We recommend this chapter for everyone, including beginners and advanced developers: Working with portals is a fundamental part of becoming adept with FileMaker, for whatever purpose. This chapter begins by covering some basic portal details, but after we've moved through that information, we get to some more advanced techniques. Portals can be used whenever a developer needs to display n rows of virtually anything on a layout. They can even be used to present navigation or function options to users, display images, or offer alternative list views combined with form views of data. They can be used to display ad hoc reports. Launch FileMaker Pro 6 and export XML with FMPXMLRESULT grammar from any of your databases or use the Export.fp5 database found in Chapter 2. They can be used to present a pick list for selecting records for various functions. 8.11 Create a Database with FMPXMLRESULT This example shows how an XML document formatted in the FMPXMLRESULT grammar can be used to create a new FileMaker Pro 6 database. Portals can also serve a wide variety of user interface needs. This is especially true if you make use of portal functionality allowing for the creation of related records portals then can serve as the mechanism by which related records are created. Portals in cases like this reflect the primary relationships in a database. For example, a record for a neighborhood might show all the related house records in a portal, or a record for a class might show a portal of all the students enrolled in that class. In their most basic form they display data that pertains to the essential relationships in a given system. Portals are important tools in the FileMaker toolbox.
