How to Access[edit]

Select Extensions -> Install/Uninstall from the drop-down menu in the Back-end of your Joomla! installation.

Description[edit]

Extensions are add-ons to Joomla! that build on and expand the functionality of Joomla!. Extensions are used to add capabilities to Joomla! that do not exist in the base core code. Hundreds of Extensions are available for Joomla!, with more being developed all of the time.

Extensions are categorized into five types, as follows:

  • A Component is a mini-application that renders the main body of the page. Examples of components are Contacts, the Front Page, and News Feeds.
  • A Module is a smaller Extension typically used for rendering a small element that displays across multiple pages. Examples of Modules include Menus and Related Items.
  • A Plugin is a section of code that runs when a pre-defined event happens within Joomla!. For example, editors are plug-ins that run when an edit session is opened.
  • The Language Extension allows for the Front-end and Back-end of Joomla! to be presented in any language for which a language Extension exists. This way, Joomla! can be released in a new language with no changes to the core program.
  • A Template controls the way the content of a web site is displayed, including the location and layout of elements, colors, fonts, and so on. Templates allow the appearance of the web site to be separated from it's content.

This screen is organized into six sections as follows:

  • Install: Allows you to install all types of Extensions.
  • Components, Modules, Plugins, Languages, Templates: Allows you to enable, disable, and uninstall Extensions of each type.

Install Screen[edit]

Details[edit]

The normal procedure for installing a Joomla! Extension is as follows:

  1. Download one or more archive files (normally ".zip" or "tar.gz" format) from the Extension provider's web site to a local directory on your computer. Note that some Extensions are installed as one file (for example, one Component or Module) while other Extensions might have two or more files (for example, a Component and a Module). If there are two or more parts, each one will have its own archive file.
  2. Use the "Browse" button in the "Upload Package File" to browse to each archive file.
  3. Use the "Upload Package File" button to install the Extension. Joomla! then unpacks the archive file and installs the Extension.
  4. Depending on the Extension, it may be necessary to enable the Extension (for example, in the Module Manager or Plugin Manager).
  • Upload Package File. Browse to the location where you downloaded the Extension's archive file. Then press "Upload File & Install". Joomla! will read the contents of the archive file and install the Extension. When it is finished, the screen will display the message "Install Component Success". If the installation is not successful, an error message will display.
  • Install from Directory. As an alternative to installing from an archive file, you can follow the steps below:
    1. Create a temporary directory on your local hard drive and unpack the Extension's archive file in this temporary directory.
    2. Using FTP, upload the contents of this directory (including files and subdirectories) to a directory on your server.
    3. In the Install Directory field specify the directory where you have uploaded the files and subdirectories of the package.
    4. Click on the Install button and Joomla! will install the contents of the given directory.

When it is finished, the screen will display the message "Install Component Success". If the installation is not successful, an error message will display.

  • Install from URL. A third alternative for installing an Extension is as follows. Instead of downloading the archive file to your local computer, just specify the URL of the target archive file. Then click the "Install" button and Joomla! automatically installs it directly from this URL. Again, the screen will display the message "Install Component Success". If the installation is not successful, an error message will display. Note that, with this method, you will not have a copy of the archive file on your local computer.

Quick Tips[edit]

Think twice if you want to uninstall a Joomla addon. For example sometimes it is a good idea to unpublish the modules you don't want to show on frontend. Generally the bundled Joomla modules cannot be reinstalled without a hitch.

Disable a component

If you do not want to use a component, then switch to the Components tab and click the green tick in the Enabled column. The green tick will be replaced with a red X. The disabled component will disappear in the Components menu.

Support old Extensions in Legacy Mode

Some old 1.0.x Extensions support Joomla! 1.5 in Legacy Mode. To be able to install such Extensions please open the Plugin Manager screen from the Extensions menu and enable plugin System - Legacy as it is disabled by the default.

You can choose the mode of the installation. The mode used most frequently is the Upload Package File.

Some Core or System addons (Component, Module, Plugin) cannot be uninstalled so cannot be selected for uninstallation. Also the Default Template and Language are disabled for selection.

Important: Do not delete the Default Template and Languege files using FTP because it generates errors in error both front-end and back-end.

When you want to install a 3rd party developed module or plugin which belongs to a component, please keep in mind that you cannot use it unless you first install the related component.

When you uninstall a 3rd party developed component having its own module(s) or plugin(s), these modules cannot be used any more, so please uninstall them as well.

Some components coded by 3rd party developers may have their own modules and/or plugins included in the installer, so make sure the module/plugin directories are writable otherwise the Extension will not work properly.

SECURITY WARNING: Please use only those 3rd party Extensions on your site which you really need. Do not use your live site for testing purposes because it may compromise your site and server.

Please do not install Joomla! Extensions downloaded from warez sites because they may be infected by a virus or malware that cause damage on the server and can contaminate the computer of your visitors! Installing from remote URL can be dangerous as well.
