Skips processing the current row when the input value is empty.
The skip_on_empty process plugin checks to see if the current input value is empty (empty string, NULL, FALSE, 0, '0', or an empty array). If so, the further processing of the property or the entire row (depending on the chosen method) is skipped and will not be migrated.
Available configuration keys:
- method: (optional) What to do if the input value is empty. Possible values:
- row: Skips the entire row when an empty value is encountered.
- process: Prevents further processing of the input property when the value is empty.
- message: (optional) A message to be logged in the {migrate_message_*} table for this row. Messages are only logged for the 'row' method. If not set, nothing is logged in the message table.
Examples:
process:
field_type_exists:
plugin: skip_on_empty
method: row
source: field_name
message: 'Field field_name is missing'
If 'field_name' is empty, the entire row is skipped and the message 'Field field_name is missing' is logged in the message table.
process:
parent:
-
plugin: skip_on_empty
method: process
source: parent
-
plugin: migration_lookup
migration: d6_taxonomy_term
If 'parent' is empty, any further processing of the property is skipped and the next process plugin (migration_lookup) will not be run. Combining skip_on_empty and migration_lookup is a typical process pipeline combination for hierarchical entities where the root entity does not have a parent.
