Select Options Fieldtype (FieldtypeOptions)

The Options Fieldtype provides single and multi choice selectable options in ProcessWire, as an alternative to using Page fields.

About the Options Fieldtype

While we usually recommend using the Page Fieldtype for selectable options, this Options Fieldtype provides a convenient alternative for when the selectable options will not benefit from being pages, or when a speedy definition process outweighs the benefits of using pages. Like with the Page Fieldtype, you can define what type of input should be used with the field settings. The input type can be any core or 3rd party Inputfield that extends ProcessWire’s InputfieldSelect module. For core Inputfields, this includes: Single Select, Multiple Select, Checkboxes, Radio Buttons, and AsmSelect (a sortable multi-select).

Options are stored in a relational database normalized manner, ensuring that changes to existing options apply across existing selections.

The Options Fieldtype was added to the core in ProcessWire 2.5.17.

Options Administration

Creating an Options field

  1. Confim that you are running ProcessWire 2.5.17 or newer.
  2. Install the Select Options Fieldtype module, if it is not already installed. Do this by going to Modules > Core > Fieldtype > Select Options (or from the drop-down menus: Modules > Install > FieldtypeOptions). If you don’t see it, you may need to first click on Modules > Refresh, and try again.
  3. Create a new field (Setup > Fields > Add New) and choose “Options” as the type.
  4. After creating the field, click to the Details tab, where you can define your options.

Defining options

You can define options on the Details tab when editing an Options field (Setup > Fields > your field). Options are defined in a multi-line text box, where each line represents one option. You may type or paste in a list of options (like a list of countries for example, 1 per line) and save.

Once an option exists in the database, it is assigned an ID number. When selected options are saved on a page, the ID number [for each option] is stored rather than the option title or value. This enables you to go back and later modify options without breaking existing selections on a page. However, it does require that that the assigned ID number always remain with the option.

In addition, these ID numbers enable mutli-language support by connecting an option in one language with a translation in another language. Please note that these ID numbers need not symbolize anything about your option title or value, and are not typically used for anything on the front-end of your site.

Adding New Options

Enter the text of each new option on a new line anywhere in the existing options. You may omit the ID number as one will be automatically assigned after you save. Once assigned, you should never change this ID number, but you can change the title (or value) as much as you like.

While we recommend letting the Options Fieldtype assign unique ID numbers for you, you may optionally assign your own. To do this, specify 123=title when adding a new option, where 123 is the ID number you wish to assign and title is the title text for your option. If you need separate “value” and “title” properties for each option, see the last section in these notes.

Moving or Sorting Options

Copy entire line(s), including ID number, and paste wherever you want them to go.

Editing or Renaming Options

Modify the option title or value as you would like, ensuring that the original ID number remains connected with the option.

Deleting Options

Delete the entire lines containing the options that you want to delete. You will be asked to confirm the deletion after you submit the form. The option will not be deleted until you click the box to confirm and submit the form again. Note that this also deletes any selections for that option in the database.

If using multi-language options, deleting the option in the default language deletes it for all languages, and deleting an option in a non-default language only deletes the translation.

Multi-Language: Translating Options

Multi-language support with options requires that you have the LanguageSupportFields module installed (Modules > Core > Language > Language Support Fields).

Define your options in the default language and save, before defining them in other languages. Copy the options you want to translate from the default language tab to the other language tab. Paste in and translate the titles (and/or values). Untranslated options inherit the default language title and value. If using separate option values (as described in the next section) your translation does not need to include the “value” portion unless you want it to.

Separate Option Values

By default only titles are kept with each option. If you want to maintain a separate value and title, enter your option in the format value|title (for new options) or 123=value|title (for existing options that already have an ID assigned). The text for value and title will be kept as separate $option->value and $option->title properties from the API. These properties can also be independently queried to find pages from the API.

Options API

Outputting selected options on a page

You output options in exactly the same way that you would page titles. For our example, lets assume you created an Options field called “countries” and you wanted to output an HTML list of those countries:

If Options field only supports 1 selection, the above example would still work. However, you can also do this:

There is no distinction between single-value and multi-value options at the API level. You can simply choose to treat it as a single or multi-value field as you see fit. This works because when you access the title (or other) property from the field, it simply gives you the value for that property from the first item.

Manipulating options on a page from the API

The value of your Options field (i.e. $page->countries ) is a WireArray, and can be manipulated using any of the methods supported by WireArray. Once manipulated, you would either save the page they live on, or save the page field, i.e. $page->save (‘countries’);

Before manipulation options on a page, always make sure that output formatting is OFF first:

If working with an Options field that supports a single selected value, you can set it directly as the title:

For a multi-value Options field, set it as an array…

…or a pipe “|” separated string:

The above examples demonstrate setting the value by the option’s title property. You can also set it from the option’s id property, the value property, or directly with SelectableOption or SelectableOptionArray objects. If setting with the value property, note that the title property is considered before the value property (if there are any conflicts).

A note about numeric titles: Any time you set from a numeric value, it is assumed to be the id property. If your situation involves options that have a numeric title, this is someting to consider, as you’ll likely want to stick to setting the options by id in order to avoid confusion. Or, you can use one of the methods described below to retrieve all options and determine which ones you need. In particular, see the “Getting the id property of an option when you only know the title” section below.

Getting all possible options

This retrieves all possible options for the field, regardless of whether they are selected or not (there is no page involved here).

Getting the id property of an option when you only know the title:

The following code examples build upon the previous example (getting all possible options), so make sure to include that first.

If you need to pull multiple options out of a set:

You can use these values (objects) you pulled from $all_options to set the value of your options field:

5 Отображение Seed Starter Data

Первое, что покажет наша страница /WEB-INF/templates/seedstartermng.html, — это список с начальными стартовыми данными, которые в данный момент сохранены. Для этого нам потребуются некоторые внешние сообщения, а также некоторая работа выражений для атрибутов модели. Как это:

Здесь много чего посмотреть. Давайте посмотрим на каждый фрагмент отдельно.

Прежде всего, этот раздел будет отображаться только при наличии seed стартеров. Мы достигаем этого с помощью атрибута th:never и функции #lists.isEmpty(. ).

Обратите внимание, что все служебные объекты, такие как #lists, доступны в выражениях Spring EL так же, как и в выражениях OGNL в стандартном диалекте.

Следующее, что нужно увидеть, это много интернационализированных (экстернализованных) текстов, таких как:

List of Seed Starters

Это приложение Spring MVC, мы уже определили bean-компонент MessageSource в нашей конфигурации Spring (объекты MessageSource являются стандартным способом управления внешними текстами в Spring MVC):

… и это свойство basename указывает, что в нашем пути к классам у нас будут файлы, такие как Messages_es.properties или Messages_en.properties. Давайте посмотрим на испанскую версию:

В первом столбце таблицы мы покажем дату, когда был подготовлен стартер. Но мы покажем, что он отформатирован так, как мы определили в нашем DateFormatter. Для этого мы будем использовать синтаксис двойной скобки ($<<. >>), который будет автоматически применять сервис преобразования Spring, в том числе DateFormatter, который мы зарегистрировали при настройке.

Далее показано, покрыт ли начальный контейнер seed starter или нет, путем преобразования значения свойства булевого покрытого бина в интернационализированное «да» или «нет» с буквальным выражением подстановки:

Теперь мы должны показать тип начального seed starter контейнера. Тип представляет собой java-перечисление с двумя значениями (WOOD и PLASTIC), и поэтому мы определили два свойства в нашем файле Messages с именами seedstarter.type.WOOD и seedstarter.type.PLASTIC.

Но чтобы получить интернационализированные имена типов, нам нужно добавить seedstarter.type. префикс к значению enum с помощью выражения, результат которого мы затем будем использовать в качестве ключа сообщения:

Самая сложная часть этого списка — колонка фич. В нем мы хотим отобразить все функции нашего контейнера, которые представлены в виде массива перечислений Feature, разделенных запятыми. Как «Электрическое отопление, газон».

Обратите внимание, что это особенно сложно, потому что эти значения перечисления также должны быть выведены, как мы делали с Types. Поток вывода следующий:

  • Подставьте соответствующий префикс ко всем элементам массива фич.
  • Получите внешние сообщения, соответствующие всем ключам из шага 1.
  • Присоедините все сообщения, полученные на шаге 2, используя запятую в качестве разделителя.

Для этого мы создаем следующий код:

Последний столбец нашего списка на самом деле будет довольно простым. Даже если у него есть вложенная таблица для отображения содержимого каждой строки в контейнере:

6 Создание Форм

6.1 Обработка командного объекта

Объект команды — это имя, которое Spring MVC дает бинам поддержки форм, то есть объектам, которые моделируют поля формы и предоставляют методы получения и установки, которые будут использоваться платформой для установления и получения значений, введенных пользователем в браузере.

Thymeleaf требует, чтобы вы указали объект команды, используя атрибут th:object в вашем теге

Это согласуется с другим использованием th:object, но на самом деле этот конкретный сценарий добавляет некоторые ограничения для правильной интеграции с инфраструктурой Spring MVC:

Customer A lookup field that you can use to specify a customer, which can be an account or contact.

MultiSelect Option Set

You can customize forms (main, quick create, and quick view) and email templates by adding multi-select fields. When you add a Multi-Select Option Set field, you can specify multiple values that will be available for users to select. When users fill out the form they can select one, multiple, or all the values displayed in a drop-down list.

For example, if an organization operates in multiple areas or countries, you can include multiple locations or countries in an ‘Area of operation’ field. A user can then select one or more locations from the list of available values.

Multi-select option set is only available in read-only grids, editable grids, and forms. Multi-select option set is not supported in:

  • Workflows, Actions, Dialogs, Roll Ups, charts, and Calc fields.
  • Reports, SLA, and Routing Rule.

Multi-select fields are supported in the following types of forms:

Form Type Availability
Turbo form Yes
Refresh form Read-only (field will available but cannot be edited)
Legacy form No
Bulk Edit form No

You can use global option sets that are defined in your organization to configure values for the multi-select option sets. For Use Existing Option Set, select Yes, and then choose an option set from the Option Set drop-down list. Also, you can perform the following action on the global option set without leaving the field creation dialog box:

Select Edit to edit the global option set.

You can only edit a global option set if Customizable is True.

Select New to create a global option set.

Customer field

In previous releases of Dynamics 365 Customer Engagement (on-premises), several out-of-the-box entities such as the Case, Lead, and Opportunity entities, included a special kind of lookup field that represented a customer. Using this lookup field you could choose between two entities: Account or Contact. With this new capability, you can add the Customer field to any system or custom entity. You can use the Customer field in more entities to track the customer’s information in the same way you’ve used the Customer field in the Case, Lead, and Opportunity entities.

Let’s look at the following business scenario. Your company is an insurance provider. You use Dynamics 365 Customer Engagement (on-premises) to manage your customer interactions and standardize business processes. It’s important for you to know if a recipient of policies or claims is an individual or a company. To address this business requirement, you can create two custom entities: Policies and Claims. To get and track the customer information you want, add the Customer lookup field to the Policies entity and the Claims entity, by using the new Customer field capability.

Single line of text format options

The following table provides information about the format options for single line of text fields.

Format Option Description
Email The text provides a mailto link to open the user’s email application.
Text This option simply displays text.
Text Area This format option can be used to display multiple lines of text. But with a limit of 4000 characters, the Multiple Lines of Text field is a better choice if large amounts of text are expected.
URL The text provides a hyperlink to open the page specified. Any text that does not begin with a valid protocol will have “https://” prepended to it.

Only HTTP, HTTPS, FTP , FTPS, ONENOTE and TEL protocols are allowed in this field.

Ticker Symbol For most languages, the text will be enabled as a link to open the MSN Money website to show details about the stock price represented by the ticker symbol.

For certain East Asian languages the window will open Bing search results for the ticker symbol.

Phone In the web application, fields will be click-enabled to initiate calls using either Skype or Lync if a client for either is installed on your computer. The telephony provider choice is at the bottom of the General tab of System Settings.

For Dynamics 365 for tablets, Skype is the only available telephony provider.

More information: Video: Dynamics CRM – Phone Number Format Important: Lync has been rebranded as Skype for Business. Currently, you’ll still see references to “Lync” in Dynamics 365 for Customer Engagement apps, but Dynamics 365 for Customer Engagement apps will work with Skype for Business.

Whole number format options

The following table provides information about the format options for whole number fields.

Format Option Description
None This option simply displays a number.
Duration This format option can be used to display a list of duration options. But the data stored in the database is always a number of minutes. The field looks like a drop-down list and provides suggested options like 1 minute, 15 minutes, 30 minutes all the way up to 3 days. People can choose these options. However, people can also just type in a number of minutes and it resolves to that period of time. For example, type in 60 and it resolves to 1 hour. Or they can enter “1 hour” or “2 days” and it will resolve to display that time.

The duration must be entered in the following format: “x minutes”, “x hours” or “x days”. Hours and days can also be entered using decimals, for example, “x.x hours” or “x.x days”.

NOTE: Values must be expressible in minutes, sub-minute values will be rounded to the nearest minute.

Time Zone This option displays a select list of time zones such as (GMT-12:00) International Date Line West and (GMT-08:00) Pacific Time (US & Canada). Each of these zones is stored as a number. For example, for the time zone (GMT-08:00) Pacific Time (US & Canada), the TimeZoneCode is 4. More information: TimeZoneCode Class (Sdk Assembly)
Language This option displays a list of the languages provisioned for your organization. The values are displayed as a drop-down list of language names, but the data is stored as a number using LCID codes. Language codes are four-digit or five-digit locale IDs. Valid locale ID values can be found at Locale ID (LCID) Chart).

Using the right type of number

When choosing the correct type of number field to use, the choice to use a Whole Number or Currency type should be pretty straightforward. The choice between using Floating Point or Decimal numbers requires more thought.

Decimal numbers are stored in the database exactly as specified. Floating point numbers store an extremely close approximation of the value. Why choose extremely close approximation when you can have the exact value? The answer is that you get different system performance.

Use decimals when you need to provide reports that require very accurate calculations, or if you typically use queries that look for values that are equal or not equal to another value.

Use floating point numbers when you store data that represents fractions or values that you will typically query comparing to another value using greater than or less than operators. In most cases, the difference between decimal and float isn’t noticeable. Unless you require the most accurate possible calculations, floating point numbers should work for you.

Using currency fields

Currency fields allow for an organization to configure multiple currencies that can be used for records in the organization. When organizations have multiple currencies, they typically want to be able to perform calculations to provide values using their base currency. When you add a currency field to an entity that has no other currency fields, two additional fields are added:

A lookup field called Currency that you can set to any active currency configured for your organization. You can configure multiple active currencies for your organization in Settings > Business Management > Currencies. There you can specify the currency and an exchange rate with the base currency set for your organization. If you have multiple active currencies, you can add the currency field to the form and allow people to specify which currency should be applied to money values for this record. This will change the currency symbol that is shown for the currency fields in the form.

Individuals can also change their personal options to select a default currency for the records they create.

A decimal field called Exchange Rate that provides the exchange rate for a selected currency associated with the entity with respect to the base currency. If this field is added to the form, people can see the value, but they can’t edit it. The exchange rate is stored with the currency.

For each currency field you add, another currency field is added with the prefix “_Base” on the name. This field stores the calculation of the value of the currency field you added and the base currency. Again, if this field is added to the form, it can’t be edited.

When you configure a currency field you can choose the precision value. There are essentially three options as shown in the following table.

Option Description
Pricing Decimal Precision This is a single organization precision to be used for prices found in Settings >Administration >System Settings >General Tab.
Currency Precision This option applies the precision defined for the currency in the record.
Specific precision values 0 – 4 These settings allow for defining a specific set precision.

Different types of lookups

When you create a new lookup field you are creating a new Many-to-One (N:1) entity relationship between the entity you’re working with and the Target Record Type defined for the lookup. There are additional configuration options for this relationship that are described in Creating and editing entity relationships. But all custom lookups can only allow for a reference to a single record for a single target record type.

However, you should be aware that not every lookup behaves this way. There are several different types of system lookups as shown here.

Lookup type Description
Simple Allows for a single reference to a specific entity. All custom lookups are this type.
Customer Allows for a single reference to either an account or a contact record. These lookups are available for the Opportunity, Case, Quote, Order, and Invoice entities. These entities also have separate Account and Contact lookups that you can use if your customers are always one type. Or you can include both instead of using the Customer lookup.
Owner Allows for a single reference to either a team or a user record. All team or user-owned entities have one of these.
PartyList Allows for multiple references to multiple entities. These lookups are found on the Email entity To and Cc fields. They’re also used in the Phone and Appointment entities.
Regarding Allows for a single reference to multiple entities. These lookups are found in the regarding field used in activities.

Image fields

Use image fields to display a single image per record in the application. Each entity can have one image field. You can add an image field to custom entities but not to system entities. The following system entities have an image field. Those marked with an asterisk are enabled by default.

Account * Article Campaign
Case Competitor * Connection
Contact * Contract Currency
Email Server Profile Goal Invoice
Lead * Mailbox Opportunity Product
Order Organization Product *
Publisher * Queue Resource *
Sales Literature Territory User*

Even though an entity has an image field, displaying that image in the application requires an additional step. In the entity definition the Primary Image field values are either [None] or Entity Image. Select Entity Image to display the image in the application. More information: Creating and editing entities

When image display is enabled for an entity, any records that don’t have an image will display a placeholder image. For example, the Lead entity:

People can choose the default image to upload a picture from their computer. Images must be less than 5120 KB and must one of the following formats:

When the image is uploaded, it will be converted to a .jpg format and all downloaded images will also use this format. If an animated .gif is uploaded, only the first frame is saved.

When an image is uploaded, it will be resized to a maximum size of 144 pixels by 144 pixels. People should resize or crop the images before they upload them so that they will display well using this size. All images are cropped to be square. If both sides of an image are smaller than 144 pixels, the image will be cropped to be a square with the dimensions of the smaller side.
