Custom Column - Split Multi Values

nynaevelan · 10-27-2014, 02:00 AM

Hi:

I need a little help trying to create a custom column based off of a previous custom column which has multi-values. I would like to create the second custom column which would output only the first value of the first custom column. Can someone help me set this up?

This should do it after you replace #mytextmult with the name of your multi-valued column

Code:

program: sublist(field('#mytextmult'), 0, 1, ',')

What if I want only the second or third value?

Change the "0, 1" to select the value(s) you want. Quoting the documentation for sublist:

Quote:

sublist(val, start_index, end_index, separator) – interpret the value as a list of items separated by separator, returning a new list made from the start_index to the end_index item. The first item is number zero. If an index is negative, then it counts from the end of the list. As a special case, an end_index of zero is assumed to be the length of the list. Examples using basic template mode and assuming that the tags column (which is comma-separated) contains “A, B, C”: {tags:sublist(0,1,,)} returns “A”. {tags:sublist(-1,0,,)} returns “C”. {tags:sublist(0,-1,,)} returns “A, B”.
