migrate_fixed_to_text()

Description

Migrate fixed list field data to text field data for a given resource reference. Useful when changing resource type field from a data type
that can contain multiple values such as a dynamic keywords field. This script will concatenate the existing values and leave one remaining
node for the new text field.

- additional checks maybe need before calling this to ensure the fields are / were of the expected type.
see examples in pages/tools/migrate_fixed_to_text.php
of category tree branches to be preserved e.g. "level1/value, level2/value"

Parameters

ColumnTypeDefaultDescription
$resource_type_field mixed Resource type field id. ** The field type should have been changed to a text type in advance
$resource mixed Resource reference to be processed.
$category_tree mixed Was the field data being migrated previously of type category tree? Specifying true will allow the format
$separator mixed ' Default is comma and space e.g. "value1, value2"
: ' get_resource_nodes$resource
true
# SORT_ASC;

Return

bool True on success else false.
