Classification::Classification (   $ClassId,
  $Name = NULL,
  $FieldId = NULL,
  $ParentId = NULL 
)

Class constructor.

This can be used both to access an existing classification or to add a new classification to a hierarchy. For existing classifications specify just the Classification ID. For new classifications, pass in NULL for the Classification ID, and specify all of the other parameters.

Parameters
int | null$ClassIdID of Classification. Use NULL to create a new Classification.
string$NameFull name or segment name for new Classification. Segment name can be used if a parent ID is also supplied, otherwise full name is assumed. (OPTIONAL)
int$FieldIdMetadataField ID for new Classification. (OPTIONAL)
int$ParentIdID of parent in hierachy of for new Classification. Use -1 for new Classification with no parent (i.e. at top level of hierarchy). (OPTIONAL)

Here is the caller graph for this function:

Classification::Delete (   $DeleteParents = FALSE,
  $DeleteIfHasResources = FALSE,
  $DeleteIfHasChildren = FALSE 
)

Remove Classification (and accompanying associations) from database.

Parameters
bool$DeleteParentsFlag indicating whether to also delete Classification entries above this one in the hierarchy. (OPTIONAL
  • defaults to FALSE)
bool$DeleteIfHasResourcesFlag indicating whether to delete the Classification if it still has Resources associated with it. (OPTIONAL - defaults to FALSE)
bool$DeleteIfHasChildrenFlag indicating whether to delete the Classification if others have it as a parent. (OPTIONAL - defaults to FALSE)

Classification::FieldId (   $NewValue = DB_NOVALUE)

Get or set the ID of the MetadataField for the Classification.

Parameters
