Require attachment for catalog item in Service Portal

[mspeirs]

We are preparing to make Service Portal live and going through our service catalog items to make sure everything works ok. One challenge we have is being able to require an attachment before submission. We want to do this always for some forms and conditionally on others. We were using one solution that relied on the DOM but we know that functionality is restricted in the Service Portal. I have seen some solutions but I wanted something simpler that required fewer modifications of OOB code or widgets and would be flexible and easy to reuse. What I came up with is not a perfect solution but it works for now.

We have a global UI Script with reusable functions for catalog items. It prevents having to maintain functions in multiple places and makes them available for all catalog items. Lets name this global UI Script GlobalCatalogItemFunctions. This script needs to be included in your Service Portal via the Theme. Go to Service Portal > Portals and select your portal. Then click the reference icon next to the Theme field to go to its record. There is a related list called JS Includes. Create a new one (Source: UI Script) and set the UI Script to GlobalCatalogItemFunctions. You can set the display name to that as well. Save. The functions in the UI Script will now be available for use in Catalog client scripts. This is the function I am using for getting the attachment count:

UI Script: GlobalCatalogItemFunctions

function getSCAttachmentCount() {

  var length;

  try {

  length = angular.element("#sc_cat_item").scope().attachments.length;

  } catch(e) {

  length = -1;

  }

  return length;

}

This is an onSubmit script I am using for a catalog item:

function onSubmit() {

  try { //Works in non-portal ui

  var attachments = document.getElementById('header_attachment_list_label');

  if (attachments.style.visibility == 'hidden' || attachments.style.display == 'none' ) {

  alert('You must attach the completed form before submitting this request.');

  return false;

  }

  } catch(e) { //For Service Portal

  var count = getSCAttachmentCount();

  if(count <= 0) {

  alert('You must attach the completed form before submitting this request.');

  return false;

  }

  }

}

Notice in the onSubmit script I used a try/catch block and the first part works in the full UI but not in the Service Portal. In the portal, the document.getElementById... part will not work, but our catch statement performs the method that will work in the portal by calling the getSCAttachmentCount() function which is in our included ui script. That function accesses the angular scope of the catalog item which has an array of the attachments. We just want the count so we use the length attribute. There's no guarantee this will work in the future but for now it will get the job done. It would be nice if there were a function to get attachment information out-of-the-box.

For reference:

Is it possible to require a user to add an attachment before submitting a catalog item?

I have this working great on ITEMS in the service catalog and it works like a champ...

HOWEVER i have 2 order guides where i require attachments on one of the items and this code does NOT work on an order guide... troubleshooting reveals that the line in the main function

length = angular.element("#sc_cat_item").scope().attachments.length;

does not work in an order guide based item ONLY on a stand alone item.

I did notice that if you make an attachment in the portal from a stand alone item and look at it on the attachment table it is going onto the sc_req_item table..  if OTOH you put an attachment on an item in an order guide.. and look on sys_attachment it shows it is for tablename of sc_cart_item...

any idea on how to modify the length check to work on an item in an orderguide would be GREATLY appreciated.

Same boat here for me. Doesn't work on order guide on Service Portal. Keeps asking for attachment over and over. Current workaround was to show an alert "asking" for an attachment, but no way to officially verify.

Any luck in here? I'm on the same boat too.

Mandatory attachment check is not working on order guides on service portal, keep asking for the attachments over and over and not letting to proceed further.Any help on here is greatly appreciated.

Same issue, still not working in London patch 3.

I just tried it in my personal dev instance which is on patch 1 and it works fine.  Wondering if it is a bug in patch 3.
