Update an existing User List Element in a Formulize form.

Overview: ‘Users’ elements provide a way for people to select from a list of users in the system. Most of the standard types of list elements can be implemented as ‘Users’ elements.

Important notes:

  • ‘Users’ elements are useful for providing lists of users, but they are also useful for setting up customized permissions, because there are other features in Formulize which can control the access to individual form entries based on whether that entry has a user selected in a ‘Users’ element.

Properties common to all ‘Users’ elements:

  • sourceGroups (optional, an array of group ids from which the users in the list should be drawn. Use the list_groups tool see a list of all the groups and their ids. Use the list_group_members tool to see a list of users who are members of a specific group. If this is not specified, or the array is empty, then all users in the system will be shown, regardless of their group membership.)

Basic examples:

  • A list of all users in the system (no properties): { }
  • A list of users from groups 3 and 6: { sourceGroups: [3, 6] }

Element: Autocomplete List of Users (autocompleteUsers)

Description: A single-line text box that provides autocomplete suggestions based on a list of users.

Properties:

  • all the common properties for ‘Users’ elements, plus:
  • allowMultipleSelections (optional, a 1/0 indicating if multiple selections should be allowed. For Autocomplete Lists of Users, the default is 0. Set to 1 to allow multiple selections.)

Example:

  • A list of users in the system, and more than one user can be selected: { sourceGroups: [], allowMultipleSelections: 1 }

Element: Listbox of Users (listboxUsers)

Description: A listbox that allows users to select one or more users from a list. In general, Listboxes provide a poor user experience. Use a Dropdown List of Users or an Autocomplete List of Users instead, unless a Listbox is specifically called for.

Properties:

  • all the common properties for ‘Users’ elements, plus:
  • allowMultipleSelections (optional, a 1/0 indicating if multiple selections should be allowed in the listbox. For Listboxes of Users, the default is 1. Set to 0 to allow only a single selection.)

Example:

  • A list of users from group 12, and more than one user can be selected: { sourceGroups: [12], allowMultipleSelections: 1 }

Element: Dropdown List of Users (selectUsers).

Description: A dropdown list where the options are the users from one or more groups, or the entire system. The user can select one choice.

Properties:

  • all the common properties for ‘Users’ elements

Properties

Property Type Required? Description
element_identifier string or integer Required
caption string Optional

Optional. The new label for the User List Element as it will now appear to users in forms.

properties object Optional

Optional. Updated configuration settings for the User List Element. The available properties depend on the element type. See the tool description for examples of what properties are needed for different element types. Use the get_form_details tool to see all the element types for the existing elements.

column_heading string Optional

Optional. The heading to use at the top of a column in lists of entries. If not specified, the caption will be used. Some captions are long and descriptive, and a shorter heading would be more appropriate for in a list of data.

help_text_for_users string Optional

Optional. A longer description or help text for the User List Element, shown to users filling out the form. This is NOT an internal notes field, this content appears as part of the element.

required boolean Optional

Optional. Whether the User List Element is required to have a value when users fill out the form. Default: false

principal_identifier boolean Optional

Optional. Whether the User List Element is the principal identifying element for entries in this form. Principal identifiers are used in various places in Formulize to represent an entry. The Principal Identifier would typically be a ‘Name’ text box or other element that unique identifies the entry. Each form can only have one Principal Identifier. If a form has a Principal Identifier, and another element is created or updated with this value set to true, the existing Principal Identifier will be replaced with the new one. Default: false.

disabled boolean Optional

Optional. Whether the User List Element element is disabled (visible but not usable) in the form. Default: false.

display boolean Optional

Optional. Whether the User List Element is displayed in the form or hidden. Default: true.

display_conditions array of object Optional

Optional. A given form entry must meet these conditions in order for this element to be displayed; otherwise it is not shown. Each condition includes an element, an operator, a value, and a ‘type’ flag indicating the logical set the condition belongs to: ‘match-all’ or ‘match-one-or-more’. Multiple match-all conditions are joined with a logical AND operator, and multiple match-one-or-more conditions are joined with a logical OR operator. Only include this property when you intend to change the conditions: omit it entirely to leave any existing conditions unchanged; provide the list of conditions to set or replace them; or provide an empty array ([]) to remove all conditions so the element is always displayed. When setting conditions based on linked elements, do not use foreign keys as values, and instead use the readable value which this tool understands automatically. Use the special value “{BLANK}” (without quotes) to match blank values.
Examples:

  • [ { “element”: “status”, “operator”: “=”, “value”: “Approved”, “type”: “match-all” } ]
  • [ { “element”: “award_value”, “operator”: “>”, “value”: “500”, “type”: “match-all” }, { “element”: “award_year”, “operator”: “=”, “value”: “2026”, “type”: “match-all” } ] Match size 40 pants OR green pants:
  • [ { “element”: “pant_size”, “operator”: “=”, “value”: “40”, “type”: “match-one-or-more” }, { “element”: “pant_color”, “operator”: “=”, “value”: “green”, “type”: “match-one-or-more” } ] Match incomplete orders that are due before today, and are going to either Canada or Mexico:
  • [ { “element”: “order_state”, “operator”: “=”, “value”: “incomplete”, “type”: “match-all” }, { “element”: “order_due_date”, “operator”: “<”, “value”: “{TODAY}”, “type”: “match-all” }, { “element”: “order_destination”, “operator”: “=”, “value”: “Canada”, “type”: “match-one-or-more” }, { “element”: “order_destination”, “operator”: “=”, “value”: “Mexico”, “type”: “match-one-or-more” } ] Do not use foreign key values with linked elements; use the readable value instead:
  • Incorrect: [ { “element”: “assigned_judge”, “operator”: “LIKE”, “value”: “509”, “type”: “match-all” } ]
  • Correct: [ { “element”: “assigned_judge”, “operator”: “LIKE”, “value”: “Wapner”, “type”: “match-all” } ]
placement string Optional

The canonical position of the element in the form. This order is used on every form screen page that this element has been added to (newly created elements are automatically added to all pages that currently have all existing elements; to add an element to a page that has only some existing elements, use the update_form_screen tool). Use “top” to make this element the first element in the form, use “bottom” to make this element the last (which is the default for new elements), or use an element handle to place this element immediately after that element (based on the live state of the form at the time of this specific request; re-fetch get_form_details first if you need to see the current element order). On updates, omit this to leave the current position unchanged.

data_type string Optional

Optional. The MariaDB data type to be used for the field in the database where this data will be stored. The system will default to text in most cases, but will set smart defaults if the type is specifically a number box or a linked element storing foreign keys, etc. Generally this does not need to be specified, but can be used if the user has specifically stated that a certain data type must be used for a given element. Valid types are: text, int(x), decimal(x,y), date, datetime, time, char(x), varchar(x). For int(x), the x is the number of digits to display in MariaDB when showing the number. For decimal(x,y), the x is the total number of digits, and y is the number of digits after the decimal point. For char(x) and varchar(x), the x is the maximum number of characters to store.
