Abstract

With OpenCms 8 come not one but two sets of demo templates - the simple Dev Demo "Basic Template" (BT) and the more advanced "Template III" (T3) module. These modules are a versatile starting point for building custom websites.

T3 has been developed to be a solid and feature rich foundation for the creation of individual OpenCms websites. BT is limited in functionality and design, but makes a good reference for developers looking at the source code since its structure is rather simple and straightforward.

This tutorial shows examples of sites that can be built with OpenCms 8 using T3 and explain configuration options and possible extensions of this template.

This tutorial goes into details of the code structure and VFS layout used for T3, as many "best practices" learned by Alkacon have been used in this template module. It shows why T3 is a good starting point for development of custom websites.

Functions of T3 get compared to BT, to point out areas in which design and functionality requirements can lead to certain development decisions.

Template III and content modules

Demo Modules

The OpenCms 8 Template III frontend features the following presets:

Main Navigation
Left Navigation
Breadcrumb Navigation
Configurable Layout

There is no dependency between the Template III module (com.alkacon.opencms.v8.template3) and the Template III resource types.

The following resource types are available in Template III as separate modules:

OpenCms 8 Article
OpenCms 8 News
OpenCms 8 Event
OpenCms 8 List
OpenCms 8 Login
OpenCms 8 Search
OpenCms 8 Twitter

OpenCms 8 Template III

The OpenCms 8 Template III features 3 well-known navigation types:

Main Navigation
Left Navigation
Breadcrumb Navigation

Those 3 navigation types are pre-configured in separate JSPs within the '/elements/menu/' subfolder of the Template III module.

Navigation tag

The <cms:navigation> tag provides access to the navigation information. The <cms:navigation> tag is described in the /WEB-INF/opencms.tld OpenCms tag library descriptor (TLD).

A Web Container (e.g. Tomcat) uses TLDs to validate tags.

The opencms.tld describes the custom OpenCms tag library.

The navigation tag has six attributes:

var (required)
type(required) can be set to treeForFolder, forFolder, forSite, forResource, breadCrumb
startLevel (optional) that reads the property "NavStartLevel" on resource or folder
endLevel (optional)
resource
param (optional).

Using the navigation tag in a JSP invokes the core method org.opencms.jsp.CmsJspTagNavigation used to access OpenCms VFS navigation information on a JSP with the EL.

Example

 <c:set var="navStartLevel" >
   <cms:property name="NavStartLevel" file="search" default="0" />
 </c:set>
 <cms:navigation type="forFolder" startLevel="${navStartLevel}" var="nav"/>
   <c:forEach items="${nav.items}" var="elem">
     <c:set var="currentLevel" value="${elem.navTreeLevel}" />
     […]
     <a href="<cms:link>${elem.resourceName}</cms:link>">
       ${elem.navText}
     </a>
   </c:forEach>
 </cms:navigation>

Configurable Header and Footer

The OpenCms 8 Template III comes with a configurable header and footer. The default containerpage coming with Template III is placed at /sites/default/.content/.new/default.html

When creating a new or modiying an existing template, header and footer can be added to a page from ADE's "add wizard" by Drag & Drop. The header and footer can be directly edited in ADE. The required HTML of header and footer content are stored at /sites/default/.content/config/c_0001.html as XML content.

The path to the model containerpage can be set and changed in the Sitemap configuration stored at /sites/default/.content/.config.

As a starting point for developing your own Templates there are 3 basic pages (blank.html, twocolumn.html and default.html) which can be used as default when creating a new containerpage (e.g. through the sitemap editor).

A new containerpage is created most easily in the OpenCms 8's new Sitemap Editor. Just click the "Create Page" icon (+) and drag one of the available template pages to the position where you need it in your sitemap.

After creating the new containerpage in the Sitemap Editor, one can easily change the layout by editing the properties.

The Property Configuration in the Sitemap Configuration file at /sites/default/.content/.config defines a 2-or 3-column layout.

Edit properties dialog

Template III example

Clicking through the demo content (Wonderful World of Flowers) - coming with the Template III module - you'll find different examples of 2- or 3-column layout pages.

Example of a 3-column page

Color settings

The different colors for the demo layout are configured in a file of the resource type t3style. This file is placed by default at /sites/default/.content/style

In the demo content this is the following file with the following excerpt:

It is possible to define as many different styles as needed. The Color settings needed for a site or subsite or even a single containerpage get assigned in the "Edit properties" dialog in the Sitemap Editor. Open the OpenCms 8 Sitemap Editor and Click on "Display all resources". Now hidden resources get shown and when editing the properties of a containerpage there are more options available. From the containerpage's context menu select the option "Edit properties". In the opening layover window select "Complete Properties"

In the field "style.layout" one can change the (relative) path to the t3style file defining the color settings.

Quickly changing a style.layout of a containerpage

The "Edit properties" dialog in the Sitemap Editor maps this to the properties assigned to the corresponding resource or folder in the workplace's Explorer view tree structure. Alternatively you can still set the properties directly on the site folder or on a single page:

Example

"style.columns"=3
"style.layout"=/.config/style

The default settings are placed in Template III's main.jsp based at /system/modules/com.alkacon.opencms.v8.template3/templates/main.jsp.

OpenCms 8 List

The Template III List comes as a separate module com.alkacon.opencms.v8.list and adds a new resource type v8list.

The Template III List is a dynamic configurable list and shows resources which are collected with an OpenCms resource collector, for example the collector "allInFolder".

The Template III Listbox allows to configure following attributes:

Tab "General Settings"

Title: The title of the list
Text: The text is displayed above the list entries.
Bottom Text: This text is displayed below the list entries.
Collector: The collector to be used for the resources in the list. The collector can be chosen from a select box.
Parameter: The parameter of the collector to use.
Links: Links to use in the parameters of the collector as macros, e.g. %(link1).
Detail Link Text: (Select Box) The text of the link to the detail view placed after the entry text.
Items per page: The number of displayed items per page. Note: this setting only applies to the center column.
Additional Link:
- Text: The text that is displayed as link.

Tab "Mapping configurations"

Position - Author:: The position of the author relative to the entry. Options: Top, Bottom.
Position - Date:: The position of the date relative to the entry. Options: Top, Bottom.
Position - Image:: The position of the image relative to the entry. Options: Left, Right, Top.
Mapping:
- Field: The field in the list box entry.
- XML Node: The XML path to the element in the XML content.
- Default: The default value if the element in the XML content is empty.
- Max. Length: The maximum length of the text, which will be used.

Example

The screenshot of the Template III demo content shows several examples how to make use of a List in OpenCms 8 Templates.

In the center you can see two Lists formatted for the center column. They both show only 2 resources (can be configured with "Items per page" or "Collector" options).

In the right column a list is configured to fit into a box, with truncated text and resized Image.

Collector

The Collector is an OpenCms widget of the type com.alkacon.opencms.v8.list.CmsCollectorSelectWidget.

It defines the resources to display in the dynamic list.

Choose one of the available collectors:

allInFolderPriorityDateAsc
allInSubTreePriorityDateAsc
allInFolderPriorityDateDesc
allInSubTreePriorityDateDesc
allInFolderPriorityTitleDesc
allInSubTreePriorityTitleDesc
allMappedToUriPriorityDateAsc
allMappedToUriPriorityDateDesc
singleFile
allInFolder
allInFolderDateReleasedDesc
allInFolderNavPos
allInSubTree
allInSubTreeDateReleasedDesc
allInSubTreeNavPos
allInFolderDateDesc
allInFolderDateAsc
allInSubTreeDateDesc
allInSubTreeDateAsc
timeFrameAndCategories
allKeyValuePairFiltered
allVisited
allSubscribed
allSubscribedDeleted
allChangedInFolderDateDesc
allChangedInFolderDateAsc
allChangedInSubTreeDateDesc
allChangedInSubTreeDateAsc

The parameter for the collector has to be set. The parameter should contain the path to the resources to collect, the resource type to collect and the number of resources to collect.

/_contents/events/e_%(number).html|v8event|2 The path to resources to collect |Resource type | Number of resources

The path of resources to collect can be also contain a macro like %(link1), to be defined in the optional "Links" field where you can pick a validated vfslink. If you want to pick only resources of a given name pattern then use a macro expression like e_%(number).html, which limits the selection to file names with the prefix "e_" followed by any number and then the suffix ".html".

As resource type any available resource type known to the OpenCms core can be entered. Do NOT use the Nice name.

The number of resources to collect correlates with the optional "Items per page" that get shown.

Mapping

The tab "Mapping configuration" features several options how the collected resources should be displayed in the list output.

Assuming that most resources will be of the type v8article or its descendants v8news or v8events the fixed attributes Author, Date, Image can be assigned a Position in the displayed list element.

In Addition the every XML node of the chosen resource type could be mapped to a preset of fields.

As list output might need truncation, a maximum length of text output can be preset.

OpenCms 8 Dynamic Function

Since OpenCms 8.0.2 a new resource "Dynamic Function" is introduced. The new resource type makes it possible to drag and drop a dynamic content provided by a JSP directly into a container page of the web site. Typical use case is extending of the web site by a search or login functionality.

The OpenCms 8 Dynamic Function is not part of the Template III but is used by several Template III modules.

The OpenCms 8 Dynamic Function is a new core functionality included in the org.opencms.ade.containerpage module.

The locale is provided by the request parameter specified in the XML content.

The OpenCms 8 Dynamic Function allows to define:

Tab "Main parameters"

Title: The title of the dynamic function
Description: Here you can enter a descriptive text what this dynamic function is used for.
Function provider: Select the path to the JSP that encapsules the functionality as a vfslink.
Parameter:
- Key: Key of the parameter.
- Value: Value of the parameter.
Formatter options:
- Type: Here you can enter a formatter type like center or sidecolumn.
- Minimum: Here you can enter a minimum width for the formatter JSP
- Maximum: Here you can enter a maximum width for the formatter JSP

Tab "Element Settings"

Element Settings:
- Setting name:
- Display name:
- Description:
- Type:
- Widget:
- Default:
- Widget configuration:
- Rule regex:
- Rule type:
- Error:

How to use "Dynamic Function"

Drop a new resource of type "Dynamic Function" into the container page and configure it as XML content from ADE.
Set the title, which is used for this resource in the add wizard.
Define the path to the jsp, which provides the required functionality in the xml field "Funtion provider".
Some optional request parameters can be defined in the XML field "Parameters".
In the XML field "Formatter options" the type of the container as well as its min and max width can be defined to control the container, in which this resource can be dropped.
Additionally define the setting in the second tab directly in the XML content editor. Use the same options as inside of the scheme definition for the resource type.

Important note: The html output provided by the used jsp should be surrounded by a <div> tag, similar to the formatter JSP.

OpenCms 8 Login Form

The Template III Login Form comes as a separate module com.alkacon.opencms.v8.login.

The Template III Login Form is implemented as a "Dynamic Function" since OpenCms 8.0.2 and is of resource type function.

The Template III Login Form can be used to provide Log in functionality for a protected area on the website.

OpenCms 8 Search Form

The Template III Search Form comes as a separate module com.alkacon.opencms.v8.search.

The Template III Search Form is implemented as a "Dynamic Function" since OpenCms 8.0.2 and is of resource type function.

The Template III Search Form offers full text search on the website.

Search configuration (as parameters for "Dynamic Function")

Search Index: VFS search index for Search Management in OpenCms Administration.
Search source: Defines the path to be searched (e.g. root "/").
Matches pro page: Here you can enter maximum number of displayed search results per page. With pagination more results will be displayed on next pages.

How to use the search form

Drop a search box from ADE's Add wizard "Dynamic Function" list to the left or right column.
The parameter 'searchformlink' needs to be set and point to the search result page (e.g. /flower-en/flower-search/)
Add a new search form detailpage from ADE's Add wizard "Dynamic Function" list to the designated search result page (e.g. /flower-en/flower-search/)
To use the SearchResult.JSP as function provider the following parameters may be set:
- 'searchIndex' to set the index searched, default: 'Online project EN (VFS)'
- 'searchRoot' to set the folder to be searched, default: '/'
- 'searchMatchesPerPage' to set the number of results displayed per page, default: '5'

Now the search results are displayed on the detail page (e.g. /flower-en/flower-search/)

OpenCms 8 Twitter Feed

The Template III Twitter Feed comes as a separate module com.alkacon.opencms.v8.twitter.

The Template III Twitter Feed adds an official Twitter widget and provides functionality to define a Twitter Feed with:

Title: The title of the twitter feed
User: The twitter user. Tweets of this twitter user will get displayed (e.g. AlkaconOpenCms)
Backgroundcolor:Please select the color of the twitter feed.
Links Color: Please select the color for the links.

In ADE one can directly edit the twitter feed's "Element Settings". Options are:

Twitter box height: The height of the twitter box

Dev Demo Template

The OpenCms 8 Developer Demo provides a collection of technology examples and common use cases. It consists of several small examples, so that each example is easy to understand.

All demo examples have a similar structure:

Each demo example has its own sub-sitemap.
The path to the sub sitemap of a demo example is:

/sites/default/dev-demo/{example-name}/

The path to the sub-sitemap configuration of a demo example is:

/sites/default/dev-demo/{example-name}/.content/.config

The path to the content of a demo example is:

/sites/default/dev-demo/{example-name}/.content/

The Dev Demo contains the following examples

Formatter demo

Image scale demo

This example demonstrates how to scale the size of an image dynamically. The scaling depends on the width of the container, in which this article is dropped. The image size is set dynamically inside of the formatter using container width. You have to define the container width as an attribute of the <cms:container> tag inside of the template. Then you can access the container width inside of the formatter.

Settings demo

For this example several settings were defined in the xml schema definition of the article. The values of the settings are accessed inside of the formatter and used for example to control the layout options of this article on this containerpage.

Dynamic function demo

Demo of the dynamic function

Since OpenCms 8.0.2 a new resource "Dynamic Functionality" is introduced. The new resource type make it possible to drag and drop a dynamic content provided by a jsp directly into a container page of the web site. Typical use case is extending of the web site by a search or login functionality.

In this demo example a simple date display is added in a box, which can be dropped in one of the side containers. The settings are used to set the format and the style of the date. The locale is provided by the request paremeter specified in the xmlcontent.

How to use "Dynamic Functionality":

Drop a new resource of type "Dynamic Funcionality" into the container page and configure it as xmlcontent from ADE.
Set the title, which is used for this resource in the add wizard.
Define the path to the jsp, which provides the required functionality in the xml field "Funtion provider".
Some optional request parameters can be deifined in the xml field "Parameters".
In the xml field "Formatter options" the type of the container as well as its min and max width can be defined to control the container, in which this resource can be dropped.
Additionally define the setting in the second tab directly in the xmlContent editor. Use the same options as inside of the scheme definition for the resource type.

Container variables demo

Access of the container variables

Specific information about differnet containers on a container page as well as adjusted information of a container element is provided by org.opencms.jsp.util.CmsJspStandardContextBean. This bean is available from a jsp like formatter, as soon as the container page is rendered. The values of the bean are adjusted depending on the element it is called from. In order to access the CmsJspStandardContextBean from a jsp use a predefined EL variable ${cms}.

In this demo different variables available inside of the current element are displayed. These variables describe the current state of the container page and of the current container.

Headinclude tag demo

In OpenCms 8 it is possibe to use additional javascript or css files to display a specific resource type. The paths to the additional files can be set inside of the resource type scheme. The referenced files are loaded dynamically, if the reource type is used on a container page.

To include the javascript or css files follow the inscructions:

Reference the javascript or css files inside of the resource type scheme using <headinclude> node.

Please compare:

/system/modules/org.opencms.dev.demo/schemas/article_with_headincludes.xsd

Use the javascript or css information inside of the formatter of the resource type.
Add following lines to the html <head> area of the template:

<cms:headincludes type="javascript" />
<cms:headincludes type="css" />

Paste script Demo

With OpenCms 8 you can paste scripts like Facebook Like Button directly inside of your content, by defining a special area inside of the formatter.

Define two different contents areas inside of the element formatter using ${cms.edited} varible. If the page have been reloaded the part of the html code containing the pasted scripts is displayed.

A model is a default copy model for the containerpages, where common content which should appear on all new containerpages is defined. Usually the containerpage model is in folder of the sub sitemap:

/{sitefolder}/{sub sitemap path}/.content/.new/

In order to use the model, its path has to be set in the sitemap configuration inside of the tab "Page Models".

The defined page model will then appear as first in the list of containerpages in the "Create Page" dialog of the sitemap editor. In order to have a nice name for the new page model, please edit additionally its title property. If set as default this model is also used to create the new page, when it is added over the context menu in the sitemap editor. Futher use the disabled checkbox of the page model configuration to control the visibility of the inherited page models from the upper sitemaps.
