Changelog

1.1

  • Add new routes for taxonomies and terms.

    Taxonomies and terms have now been moved from the /posts/types/<type> namespace to global routes: /taxonomies, /taxonomies/<tax>, /taxonomies/<tax>/terms and /taxonomies/<tax>/terms/<term>

    Test coverage for taxonomy endpoints has also been increased to 100%.

    Deprecation warning: The /posts/types/<type>/taxonomies endpoint (and sub-endpoints with the same prefix) have been deprecated in favour of the new endpoints. These deprecated endpoints will now return a X-WP-DeprecatedFunction header indicating that the endpoint should not be used for new development, but will continue to work in the future.

    (props @kadamwhite, @rachelbaker, @rmccue, #198, #211)

  • Allow customizing the API resources prefix

    The API base (typically wp-json/) can now be customized to a different prefix using the json_url_prefix filter. Note that rewrites will need to be flushed manually after changing this.

    (props @ericandrewlewis, @rmccue, #104, #244, #278)

  • Give null as date for draft posts.

    Draft posts would previously return "0000-00-00 00:00:00" or "1970-01-01T00:00:00", as draft posts are not assigned a publish date. The API now returns null where a date is not available.

    Compatibility warning: Clients should be prepared to accept null as a value for date/time fields, and treat it as if no value is set.

    (props @rmccue, #229, #230)

  • Fix errors with excerpt.

    Posts without excerpts could previously return nonsense strings, excerpts from other posts, or cause internal PHP errors. Posts without excerpts will now always return an excerpt, typically automatically generated from the post content.

    The excerpt_raw field was added to the edit context on posts. This field contains the raw excerpt data saved for the post, including empty string values.

    (props @rmccue, #222, #226)

  • Only expose email for edit context.

    User email addresses are now only exposed for context=edit, which requires the edit_users permission (not required for the current user).

    The email address field will now return false instead of a string if the field is not exposed.

    (props @pkevan, @rmccue, #290, #296)

  • Correct password-protected post handling.

    Password-protected posts could previously be exposed to all users, however could also have broken behaviour with excerpts. Password-protected posts are now hidden to unauthenticated users, while content and excerpts are shown correctly for the edit context.

    (Note that hiding password-protected posts is intended to be a temporary measure, and will likely change in the future.)

    (props @rmccue, #286, #313)

  • Add documentation on authentication methods.

    Full documentation on authentication is now available. This documentation explains the difference between the various available authentication methods, and notes which should be used.

    (props @rmccue, #242)

  • Include new client JS from github.io

    The WP-API Javascript library is now loaded dynamically from wp-api.github.io to ensure it is always up-to-date.

    (props @tlovett1, #179, #240)

  • Don't allow setting the modification date on post creation/update.

    As it turns out, WP core doesn't allow us to set this, so this was previously a no-op anyway. Discovered during test coverage phase.

    (props @rachelbaker, @rmccue, #285, #288)

  • Check post parent correctly on insertion.

    Posts could previously be added with an invalid parent ID. These IDs are now checked to ensure the post exists.

    (props @rmccue, #228, #231)

  • Make sure the type is actually evaluated for json_prepare_${type} filter.

    This value was previously not interpolated correctly, due to the use of the single-quoted string type.

    (props @danielbachhuber, #266)

  • Return WP_Error instead of array of empty objects for a revisions permissions error.

    Previously, when trying to access post revisions without correct permissions, a JSON list of internal error objects would be returned. This has been corrected to return a standard API error instead.

    (props @rachelbaker, @tlovett1, #251, #276)

  • Flip user parameters check for insert/update.

    Previously, you could add a user without specifying username/password/email, but couldn't update a user without those parameters. The logic has been inverted here instead.

    (props @rmccue, #221, #289)

  • Add revision endpoints tests

    (props @danielbachhuber, @rachelbaker, @rmccue, #275, #277, #284, #279)

  • Add post endpoint testing

    Now at >54% coverage for the whole class, and >80% for the main methods. This figure will continue to rise over the next few releases.

    (props @rachelbaker, @rmccue, #99)

  • Separate helper functions into global namespace.

    WP_JSON_Server::get_timezone(), WP_JSON_Server::get_date_with_gmt(), WP_JSON_Server::get_avatar_url() and ``WP_JSON_Server::parse_date()` have all been moved into the global namespace to decouple them from the server class.

    Deprecation warning: These methods have been deprecated. The new json_get_timezone(), json_get_date_with_gmt(), json_get_avatar_url() and json_parse_date() methods should now be used instead.

    (props @rmccue, #185, #298)

  • Re-order Users and Media routes documentation based on CRUD order

    (props @rachelbaker, #214)

  • Update Post route documentation to provide more detail for data parameter

    (props @rachelbaker, #212)

  • Correct documentation typo ("inforcement" -> "enforcement").

    (props @ericandrewlewis, #236)

  • Coding Standards audit

    (props @DrewAPicture, #235)

  • Add comparison documentation.

    (props @rachelbaker, @rmccue, #217, #225)

  • json_url filter call should be passed $scheme

    (props @ericandrewlewis, #243)

  • Set class-jsonserializable.php file mode to 644.

    (props @jeremyfelt, #255)

  • Remove unneeded "which" in implementation doc.

    (props @JDGrimes, #254)

  • Fix a copy/paste error in schema doc.

    (props @JDGrimes, #253)

  • Correct reference link in example schema.

    (props @danielbachhuber, #258)

  • Add missing post formats to post schema documentation.

    (props @danielbachhuber, #260)

  • Ensure we always use "public" on public methods.

    (props @danielbachhuber, #268)

  • Ensure we don't cause a PHP error if a post does not have revisions.

    (props @rmccue, #227)

  • Add note to where upload_files cap comes from

    (props @pkevan, #282)

  • Add handling of sticky property when creating or editing posts.

    (props @rachelbaker, #218)

  • Update post route endpoint docs to include details on post_meta handling.

    (props @rachelbaker, #213)

  • Update main readme file to better describe the project.

    (props @rmccue, #303)

  • Fix --data-binary cURL option in documentation

    (props @Pezzab, @rachelbaker, @rmccue, #283, #304)

1.0

  • Add user endpoints.

    Creating, reading, updating and deleting users and their data is now possible by using the /users endpoints. /users/me can be used to determine the current user, and returns a 401 status for non-logged in users.

    Note that the format of post authors has changed, as it is now an embedded User entity. This should not break backwards compatibility.

    Custom post types gain this ability automatically.

    (props @tobych, @rmccue, #20, #146)

  • Add post meta endpoints.

    Creating, reading, updating and deleting post meta is now possible by using the /posts/<id>/meta endpoints. Post meta is now correctly embedded into Post entities.

    Meta can be updated via the Post entity (e.g. PUT to /posts/<id>) or via the entity itself at /posts/<id>/meta/<mid>. Meta deletion must be done via a DELETE request to the latter.

    Only non-protected and non-serialized meta can be accessed or manipulated via the API. This is not predicted to change in the future; clients wishing to access this data should consider alternative approaches.

    Custom post types do not currently gain this ability automatically.

    (props @attitude, @alisspers, @rachelbaker, @rmccue, @tlovett1, @tobych, @zedejose, #68, #168, #189, #207)

  • Add endpoint for deleting a single comment.

    Clients can now send a DELETE request to comment routes to delete the comment.

    Custom post types supporting comments will gain this ability automatically.

    (props @tlovett1, @rmccue, #178, #191)

  • Add endpoint for post revisions.

    Post revisions are now available at /posts/<id>/revisions, and are linked in the meta.links.version-history key of post entities.

    Custom post types supporting revisions will gain this ability automatically.

    (props @tlovett1, #193)

  • Respond to requests without depending on pretty permalink settings.

    For sites without pretty permalinks enabled, the API is now available from ?json_route=/. Clients should check for this via the autodiscovery methods (Link header or RSD).

    (props @rmccue, #69, #138)

  • Add register post type argument.

    Post types can now indicate their availability via the API using the show_in_json argument passed to register_post_type. This value defaults to the publicly_queryable argument (which itself defaults to the public argument).

    (props @iandunn, @rmccue, #145)

  • Remove basic authentication handler.

    This breaks backwards compatibility for clients using Basic authentication. Clients are encouraged to switch to using OAuth authentication. The Basic Authentication plugin can be installed for backwards compatibility and local development, however should not be used in production.

    (props @rmccue, #37, #152)

  • Require nonces for cookie-based authentication.

    This breaks backwards compatibility and requires any clients using cookie authentication to also send a nonce with the request. The built-in Javascript API automatically handles this.

    (props @rmccue, #177, #180)

  • Clean up deprecated methods/functions.

    Functions and methods previously deprecated in 0.8/0.9 have now been removed. Future deprecations will take place in the same manner as WordPress core.

    This breaks backwards compatibility, however these were marked as deprecated in previous releases.

    (props @rmccue, #187)

  • Only expose meta on 'edit' context as a temporary workaround.

    Privacy concerns around exposing meta to all users necessitate this change.

    This breaks backwards compatibility as post meta data is no longer available to all users. Clients wishing to access this data should authenticate and use the edit context.

    (props @iandunn, @rmccue, #135)

  • Add json_ensure_response function to ensure either a WP_JSON_ResponseInterface or a WP_Error object is returned.

    When extending the API, the json_ensure_response function can be used to ensure that any raw data returned is wrapped with a WP_JSON_Response object. This allows using get_status/get_data easily, however WP_Error must still be checked via is_wp_error.

    (props @rmccue, #151, #154)

  • Use version option to check on init if rewrite rules should be flushed.

    Rewrite rules on multisite are now flushed via an init hook, rather than switching to each site on activation.

    (props @rachelbaker, #149)

  • Fix typo in schema docs

    (props @codebykat, #132)

  • Add check for valid JSON data before using to avoid parameter overwrite.

    When passing data to an endpoint that accepts JSON data, the data will now be validated before passing to the endpoint.

    (props @rachelbaker, @rmccue, #133)

  • Add authentication property to site index.

    (props @rmccue, #131)

  • Move the test helper to a subdirectory.

    The plugin will now no longer prompt for updates due to the helper.

    (props @rmccue, #127)

  • Include post ID with json_prepare_meta filter.

    (props @rmccue, #137)

  • Corrected parameter names in x-form examples in docs.

    (props @rachelbaker, #134)

  • Pass WP_JSON_Server instance to json_serve_request.

    (props @alisspers, @rmccue, #61, #139)

  • Don't use deprecated function in WP_JSON_Posts::edit_post()

    (props @rachelbaker, #150)

  • Pass post ID to json_insert_post action during both insert and update.

    (props @cmmarslender, #148)

  • Add descriptions to taxonomy term data.

    (props @pushred, #111)

  • Ensure we handle raw data passed to the API.

    (props @tlovett1, @rmccue, #91, #155)

  • Remove unused prepare_author method from WP_JSON_Posts class.

    (props @rachelbaker, #165)

  • Add multiple post type support to get_posts method.

    (props @rmccue, #142, #163)

  • Return WP_Error in WP_JSON_Posts::get_comment for invalid comments.

    (props @tlovett1, #166, #171)

  • Update getting started documentation.

    (props @rmccue, #176)

  • Improve and clarify "array" input syntax documentation.

    (props @rmccue, #140, #175)

  • Update post routes documentation.

    (props @rmccue, #172, #174)

  • Add documentation for user endpoints.

    (props @rachelbaker, @rmccue, #158)

  • Add permalink settings step to Quick Setup instructions.

    (props @kadamwhite, #183)

  • Update taxonomy collection to return indexed array.

    (props @mattheu, #184)

  • Remove placeholder endpoints.

    (props @rmccue, #161, #192)

  • Fix issues with embedded attachments.

    Checks that the post supports attachment data before adding it, and ensures we don't embed entities many layers deep.

    (props @rmccue, #194)

  • Change post parent preparation context to embed.

    (props @rmccue, #195)

  • Change server meta links to reference the WP-API organization GitHub repo.

    (props @rachelbaker, #208)

  • Fix plugin tests

    (props @rmccue, #215)

  • Check for errors with invalid dates and remove duplicate date parsing methods.

    (props @rachelbaker, @rmccue, #216, #219)

0.9

  • Move from wp-json.php/ to wp-json/

    This breaks backwards compatibility and requires any clients to now use wp-json/, or preferably the new RSD/Link headers.

    (props @rmccue, @matrixik, #46, #96, #106)

  • Move filter registration out of CPT constructor. CPT subclasses now require you to call $myobject->register_filters(), in order to move global state out of the constructor.

    This breaks backwards compatibility and requires any subclassing to now call $myobject->register_filters()

    (props @rmccue, @thenbrent, #42, #126)

  • Introduce Response/ResponseInterface

    Endpoints that need to set headers or response codes should now return a WP_JSON_Response rather than using the server methods. WP_JSON_ResponseInterface may also be used for more flexible use of the response methods.

    Deprecation warning: Calling WP_JSON_Server::header, WP_JSON_Server::link_header and WP_JSON_Server::query_navigation_headers is now deprecated. This will be removed in 1.0.

    (props @rmccue, #33)

  • Change all semiCamelCase names to underscore_case.

    Deprecation warning: Any calls to semiCamelCase methods require any subclassing to update method references. This will be removed in 1.0.

    (props @osiux, #36, #82)

  • Add multisite compatibility. If the plugin is network activated, the plugin is now activated once-per-site, so wp-json/ is always site-local.

    (props @rachelbaker, #48, #49)

  • Add RSD and Link headers for discovery

    (props @rmccue, #40)

  • WP_JSON_Posts->prepare_author() now verifies the $user object is set.

    (props @rachelbaker, #51, #54)

  • Added unit testing framework. Currently only a smaller number of tests, but we plan to increase this significantly as soon as possible.

    (props @tierra, @osiux, #65, #76, #84)

  • Link collection filtering docs to URL formatting guide.

    (props @kadamwhite, #74)

  • Remove hardcoded /pages references from WP_JSON_Pages

    (props @rmccue, @thenbrent, #28, #78)

  • Fix compatibility with DateTime::createFromFormat on PHP 5.2

    (props @osiux, #52, #79)

  • Document that WP_JSON_CustomPostType::__construct() requires a param of type WP_JSON_ResponseHandler.

    (props @tlovett1, #88)

  • Add timezone parameter to WP_JSON_DateTime::createFromFormat()

    (props @royboy789, @rachelbaker, #85, #87)

  • Remove IXR references. IXR_Error is no longer accepted as a return value.

    This breaks backwards compatibility and requires anyone returning IXR_Error objects to now return WP_Error or WP_JSON_ResponseInterface objects.

    (props @rmccue, #50, #77)

  • Fix bugs with attaching featured images to posts:

    • WP_JSON_Media::attachThumbnail() should do nothing if $update is false without a post ID
    • The post ID must be fetched from the $post array.

    (props @Webbgaraget, #55)

  • Don't declare jsonSerialize on ResponseInterface

    (props @rmccue, #97)

  • Allow JSON post creation/update for WP_JSON_CustomPostType

    (props @tlovett1, #90, #108)

  • Return null if post doesn't have an excerpt

    (props @rachelbacker, #72)

  • Fix link to issue tracker in README

    (props @rmccue, @tobych, #125)

0.8

  • Add compatibility layer for JsonSerializable. You can now return arbitrary objects from endpoints and use the jsonSerialize() method to return the data to serialize instead of just using the properties of the object.

    (props @rmccue, #24)

  • Fix page parent links to use /pages

    (props @thenbrent, #27)

  • Remove redundant WP_JSON_Pages::type_archive_link() function

    (props @thenbrent, #29)

  • Removed unneeded executable bit on all files

    (props @tierra, #31)

  • Don't include the featured_image property for post types that don't support thumbnails

    (props @phh, #43)

  • Use wp_json_server_before_serve instead of plugins_loaded in the Extending documentation for plugins

    (props @phh, #43)

  • Parse the avatar URL from the get_avatar() function in core, allowing custom avatar implementations

    (props @rachelbaker, #47, #35)

  • Ensure that the author is set if passed

    (props @kuchenundkakao, #44)

  • Clarify the usage of WP_JSON_CustomPostType in plugins

    (props @rmccue, #45)

  • Ensure JSON disabled error messages are translated

    (props @rmccue, #38)

  • Remove extra "Link: " from link headers

    (props @jmusal, #56, #30)

  • Remove redundant get_avatar method in WP_JSON_Posts

    (props @rachelbaker, #35)

  • Rename WP_JSON_Server::get_avatar() to WP_JSON_Server::get_avatar_url()

    (props @rachelbaker, #35)

View all changes

0.7

  • The response handler object is now passed into the endpoint objects via the constructor, allowing you to avoid excess global state where possible. It's recommended to use this where possible rather than the global object.

    (props @rmccue, #2)

  • Fix undefined variables and indices (props @pippinsplugins, #5)

  • Correct call to deactivation hook (props @ericpedia, #9)

  • Check metadata access correctly rather than always hiding for users without the edit_post_meta capability (props @kokarn, #10)

  • Return all term metadata, rather than just the last one (props @afurculita, #13)

  • Access post metadata from cache where possible - Note, this is a backwards compatibility break, as the format of the metadata has changed. This may change again in the near future, so don't rely on it until 1.0. (props @afurculita, #14)

  • Add term_link to prepare_term (props @afurculita, #15)

  • Fix hardcoded /pages references in WP_JSON_CustomPostType (props @thenbrent, #26)

  • Sanitize headers for newlines (props @kokarn, #7)

  • Register rewrite rules during plugin activation (props @pippinsplugins, #17)

0.6

  • Huge documentation update - Guides on getting started and extending the API are now available for your perusal
  • Add generic CPT class - Plugins are now encouraged to extend WP_JSON_CustomPostType and get free hooking for common actions. This removes most of the boilerplate that you needed to write for new CPT-based routes and endpoints (#380)
  • Use defined filter priorities for endpoint registration - It's now easier to inject your own endpoints at a defined point
  • Update the schema - Now includes documentation on the Media entity, plus more (#264)
  • Add better taxonomy support - You can now query for taxonomies and terms directly. The routes here might seem strange (/posts/types/post/taxonomies/category for example), but the intention is to future-proof them as much as possible(#275)
  • Ensure the JSON URL is relative to the home URL (#375)
  • Check all date formats for If-Unmodified-Since (#378)
  • Register the correct URL for the JS library (#376)
  • Correct the usage of meta links (#379)
  • Add filters for post type and post status data (#380)
  • Separate parent post and parent comment relation (#330()

View all changes

0.5

  • Add support for media - This has been a long time coming, and it's finally at a point where I'm happy to push it out. Good luck. (#272)

  • Separate the post-related endpoints - Post-related endpoints are now located in the WP_JSON_Posts class. When implementing custom post type support, it's recommended to subclass this.

    The various types are now also only registered via hooks, rather than directly in the server class, which should make it easier to override them as well (#348)

  • Add page support - This is a good base if you're looking to create your own custom post type support (#271)

  • Switch from fields to context - Rather than passing in a list of fields that you want, you can now pass in a context (usually view or edit) (#328).

  • Always send headers via the server handler - Endpoints are now completely separate from the request, so the server class can now be used for non-HTTP/JSON handlers if needed (#293)

  • Use better error codes for disabled features (#338)

  • Send X-WP-Total and X-WP-TotalPages headers for information on post/pagination counts (#266)

View all changes

0.4

  • Add Backbone-based models and collections - These are available to your code by declaring a dependency on wp-api (#270)
  • Check json_route before using it (#336)
  • Conditionally load classes (#337)
  • Add additional test helper plugin - Provides code coverage as needed to the API client tests. Currently unused. (#269)
  • Move json_url() and get_json_url() to plugin.php - This allows using both outside of the API itself (#343)
  • getPost(0) now returns an error rather than the latest post (#344)

View all changes

0.3

  • Add initial comment endpoints to get comments for a post, and get a single comment (#320)
  • Return a Post entity when updating a post, rather than wrapping it with useless text (#329)
  • Allow filtering the output as well as input. You can now use the json_dispatch_args filter for input as well as the json_serve_request filter for output to serve up alternative formats (e.g. MsgPack, XML (if you're insane))
  • Include a profile link in the index, to indicate the JSON Schema that the API conforms to. In the future, this will be versioned.

0.2

  • Allow all public query vars to be passed to WP Query - Some private query vars can also be passed in, and all can if the user has edit_posts permissions (#311)
  • Pagination can now be handled by using the page argument without messing with WP Query syntax (#266)
  • The index now generates links for non-variable routes (#268)
  • Editing a post now supports the If-Unmodified-Since header. Pass this in to avoid conflicting edits (#294)
  • Post types and post statuses now have endpoints to access their data (#268)

View all changes

0.1.2

  • Disable media handling to avoid fatal error (#298)

0.1.1

  • No changes, process error

0.1

  • Enable the code to be used via the plugin architecture (now uses rewrite rules if running in this mode)
  • Design documents are now functionally complete for the current codebase (#264)
  • Add basic writing support (#265)
  • Filter fields by default - Unfiltered results are available via their corresponding *_raw key, which is only available to users with edit_posts (#290)
  • Use correct timezones for manual offsets (GMT+10, e.g.) (#279)
  • Allow permanently deleting posts (#292)

View all changes

0.0.4

  • Hyperlinks now available in most constructs under the 'meta' key. At the moment, the only thing under this key is 'links', but more will come eventually. (Try browsing with a browser tool like JSONView; you should be able to view all content just by clicking the links.)
  • Accessing / now gives an index which briefly describes the API and gives links to more (also added the HIDDEN_ENDPOINT constant to hide from this).
  • Post collections now contain a summary of the post, with the full post available via the single post call. (prepare_post() has fields split into post and post-extended)
  • Post entities have dropped post_ prefixes, and custom_fields has changed to post_meta.
  • Now supports JSONP callback via the _jsonp argument. This can be disabled separately to the API itself, as it's only needed for cross-origin requests.
  • Internal: No longer extends the XMLRPC class. All relevant pieces have been copied over. Further work still needs to be done on this, but it's a start.

0.0.3:

  • Now accepts JSON bodies if an endpoint is marked with ACCEPT_JSON
