Making an attachment mandatory in a catalog item

[SK41]

Hi,

I have a requirement to make the attachment mandatory on the catalog item. User does not use service portal, so I cannot use "mandatory checkbox" in the catalog. My requirement is to check if the user has attached the file before submitting the catalog. If not, show them error message "Please attach a file".

How can I achieve that?

Thanks!

Hi, 

I am geting below error when trying to use the above code in onSubmit client script:

onSubmit script error: TypeError: Cannot read properties of null (reading 'getElementById'):
function () { [native code] }

Could you please let me know if I am missing anything here?

My catalog item is in a scoped application and I have created a module through which the user will access the catalog.

Hi @SK41 

Please set Isolate Script to False to make the script suggested by @Anurag Tripathi  work as it requires DOM manipulation.

Thanks & Regards

It is false only, still getting the error. Could it be because of scoped application?

Do I need to create any other script as well other than onSubmit to make it work?? Right now, I have just created the onSubmit script which @Anurag Tripathi  shared.

Can you show a screenshot of your script?

Here is a sample I tested on

Hi Anurag,

I used below code in onSubmit catalog client script and it worked for me:

var count = getCurrentAttachmentNumber();

    if(count == 0){

        g_form.addErrorMessage('You must add an attachment');

        return false;

    }
