Description:

This function will split up a string based on a character you specify and then return one of the values. Its a simple but useful way to get multiple parameters using FMP7's Get( ScriptParameter ) script step. Just call a script using "parameter1|parameter2|parameter n" and use this function to get the value you want.

Note: these functions are not guaranteed or supported by BrianDunning.com. Please contact the individual developer with any questions or problems.

This is my Custom Function and I want to edit it

Discuss:

This function, as written doesn't prooperly handle an occurrance that is greater than the number of actual occurrances in the string. Where it should return nothing it returns multiple values.

Let( [

startPos = Position ( string ; character ; 1 ; occurrence - 1 );
endPos = Position ( string ; character ; 1 ; occurrence );
argLen = endPos - startPos;
count = PatternCount ( string ; character )

];

Case (
occurrence ≤ count ; Middle ( string ; startPos + 1 ; argLen - 1 ) ;
occurrence = count + 1 ; Middle( string ; startPos + 1; Length ( string ) - startPos );
""
)

)

Here's a slightly updated function that takes multiple-length characters into account (I wrote this to be able to split on " OR " in search queries.

Returns the occurence without the search characters.

One situation this doesn't account for, though, is if your character occurs at the very start of the string (" OR search term").

Let( [

charLen = Length ( character );
startPos = Position ( string ; character ; 1 ; occurrence - 1 );
endPos = Position ( string ; character ; 1 ; occurrence );
argLen = endPos - startPos;
count = PatternCount ( string ; character )

];

Case (
occurrence = 1 ; Middle ( string ; startPos ; argLen - 1 ) ;
occurrence ≤ count ; Middle ( string ; startPos + charLen ; argLen - charLen ) ;
occurrence = count + 1 ; Middle( string ; startPos + charLen; Length ( string ) - startPos );
""
)

)
