When system doesn't have a field for necessary data |
A custom field is a system feature you can use to add your own fields to system objects.
You need to differentiate Custom fields in the system modules and iblock properties.
Custom fields are:
- more universal in contrast to iblock properties, because they can be specified for various system objects
- limited in features, because they have a small number of object types and data.
Custom fields can be created in an unlimited number for each object. When selecting a specific custom fields, additional settings become available for corresponding type.
When creating a custom field, you must indicate module-specific objects in the system:
| Built-in custom field objects
|
| Module | Object | Description |
| Kernel (main module) | USER | for user |
| Blogs | BLOG_BLOG | for blog |
| BLOG_POST | for blog post |
| BLOG_COMMENT | for message comment |
| Tasks | TASKS_TASK | for tasks |
| Information blocks | IBLOCK_N_SECTION | for iblock sections with ID = N |
| IBLOCK_N | for iblock with ID = N |
| Calendar | CALENDAR_EVENT | for calendar events |
| e-Learning | LEARN_ATTEMPT | for test attempts |
| Social Network | SONET_GROUP | for social network groups |
| Document library | WEBDAV | for document libraries |
| Forum | FORUM_MESSAGE | for forum messages |
| Highload-iblocks | HLBLOCK_N | for highload-block with ID=N |
|
Not all modules offer default objects for custom fields. Developer can create their own objects as required.
Note: All modules that utilize information blocks can access custom field objects of the Information blocks module.
