Opening files using a URL
The FileMaker Pro installer registers fmp: as an Internet Protocol (IP). This enables you to open a shared or local file using a URL. You can also run a script in the file using a URL.
To open a file using a URL:
1. Launch a web browser on the intended client machine.
2. Enter the URL of the file into the browser’s address area using the format:
For address, you can enter:
the IP address or DNS name of the host
~ to specify the user’s Documents folder
$ to specify that the file is already open
Optional parameters are indicated by braces ({ }).
To run a script in a file using a URL:
1. Follow the steps above.
2. Append ?script=scriptname to the URL. For example:
Specify a script parameter and local variables using the format:
To allow a URL to run a FileMaker script, the user’s account must have the fmurlscript extended privilege enabled. See Editing extended privileges for a privilege set.
Filenames are case sensitive for FileMaker Go but not for FileMaker Pro. Script names are not case sensitive.
The filename extension .fmp12 is not required.
You can define multiple variables in the same fmp: protocol.
If spaces or any other special characters are needed in a link, be sure to replace them with the appropriate percent-encoded values required for valid URLs. For example, replace a space with %20.
