Automatically fill fields from sys_user

[Marielle Beset]

I want to create a catalog item where multiple users can be selected, and fields are automatically filled with the user_name and email fields.

My screen should look like this:

Name from table sys_user | Automatically fill with user_name | Automatically fill with email

Is this easy to make, and if so, can someone explain it to me?

Hi @Marielle Beset ,

To auto-populate fields like user_name and email from the sys_user table in a ServiceNow catalog item when multiple users are selected, you can follow these steps:

---

✅ 1. Use a List Collector Variable to Select Multiple Users

• Create a List Collector Variable:

  • Set the variable type to List Collector.

  • Reference the User [sys_user] table.

  • This allows selection of multiple users.

• Configure Display Columns:

  • Use the variable attribute ref_ac_columns=user_name,email to display user_name and email in the list.

  • This enhances the user selection experience.

---

✅ 2. Auto-Populate user_name and email Fields

• Create Additional Variables:

  • Add variables to your catalog item to hold the user_name and email values.

  • These can be of type Single Line Text or Multi Line Text, depending on your preference.

• Use a Catalog Client Script:

  • Write an onChange client script for the List Collector variable.

  • In the script, use g_form.getReference() to retrieve the selected users' records.

  • Extract the user_name and email from each record and populate the corresponding variables.

  Example Script:

function onChange(control, oldValue, newValue, isLoading) {
  if (isLoading || newValue == '') {
    return;
  }

  var userIDs = g_form.getValue('user_list'); // Replace 'user_list' with your List Collector variable name
  var userIDArray = userIDs.split(',');

  var userNames = [];
  var emails = [];

  userIDArray.forEach(function(userID) {
    g_form.getReference(userID, function(user) {
      userNames.push(user.user_name);
      emails.push(user.email);

      // After processing all users, set the values
      if (userNames.length === userIDArray.length) {
        g_form.setValue('user_names', userNames.join(', ')); // Replace 'user_names' with your variable name
        g_form.setValue('emails', emails.join(', ')); // Replace 'emails' with your variable name
      }
    });
  });
}

This script retrieves the user_name and email for each selected user and populates the respective variables.

✅ 3. Alternative: Use GlideAjax for Server-Side Processing

• Create a Script Include:

  • Define a Script Include that accepts user IDs and returns their user_name and email.

  •  

  Example Script Include:

var GetUserDetails = Class.create();
GetUserDetails.prototype = Object.extendsObject(AbstractAjaxProcessor, {
  getDetails: function() {
    var userIDs = this.getParameter('sysparm_user_ids').split(',');
    var result = [];

    var gr = new GlideRecord('sys_user');
    gr.addQuery('sys_id', 'IN', userIDs);
    gr.query();

    while (gr.next()) {
      result.push({
        user_name: gr.user_name.toString(),
        email: gr.email.toString()
      });
    }

    return JSON.stringify(result);
  }
});

Modify the Client Script:

• Use GlideAjax to call the Script Include and retrieve user details.

Example Client Script:

function onChange(control, oldValue, newValue, isLoading) {
  if (isLoading || newValue == '') {
    return;
  }

  var ga = new GlideAjax('GetUserDetails');
  ga.addParam('sysparm_name', 'getDetails');
  ga.addParam('sysparm_user_ids', newValue);
  ga.getXMLAnswer(function(response) {
    var users = JSON.parse(response);
    var userNames = users.map(function(user) { return user.user_name; });
    var emails = users.map(function(user) { return user.email; });

    g_form.setValue('user_names', userNames.join(', ')); // Replace with your variable name
    g_form.setValue('emails', emails.join(', ')); // Replace with your variable name
  });
}

By following these steps, you can create a catalog item that allows multiple user selections and automatically populates their user_name and email fields.

@Marielle Beset 

you can have a list collector type variable referring to sys_user

Then write onChange catalog client script + GlideAjax on that and fill the name and email in some multi-line text variable

sample working script here; enhance for your case

Populate Email Addresses of users selected in List Collector variable to Multi Line Text Variable
