Insert From URL Un-encodes some encoded values


FileMaker Pro


FMPA 12.0v3

Operating system version

Mac OS 10.8.3

Description of the issue

When you're sending data to a Web Service using the Insert From URL step, you need to encode the data using GetAsURLEncoded first.

However, the script step is modifying the encoded data before sending it to the server, and this can either cause data issues or break the url.

For example this string :


contains 2 fields.  One is "abc" and the other is "abc&def" but encoded to %26.  But the value that FMP is sending to the server is actually


Meaning that field2 gets the wrong value, and there's likely an issue with the non-existent "def" field.

FileMaker also unencodes commas and @ symbols.

Steps to reproduce the problem

Generate an Insert URL Script step from field data with &, @ or commas.

Check using a tcp dump tool, or server side logs to compare the calculated request with the request that fmp sends.

I can generate sample urls that you can send dummy data to if you'd like.

Expected result

FileMaker shouldn't alter the url before sending it, all encoding is the job of the developer.

Actual result

FileMaker modifies the url before sending it, but only for some values.

If you do not run the Web service at the other end, then there is no workaround until it's fixed.
