make_filename

Description

The make_filename operator takes any text and turns it into a safe file name. Uppercase letters are turned to lowercase and illegal characters like e.g. /, $, |, -, or $ are removed from the given text.

Example: Filename from Just Text

make_filename("Holiday Pictures 2012 & 2013")

This will return a string that looks like this: holiday_pictures_2012_2013

Example: Filename from Information

You can also use make_filename in combination with other operators and information from a case.

p is Person
make_filename(
    JOIN(
        (
            p.date_of_birth,
            p.first_name + ' ' + p.last_name
        ),
        " - "
    )
)

If both pieces of information are known, you would get a string that could look like this:

1987_02_28_thorben_croise
