Try using the Open URL script step.
I double vote Safari as web viewer. The FM web viewer seriously breaks many IOS features.
The OpenURL script step is what we need to open Safari not an answer.
Since this thread was first created, I've acquired an iPhone 4S. As a means of learning FM GO, I took the Known Bugs LIst Database that I created and maintain for the forum community and created a set of iPhone friendly layouts. Several of these layouts include URLs in fields with either a script trigger or a button that uses Open URL to open Safari to the specified URL.
None were modified to work with iOS. I didn't need to. They all successfully open Safari to the desired web page. You are welcome to download and examine this database in both FileMaker Go and Pro.
If, on the other hand, you want to view web pages on the iPhone via the FM Webviewer and it fails to work the way you need, that's a different issue. Specific failures in that regard should be posted to Report an Issue to make sure that the TS personnel that monitor that section know about the issue.
PS. the iPhone layouts only exist in the FileMaker 12 version of this database file.
That is great your iPhone 4S works. But that is in fact not the case on all iOS platforms. It worked in earlier versions of fm go but it currently does not
An unmodified URL with http: opened via the openurl script step opens a full screen fm web viewer window not iOS safari on an iPad. I currently have iOS 5 and 6. iPhone 4,4s,5 iPad 1-retina to test with. The only work around is to know the file type and hope you have a program that registers a custom URL type with iOS. This creates a scripting nightmare that requires all file types to modify the URL and on specific platforms. Bug maybe not a lacking functionality definitely.
Before you could let safari open the file and then use the safari open with button to choose the program. Tips functionality is now gone due to FM Go iPad not using safari any more.
I would like to see a super container URL on an fm go 12.0.7 iPad opened in safari via the openurl script step. If you can do it please share
I stand corrected. What I thought was Safari is as you describe a full page web viewer, not Safari. (either that or it's Safari with most of the features blocked--which makes no difference here in the results.
