I had need to make changes to the html_select_date plugin.

Specifically, I needed the ability to have zero date selected if the date I was
passing was in fact empty. If I didn't, then when my form was submitted I would
have got todays date - I needed to keep that date empty by default if it was
originally empty and with the current setup that's not possible.

I noticed that passing "-1" as the "time" value would give me a way to retain
the useful "give the current date if no date passed" feature.

Here's my html_select_date function call :

{html_select_date prefix="payment_" time=$os.payment_date|default:-1}

so if there hasn't been a payment_date, make sure we don't suggest one.

Several changes are required in the function.html_select_date.php file :

1. Add $month_names[] = "..."; 
   below $month_names = array();

2. change 
   'values' => range(1, 12),   to
   'values' => range(0, 12),
 in the $month_result .= smarty_function_html_options call.

3. add array_unshift($days, "..");
   below $days[$i] = sprintf($day_format, $days[$i]);

4. change
   'values' => range(1, 31),   to
   'values' => range(0, 31),
  in the $day_result .= smarty_function_html_options call.

5. add
   $years_vals = $years;
   $years_show = $years;
   array_unshift($years_show, "....");
   array_unshift($years_vals, "0");

   below 
   if ($reverse_years) {
       rsort($years, SORT_NUMERIC);
   }

   (for completeness should also deal with the "if ($year_as_text)" case too.)

6. change 

   'output' => $years,
   'values' => $years,

   to

   'output' => $years_show,
   'values' => $years_vals,

  in the $year_result .= smarty_function_html_options call.

This way, I get a nice collection of ".. ... ...." in my dropdowns, and no date
data gets passed back by accident.

Cheers,

Gavin
