I understand you want to post the data to a php script. The page with the post data has many buttons
and you don't know how to tell it to post the date no matter which button is pressed. Right?
The following form covers all the buttons and auction formating html code
<form method="POST">
<input type="hidden" name="date " value="%your date value%">
<input type="hidden" name="time " value="%your time value%">
<!-- EXTRA HTML CODE HERE FOR AUCTIONS -->
<input type="submit" name="auction_category_button[0]" value="Acept">
<!-- EXTRA HTML CODE HERE FOR AUCTIONS -->
<input type="submit" name="auction_category_button[1]" value="Acept">
<!-- EXTRA HTML CODE HERE FOR AUCTIONS -->
<input type="submit" name="auction_category_button[2]" value="Acept">
<!-- EXTRA HTML CODE HERE FOR AUCTIONS -->
<input type="submit" name="auction_category_button[3]" value="Acept">
<!-- ETC.... -->
</form>
Then on the php script you check to si if the selected button is set or not. If for example
category 2 was selected you should have a auction_category_button variable set with a key 2.
So you can work from that. Obviously you can change the numbers to something more
representative like cars, jewelry, houses, etc. Anyway no matter which button gets pressed all
the hidden variables (date, time) are posted too.
Hope it helps.
