Duplicate Post Exclusion for Query Loop Block

שאלות נפוצות

How do I prevent duplicate posts in Query Loop blocks?

Edit each Query Loop block and enable Make posts unique on page in the block sidebar. On the front end, every enabled loop excludes the posts already shown by the loops above it, so each post appears only once on the page.

Do I need a separate block?

No. The plugin extends the native core/query block only.

Will it slow down my site?

No. The plugin adds no extra database queries. It only adjusts the post__not_in argument of the queries your Query Loops already run, using a per-request in-memory registry.

Does this affect the editor preview?

No. Cross-loop exclusion runs on the front end only. The editor preview uses the REST API and does not simulate exclusion between multiple loops on the same page.

Do Query Loops without the option participate?

No. Only loops with Make posts unique on page enabled register and exclude posts.

Does this work with Advanced Query Loop or other Query Loop variations?

Yes. Variations register on the native core/query block. This plugin extends the same block and uses official render hooks, so it works alongside extensions like Advanced Query Loop.

Does it work with "Inherit query from template"?

Partially. A Query Loop set to inherit the template query renders from the global query and does not pass through the query_loop_block_query_vars filter. Such an inherited loop still registers the posts it shows, so a later custom loop will exclude them. However, exclusion is not applied to the inherited loop itself (it will not hide posts shown by an earlier loop). Full support for inherited queries is planned for a future release.
