See {@link get_avatar()}. 145 * 146 * @param array|string $args { 147 * An array of arguments. All arguments are technically optional; some 148 * will, if not provided, be auto-detected by bp_core_fetch_avatar(). This 149 * auto-detection is described more below, when discussing specific 150 * arguments. 151 * 152 * @type int|bool $item_id The numeric ID of the item for which you're requesting 153 * an avatar (eg, a user ID). If no 'item_id' is present, 154 * the function attempts to infer an ID from the 'object' + the 155 * current context: if 'object' is 'user' and the current page is a 156 * user page, 'item_id' will default to the displayed user ID; if 157 * 'group' and on a group page, to the current group ID; if 'blog', 158 * to the current blog's ID. If no 'item_id' can be determined in 159 * this way, the function returns false. Default: false. 160 * @type string $object The kind of object for which you're getting an 161 * avatar. BuddyPress natively supports three options: 'user', 162 * 'group', 'blog'; a plugin may register more. Default: 'user'. 163 * @type string $type When a new avatar is uploaded to BP, 'thumb' and 164 * 'full' versions are saved. This parameter specifies whether you'd 165 * like the 'full' or smaller 'thumb' avatar. Default: 'thumb'. 166 * @type string|bool $avatar_dir The name of the subdirectory where the 167 * requested avatar should be found. If no value is passed, 168 * 'avatar_dir' is inferred from 'object': 'user' becomes 'avatars', 169 * 'group' becomes 'group-avatars', 'blog' becomes 'blog-avatars'. 170 * Remember that this string denotes a subdirectory of BP's main 171 * avatar directory (usually based on {@link wp_upload_dir()}); it's a 172 * string like 'group-avatars' rather than the full directory path. 173 * Generally, it'll only be necessary to override the default value if 174 * storing avatars in a non-default location. Defaults to false 175 * (auto-detected). 176 * @type int|bool $width Requested avatar width. The unit is px. This value 177 * is used to build the 'width' attribute for the <img> element. If 178 * no value is passed, BP uses the global avatar width for this 179 * avatar type. Default: false (auto-detected). 180 * @type int|bool $height Requested avatar height. The unit is px. This 181 * value is used to build the 'height' attribute for the <img> 182 * element. If no value is passed, BP uses the global avatar height 183 * for this avatar type. Default: false (auto-detected). 184 * @type string $class The CSS class for the <img> element. Note that BP 185 * uses the 'avatar' class fairly extensively in its default styling, 186 * so if you plan to pass a custom value, consider appending it to 187 * 'avatar' (eg 'avatar foo') rather than replacing it altogether. 188 * Default: 'avatar'. 189 * @type string|bool $css_id The CSS id for the <img> element. 190 * Default: false. 191 * @type string $title The title attribute for the <img> element. 192 * Default: false. 193 * @type string $alt The alt attribute for the <img> element. In BP, this 194 * value is generally passed by the wrapper functions, where the data 195 * necessary for concatenating the string is at hand; see 196 * {@link bp_get_activity_avatar()} for an example. Default: ''. 197 * @type string|bool $email An email to use in Gravatar queries. Unless 198 * otherwise configured, BP uses Gravatar as a fallback for avatars 199 * that are not provided locally. Gravatar's API requires using a hash 200 * of the user's email address; this argument provides it. If not 201 * provided, the function will infer it: for users, by getting the 202 * user's email from the database, for groups/blogs, by concatenating 203 * "{$item_id}-{$object}@{bp_get_root_domain()}". The user query adds 204 * overhead, so it's recommended that wrapper functions provide a 205 * value for 'email' when querying user IDs. Default: false. 206 * @type bool $no_grav Whether to disable the default Gravatar fallback. 207 * By default, BP will fall back on Gravatar when it cannot find a 208 * local avatar. In some cases, this may be undesirable, in which 209 * case 'no_grav' should be set to true. To disable Gravatar 210 * fallbacks globally, see the 'bp_core_fetch_avatar_no_grav' filter. 211 * Default: true for groups, otherwise false. 212 * @type bool $html Whether to return an <img> HTML element, vs a raw URL 213 * to an avatar. If false, <img>-specific arguments (like 'css_id') 214 * will be ignored. Default: true. 215 * @type string $extra_attr HTML attributes to insert in the IMG element. Not sanitized. Default: ''. 216 * @type string $scheme URL scheme to use. See set_url_scheme() for accepted values. 217 * Default null. 218 * @type string $rating What rating to display Gravatars for. Accepts 'G', 'PG', 'R', 'X'. 219 * Default is the value of the 'avatar_rating' option. 220 * @type bool $force_default Used when creating the Gravatar URL. Whether to force the default 221 * image regardless if the Gravatar exists. Default: false. 222 * } 223 * @return string Formatted HTML <img> element, or raw avatar URL based on $html arg. 224 */ 225 function bp_core_fetch_avatar( $args = '' ) { 226 $bp = buddypress(); 227 228 // If avatars are disabled for the root site, obey that request and bail. 229 if ( ! $bp->avatar || ! $bp->avatar->show_avatars ) { 230 return; 231 } 232 233 // Set the default variables array and parse it against incoming $args array. 234 $params = bp_parse_args( 235 $args, 236 array( 237 'item_id' => false, 238 'object' => 'user', 239 'type' => 'thumb', 240 'avatar_dir' => false, 241 'width' => false, 242 'height' => false, 243 'class' => 'avatar', 244 'css_id' => false, 245 'alt' => '', 246 'email' => false, 247 'no_grav' => null, 248 'html' => true, 249 'title' => '', 250 'extra_attr' => '', 251 'scheme' => null, 252 'rating' => get_option( 'avatar_rating' ), 253 'force_default' => false, 254 ) 255 ); 256 257 /* Set item_id ***********************************************************/ 258 259 if ( empty( $params['item_id'] ) ) { 260 261 switch ( $params['object'] ) { 262 263 case 'blog' : 264 $params['item_id'] = get_current_blog_id(); 265 break; 266 267 case 'group' : 268 if ( bp_is_active( 'groups' ) ) { 269 $params['item_id'] = $bp->groups->current_group->id; 270 } else { 271 $params['item_id'] = false; 272 } 273 274 break; 275 276 case 'user' : 277 default : 278 $params['item_id'] = bp_displayed_user_id(); 279 break; 280 } 281 282 /** 283 * Filters the ID of the item being requested. 284 * 285 * @since 1.1.0 286 * 287 * @param string $value ID of avatar item being requested. 288 * @param string $value Avatar type being requested. 289 * @param array $params Array of parameters for the request. 290 */ 291 $params['item_id'] = apply_filters( 'bp_core_avatar_item_id', $params['item_id'], $params['object'], $params ); 292 293 if ( empty( $params['item_id'] ) ) { 294 return false; 295 } 296 } 297 298 /* Set avatar_dir ********************************************************/ 299 300 if ( empty( $params['avatar_dir'] ) ) { 301 302 switch ( $params['object'] ) { 303 304 case 'blog' : 305 $params['avatar_dir'] = 'blog-avatars'; 306 break; 307 308 case 'group' : 309 if ( bp_is_active( 'groups' ) ) { 310 $params['avatar_dir'] = 'group-avatars'; 311 } else { 312 $params['avatar_dir'] = false; 313 } 314 315 break; 316 317 case 'user' : 318 default : 319 $params['avatar_dir'] = 'avatars'; 320 break; 321 } 322 323 /** 324 * Filters the avatar directory to use. 325 * 326 * @since 1.1.0 327 * 328 * @param string $value Name of the subdirectory where the requested avatar should be found. 329 * @param string $value Avatar type being requested. 330 * @param array $params Array of parameters for the request. 331 */ 332 $params['avatar_dir'] = apply_filters( 'bp_core_avatar_dir', $params['avatar_dir'], $params['object'], $params ); 333 334 if ( empty( $params['avatar_dir'] ) ) { 335 return false; 336 } 337 } 338 339 /* <img> alt *************************************************************/ 340 341 if ( false !== strpos( $params['alt'], '%s' ) || false !== strpos( $params['alt'], '%1$s' ) ) { 342 343 switch ( $params['object'] ) { 344 345 case 'blog' : 346 $item_name = get_blog_option( $params['item_id'], 'blogname' ); 347 break; 348 349 case 'group' : 350 $item_name = bp_get_group_name( groups_get_group( $params['item_id'] ) ); 351 break; 352 353 case 'user' : 354 default : 355 $item_name = bp_core_get_user_displayname( $params['item_id'] ); 356 break; 357 } 358 359 /** 360 * Filters the alt attribute value to be applied to avatar. 361 * 362 * @since 1.5.0 363 * 364 * @param string $value alt to be applied to avatar. 365 * @param string $value ID of avatar item being requested. 366 * @param string $value Avatar type being requested. 367 * @param array $params Array of parameters for the request. 368 */ 369 $item_name = apply_filters( 'bp_core_avatar_alt', $item_name, $params['item_id'], $params['object'], $params ); 370 $params['alt'] = sprintf( $params['alt'], $item_name ); 371 } 372 373 /* Sanity Checks *********************************************************/ 374 375 // Get a fallback for the 'alt' parameter, create html output. 376 if ( empty( $params['alt'] ) ) { 377 $params['alt'] = __( 'Profile Photo', 'buddypress' ); 378 } 379 $html_alt = ' alt="' . esc_attr( $params['alt'] ) .
