Hi All!!

I have a CMS HasManyComplexTableField with fields and I have thousands of records there. I want to have fields above to set some filter options, for example

TextField('Country')
FormAction(???)

If I press Submit button I will see my table with appropriate records by country (less then thousands). I've trying to solve this problem all over the day but I couldn't :...((((

Also I don't know how to make this functionality in SilverStripe:

In mypage.php is
<form action="mypage.php" method="get">
First name: <input type="text" name="fname" /><br />
Last name: <input type="text" name="lname" /><br />
<input type="submit" value="Submit" />
</form>

i don't know how to put "mypage.php" into FormAction(...) instead of function name.

If I use Director::redirectBack() I loose all my POST, GET data ((

Help me pleeeease!! :....(
