Wikidotのデータフォームを使用すると、簡単なアプリケーションをあなたのWikidotサイトに組み込むことができます。通常のWikiページは構造化されていないテキストを保持しています。データフォームを備えたWikiページは構造化されたデータ("フィールド")を保持します。多くの場合、構造化されたデータの方が編集しやすく、理解しやすく、作業しやすいです。

データフォームの機能は新しく、急速に進化しています。ご意見がありましたら、このフォーラムに参加してご相談ください。

データフォームの使用例

ここでは、データフォームが単純なwikiページよりもうまく機能する場合の例をいくつか紹介します。

• 論文のための参考文献を集めており、それぞれの参考文献について、タイトル、著者、ISBN、発行日、出版社、言語を記録したいと思っています。1つのデータに対して1つのフィールドを持つデータフォームを使えば、どんな形式の参考文献リストでも簡単に作成できます。

• クラブの会員を整理していますが、各会員の名前やメールアドレスなどのページが欲しいです。データフォームを使えば、メールアドレスなどのフィールドを抽出して、全員にニュースレターを送ることができます。

• ビデオゲームのコレクションをカタログ化しています。データフォームを使うことで、ゲームをコンソール別、パブリッシャー別などで検索できます。

新しいデータフォームの作成方法

Wikidotではページはカテゴリに格納されますが、データフォームを使用すると、各ページは1つの「オブジェクト」になります。1つのカテゴリには1つのデータフォームを持つことができ、そのカテゴリ内のすべてのページに適用されます。

新しいデータフォームを作成するには、カテゴリの_templateページを編集し、[[form]]セクションを追加します。 いくつかのフィールドを表示するシンプルなフォームを以下に示します。

[[form]]
fields:
 name:
 label: Member name
 email:
 label: Email address
 get-newsletter:
 label: Get newsletter?
 values:
 0: "No"
 1: "Yes"
 default: 1
[[/form]]

[[form]]セクションを定義すると、カテゴリー内のすべてのページが通常のページエディターの代わりにフォームを表示するようになります。

フォームデータの使用方法

The simplest way to use form data is to let people enter, browse, and improve it, just as for normal wiki pages. You can configure category permissions exactly as for normal pages so that, for example, only the author of a page can edit it. If you look at the page source you will see that the form data is stored in a format that looks a bit like the form definition.

You can also use form data in lists and reports, using the ListPages module:

These properties can be used in live templates to give greater control over the presentation of the data form on a page.

Is %%form_data{member-name}%% subscribed to the newsletter? %%form_data{newsletter}%%
====
[[form]]
fields:
 member-name:
 label: Member name
 newsletter:
 label: Subscribe to newsletter?
 type: select
 values:
 1: "Yes"
 2: "No"
[[/form]]

The Pagepath concept

Wikidot data forms have a unique concept, the Page Tree and pagepath, which is a way of organizing data. Imagine your video games collection, and you want to store for each game the genre of game. Game genres form a tree:

• _root
  • Adventure
  • Action
    • Simulation
      • Driving
      • Other
    • Combat
  • Sports
    • Football
    • Racing

where each part of the tree is a wiki page. Imagine this tree is held in a category called genre:. Now we can use parent links to attach Racing to Sports, and Driving to Simulation to Action.

The Wikidot data form system makes it easy to navigate, and edit such a tree. You define a 'pagepath' field and tell it to use the genre: category. Then users can chose any genre, making the tree more precise (if the genre: category lets them create and edit pages) over time:

[[form]]
fields:
 genre:
 label: Game genre
 type: pagepath
 category: genre
[[/form]]

A page tree is always anchored to a page called _root that Wikidot creates automatically when you start using a page tree in forms.

Deleting a form

If you wish to remove a form from the _template, do not simply comment it out. Either delete it completely or change [[form]] to something like [[x-form]]. Otherwise the form will continue to be used.

Reference

The form definition is made in YAML, which is a simple structured markup language. A _template may have a single form. The form starts and ends with [[form]] and [[/form]] as for code blocks. Within those tags, we describe the form using YAML:

[[form]]
fields: # This is always required at the start
 name-of-the-field: # Use a valid YAML name
 label: Label # This is what the user sees
 type: type-of-field # The field types
 property: value... # Depending on the field type
[[/form]]

The default field type is 'text', unless you specify one or more values, in which case it defaults to 'select'.

Field Properties

Properties that apply to all field types

The 'label' property

If you specify a 'label' property then the field gets that text in the left column, or before the field for joined fields. If you do not specify a label then the field has an empty space in the left column, or is squashed up after the previous field, for joined fields. For example:

[[form]]
fields:
 address-line-1:
 label: Address
 width: 30
 address-line-2:
 width: 30
 address-line-3:
 width: 30
[[/form]]

The 'join' property

If you specify 'join: true' then the field is placed after the previous field, if any. This property has no effect if the field is the first in the form. For example:

[[form]]
fields:
 city:
 label: City
 width: 20
 postcode:
 label: Postcode
 width: 8
 join: true
[[/form]]

The 'before' property

Provides a string of plain text that displays before the field value

[[form]]
fields:
 phone:
 label: Phone
 width: 10
 before: +(1)
[[/form]]

The 'after' property

Pprovides a string of plain text that displays after the field value

[[form]]
fields:
 speed:
 label: Car speed
 width: 4
 after: mph
[[/form]]

Properties that apply to specific field types

There are additional properties that only apply to specific field types. These are documented below with the field type(s) they apply to.

Field Types

The 'text' field type

Defines a text or text box field. Allows 'width' and 'height' as properties. If you don't specify a height you get a normal 1-line text field. If you do specify it, you get a text box. For example:

[[form]]
fields:
 name:
 label: Your name
 type: text
 width: 30
 comment:
 label: Your comment
 type: text
 width: 50
 height: 3
 email:
 label: email address
 match: /^[_a-zA-Z0-9\-\+]+(\.[_a-zA-Z0-9-]+)*@[a-zA-Z0-9-]+(\.[a-zA-Z0-9-]+)+$/
[[/form]]

The specific properties you can use on a text field:

• width: specifies the visible field width in columns (fixed spaced characters, more or less).
• height: specifies the field height in rows, 1 is normal text field, 2 or more is a text box.
• match: specifies a regular expression that the field value must match.
• match-error: specifies a custom error message.
• hint: provides a string of text that is displayed in the field when empty.
• default: defines a default value for the field shown on new pages.

The 'select' field type

Defines a multi-value selection field. Requires a set of values. If you specify two to four values, you get a horizontal radio field. If you specify five or more values, you get a drop-down select field. For example:

[[form]]
fields:
 your-mood:
 label: Your mood
 type: select
 values:
 1: manic
 2: happy
 3: calm
 4: down
 5: depressed
 her-mood:
 label: Her mood
 type: select
 values:
 1: silent
 2: chatty
[[/form]]

The specific properties you can use on a select field:

• default: defines a default value for the field shown on new pages.

The 'checkbox' field type

Defines a checkbox field, stored in the form data as 0 or 1. For example:

[[form]]
fields:
 onions:
 label: Do you want onions?
 type: checkbox
 salami:
 label: How about extra salami?
 type: checkbox
 default: 1
[[/form]]

The specific properties you can use on a checkbox field:

• default: defines a default value for the field shown on new pages.

The 'pagepath' field type

Lets the user create and select from a page within a page tree; the 'path' is the list of all parents plus that page. It is visualized as page / page / page / page with at each level, the option of viewing that page, changing the page, or adding a new child. This does not affect the actual page parent, and a form can have many pagepath fields. The pagepath field value is stored as a page full name. Hidden pages are invisible to users when selecting and navigating the page tree.

[[form]]
fields:
 genre:
 label: Game genre
 type: pagepath
 category: genre
[[/form]]

The specific properties you can use on a pagepath field:

• category: specifies the category that holds the page tree.
• default: defines a default value for the field shown on new pages.

The 'hidden' field type

Adds data to the form that the user cannot see or edit. Takes no space visually. This is for putting data into the page so that data can be used later. The value of the field is defined by the 'value' property.

[[form]]
fields:
 version:
 type: hidden
 value: 1.0
[[/form]]

The specific properties you can use on a hidden field:

• value: sets the value of the field

The 'wiki' field type

Works like text but lets the user enter a block of wiki text. Note: wiki text is not allowed in normal text fields, it must be enabled explicitly with wiki fields.

[[form]]
fields:
 version:
 label: Fancy text field
 type: wiki
[[/form]]

The 'static' field type

This shows uneditable wiki text and lets the form designer add text and formatting to the form. Static fields are not stored in the page. Static fields get their value from the 'value' property.

[[form]]
fields:
 version:
 type: static
 value: Non-storable field with with **bold**, //strike// and __underline__.
[[/form]]

The specific properties you can use on a static field:

• value: sets the value of the field

The 'file' field type

This lets the user upload files directly from the data form. It is displayed as a link to the file.

Files are not uploaded to the same page. Instead, a separate page is created for each file in a different category, 'file' by default.

[[form]]
fields:
 document:
 type: file
 label: Upload document
 category: alternative-category
[[/form]]

The specific properties you can use on a file field:

• category: specifies the category that the page will be created in ('file' category if not specified), and the uploaded file is attached to this page.

The 'url' field type

This lets the user enter URLs. This is displayed as a link.

[[form]]
fields:
 info_link:
 type: url
 default: ftp://example.com/files/
 match-error: Custom error msg.
 required: true
 default-schema: ftp://
[[/form]]

The specific properties you can use on a url field:

• width: specifies the visible field width in columns (fixed spaced characters, more or less).
• default: defines a default value for the field shown on new pages.
• default-schema: define a default schema for URL ('http://' if not specified).
• match-error: specifies a custom error message.
• required: specifies if the field is mandatory [true/false] ('false' if not specified).

The 'password' field type

This lets the user enter masked text. To the user, each character they type is replaced by an asterisk ( * ).

[[form]]
fields:
 pass:
 type: password
[[/form]]

Important: Entered text is not encrypted, you can always read it in page source.

CSS Styling

You can modify the look and feel of your data forms using CSS (either per-site, or per page using the CSS module. This is the CSS model for data forms:

• table
  class: form-table
  • tr
    class: form-row
    • td
      class: form-labels
      • span
        class: form-label
    • td
      class: form-values
      • span/div (div for wiki and static)
        class: form-value field-{name}
        class': form-error (added to field while save when there is matching error)
        • label (auto-added to form when field have defined hint property)
          class: form-hinted
        • {field}
          class: form-{type}
        • span
          class: form-message

Symbols:

{name} - name of the field
{type} - type of the field (text, select, pagepath etc.)
