When a local 105 * avatar is not found, Gravatar is queried. To disable Gravatar fallbacks 106 * locally: 107 * add_filter( 'bp_core_fetch_avatar_no_grav', '__return_true' ); 108 * 109 * @since 1.1.0 110 * @since 2.4.0 Added 'extra_attr', 'scheme', 'rating' and 'force_default' for $args. 111 * These are inherited from WordPress 4.2.0. See {@link get_avatar()}. 112 * 113 * @param array|string $args { 114 * An array of arguments. All arguments are technically optional; some 115 * will, if not provided, be auto-detected by bp_core_fetch_avatar(). This 116 * auto-detection is described more below, when discussing specific 117 * arguments. 118 * 119 * @type int|bool $item_id The numeric ID of the item for which you're requesting 120 * an avatar (eg, a user ID). If no 'item_id' is present, 121 * the function attempts to infer an ID from the 'object' + the 122 * current context: if 'object' is 'user' and the current page is a 123 * user page, 'item_id' will default to the displayed user ID; if 124 * 'group' and on a group page, to the current group ID; if 'blog', 125 * to the current blog's ID. If no 'item_id' can be determined in 126 * this way, the function returns false. Default: false. 127 * @type string $object The kind of object for which you're getting an 128 * avatar. BuddyPress natively supports three options: 'user', 129 * 'group', 'blog'; a plugin may register more. Default: 'user'. 130 * @type string $type When a new avatar is uploaded to BP, 'thumb' and 131 * 'full' versions are saved. This parameter specifies whether you'd 132 * like the 'full' or smaller 'thumb' avatar. Default: 'thumb'. 133 * @type string|bool $avatar_dir The name of the subdirectory where the 134 * requested avatar should be found. If no value is passed, 135 * 'avatar_dir' is inferred from 'object': 'user' becomes 'avatars', 136 * 'group' becomes 'group-avatars', 'blog' becomes 'blog-avatars'. 137 * Remember that this string denotes a subdirectory of BP's main 138 * avatar directory (usually based on {@link wp_upload_dir()}); it's a 139 * string like 'group-avatars' rather than the full directory path. 140 * Generally, it'll only be necessary to override the default value if 141 * storing avatars in a non-default location. Defaults to false 142 * (auto-detected). 143 * @type int|bool $width Requested avatar width. The unit is px. This value 144 * is used to build the 'width' attribute for the <img> element. If 145 * no value is passed, BP uses the global avatar width for this 146 * avatar type. Default: false (auto-detected). 147 * @type int|bool $height Requested avatar height. The unit is px. This 148 * value is used to build the 'height' attribute for the <img> 149 * element. If no value is passed, BP uses the global avatar height 150 * for this avatar type. Default: false (auto-detected). 151 * @type string $class The CSS class for the <img> element. Note that BP 152 * uses the 'avatar' class fairly extensively in its default styling, 153 * so if you plan to pass a custom value, consider appending it to 154 * 'avatar' (eg 'avatar foo') rather than replacing it altogether. 155 * Default: 'avatar'. 156 * @type string|bool $css_id The CSS id for the <img> element. 157 * Default: false. 158 * @type string $title The title attribute for the <img> element. 159 * Default: false. 160 * @type string $alt The alt attribute for the <img> element. In BP, this 161 * value is generally passed by the wrapper functions, where the data 162 * necessary for concatenating the string is at hand; see 163 * {@link bp_get_activity_avatar()} for an example. Default: ''. 164 * @type string|bool $email An email to use in Gravatar queries. Unless 165 * otherwise configured, BP uses Gravatar as a fallback for avatars 166 * that are not provided locally. Gravatar's API requires using a hash 167 * of the user's email address; this argument provides it. If not 168 * provided, the function will infer it: for users, by getting the 169 * user's email from the database, for groups/blogs, by concatenating 170 * "{$item_id}-{$object}@{bp_get_root_domain()}". The user query adds 171 * overhead, so it's recommended that wrapper functions provide a 172 * value for 'email' when querying user IDs. Default: false. 173 * @type bool $no_grav Whether to disable the default Gravatar fallback. 174 * By default, BP will fall back on Gravatar when it cannot find a 175 * local avatar. In some cases, this may be undesirable, in which 176 * case 'no_grav' should be set to true. To disable Gravatar 177 * fallbacks globally, see the 'bp_core_fetch_avatar_no_grav' filter. 178 * Default: true for groups, otherwise false. 179 * @type bool $html Whether to return an <img> HTML element, vs a raw URL 180 * to an avatar. If false, <img>-specific arguments (like 'css_id') 181 * will be ignored. Default: true. 182 * @type string $extra_attr HTML attributes to insert in the IMG element. Not sanitized. Default: ''. 183 * @type string $scheme URL scheme to use. See set_url_scheme() for accepted values. 184 * Default null. 185 * @type string $rating What rating to display Gravatars for. Accepts 'G', 'PG', 'R', 'X'. 186 * Default is the value of the 'avatar_rating' option. 187 * @type bool $force_default Used when creating the Gravatar URL. Whether to force the default 188 * image regardless if the Gravatar exists. Default: false. 189 * } 190 * @return string Formatted HTML <img> element, or raw avatar URL based on $html arg. 191 */ 192 function bp_core_fetch_avatar( $args = '' ) { 193 $bp = buddypress(); 194 195 // If avatars are disabled for the root site, obey that request and bail. 196 if ( ! $bp->avatar || ! $bp->avatar->show_avatars ) { 197 return; 198 } 199 200 // Set the default variables array and parse it against incoming $args array. 201 $params = wp_parse_args( $args, array( 202 'item_id' => false, 203 'object' => 'user', 204 'type' => 'thumb', 205 'avatar_dir' => false, 206 'width' => false, 207 'height' => false, 208 'class' => 'avatar', 209 'css_id' => false, 210 'alt' => '', 211 'email' => false, 212 'no_grav' => null, 213 'html' => true, 214 'title' => '', 215 'extra_attr' => '', 216 'scheme' => null, 217 'rating' => get_option( 'avatar_rating' ), 218 'force_default' => false, 219 ) ); 220 221 /* Set item_id ***********************************************************/ 222 223 if ( empty( $params['item_id'] ) ) { 224 225 switch ( $params['object'] ) { 226 227 case 'blog' : 228 $params['item_id'] = get_current_blog_id(); 229 break; 230 231 case 'group' : 232 if ( bp_is_active( 'groups' ) ) { 233 $params['item_id'] = $bp->groups->current_group->id; 234 } else { 235 $params['item_id'] = false; 236 } 237 238 break; 239 240 case 'user' : 241 default : 242 $params['item_id'] = bp_displayed_user_id(); 243 break; 244 } 245 246 /** 247 * Filters the ID of the item being requested. 248 * 249 * @since 1.1.0 250 * 251 * @param string $value ID of avatar item being requested. 252 * @param string $value Avatar type being requested. 253 * @param array $params Array of parameters for the request. 254 */ 255 $params['item_id'] = apply_filters( 'bp_core_avatar_item_id', $params['item_id'], $params['object'], $params ); 256 257 if ( empty( $params['item_id'] ) ) { 258 return false; 259 } 260 } 261 262 /* Set avatar_dir ********************************************************/ 263 264 if ( empty( $params['avatar_dir'] ) ) { 265 266 switch ( $params['object'] ) { 267 268 case 'blog' : 269 $params['avatar_dir'] = 'blog-avatars'; 270 break; 271 272 case 'group' : 273 if ( bp_is_active( 'groups' ) ) { 274 $params['avatar_dir'] = 'group-avatars'; 275 } else { 276 $params['avatar_dir'] = false; 277 } 278 279 break; 280 281 case 'user' : 282 default : 283 $params['avatar_dir'] = 'avatars'; 284 break; 285 } 286 287 /** 288 * Filters the avatar directory to use. 289 * 290 * @since 1.1.0 291 * 292 * @param string $value Name of the subdirectory where the requested avatar should be found. 293 * @param string $value Avatar type being requested. 294 * @param array $params Array of parameters for the request. 295 */ 296 $params['avatar_dir'] = apply_filters( 'bp_core_avatar_dir', $params['avatar_dir'], $params['object'], $params ); 297 298 if ( empty( $params['avatar_dir'] ) ) { 299 return false; 300 } 301 } 302 303 /* <img> alt *************************************************************/ 304 305 if ( false !== strpos( $params['alt'], '%s' ) || false !== strpos( $params['alt'], '%1$s' ) ) { 306 307 switch ( $params['object'] ) { 308 309 case 'blog' : 310 $item_name = get_blog_option( $params['item_id'], 'blogname' ); 311 break; 312 313 case 'group' : 314 $item_name = bp_get_group_name( groups_get_group( $params['item_id'] ) ); 315 break; 316 317 case 'user' : 318 default : 319 $item_name = bp_core_get_user_displayname( $params['item_id'] ); 320 break; 321 } 322 323 /** 324 * Filters the alt attribute value to be applied to avatar. 325 * 326 * @since 1.5.0 327 * 328 * @param string $value alt to be applied to avatar. 329 * @param string $value ID of avatar item being requested. 330 * @param string $value Avatar type being requested. 331 * @param array $params Array of parameters for the request. 332 */ 333 $item_name = apply_filters( 'bp_core_avatar_alt', $item_name, $params['item_id'], $params['object'], $params ); 334 $params['alt'] = sprintf( $params['alt'], $item_name ); 335 } 336 337 /* Sanity Checks *********************************************************/ 338 339 // Get a fallback for the 'alt' parameter, create html output. 340 if ( empty( $params['alt'] ) ) { 341 $params['alt'] = __( 'Profile Photo', 'buddypress' ); 342 } 343 $html_alt = ' alt="' . esc_attr( $params['alt'] ) .
