StrMatch makes it easier to compare to textfields.

Sample Input:
StrMatch ( "AbcDef" ; "Def" ; "cn" ; True )
Sample Output:
True (1)

 Then copy & paste into FileMaker Advanced's Edit Custom Function window.


StrMatch makes it easier to compare to textfields.
With parameters 'comparemethod' and 'matchcase', various comparisons
can be performed.
The function returns a boolean number:
False (0) means both strings do not match
True (1) means the match is found

In: string1 - the textfield or literal string you want examined
string2 - the textfield or string you want to match against string1
comparemethod - a string containing one of the following commands:
eq - test if string 1 and string 2 are equal
neq - test if string 1 and string 2 are NOT equal
bw - test if string 1 begins with string 2
cn - test if string 1 contains string 2
ew - test if string 1 ends with string 2
gt - test if string 1 is greater than string 2
gte - test if string 1 is greater than or equal to string 2
lt - test if string 1 is less than string 2
gt - test if string 1 is less than or equal to string 2

matchcase - if set to True (any value not equal to zero)
the function does a Case Sensitive compare.
if False (0) the function behaves Case Insensitive

If an invalid comparemethod is given, the function compares for Equality

Syntax: StrMatch ( string1 ; string2 ; comparemethod ; matchcase )

Return type: Number (boolean)

This is my Custom Function and I want to edit it


How would I import this in filemaker pro 8 advanced?
Or is there already a version like this in Filemaker Pro 8 Advanced?

If so could you send me into the right direction. I only need the "cn" method.

Hi Anon,

i do not have pro 8 advanced, but i think this functio should work in that version aswell.

Have you tried adding it to your custom functions?

Great! this solved a problem that was even with some 'work--arounds' not solvable, as Filemaker Pro 11 does not have a clear function for exact comparison of strings... I had to clean up thousands of fields in a bibliographical database and peel out all those small variations made by typists/cataloguers over years (those without a proper library education and without proper tools)... my parsing script works perfect now... thanks again!
