class ArrayPop in Migrate Plus 8.5
Same name and namespace in other branches
- 8.4 src/Plugin/migrate/process/ArrayPop.php \Drupal\migrate_plus\Plugin\migrate\process\ArrayPop
Performs an array_pop() on a source array.
@MigrateProcessPlugin( id = "array_pop", handle_multiples = TRUE )
The "extract" plugin in core can extract array values when indexes are already known. This plugin helps extract the last value in an array by performing a "pop" operation.
Example: Say, the migration source has an associative array of names in a property called "authors" and the keys in the array can vary, you can extract the last value like this:
last_author:
plugin: array_pop
source: authors
