Search by month
I want to add a drop down box to a page that lists the months of the year with the values being set as 01 for Jan, 02 for Feb etc and then search a date field in a database for months that match the value the user chose from the drop-down.
The form uses the GET method so I've set the filter to be where the field DateCourseCompleted = to a URL parameter also called DateCourseCompleted.
When I click the search button it takes me to a blank search page, rather than posting back to itself, even though the form action is set to PHP_SELF
