Installable with the Extension Manager

Description

This application provides an Attachment Selector, which is a picker associated with XObject properties of type String, offering a friendly UI for selecting one of the document's attachments and updating the property's value with that attachment's name.

In view mode, it displays the name of the attachment or the corresponding image if the attachment is an image and the macro is parametrized to display images, possibly surrounded by a link to the attachment if the link parameter is set to true.
In edit mode, it also generates a button that triggers the actual selector. The selector consists of an attachment gallery listing the attachments of the current document that are accepted by the property (see the filter parameter), and giving the possibility to upload new attachments, to select, replace or delete existing attachments, and to empty the property value.

Usage examples

{{attachmentSelector classname="Sandbox.Demo" property="attachedDocument" filter="pdf,odt"/}}

{{attachmentSelector classname="Sandbox.Demo" property="attachedImage" filter="png,jpg,gif"
displayImage="true"/}}

{{attachmentSelector classname="XWiki.XWikiUsers" property="avatar" savemode="direct"
displayImage="true"  width="120" link="true" filter="png,jpg,gif"
defaultValue="[email protected]"/}}

{{attachmentSelector classname="Sandbox.Demo" property="attachedDocument" savemode="direct"
displayImage="true"  width="120" link="true" filter="pdf,odt"
defaultValue="[email protected]"/}}

Parameters

  • classname (mandatory): The full name of the document holding the XClass that contains the property associated with this picker.
  • property (mandatory): The name of the property associated with the picker.
  • object: The identifier (number) of the object for which the property is displayed by this picker. If missing, the first instance of the class given by the parameter classname found in the document will be considered.
  • cssClass: A CSS class for the element surrounding the displayed property value.
  • savemode: States how the property is updated. Accepted values: form (default) meaning that the selected value is stored in an input that will be saved via an external form; direct means that the picker is responsible with updating the property value.
  • buttontext: Text of the button that triggers the picker. Defaults to $services.localization.render('xe.attachmentSelector.selectFile').
  • defaultValue: What attachment is displayed in view mode if the property is empty. Should either be empty or in the form of a wiki attachment reference (e.g.: attachment.txt, [email protected]).
  • filter: Comma separated list of file extensions accepted by the property (to become a comma separated list of mimetypes when XWiki will use HTML5). All files are accepted if this parameter is empty.
  • displayImage: States whether images are displayed or just their name is printed like for other attachments. Possible values: true, false (default).
  • width: The width of the displayed image, only taken into account if displayImage="true".
  • height: The height of the displayed image, only taken into account if displayImage="true".
  • alternateText: The alternate text (alt attribute) of the displayed image, only taken into account if displayImage="true".
  • link: States whether a link to the attachment is associated in view mode with the displayed attachment name/image. Possible values: true, false (default).
  • targetdocname: An optional reference to a document to use as the source (and target) for the attachments to display. By default the current document is used.
  • versionSummary: Whether to allow the user to enter a version summary that will be recorded in the history. An automatic message is used when no version summary is provided or if the version summary input is not displayed. Possible values: true, false (default). Since 9.5RC1.
