Secure Custom Fields boosts content management with custom fields and options. It deactivates Advanced Custom Fields to prevent duplicate code errors.

== Description ==

Secure Custom Fields (SCF) extends WordPress’s capabilities, transforming it into a flexible content management tool. With SCF, managing custom data becomes straightforward and efficient.

**Easily create fields on demand.**
The SCF builder makes it easy to add fields to WordPress edit screens, whether you’re adding a new “ingredients” field to a recipe or designing complex metadata for a specialized site.

**Flexibility in placement.**
Fields can be applied throughout WordPress—posts, pages, users, taxonomy terms, media, comments, and even custom options pages—organizing your data how you want.

**Display seamlessly.**
Using SCF functions, you can display custom field data in your templates, making content integration easy for all levels of developers.

**A comprehensive content management solution.**
Beyond custom fields, SCF allows you to register new post types and taxonomies directly from the SCF interface, providing more control without needing additional plugins or custom code.

**Accessible and user-friendly design.**
The field interface aligns with WordPress’s native design, creating an experience that’s both accessible and easy for content creators to use.

Installing this plugin will deactivate plugins with matching function names/functionality, specifically Advanced Custom Fields, Advanced Custom Fields Pro, and the legacy Secure Custom Fields plugins, to avoid code errors (this is the same behavior as ACF Pro).

== Changelog ==
= 6.9.0 =
*Release Date 23rd June 2026*

*Hardening*

- Improved input validation when duplicating field groups, post types, and taxonomies, including ownership and type checks on the target.
- Restricted persistence of custom choices on checkbox, radio, and select fields to authorized users.
- Constrained the field update ability input schema to known properties.
- Sanitized flexible content layout labels and cleaned up orphaned row meta on layout removal.
- Hardened REST type field-group metadata exposure and oEmbed source formatting.
- Normalized non-scalar block binding attribute values.
- Required authentication and nonce verification before saving fields on WooCommerce orders.
- Preserved localization wrappers in PHP exports and corrected nav menu field ID output.

= 6.8.9 =
*Release Date 15th June 2026*

*Security*

- Hardened the escaping of wp_options LIKE queries used when loading option-page meta and during taxonomy term cleanup, switching to esc_like() so option-name prefixes are always matched as literals rather than as patterns.

*Fixes*

- The URL, text, textarea, and select-style fields no longer raise PHP errors when a non-scalar value (such as an array) is submitted; such input is now treated as invalid.

= 6.8.8 =
*Release Date 11th June 2026*

*Security*

- AJAX field handlers now validate that the request nonce was created for the expected field type, so a nonce minted for one field type can no longer be replayed against another field type's AJAX handler. The gallery field was also aligned with the typed nonce scheme used by all other AJAX fields.
- `acf_decrypt()` now treats malformed payloads as a decrypt failure and returns `false` instead of emitting PHP 8 warnings.

*Enhancements*

- `acf_inline_toolbar_editing_attrs()` now accepts a `return_array` argument that returns the attributes as an escaped array suitable for use with `wp_get_attachment_image()`.

*Fixes*

- `acf_form()` with `'post_id' => 'new_post'` and a `fields` list of field names no longer fatal errors when `acf_form_head()` runs before WordPress's main query is built.
- Multiple `acf_form()` calls wrapped inside a single outer form tag with one submit button no longer silently drop field values, `post_title`, or `post_content` from the non-last forms. A new `acf/form/meta_ttl` filter controls how long per-form metadata remains valid.
- Duplicating a V3 block with identical attributes no longer displays corrupted preview content in the duplicate.
- Switching between tabs containing WYSIWYG fields no longer leaves the admin menu pinned against a shorter page, which could lock page scroll.

= 6.8.7 =
*Release Date 8th June 2026*

*Fixes*

- SCF's Abilities API integration for its internal post types no longer triggers PHP warnings, notices, or a fatal error (500) on block editor and REST API requests when another active plugin builds the WordPress abilities registry earlier in the request; registration is skipped cleanly in that case and normal abilities behavior is otherwise unchanged.

= 6.8.6 =
*Release Date 27th May 2026*

*Security*

- Hardened the oEmbed field's AJAX preview handling by restricting provider discovery for visitors and users without content-authoring capability while preserving previews from WordPress's registered oEmbed providers.
- Hardened front-end `acf_form()` submission processing so the `post_title` and `post_content` form options are respected on save, and the save pipeline only accepts values for fields the rendered form exposed. A new `acf/form/allowed_field_keys` filter is available for sites that legitimately extend a form at runtime.

= 6.8.5 =
*Release Date 19th May 2026*

*Features*

Backports 6.8.1 feature work into SCF.
= 6.8.4 =
*Release Date 30th April 2026*

*Features*

- Backports 6.8.0 and 6.8.0.1 feature work into SCF.
- AI integration: SCF now integrates with the WordPress Abilities API, allowing external consumers, including AI tools, to manage field groups, post types, and taxonomies when explicitly enabled via the `enable_acf_ai` feature flag.
- Structured data: SCF can now generate JSON-LD structured data fields when explicitly enabled via the `enable_schema` feature flag.
- WP-CLI: Added `wp scf json` and backward-compatible `wp acf json` commands for importing, exporting, syncing, and checking the status of SCF JSON files.

- JSON Schemas: Added v1 schemas for supported field types and updated field group, post type, and taxonomy schemas.

*Enhancements*

- Blocks V3: The Open in Expanded Editor button text can now be customized via a new `acf.expandedEditorButtonText` block.json property.
- Blocks V3: Added an `acf/blocks/default_expanded_editor_button_text` PHP filter to customize the default Open in Expanded Editor button text.
- Blocks V3: The edit and Open in Expanded Editor buttons can now be hidden via a new `acf.expandedEditorButtons` block.json property.
- Blocks V3: Added a `blocks/expanded_editor_overlay_class` JavaScript filter for customizing the Expanded Editor modal overlay class.
- Blocks V3: The block form HTML is now preloaded alongside the preview, eliminating an extra AJAX call on mount.
- Blocks V3: Expanded Editor buttons are now hidden for V3 blocks that have no fields assigned.
- SCF inline script tags now use `wp_print_inline_script_tag()` for Content Security Policy (CSP) compliance and nonce support.

*Fixes*

- V3 blocks with WYSIWYG fields no longer enqueue TinyMCE editor assets on the frontend.
- V3 blocks with identical attributes and different InnerBlocks content no longer return cached output from the first block on the frontend.
- Flexible Content fields now properly clean up nested postmeta when a parent layout containing nested Flexible Content fields is deleted.
- The Expanded Editor Done button now stays disabled until the AJAX save completes, preventing data loss.
- Pressing Escape while the Expanded Editor is saving will no longer close the modal, preventing data loss.
