README 文档
README
JSON Schema bundle for Advanced Custom Fields JSON exports — field groups (acf.json), Custom Post Types (<cpt>.json), Taxonomies (<tax>.json), and ACF Blocks (block.json).
Target: ACF Pro 6.8.x. Free edition partially supported (field-group + field-type schemas only).
Generated against: ACF Pro 6.8.2 · WPML 4.9.4 · ACFML 2.2.4 — the live install the canonical schemas were curated and snapshot-tested against.
What this is
Comprehensive JSON Schema (draft 2020-12) coverage for every JSON file the ACF Pro Admin Sync UI emits. Schemas are hand-curated against a live WP + ACF Pro + WPML install — the generator (bin/acf-schema-gen) reproduces the canonical baseline, and a snapshot test asserts byte-equality on every CI run. WPML/ACFML keys (e.g. acfml_field_group_mode, wpml_cf_preferences) are optional, so plain ACF (non-WPML) exports validate too.
Use case: lint your project's ACF JSON files in CI. Catch typos, type drift, and shape regressions before they ship to production.
Install
composer require --dev parisek/acf-json-schema
Point your Ajv-based JSON validator at vendor/parisek/acf-json-schema/schemas/:
import path from "node:path"; import { createRequire } from "node:module"; const require = createRequire(import.meta.url); const pkgPath = require.resolve("parisek/acf-json-schema/composer.json"); const SCHEMAS_ROOT = path.join(path.dirname(pkgPath), "schemas");
Load acf.schema.json, block.schema.json, cpt.schema.json, or taxonomy.schema.json from SCHEMAS_ROOT, register the refs/ directory, and validate your project's ACF JSON files against them.
Bundled schemas
| File | Validates |
|---|---|
schemas/acf.schema.json |
ACF Field Group JSON — discriminates on type to per-field-type refs |
schemas/block.schema.json |
ACF Block JSON (block.json with acf section) |
schemas/cpt.schema.json |
ACF Custom Post Type JSON (Pro 6.2+ JSON-Sync) |
schemas/taxonomy.schema.json |
ACF Taxonomy JSON (Pro 6.2+ JSON-Sync) |
schemas/refs/field-<36 types>.schema.json |
Per-field-type closed-shape constraints (35 stable + icon_picker new in 6.8) |
schemas/refs/{field,icon,location-rule,permalink-rewrite}.schema.json |
Shared utility refs |
(_meta.json carries generator provenance — ACF version, timestamp — and is intentionally not part of the canonical schemas.)
Linting your project's ACF JSON (PHP)
composer require --dev parisek/acf-json-schema vendor/bin/acf-lint --strict path/to/templates path/to/blocks
acf-lint walks the given files/dirs, dispatches each JSON to the right bundled schema (block / acf / cpt / taxonomy), and reports findings. Files of an unrecognized shape are skipped.
| Flag | Effect |
|---|---|
--strict |
Exit non-zero on any finding (CI gate). |
--fix |
Bump stale/missing modified timestamps. |
--wpml |
Require WPML/ACFML translation keys to be present: acfml_field_group_mode on each field group and wpml_cf_preferences on every value-holding field (recurses into repeater/group/flexible-content; tab/message/accordion are exempt). Opt-in — the schemas keep these keys optional so non-WPML projects are unaffected. |
For maintainers
Regenerate / verify schemas against a live WP+ACF Pro install:
ddev exec "php vendor/bin/acf-schema-gen --wp-root /var/www/html --output /tmp/acf-schemas-out/" diff -r /tmp/acf-schemas-out/ vendor/parisek/acf-json-schema/schemas/
