Problem: The client needs to duplicate approximately 15,000 products to all languages on their WooCommerce site but finds the translation management page limiting as it only allows duplicating 100 products at a time. Solution: We recommend using the WPML hooks
wpml_make_post_duplicates
and
wpml_admin_make_post_duplicates
for bulk duplication of products. These hooks can help automate the process. However, implementing custom code using these hooks is outside our support scope. We advise testing the hooks on a staging or sandbox site first to ensure they meet your needs. For more details on these hooks, please visit the WPML Hooks Reference page at WPML Hooks Reference.
If this solution does not apply to your case, or if it seems outdated, we highly recommend checking related known issues at WPML Known Issues, verifying the version of the permanent fix, and confirming that you have installed the latest versions of themes and plugins. Should you need further assistance, please do not hesitate to open a new support ticket at WPML Support Forum.
