Restrict submit if there are no attachments attached on the form in Custom Portal

[satya30]

Hi All,

In the form: If the url value is empty it should check if there are any attachments attached. if attachment is there it should submit otherwise it should not submit instead throw an error message.

In the below script that I am writing:

g_form.getUniqueValue() is not giving the record value that is going to be created.( It is giving me sys_id of constant record all the time).

Client Script:

function onSubmit() {
    var url = g_form.getValue('file_upload_url');
    g_form.addInfoMessage(url);

    if (!url) {
        g_form.addInfoMessage("alert2:");

        var sysid = g_form.getUniqueValue();
        alert("Check id = " + sysid);
        var gr = new GlideAjax("sn_customerservice.getAttachmentCount");
		gr.addParam('sysparm_name', 'getCount');
        gr.addParam("sys_attach", sysid);
        gr.getXMLAnswer(validate);

    } 
    function validate(answer) {
        g_form.addInfoMessage("answer" + answer);

        if (answer == false || answer == 'false') {
            alert('Please attach Photo(s) or add URL to proceed with the submission of your request');
            return false;
        } else {
            return true;
        }
    }
}

Script Include:

var getAttachmentCount = Class.create();
getAttachmentCount.prototype = Object.extendsObject(global.AbstractAjaxProcessor, {


    getCount: function() {
        var valid = false;
        var attachId = this.getParameter("sys_attach");
		gs.info("Harika"+attachId);
        var gr = new GlideRecord("sys_attachment");
        gr.addQuery('table_sys_id', attachId);
		gr.query();
		if(gr.getRowCount()>1){
        if (gr.next()) {
			gs.info("Harika"+gr.table_sys_id);
            valid = true;
        }
		}
        return valid;
    },
    type: 'getAttachmentCount'
});

Please help me on how should I achieve this requirement.

Thank you
