Merge Document Fields
This script demonstrates how to merge the values of document fields.
When you extract data from a repository, the connector can produce documents that have multiple values for a single field, for example:
#DREFIELD ATTACHMENT="attachment.txt" #DREFIELD ATTACHMENT="image.jpg" #DREFIELD ATTACHMENT="document.pdf"
This script shows how to merge the values of these fields, so that the values are contained in a single field, for example:
#DREFIELD ATTACHMENTS="attachment.txt, image.jpg, document.pdf"
Copy
function handler(config, document, params)
onefield(document,"ATTACHMENT","ATTACHMENTS")
return true;
end
function onefield(document,existingfield,newfield)
if document:hasField(existingfield) then
local values = { document:getFieldValues(existingfield) }
local newfieldvalue=""
for i,v in ipairs(values) do
if i>1 then
newfieldvalue = newfieldvalue ..", "
end
newfieldvalue = newfieldvalue..v
end
document:addField(newfield,newfieldvalue)
end
return true;
