* Attempts to refer to the inner-block wrapping element by its class attribute. |
| 1227 |
* |
| 1228 |
* When examining a block's inner content, if a block has inner blocks, then |
| 1229 |
* the first content item will likely be a text (HTML) chunk immediately |
| 1230 |
* preceding the inner blocks. The last HTML tag in that chunk would then be |
| 1231 |
* an opening tag for an element that wraps the inner blocks. |
| 1232 |
* |
| 1233 |
* There's no reliable way to associate this wrapper in $block_content because |
| 1234 |
* it may have changed during the rendering pipeline (as inner contents is |
| 1235 |
* provided before rendering) and through previous filters. In many cases, |
| 1236 |
* however, the `class` attribute will be a good-enough identifier, so this |
| 1237 |
* code finds the last tag in that chunk and stores the `class` attribute |
| 1238 |
* so that it can be used later when working through the rendered block output |
| 1239 |
* to identify the wrapping element and add the remaining class names to it. |
| 1240 |
* |
| 1241 |
* It's also possible that no inner block wrapper even exists. If that's the |
| 1242 |
* case this code could apply the class names to an invalid element. |
| 1243 |
* |
| 1244 |
* Example: |
| 1245 |
* |
| 1246 |
* $block['innerBlocks'] = array( $list_item ); |
| 1247 |
* $block['innerContent'] = array( '<ul class="list-wrapper is-unordered">', null, '</ul>' ); |
| 1248 |
* |
| 1249 |
* // After rendering, the initial contents may have been modified by other renderers or filters. |
| 1250 |
* $block_content = <<<HTML |
| 1251 |
* <figure> |
| 1252 |
* <ul class="annotated-list list-wrapper is-unordered"> |
| 1253 |
* <li>Code</li> |
| 1254 |
* </ul><figcaption>It's a list!</figcaption> |
| 1255 |
* </figure> |
| 1256 |
* HTML; |
| 1257 |
* |
| 1258 |
* Although it is possible that the original block-wrapper classes are changed in $block_content |
| 1259 |
* from how they appear in $block['innerContent'], it's likely that the original class attributes |
| 1260 |
* are still present in the wrapper as they are in this example. Frequently, additional classes |
| 1261 |
* will also be present; rarely should classes be removed. |
| 1262 |
* |
| 1263 |
* @todo Find a better way to match the first inner block. If it's possible to identify where the |
| 1264 |
* first inner block starts, then it will be possible to find the last tag before it starts |
| 1265 |
* and then that tag, if an opening tag, can be solidly identified as a wrapping element. |
| 1266 |
* Can some unique value or class or ID be added to the inner blocks when they process |
| 1267 |
* so that they can be extracted here safely without guessing? Can the block rendering function |
| 1268 |
* return information about where the rendered inner blocks start? |
