I can't get date values using $_GET In my view, I have two filters: title (text box), and date (combobox); date has two values: year and month.  

When I select the filters parameters in the view, and I click search, the filter values appears in the URL such as in mysite/views-path?title_filter=aaa&amp;date_filter[year][value]=2012&amp;date_filter[month][value]=3.  

I used $_GET to get the value of the title filter, and it worked, but I can't get the date values using print $_GET['date_filter[year][value]'];.  

Can anyone tell me how to get values like date using $_GET?
Arrays in query strings get converted into actual PHP arrays when you use $_GET.

To get the value in your case you'd use something like:

print $_GET['date_filter']['year']['value'];
