Compact code for field validation

This piece of code helps reduce the number of lines of code that are usually written to validate fields on a form.

These steps and this piece of code helps reduce the number of lines of code that are usually written to validate fields on a form.

  1. Create a hidden field multi-value "fieldlist" on the form and list all of the fields that need to be validated in the format of <Field Name>"~"<Field Label>".

    Example: "IR_txIA~Inventory Admin":"IR_txItem~Item":"IR_Justify~Justification";

  2. Declare FieldItem as notesitem , FieldName as string and FieldLabel as string.

  3. Create a function named Validation and copy the following code:
 
Function Validation 
 Validation=False
 Set  fielditem=doc.getfirstitem("flist") 
 Forall v In fielditem.Values
  fieldname=Strtoken(v, "~", 1)
  fieldLabel=Strtoken(v, "~", 2)
  If Trim(uidoc.fieldgettext(fieldname))=
"" Then 
   Call ValidationMessage(uidoc,
fieldName, fieldLabel) 
   Exit Function   
  End If
 End Forall
 
 validation=True
End Function

That's all!

Even if there are n number of fields on the form, only these few lines of code are required to validate all of them . In my case, all of the fields are text; for other data types, the code can be enhanced on the same logic.
