How to Make Attachments Mandatory in SharePoint List?
Requirement: In a SharePoint list, make the attachment required field!
Make attachments mandatory in the SharePoint list:
While creating a Document library with metadata columns is one option, the requirement is only to make the attachments mandatory in SharePoint list forms. To make attachments mandatory in the SharePoint list, we can use simple JavaScript. Add content editor or script editor web part on “NewForm.aspx” just below SharePoint list form web part, and then place the below code in it!
JavaScript to make attachments mandatory:
Use this Javascript in script editor web part in classic experience!
<script type="text/javascript" language="javascript">
function PreSaveAction() {
if (document.getElementById('idAttachmentsRow').style.display=='none' )
{
alert('Attachment is Mandatory! Please attach Documents.');
return false ;
}
else { return true; }
}
</script>
And here is the script in action:
Form Web Parts > Default New Form > Add a Web Part > Media and Content folder > Script Editor > paste javascript there. Thanks for this!
I’ve been testing this solution all day and can’t get it to function. By loading js into a CEWP, I have been able to test simple things like getting “Hello World” to display on load. But when I switch to the above js code and attempt to submit my form without an attachment, it allows me to without the error message. What might I be missing? Thanks!
Attachments are not enabled for your list, probably?
Are you in classic experience?
