MAC Address Validation

[Charlih Chen]

Q1: How to validate the MAC Address in the format:

####:##:##:##:##

Q2: How to convert the wrong format to the right format.

For example, convert from ##-##-##-##-##-## to ##:##:##:##:##:##

I have search the web, and there is function look like : (^([0-9a-fA-F][0-9a-fA-F]){5}([0-9a-fA-F][0-9a-fA-F])).

Can FM Pro7 do such function?

What you are displaying is a Regular Expression (Grep Pattern) and Filemaker doesn't use them very will. Most of the time it is better to either use the Grep find and replace before the data is imported, OR to use the substitute, left, right and middle functions to parse it out.

If this data is in a field all by itself, you can use the function to replace the "-" with ".". IF that is the case, try using the Menu, Replace Content function

with this calculation,

Substitute ( YourField; "-"; ".")

I tried the following for a Validation calc and it appears to work.

//Validate Hex characters

not IsEmpty(Filter (Middle(MAC_Add;1;1) ;"ABCDEF0123456789")) and

not IsEmpty(Filter (Middle(MAC_Add;2;1) ;"ABCDEF0123456789")) and

not IsEmpty(Filter (Middle(MAC_Add;4;1) ;"ABCDEF0123456789")) and

not IsEmpty(Filter (Middle(MAC_Add;5;1) ;"ABCDEF0123456789")) and

not IsEmpty(Filter (Middle(MAC_Add;7;1) ;"ABCDEF0123456789")) and

not IsEmpty(Filter (Middle(MAC_Add;8;1) ;"ABCDEF0123456789")) and

not IsEmpty(Filter (Middle(MAC_Add;10;1) ;"ABCDEF0123456789")) and

not IsEmpty(Filter (Middle(MAC_Add;11;1) ;"ABCDEF0123456789")) and

not IsEmpty(Filter (Middle(MAC_Add;13;1) ;"ABCDEF0123456789")) and

not IsEmpty(Filter (Middle(MAC_Add;14;1) ;"ABCDEF0123456789")) and

not IsEmpty(Filter (Middle(MAC_Add;16;1) ;"ABCDEF0123456789")) and

not IsEmpty(Filter (Middle(MAC_Add;17;1) ;"ABCDEF0123456789")) and

//Validate semicolon as seperators

not IsEmpty(Filter(Middle(MAC_Add;3;1);";")) and

not IsEmpty(Filter(Middle(MAC_Add;6;1);";")) and

not IsEmpty(Filter(Middle(MAC_Add;9;1);";")) and

not IsEmpty(Filter(Middle(MAC_Add;12;1);";")) and

not IsEmpty(Filter(Middle(MAC_Add;15;1);";"))

There might be a better formula, not sure. *note I added the following auto-enter calc (set to replace existing value) for the Mac_Add field --- Upper(Mac_Add). This way lowercase hex characters are accepted.
