Attachment name Validation on Service portal Before Catalog Item Submission

[Natraj S]

Hello All,

We have a requirement where we have to validate the attachment name in service portal before catalog item name submission.

Example:

The attachment  name should be "variance access form.xlsx", if user is trying to attach some other attachment we have to restrict the catalog item submission.

Thanks in Advance!

@Natraj S To validate the attachment name before submitting a catalog item in the ServiceNow Service Portal, you can use a client script to check the attachment name and prevent submission if it doesn't match the expected format. Here’s a solution using a onSubmit catalog client script, something like this and remove loop if there are not multiple attachments to verify,

function onSubmit() {
var expectedFileName = "variance access form.xlsx";
var isValid = false;

// Get all attachments associated with the catalog item
var ga = new GlideAjax('AttachmentAjax');
ga.addParam('sys_id', g_form.getUniqueValue());
ga.addParam('sysparm_name', 'getAttachments');
ga.getXMLAnswer(function(response) {
var attachments = JSON.parse(response.responseXML.documentElement.getAttribute("answer"));

// Check if any attachment matches the expected file name
for (var i = 0; i < attachments.length; i++) {
if (attachments[i].file_name === expectedFileName) {
isValid = true;
break;
}
}

// If not valid, show error and prevent submission
if (!isValid) {
g_form.addErrorMessage("Please attach the correct file: " + expectedFileName);
return false;
}
});
}

Hope this will help you.
