contextual_range_filter.module in Views Contextual Range Filter 8

contextual_range_filter.module

Adds to Views an option to contextually filter by range. For instance, if you have a View with a float field (eg Price or Distance) and have added this field as the first contextual filter, then you can filter your View page like so:

http://yoursite.com/yourview/100--199.99

Date, number and string types are supported. Lists are really numbers. The OR ('+') operator is supported. The negate operator ("Exclude" tick box) is supported. "Glossary mode" (match on first N characters of a string) is supported.
