Hi!
I have 2 questions. The first one will be easy to answer and the second one probably will require some good knowledge about php.

1- The Hidden type in html, as i understand its acting like a Flag variable???

2- I have 3 dropdown box. The first one contains year, 2001,2002,2003...
the second one is months and the thir one is for days.

I want to display the second dropdown box (months) ONLY if the year is selected.
and do the same thing for displaying the days.

I want to do the same thing as Compaq on their site when you select a Serie.

look at the URL : http://web14.compaq.com/falco/sp_list.asp

1. Not sure what you mean, do you mean the input hidden type???

This is just to pass information from a form either:

a) so the user cannot see what your passing,
b) or information that really isn't worth printing to screen.

2.

Two way, either have ALL the data on the page and use JavaScript to update the combos, using OnChange etc..

or when one selection is made, again using OnChange load another PHP file and process the date(s) and print the relivant info.

If you have a slow link or don't want to keep loading other pages up JavaScript is good enough.

1. <input type='hidden' name='variablename' value='variable content'>
   It can be used as a flag but it is the generic method of passing variables that are not to be changed or displayed in the HTML form.

2. Changing what is displayed without reloading the page requires a client-side scripting utility as well.

The page has to be reloaded. for each combos to appear.

then one way would be:

if($year)
{
// insert your month select box here
if($month)
{
// insert your day select box here
}
}
