Public Properties ​
| Property | Description |
|---|---|
| behaviors | yii\base\Behavior – List of behaviors attached to this component. |
| db | craft\db\Connection, array, string – The database connection to use |
| deleteAllTrashed | boolean – Whether hardDelete() should delete all soft-deleted rows, rather than just the ones that were deleted long enough ago to be ready for hard-deletion per the config4:softDeleteDuration config setting. |
| probability | integer – The probability (parts per million) that garbage collection (GC) should be performed on a request. |
db ​
- Type
- craft\db\Connection, array, string
- Default value
'db'- Since
- 4.0.0
The database connection to use
deleteAllTrashed ​
- Type
- boolean
- Default value
false
Whether hardDelete() should delete all soft-deleted rows, rather than just the ones that were deleted long enough ago to be ready for hard-deletion per the config4:softDeleteDuration config setting.
probability ​
- Type
- integer
- Default value
10
The probability (parts per million) that garbage collection (GC) should be performed on a request. Defaults to 10, meaning 0.001% chance.
This number should be between 0 and 1000000. A value 0 means no GC will be performed at all unless forced.

deleteOrphanedFieldLayouts() ​
- Since
- 4.13.0
Deletes field layouts that are no longer used.
Arguments ​
$elementType(string) – The element type$table(string) – The table name that contains a foreign key tofieldlayouts.id$fk(string) – The column name that contains the foreign key tofieldlayouts.id
deletePartialElements() ​

hardDelete() ​
Hard-deletes any rows in the given table(s), that are due for it.
Arguments ​
$tables(string, string[]) – The table(s) to delete rows from. They must have adateDeletedcolumn.
hardDeleteElements() ​
- Since
- 4.0.0
Hard-deletes eligible elements.
Any soft-deleted block elements which have revisions will be skipped, as their revisions may still be needed by the owner element.
hardDeleteVolumes() ​
Hard delete eligible volumes, deleting the folders one by one to avoid nested dependency errors.
init() ​
Initializes the object.
This method is invoked at the end of the constructor after the object is initialized with the given configuration.
removeEmptyTempFolders() ​
- Since
- 4.0.0
Find all temp upload folders with no assets in them and remove them.
