Scanning barcodes from FileMaker Go

FileMaker Go 1.1.1 supports a new fmp7script URL scheme that allows communication with external iOS apps. Thanks to a tip from Jeremy Bante at Kyo Logic, I found a free iOS app that can scan barcodes and works with this new feature in FileMaker Go. The app is pic2shop from Vision Smarts.

This article shows you how to integrate FileMaker Go with pic2shop to scan barcodes.

Integrating FileMaker Go with pic2shop requires just two scripts.

The first script – “Open pic2shop app” – uses the Open URL script step to launch the URL, which opens the pic2shop app and asks it to scan a barcode.

A FileMaker calculation for the URL looks something like this:

"pic2shop://scan?callback=fmp7script%3A//%24/" & Get ( FileName ) & "%3Fscript%3DScan%26param%3DEAN"

Note that the callback parameter in the URL has to be encoded. Without the encoding, the URL would look like this:

pic2shop://scan?callback=fmp7script://$/BarcodeTest?script=Scan&param=EAN

When pic2shop receives this URL, it will scan a barcode and return the result as a script parameter to the “Scan” script in the hibernated FileMaker Go file that sent the URL.

The second script – “Scan” – takes over from there and processes the scanned value.
