Conceptos en Joomla

Plugins are small task oriented extensions that enhance the Joomla! framework. Some are associated with particular extensions and others, such as editors, are used across all of Joomla!. Most beginning users do not need to change any of the plugins that install with Joomla!. Help

 Templates give your site its look and feel. They determine layout, colors, type faces, graphics and other aspects of design that make your site unique. Your installation of Joomla comes prepackaged with four templates.

Modules are small blocks of content that can be displayed in positions on a web page. The menus on this site are displayed in modules. The core of Joomla! includes 17 separate modules ranging from login to search to random images. Each module has a name that starts mod_ but when it displays it has a title. In the descriptions in this section, the titles are the same as the names.
  • Content Modules
    Content modules display article and other information from the content component.
  • User Modules
    User modules interact with the user system, allowing users to login, showing who is logged in, and showing the most recently registered users.
  • Display Modules
    These modules display information from components other than content and user. These include weblinks, news feeds and the media manager.
  • Utility Modules
    Utility modules provide useful functionality such as search, syndication, and statistics.
  • Navigation Modules
    Navigation modules help your visitors move through your site and find what they need.
    Menus provide your site with structure and help your visitors navigate your site.  Although they are all based on the same menu module, the variety of ways menus are used in the sample data show how flexible this module is.
    A menu can range from extremely simple (for example the top menu or the menu for the Australian Parks sample site) to extremely complex (for example the About Joomla! menu with its many levels). They can also be used for other types of presentation such as the site map linked from the "This Site" menu.
    Breadcrumbs provide users with information about where they are in a site.

    Newsflash Example

    Newsflash is a Module which will display Articles from your site in an assignable Module position. It can be used and configured to display one Category, all Categories, or to randomly choose Articles to highlight to Users. It will display as much of an Article as you set, and will show a Read more... link to take the User to the full Article.
    The Newsflash Component is particularly useful for things like Site News or to show the latest Article added to your Web site.
Components are larger extensions that produce the major content for your site. Each component has one or more "views" that control how content is displayed.In the Joomla! administrator there are additional extensions suce as Menus, Redirection, and the extension managers.

Many of Joomla!'s core features are provided by the use of default Components such as:
  • Contacts
  • Front Page
  • News Feeds
  • Banners
  • Mass Mail
  • Polls
A Component will manage data, set displays, provide functions, and in general can perform any operation that does not fall under the general functions of the core code.
Components work hand in hand with Modules and Plugins to provide a rich variety of content display and functionality aside from the standard Article and content display. They make it possible to completely transform Joomla! and greatly expand its capabilities.

Extensions:The Joomla! content management system lets you create webpages of various types using extensions.
There are 5 basic types of extensions:
components
modules
templates
languages
plugins.
Your website includes the extensions you need to create a basic website in English, but thousands of additional extensions of all types are available.
The Joomla! Extensions Directory is the largest directory of Joomla! extensions.

 Language. Joomla! is released with multiple Installation Languages but the base Site and Administrator are packaged in just the one Language en-GB - being English with GB spelling for example. To include all the translations currently available would bloat the core package and make it unmanageable for uploading purposes. The Language files enable all the User interfaces both Front-end and Back-end to be presented in the local preferred language. Note these packs do not have any impact on the actual content such as Articles.
More information on languages is available from the
http://community.joomla.org/translations.html

Content

Joomla! makes it extremely easy to add and display content. All content is placed where your mainbody tag in your template is located. There are three main types of layouts available in Joomla! and all of them can be customised via parameters. The display and parameters are set in the Menu Item used to display the content your working on. You create these layouts by creating a Menu Item and choosing how you want the content to display.

Blog Layout

Blog layout will show a listing of all Articles of the selected blog type (Section or Category) in the mainbody position of your template. It will give you the standard title, and Intro of each Article in that particular Category and/or Section. You can customise this layout via the use of the Preferences and Parameters, (See Article Parameters) this is done from the Menu not the Section Manager!

Blog Archive Layout

A Blog Archive layout will give you a similar output of Articles as the normal Blog Display but will add, at the top, two drop down lists for month and year plus a search button to allow Users to search for all Archived Articles from a specific month and year.

List Layout

Table layout will simply give you a tabular list of all the titles in that particular Section or Category. No Intro text will be displayed just the titles. You can set how many titles will be displayed in this table by Parameters. The table layout will also provide a filter Section so that Users can reorder, filter, and set how many titles are listed on a single page (up to 50)

Wrapper

Wrappers allow you to place stand alone applications and Third Party Web sites inside your Joomla! site. The content within a Wrapper appears within the primary content area defined by the "mainbody" tag and allows you to display their content as a part of your own site. A Wrapper will place an IFRAME into the content Section of your Web site and wrap your standard template navigation around it so it appears in the same way an Article would.

Content Parameters

The parameters for each layout type can be found on the right hand side of the editor boxes in the Menu Item configuration screen. The parameters available depend largely on what kind of layout you are configuring.
