| 12 |
* This function runs the typical content processing filters that WordPress |
| 13 |
* applies to post content, useful for blocks that render nested content. |
| 14 |
* |
| 15 |
* The filters applied in order are: |
| 16 |
* - shortcode_unautop() |
| 17 |
* - do_shortcode() |
| 18 |
* - do_blocks() |
| 19 |
* - wptexturize() |
| 20 |
* - convert_smilies() |
| 21 |
* - wp_filter_content_tags() |
| 22 |
* - $wp_embed->autoembed() |
| 23 |
* |
| 24 |
* Optionally supports recursion prevention by accepting a seen IDs array |
| 25 |
* and an ID. When provided, the ID is added to the array before do_blocks() |
| 26 |
* and removed after, preventing infinite loops when content references itself. |

* @param string $content The content to process. |
| 33 |
* @param string $context Optional. Context identifier for wp_filter_content_tags. Default empty string. |
| 34 |
* @param array|null $seen_ids Optional. Reference to array tracking seen IDs for recursion prevention. Default null. |
| 35 |
* @param string|null $id Optional. Unique identifier for this content, used with $seen_ids. Default null. |
| 36 |
* @return string The processed content. |
