Adding a new photo while editing an entry 500s: add-page-by-form's edit branch
reads existing frontmatter via `(array)$page->header()`, but Grav 2.0's
Grav\Common\Page\Header keeps data in a protected `items`, so the cast mangles
keys and `$original_frontmatter['photos']` is never set → array_merge(null,…)
TypeError. Fix: use Header::toArray() (clean keys, stdClass fallback) + guard the
per-field merge. Grav 2.0.7 does not change this — only the plugin fix does.
add-page-by-form is abandoned upstream (last release 2023-09) and its dir is
git-ignored/GPM-managed, so the fix is tracked as deploy/patches/*.patch and
re-applied after any GPM install/update:
- make apply-plugin-patches (local) — chained into install-plugins
- make remote-apply-plugin-patches-{test,prod} — piped over SSH into
`patch -p1 --forward`; chained into remote-install-plugins / remote-update-plugins
Content syncs don't touch user/plugins/, so the patch survives them; only a GPM
op wipes it (now auto-restored). Runbook + README document the step and a
verify check. Remove once the plugin is forked.
