Hi,
​
I have a dropdown with year
=Year
2011=2011
2012=2012
2013=2013
2014=2014
2015=2015
2016=2016
2017=2017
2018=2018
​
when year selected the filter should not appear in query
​
versions.programs_id:{data:sel_programs}/-
year(enrollments.exam_passed):{data:sel_year}/-
enrollments.exam_score/>=:{data:sco_min}/-
enrollments.exam_score/<:{data:sco_max}/-
​
and it apears and make filter on empty date (0000). so i would want all year
​
regards
Chris

Hi Chris,
​
The "-" will not be enough here, you will need a PHP action to check the value and unset it if its empty

Hi Max,
​
this is not very easy. Until now we don't need to do that.

Hi Chris,
​
Not very difficult too, just the code below:

if(empty($this->data("sel_year"))){
$this->set("sel_year", null);
}else{
$this->set("sel_year", $this->data("sel_year"));
}

Then use {var:sel_year} in your code!
​
Best regards

thanks Max
