Sending User Multi Select Values to RPG program

[nnavarrete]

Hello,
I have a field within a Form widget that has been transformed to a multi-select dropdown. Is there a method that will allow me to receive all the options selected in my backend RPG program? I am thinking something similar to GetFormChar. Thanks!

You would still use GetFormChar. However, the returned value will be an array: ["Value1","Value2","Value3"].

We can then use the vvJson procedures to extract each element.

d lChar           s           5000a
d lValue          s            128a
d lArrayPtr       s               *
d lCount          s              3 0
d lIndex          s                  like(lCount)          
 /free
  lChar     = GetFormChar('MY_FIELD');
  lArrayPtr = vvJson_parse(%addr(lChar)); // parse string into object
  lCount    = vvJsona_size(lArrayPtr);   // determine # elements
  for lIndex = 1 to lCount;              // loop through each element
    lValue = %str(vvJsona_getString(lArrayPtr
                                   :lIndex-1));
  endfor;
 /end-free
