For my personnal purpose, I have changed some code in the html_select_date (file ....lib\smarty\plugins\function.html_select_date.php).
Explainations:
I need date lists for optionally entering dates : Lists must be able to present an empty option as selected value at start, and return a value considered as null (like date 0000-00-00).
I want also those lists to be able to have a selected date (given as parameter) shown selected at start.
I want to have several html_select_date lists in the same form to be able to select interval dates
So I added 3 optionnal parameters:
'selected date' = $value where $value is a yyyy-mm-dd date
'zero' = $value where $value take any not null value.
'postfix' = $value (where $value uses to be "[]"). This $value is concatened at the end of the name of lists. "[]" enable PHP to take is as an array member.
My code may be improved (the "date_default_timezone_set('Europe/Paris')" as to be changed or removed) but if functions well right now. My comments are in french. This is my version of the html_select_date.php file.

Exemples of use:
Modifiable date in a presentation form:
{html_select_date id="DATE[]" start_year="1984" end_year="+1" selected_date=$MyObject->getMyDate()}
Optional date in a search form:
{html_select_date zero="true" id="DATE[]" start_year="1984" end_year="+1"}
Group of html_select_date lists to select an interval of time:
{html_select_date id="DATE[]" postfix="[]" start_year="-10"}{html_select_date id="DATE[]" postfix="[]" end_year="+10"}
All those parameters at the same time:
{html_select_date zero="true" id="DATE[]" postfix="[]" start_year="-10" selected_date=$yesterday}
{html_select_date zero="true" id="DATE[]" postfix="[]" end_year="+10" selected_date=$tomorrow} |
