Still having a form problem

Hi there everyone, I'm still having problems with my form PHP data, I lost email for a couple of days due to a server crash on my account so don't know if this was answered or not (Sorry). Basically, I have a form which populates 25 entries at a time from a MySQL DB with PHP, you can select the product you want to order by entering a value in the quantity box, if it was a single box it wouldn't be a problem, but it's an array. Now again, an array for the quantity is no problem at all, as I just use <input name="quantity[]" type="text" class="style8" id="quantity[]" value="" size="5"> HOWEVER, I also need to transfer the $id (Named $id_new) from the database in each quantity array at the same time so I can split each array into ID and QUANTITY, this way I know which ID has which quantity, but this is what has me stumped. I tried with a HIDDEN field but of course that won't work, as there's no way of aligning which ID goes with which quantity, so what I guess I need to know, is how to amend $id_new with the quantity[] array. Any help would be REALLY appreciated as this is really urgent. Chris
