Guide to Updating Plug-ins

12 FileMaker Server Guide to Updating Plug-ins
6. Write a script that converts version information to number format and places the result in additional
global fields in your Auto Update layout.
This conversion to number format is required for a comparison of the plug-in version information
collected from the client and server computers.
For script syntax, see the Get Version Numbers script in the AutoUpdatePlugin.fp7 sample file.
For information about the GetAsNumber function, see the FileMaker Pro Help.
7. Write a script to download the plug-in from the server computer, if the version on the client computer
doesn’t exist or is outdated.
For script syntax, see the Download Plug-In script in the AutoUpdatePlugin.fp7 sample file. For
information about the FMSAUC_UpdatePlugIn function, see
“FMSAUC_UpdatePlugIn” on page 14.
8. Write a “parent” script to:
1 make sure the Auto Update plug-in exists and is enabled on the client computer
1 run the individual version checking and downloading scripts you wrote earlier
For script syntax, see the Run Plug-in Scripts script in the AutoUpdatePlugin.fp7 sample file. For
information about the FMSAUC_Version function, see
“FMSAUC_Version” on page 12.
