In your constructor, pass an optional array 19 * of arguments to parent::init() to configure your widget. The config array 20 * supports the following values: 21 * - 'slug' A unique identifier for your extension. This value will be used 22 * to build URLs, so make it URL-safe. 23 * - 'name' A translatable name for your extension. This value is used to 24 * populate the navigation tab, as well as the default titles for admin/ 25 * edit/create tabs. 26 * - 'visibility' Set to 'public' (default) for your extension (the main tab 27 * as well as the widget) to be available to anyone who can access the 28 * group, 'private' otherwise. 29 * - 'nav_item_position' An integer explaining where the nav item should 30 * appear in the tab list. 31 * - 'enable_nav_item' Set to true for your extension's main tab to be 32 * available to anyone who can access the group. 33 * - 'nav_item_name' The translatable text you want to appear in the nav tab. 34 * Defaults to the value of 'name'. 35 * - 'display_hook' The WordPress action that the widget_display() method is 36 * hooked to. 37 * - 'template_file' The template file that will be used to load the content 38 * of your main extension tab. Defaults to 'groups/single/plugins.php'. 39 * - 'screens' A multi-dimensional array, described below. 40 * - 'access' Which users can visit the plugin's tab. 41 * - 'show_tab' Which users can see the plugin's navigation tab. 42 * 43 * BP_Group_Extension uses the concept of "settings screens". There are three 44 * contexts for settings screens: 45 * - 'create', which inserts a new step into the group creation process 46 * - 'edit', which adds a tab for your extension into the Admin section of 47 * a group 48 * - 'admin', which adds a metabox to the Groups administration panel in the 49 * WordPress Dashboard 50 * Each of these settings screens is populated by a pair of methods: one that 51 * creates the markup for the screen, and one that processes form data 52 * submitted from the screen. If your plugin needs screens in all three 53 * contexts, and if the markup and form processing logic will be the same in 54 * each case, you can define two methods to handle all of the screens: 55 * function settings_screen() {} 56 * function settings_screen_save() {} 57 * If one or more of your settings screen needs separate logic, you may define 58 * context-specific methods, for example: 59 * function edit_screen() {} 60 * function edit_screen_save() {} 61 * BP_Group_Extension will use the more specific methods if they are available. 62 * 63 * You can further customize the settings screens (tab names, etc) by passing 64 * an optional 'screens' parameter to the init array. The format is as follows: 65 * 'screens' => array( 66 * 'create' => array( 67 * 'slug' => 'foo', 68 * 'name' => 'Foo', 69 * 'position' => 55, 70 * 'screen_callback' => 'my_create_screen_callback', 71 * 'screen_save_callback' => 'my_create_screen_save_callback', 72 * ), 73 * 'edit' => array( // ... 74 * ), 75 * Only provide those arguments that you actually want to change from the 76 * default configuration. BP_Group_Extension will do the rest. 77 * 78 * Note that the 'edit' screen accepts an additional parameter: 'submit_text', 79 * which defines the text of the Submit button automatically added to the Edit 80 * screen of the extension (defaults to 'Save Changes'). Also, the 'admin' 81 * screen accepts two additional parameters: 'metabox_priority' and 82 * 'metabox_context'. See the docs for add_meta_box() for more details on these 83 * arguments. 84 * 85 * Prior to BuddyPress 1.7, group extension configurations were set slightly 86 * differently. The legacy method is still supported, though deprecated. 87 * 88 * @since 1.1.0 89 */ 90 class BP_Group_Extension { 91 92 /** Public ************************************************************/ 93 94 /** 95 * Information about this extension's screens. 96 * 97 * @since 1.8.0 98 * @var array 99 */ 100 public $screens = array(); 101 102 /** 103 * The name of the extending class. 104 * 105 * @since 1.8.0 106 * @var string 107 */ 108 public $class_name = ''; 109 110 /** 111 * A ReflectionClass object of the current extension. 112 * 113 * @since 1.8.0 114 * @var ReflectionClass 115 */ 116 public $class_reflection = null; 117 118 /** 119 * Parsed configuration parameters for the extension. 120 * 121 * @since 1.8.0 122 * @var array 123 */ 124 public $params = array(); 125 126 /** 127 * Raw config params, as passed by the extending class. 128 * 129 * @since 2.1.0 130 * @var array 131 */ 132 public $params_raw = array(); 133 134 /** 135 * The ID of the current group. 136 * 137 * @since 1.8.0 138 * @var int 139 */ 140 public $group_id = 0; 141 142 /** 143 * The slug of the current extension. 144 * 145 * @since 1.1.0 146 * @var string 147 */ 148 public $slug = ''; 149 150 /** 151 * The translatable name of the current extension. 152 * 153 * @since 1.1.0 154 * @var string 155 */ 156 public $name = ''; 157 158 /** 159 * The visibility of the extension tab.
