[Credits](https://github.com/MickeyKay/better-font-awesome-library#credits) - -## Introduction ## -The Better Font Awesome Library allows you to automatically integrate the latest available version of [Font Awesome](http://fontawesome.io/) into your WordPress project, along with accompanying CSS, shortcode, and TinyMCE icon shortcode generator. Furthermore, it generates all the data you need to create new functionality of your own. - -## Features ## -* Automatically fetches the most recent available version of Font Awesome, meaning you no longer need to manually update the version included in your theme/plugin. -* Generates an easy-to-use [PHP object](#the-better-font-awesome-library-object) that contains all relevant info for the version of Font Awesome you're using, including: version, stylesheet URL, array of available icons, and prefix used (`icon` or `fa`). -* CDN speeds - Font Awesome CSS is pulled from the super-fast and reliable [jsDelivr CDN](http://www.jsdelivr.com/#!fontawesome). -* Includes a TinyMCE drop-down shortcode generator. -* Includes a local copy of Font Awesome to use as a fallback in case the remote fetch fails (or you can specify your own with the [`bfa_fallback_directory_path`](https://github.com/MickeyKay/better-font-awesome-library#bfa_fallback_directory_path) filter). -* Utilizes transients to optimize for speed and performance. - -## Installation ## -The Better Font Awesome Library contains a [Git submodule](http://git-scm.com/book/en/Git-Tools-Submodules) which will require you to recursively clone this repo: -``` -git clone --recursive https://github.com/MickeyKay/better-font-awesome-library.git -``` - -Alternately, if you've already cloned the repo and need to add the submodules, you can run the following command: -``` -// Initialize and update all submodules. -git submodule update --init --recursive -``` - -## Usage ## -1. Copy the /better-font-awesome-library folder into your project. - -2. Add the following code to your main plugin file or your theme's functions.php file. - ```php - add_action( 'init', 'my_prefix_load_bfa' ); - /** - * Initialize the Better Font Awesome Library. - * - * (see usage notes below on proper hook priority) - */ - function my_prefix_load_bfa() { - - // Include the main library file. Make sure to modify the path to match your directory structure. - require_once ( dirname( __FILE__ ) . '/better-font-awesome-library/better-font-awesome-library.php' ); - - // Set the library initialization args (defaults shown). - $args = array( - 'version' => 'latest', - 'minified' => true, - 'remove_existing_fa' => false, - 'load_styles' => true, - 'load_admin_styles' => true, - 'load_shortcode' => true, - 'load_tinymce_plugin' => true, - ); - - // Initialize the Better Font Awesome Library. - Better_Font_Awesome_Library::get_instance( $args ); - } -``` - -3. If desired, use the [Better Font Awesome Library object](#the-better-font-awesome-library-object) to manually include Font Awesome CSS, output lists of available icons, create your own shortcodes, and much more. - -#### Usage Notes #### -The Better Font Awesome Library is designed to work in conjunction with the [Better Font Awesome](https://wordpress.org/plugins/better-font-awesome/) WordPress plugin. The plugin initializes this library (with its initialization args) on the `init` hook, priority `5`. When using the Better Font Awesome Library in your project, you have two options: - -1. Initialize later, to ensure that any Better Font Awesome plugin settings override yours (this is the default behavior, shown above by initializing the library on the `init` hook with default priority `10`. -1. Initialize earlier, to "take over" and prevent Better Font Awesome settings from having an effect. - -## Initialization Parameters ($args) ## -The following arguments can be used to initialize the library using `Better_Font_Awesome_Library::get_instance( $args )`: - -#### $args['version'] #### -(string) Which version of Font Awesome you want to use. -* `'latest'` (default) - always use the latest available version. -* `'3.2.1'` - any existing Font Awesome version number. - -#### $args['minified'] #### -(boolean) Use minified Font Awesome CSS. -* `true` (default) - uses minifed CSS. -* `false` - uses unminified CSS. - -#### $args['remove_existing_fa'] #### -(boolean) Attempts to remove existing Font Awesome styles and shortcodes. This can be useful to prevent conflicts with other themes/plugins, but is no guarantee. -* `true` -* `false` (default) - -#### $args['load_styles'] #### -(boolean) Automatically loads Font Awesome CSS on the **front-end** of your site using `wp_enqueue_scripts()`. -* `true` (default) -* `false` - use this if you don't want to load the Font Awesome CSS on the front-end, or wish to do it yourself. - -#### $args['load_admin_styles'] #### -(boolean) Automatically loads Font Awesome CSS on the **admin** of your site using `admin_enqueue_scripts()`. -* `true` (default) -* `false` - use this if you don't want to load the Font Awesome CSS in the admin, or wish to do it yourself. - -#### $args['load_shortcode'] #### -(boolean) Loads the included `[icon]` [shortcode](https://github.com/MickeyKay/better-font-awesome-library#shortcode). -* `true` (default) -* `false` - -#### load_tinymce_plugin #### -(boolean) Loads a TinyMCE drop-down list of available icons (based on the active Font Awesome version), which generates an `[icon]` shortcode. -* `true` (default) -* `false` - -## Shortcode ## -If either the `$args['load_shortcode']` or `$args['load_tinymce_plugin']` initialization arg is set to `true`, then the Better Font Awesome Library will include an icon shortcode that can be used as follows: -``` -[icon name="star" class="2x spin" unprefixed_class="my-custom-class"] -``` - -**name** -The unprefixed icon name (e.g. star). The version-specific prefix will be automatically prepended. - -**class** -Unprefixed [Font Awesome icon classes](http://fortawesome.github.io/Font-Awesome/examples/). The version-specific prefix will be automatically prepended to each class. - -**unprefixed_class** -Any additional classes that you wish to remain unprefixed (e.g. my-custom-class). - -#### Shortcode Output #### -The example shortcode above would output the following depending on which version of Font Awesome you've selected: - -**Version 4+** -``` - -``` -**Version 3** -``` - -``` - -## The Better Font Awesome Library Object ## -The Better Font Awesome Library object can be accessed with the following code: -`Better_Font_Awesome_Library::get_instance();` - -The object has the following public methods: -#### get_version() #### -(string) Returns the active version of Font Awesome being used. - -#### get_stylesheet_url() #### -(string) Returns the active Font Awesome stylesheet URL. - -#### get_icons() #### -(array) Returns an associative array of icon hex values (index, e.g. \f000) and unprefixed icon names (values, e.g. rocket) for all available icons in the active Font Awesome version. - -#### get_prefix() #### -(string) Returns the version-dependent prefix ('fa' or 'icon') that is used in the icons' CSS classes. - -#### get_api_data() #### -(object) Returns version data for the remote jsDelivr CDN (uses [jsDelivr API](https://github.com/jsdelivr/api)). Includes all available versions and latest version. - -#### get_errors() #### -(array) Returns all library errors, including API and CDN fetch failures. - -#### Example: #### -```php -// Initialize the library with custom args. -Better_Font_Awesome_Library::get_instance( $args ); - -// Get the active Better Font Awesome Library Object. -$my_bfa = Better_Font_Awesome_Library::get_instance(); - -// Get info on the Better Font Awesome Library object. -$version = $my_bfa->get_version(); -$stylesheet_url = $my_bfa->get_stylesheet_url(); -$prefix = $my_bfa->get_prefix(); -$icons = $my_bfa->get_icons(); - -// Output all available icons. -foreach ( $icons as $icon ) { - echo $icon . '
'; -} -``` - -## Filters ## -The Better Font Awesome Library applies the following filters: - -#### bfa_init_args #### -Applied to the initialization arguments after they have been parsed with default args, but before they are used to fetch any Font Awesome data. - -**Parameters** - -* `$init_args` (array) - -#### bfa_wp_remote_get_args #### -Applied to arguments passed to all `wp_remote_get()` calls (useful for adjusting the timeout if needed). - -**Parameters** - -* `$wp_remote_get_args` (array) - -#### bfa_fallback_directory_path #### -Applied to the fallback directory path before setting up any fallback CSS info. Can be used to specify an alternate fallback directory to replace the default fallback directory. - -*The path must be to a local, non-remote, directory.* - -**Parameters** - -* `$path` (string) - -#### bfa_api_transient_expiration #### -Applied to the API (version information) transient [expiration](http://codex.wordpress.org/Transients_API#Using_Transients).
