Restrict visibility of a field on the basis of certain user_name

[rishabh31]

Dear Team,

I want to restrict the visibility/display of a field 'u_consultant' (String type field) on user records.

when the loggedin user's username startsWith 'id' or 'ID', then show (Display) 'u_consultant'

and when loggedin user's username NOT startswith NOR contains 'id' or 'ID', then HIDE 'u_consultant'

Wrote below scripts but during impersonation to users having or not having 'id' or 'ID', the user records keep displaying 'u_consultant' field i.e., Not working

Script Include;

var UserUtil1 = Class.create();
UserUtil1.prototype = {
    chkUsrID: function() {
        var userid = this.getParameter('sysparm_user');
        var result = this.newItem('check');
        var userGr = new GlideRecord('sys_user');
        userGr.addEncodedQuery('active=true^user_nameSTARTSWITHID^ORuser_nameSTARTSWITHid^sys_id=' + userid);
        userGr.query();
        if (userGr.next()) {
            result.setAttribute('check', 'yes');
        } else {
            result.setAttribute('check', 'no');
        }
    },

    type: 'UserUtil1'
};

Client Script (Above Script Include Called);

function onLoad() {
   //Type appropriate comment here, and begin script below
   var chkUsrID = new GlideAjax('UserUtil1');
   chkUsrID.addParam('sysparm_name', 'chkUsrID');
   chkUsrID.addParam('sysparm_user', g_user.userID);
   chkUsrID.getXML(getStatus);

   function getStatus(answer) {
	if (answer) {
		var result = answer.responseXML.getElementsByTagname("check");
		var check = result[0].getAttribute("check");
		if (check == 'yes'){
			g_form.setVisible('u_consultant', true);
		} else {
			g_form.setVisible('u_consultant', false);
		}
	}
   }
}

Please help to modify the script so that it will work

acl creation not allowed to us, pls help with script include and client script

[Abdulrahman1]

Be aware that users will still have access to read the field from the list view as the client script will work only in the from view.

@Abdulrahman1 I understand that part but customer wants for restrict on form view even after informed them about its limitations help with the scripts, shall be grateful

[Abdulrahman1]

I tried the below Onload client script and it's working.

function onLoad() {
   //Type appropriate comment here, and begin script below
   if(g_user.userName.startsWith("id") || g_user.userName.startsWith("ID") ){
	g_form.setVisible('u_consultant',true);
   }else{
	g_form.setVisible('u_consultant',false);
   }
}

If the given solutions don't work, you will have to do it via ACL (which is the best solution to begin with). "ACL creation not allowed to us" is no reason for not using it. Get someone that is allowed to, to create it for you.
