How to prevent submission of Catalog form for particular users?

[KS86]

Hi all,

I have 'Requested For' field on catalog form. If Requested for user is belongs to 'HR' department, I need to prevent submission of catalog form. I am using the below script. But it is not submitting form for Non HR users on portal side, but it is working in native side. Let me know what I need to fix in this script to work in both native and portal side? 

Client Script - 

var validationComplete = false;

function onSubmit() {

    if (validationComplete) {

        return true;

    }

    var gaUser = new GlideAjax('getDepartment');

    gaUser.addParam('sysparm_name', 'getUserDepartment');

    gaUser.addParam('sysparm_user', g_form.getValue('requested_for'));

    gaUser.getXMLAnswer(function(response) {

        if (response == 'false') { // User is NOT HR

            validationComplete = true;

            g_form.orderNow();

        } else { // User is HR

            g_form.addErrorMessage('Catalog submission is not allowed for HR users.');

        }

    });

    return false;

}

Script include -

var getDepartment = Class.create();

getDepartment.prototype = Object.extendsObject(AbstractAjaxProcessor, {

    getUserDepartment: function() {

        var user = this.getParameter('sysparm_user');

        var grUser = new GlideRecord('sys_user');

        grUser.addQuery('sys_id', user);

        grUser.query();

        if (grUser.next()) {

            if (grUser.department.name == "HR") {

                return true;

            } else return false;

        }

    },

    type: 'getDepartment'

});

If I use g_form.submit(), I am getting this error 'Error MessageThe g_form.submit function has no meaning on a catlog item. Perhaps you mean g_form.addToCart() or g_form.orderNow() instead' in native view. 

In portal form is not submitting only(It has to submit Non HR users)

Hi @KS86 

Using g_form.OrderNow() directly inside an onSubmit()Catalog Client Script causes an infinite loop because the method triggers the submission process all over again.

Try This:

1. Create a script onSubmit Catalog Client script

• Navigate to Service Catalog > Catalog Policy > Catalog Client Scripts > click New.
• Name: Prevent HR Submission
• UI Type: All
• Type: onSubmit
• Applies on: Check both A Catalog Item and Requested For

function onSubmit() {

    var requestedFor = g_form.getValue('requested_for');

        if (!requestedFor) {

        requestedFor = g_user.userID;

    }

    var dept = new GlideAjax('CheckDepartment');

    dept.addParam('sysparm_name', 'checkHRDept');

    dept.addParam('sysparm_user_id', requestedFor);

     dept.getXMLWait();   

    var isHR = dept.getAnswer();

    if (isHR == 'true') {

        alert('Catalog submission is not allowed for HR users.');

        return false;

    }

}

2. Create the Script Include

Navigate to System Definition > Script Includes > click New.

Name: CheckDepartment

Client callable: true

var CheckDepartment = Class.create();

CheckDepartment.prototype = Object.extendsObject(AbstractAjaxProcessor, {

    checkHRDept: function() {

        var userID = this.getParameter('sysparm_user_id');

        var userGr = new GlideRecord('sys_user');

            if (userGr.get(userID)) {

             var dept = userGr.getDisplayValue('department');

            if (dept == 'HR' ) {

                return 'true';

            }

        }

        return 'false';

    },

    type: 'CheckDepartment'

});

Hi Tanushree, using getXMLWait() in client script is not a good practice. It might issues on portal side.

But I have tried this also, It is not aborting the form submission on both cases on portal .
