Make attachment mandatory onSubmit in Portal

[booher04]

Having trouble getting the below script to work.  I'm trying to have an attachment be mandatory on the portal when submitting a catalog item request.  It will only be required if a variable is 'yes'.  I think the issue may be that I am not using cart layout. I do get a java console error when I click submit but the form submits anyhow. 

function onSubmit() {

if (g_form.getValue('multiple_user_access_request') == 'yes'){ //Checks whether the variable value is 'yes'

var cat_id = gel('sysparm_item_guid').value;

var gr = new GlideRecord("sys_attachment");

gr.addQuery("table_name", "sc_req_item");

gr.addQuery("table_sys_id", cat_id);

gr.query();

if (!gr.next()) {

alert("Attachment is required in order to submit.");

return false;
}
}

}

Hi there,

Assuming this is for a Catalog Item on the Service Portal:

To perform an onSubmit check if an attachment is attached, you could have an onSubmit Catalog Client Script like:

function onSubmit() {
  
	if(g_form.getValue('multiple_user_access_request') == 'yes') && this.document.getElementsByClassName('get-attachment').length == 0) {
		g_form.addErrorMessage(getMessage('attachment_is_mandatory'));

		return false;
	}	
   
}

If my answer helped you in any way, please then mark it as helpful.

Kind regards,
Mark
