## Description

CMB2 is a developer's toolkit for building metaboxes, custom fields, and forms for WordPress that will blow your mind.

**[Download plugin on wordpress.org](http://wordpress.org/plugins/cmb2/)**

CMB2 is a complete rewrite of [Custom Metaboxes and Fields for WordPress](https://github.com/WebDevStudios/Custom-Metaboxes-and-Fields-for-WordPress). To get started, please follow the examples in the included `example-functions.php` file and have a look at the [basic usage instructions](https://github.com/WebDevStudios/CMB2/wiki/Basic-Usage).

You can see a list of available field types [here](https://github.com/WebDevStudios/CMB2/wiki/Field-Types#types).

## Features:

* Create metaboxes to be used on post edit screens.
* [Create forms to be used on an options pages](https://github.com/WebDevStudios/CMB2/wiki/Using-CMB-to-create-an-Admin-Theme-Options-Page).
* Create forms to handle user meta and display them on user profile add/edit pages.
* [Flexible API that allows you to use CMB forms almost anywhere, even on the front-end](https://github.com/WebDevStudios/CMB2/wiki/Bringing-Metaboxes-to-the-Front-end).
* [Several field types are included](https://github.com/WebDevStudios/CMB2/wiki/Field-Types).
* [Custom API hook that allows you to create your own field types](https://github.com/WebDevStudios/CMB2/wiki/Adding-your-own-field-types).
* There are numerous hooks and filters, allowing you to modify many aspects of the library (without editing it directly).
* Repeatable fields for most field types are supported, as well as repeatable field groups.
* CMB2 is safe to bundle with any project. It will only load the newest version in the system.

## Translation
* Thanks to many in the CMB2 community and to our friends at [wp-translations.org](http://wp-translations.org/project/cmb2/), we have a good start on several translations for CMB2. Please feel free to [work with wp-translations.org](http://wp-translations.org/project/cmb2/) to provide even more!

4. Profit.

If including the library in your plugin or theme:

1. Place the CMB2 directory inside of your theme or plugin.
2. Copy (and rename if desired) `example-functions.php` into a folder *above* the CMB2 directory OR copy the entirety of its contents to your theme's `functions.php` file.
2. Edit to only include the fields you need and rename the functions (CMB2 directory should be left unedited in order to easily update the library).
4. Profit.

## Most Recent Changes

### 2.1.2

#### Bug Fixes

* Fixes back-compatibility issue when adding fields array to the metabox registration. ([#472](https://github.com/WebDevStudios/CMB2/pull/472))

### 2.1.1

#### Enhancements

* Make all CMB2::save_fields arguments optional to fall-back to `$_POST` data. Props [JPry](https://github.com/JPry).
* New filter, `cmb2_non_repeatable_fields` for adding additional fields to the blacklist of repeatable field-types. Props [JPry](https://github.com/JPry) ([#430](https://github.com/WebDevStudios/CMB2/pull/430)).
* New recommended hoook for adding metaboxes, `cmb2_admin_init`. Most metabox registration only needs to happen if in wp-admin, so there is no reason to register them when loading the front-end (and increase the memory usage). `cmb2_init` still exists to register metaboxes that will be used on the front-end or used on both the front and back-end. Instances of `cmb2_init` in example-functions.php have been switched to `cmb2_admin_init`.
* Add `'render_row_cb'` field parameter for overriding the field render method.
* Add `'label_cb'` field parameter for overriding the field label render method.
* Allow `CMB2_Types::checkbox()` method to be more flexible for extending by taking an args array and an `$is_checked` second argument.
* More thorough unit tests. Props [pglewis](https://github.com/pglewis), ([#447](https://github.com/WebDevStudios/CMB2/pull/447),[#448](https://github.com/WebDevStudios/CMB2/pull/448)).
* Update `CMB2_Utils::image_id_from_url` to be more reliable. Props [wpscholar](https://github.com/wpscholar), ([#453](https://github.com/WebDevStudios/CMB2/pull/453)).
* `cmb2_get_option` now takes a default fallback value as a third parameter.

#### Bug Fixes

* Address issue where `'file'` and `'file_list'` field results were getting mixed. Props [augustuswm](https://github.com/augustuswm) ([#382](https://github.com/WebDevStudios/CMB2/pull/382), [#250](https://github.com/WebDevStudios/CMB2/pull/250), [#296](https://github.com/WebDevStudios/CMB2/pull/296)).

* Fixes issue with `'file_list'` fields not saving properly when in repeatable groups display. Props [jamiechong](https://github.com/jamiechong) ([#433](https://github.com/WebDevStudios/CMB2/pull/433),[#187](https://github.com/WebDevStudios/CMB2/pull/187)).
