Yarpp does not work with divi5

Issue Summary

When attempting to render YARPP (Yet Another Related Posts Plugin) results inside a Divi 5 Theme Builder template, the related posts query is not displayed, even though YARPP successfully returns related results when invoked inside post content. Technical Details

• Environment:
  • WordPress (latest stable)
  • Divi 5 (public alpha, Theme Builder templates)
  • YARPP 5.30.11
• Behavior:
  • When inserting [yarpp] inside post content, related posts render correctly.
  • When inserting [yarpp] or yarpp_related() inside a Divi 5 Theme Builder template (outside of the_content()), the output consistently shows “No related posts found.”
• Debugging performed:
  • Verified that yarpp_get_related() returns a boolean false instead of a WP_Query object when called from a Divi 5 template context.
  • Confirmed that YARPP’s SQL queries run successfully and that related posts exist in the database.
  • Verified that the Divi 5 template is active and executing by inserting test text/PHP in the same location.
  • This indicates the failure occurs not at the query level, but at the context detection layer.

Analysis

YARPP appears to depend on global state ($post and/or in_the_loop) to resolve the current post ID when building the related posts query. In Divi 5, Theme Builder templates render content through a React/PHP bridge rather than the legacy the_content pipeline, meaning these globals are not set as expected.

Thus:

• Inside post content → YARPP works (globals available).
• Inside Divi 5 templates → YARPP fails (globals unavailable, returns boolean).

Impact

• YARPP is currently not compatible with Divi 5 Theme Builder templates.
• Any attempt to display related posts outside of the_content() results in “No related posts found,” even if related posts exist.
• This breaks expected functionality for sites upgrading to Divi 5 that rely on YARPP in templates.

Suggested Resolution

• Update YARPP to accept an explicit post ID parameter (e.g., yarpp_get_related( $post_id )) without requiring global state.
• Ensure shortcode and function calls respect passed post_id values when Divi (or other block/template systems) do not expose global $post.
• Alternatively, Divi 5 could provide a compatibility shim that sets $post when rendering templates, but ideally YARPP should not rely solely on globals in modern WP contexts.
