IS IT POSSIBLE TO Upload MULTIPLE DOCUMENTS WITH DYNAMIC UPLOAD COMPONENT

Question

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
 )
 }
 )
 )
 }
)
