checkbox

Name

checkbox — return user-supplied value if its length is 1 or more, an empty string otherwise

DESCRIPTION

The filter checks for the length of input. When the length of input is non-zero, the filter returns input itself. When the length is zero, the filter returns an empty string.

The filter is suitable for retrieving values out of HTML checkboxes.

EXAMPLES

No examples are available at this time. We do consider this a problem and will try to supply some.
