NAME¶
HTML::FormFu::Filter::ForceListValue - convert a single value into a 1-item-list
SYNOPSIS¶
element:
- type: Repeatable
increment_field_names: 0
elements:
- name: foo
render_processed_value: 1
filter:
- ForceListValue
DESCRIPTION¶
Causes a single submitted value to be changed to a list containing 1 item.
Solves an uncommon problem with a Repeatable block with increment_field_names
disabled, when manually increasing the repeat count after the form was
submitted with only a single value for each of the Repeatable's fields.
If these circumstances, when rendered, every repeated field would have the
initially-submitted value as its default.
Using this filter, and setting render_processed_value to "true" will
ensure that only the first repetition of each field will have the submitted
value as its default; all subsequent repetitions will have no default value.
