData.
$skus(array<int,object>) (required)
SKUs array.
