from form into database using different generated ids

[bajer]

I have a page displaying products, once its displaying them, you are able to select how many qty you want from each one...
So I am generating automatic:

 <input type="text" name="<? echo "$id"; ?>" size="5">

so the name of the filed would be the id of the product (and it could be any #, some have been deleted therefore there is no #2 already:
$82 which = 4
$12 which = 2
$79 which = 24

Now, when I post information: I want to be able to store them
order_id id order_qty

273457 82 4
273457 12 2

273457 79 24

So I was thinking of using foreach $id # that is more than 0, INSERT into database $order_id, $id, $order_qty

Any help in this is greatly appreciated
P.s. - My idea here is not to input 0's into database, as it would be useless, so if there was a product 14 that was not selected, there is no point of enlarging database.

Thanks

simply check to see of the submitted text fields have been filled out or not and conditionally insert into the database:

foreach ($_POST as $value)
{
	if ($value)
	{
		// insert into the order table
	}	
}

Thank you this works great, to get the value, but
how can I get what id it was???

[devinemke]

foreach ($_POST as $key => $value) 
{ 
    if ($value) 
    { 
        // insert into the order table, $key is the id#
    }     

}
