HI EVERYONE I AM NEW WITH APPIAN ,

I AM LOOKING TO UPLOAD MULTIPLE DOCUMENTS BUT I AM STRUGGLING TO FIND A SOLUTION.

I HAVE A LIST OF DOCUMENTS ITEMS THAT I RECEIVE FROM A QUERY ( BECAUSE I NEED TO DISPLAY ON THE INTERFACE THOSE DOCUMENTS FOR THE USER TO UPLOAD , SOME TIMES THE AMOUNT OF DOCUMENTS TO DISPLAY CAN BE DIFFERENTS BASED ON WHAT THE USER CLICK IN THE INTERFACE).

NOW I LOOP THROUGH THE LIST THAT I HAVE AND CREATE A UPLOAD COMPONENT IN THE DYNAMIC WAY AND DISPLAY ON EACH LABEL OF THE COMPONENTS 'S DATA.

BUT HOW CAN I SAVE EVERY DOCUMENTS IN LOCALVARIABLE ?? tHE THING IS THAT I NEED AFTER THAT TO SAVE THOSE FILES DB , SO I CREATE A RULE INPUT DOCUMENT WITH CDT.

THERE IS A BETTER TO DOING THIS ??

Hi there,

There are 2 approaches to the problem statement.

Use one file upload field to upload multiple documents instead of creating multiple(dynamic) file upload components. But as I see the screenshots, looks like every upload field has a different label so I am not sure if you can use this approach.
Continue using a!forEach loop to render multiple file upload fields. In this, you can use local!documentList variable to generate a list of null values of the same length and then use every index of it to save to the corresponding file. I will also add a code snippet below for better understanding. And at the end, when a user submits the form, you can save that local to RI.

a!localVariables(
  local!documentList: {1,2,3,4},
  local!documentValues: a!forEach(
    items: local!documentList,
    expression: null()
    
  ),
  {
    a!forEach(
      items: local!documentList,
      expression: a!fileUploadField(
        maxSelections: 1,
        value: local!documentValues[fv!index],
        saveInto: local!documentValues[fv!index]
      )
    ),
    a!buttonLayout(
      primaryButtons: a!buttonWidget(
        label: "SUBMIT",
        saveInto: {
          a!save(
            ri!documentValues,
            local!documentValues
          )
        }
      )
    )
  }
)
