Date Field Filter
Date Field Filter allows you to display weblog entries based on a custom date field timeframe. Integrating within the Weblog:Entries function, and using a simple method of specifying the custom date field name and a Start and Stop date through a few parameters, you can display entries based on dates specified in custom date fields.
Important: The use of this extension requires that an additional extension hook be added to the mod.weblog.php file of your EE install.
NOTE: This Add-On requires ExpressionEngine 1.6+, PHP 5+, and MySQL 4.1+.
