Script Required to Display Multiple Product ID's

Our website sells various different products. We have a php script that creates a PDF document/brochure for each different product, with a predetermined layout, based on information from selected pages on our website (from mysql database). We have various php files depending on which layout is required i.e. double page spread, 8 images, 16 images etc. However at the moment we can only can produce one PDF per product ID at one time. So for 8 products we have 8 separate PDF files – we just want one. We require a script whereby we can assign multiple product ID’s to any type of our predetermined layouts and to create one PDF file that contains all the selected product ID’s and the assigned layouts together. i.e. - product ID 1 is assigned to layout 1 - product ID 2 is assigned to layout 6 - product ID 3 is assigned to layout 1 We also require some templates to display data from up to 8 different product ID’s (we have the template already designed). These 8 products will be assigned to one particular store/branch (which we have already defined in the database). So in summary, you will need to create a page in our admin section which lists the various products listed on our website and the option to select which type of layout we require (possibly a drop down) for the PDF. There will then be the option for the user to create the pdf. Just to recap we already have the script set up to create individual PDFs, we just need it to create one PDF based on an unlimited number of product ID’s and different types of layout.
