7. Interchange Page Display

Interchange has several methods for displaying pages:

• Display page by name
  If a page with [page some_page] or <A HREF="[area some_page]"> is called and that some_page.html exists in the pages directory (PageDir), it will be displayed.
• On-the-fly page
  If a page with [page 00-0011] or <A HREF="[area 00-0011]"> is called and 00-0011 exists as a product in one of the products databases (ProductFiles), Interchange will use the special page descriptor flypage as a template and build based on that part number. This is partly for convenience; the same thing can be accomplished by calling [page your_template 00-0011] and using the [data session arg] to perform the templating. But there is special logic associated with the PageSelectField configuration attribute to allow pages to be built with varying templates.
• Determine page via form action and variables
  If a form action, in almost all cases the page to display will be determined by the mv_nextpage form value. Example:

            <FORM ACTION="[process]">
            <INPUT TYPE=hidden NAME=mv_todo VALUE=return>
            <SELECT NAME=mv_nextpage>
            <OPTION VALUE=index>Main page
            <OPTION VALUE=browse>Product listing
            <OPTION VALUE="ord/basket">Shopping cart
            </SELECT>
            <INPUT TYPE=submit VALUE=Go>
            </FORM>

The mv_nextpage dropdown will determine the page the user goes to.
