I need to build form with custom operations (like Excel) and wonder how to do it.
Example form, 4 fields:
row #1
1. [input data $1]
2. [input data $2]
3. [input data $3]
4. [custom operations data in any format]
row #2
1. [input data $1]
2. [input data $2]
3. [input data $3]
4. [custom operations data in any format]
So, user puts:
ROW #1
1. 2
2. 2
3. 3
4. #1$2*#1$2*#1$3 (# = row, $ = field, score = 12)
ROW #2
1. 1
2. 4
3. 5
4. #1$2*#2$2+#2$3 (score = 2*4+5 = 13)
How to build function who count string in custom operations? Maybe someone help how to start? Maybe there is any library for it? Any hints?
