Joomla! Plugins

Simon Grange.

 

Joomla! has 50 native plugins. There are 11 types of plugins: Authentication, Captcha, Content, Editors, Editors-XTD, Extension, Finder, Quickicon, Search, System, User. Most plugins are enabled by default, the others are disabled.

You must be extra careful when manipulating plugins.

For example, deactivating some plugins can lead to the inability to access your site.

On the other hand, if you want to access some of your site's features (such as the multilingual system or the smart search for example), just enabling the corresponding plugins won't be enough, you will also need to configure other parameters.

In any case, it's recommended that you back up your site before manipulating plugins.

To access your plugins, select ExtensionsPlugin Manager. Thanks to the filter “by type”, you can display the list of plugins by type.

 

Authentication

The 3 Authentication plugins allow you (and other users) to connect to the website, to the Backend and to the Frontend.

Caution: At least one of the three authentication plugins must be enabled, otherwise you won't be able to access your site.

Authentication - Joomla

The Authentication - Joomla plugin is the default authentication system of Joomla!. It checks the filled-in information in the authentication module.

Enabled by default.

 

Authentication - Gmail

The Authentication - Gmail plugin allows users to login to the site using their gmail account (email address and password). This plugin requires cURL.

Disabled by default.

 

Authentication - LDAP

The Authentication - LDAP plugin enables users' authentication from a LDAP server.

Disabled by default.

 

Authentication - Cookie

The Authentication - Cookie plugin stores users' authentication cookies.

Enabled by default.

 

Captcha

A Captcha is a feature determining whether the user who fills in a form is a human or not. You've probably already seen Captchas, these tests can be text-based (words are distorted and therefore usually difficult to read), they can be made of simple math problems or of images to select from a list.

Captcha - ReCaptcha

The Captcha - ReCaptcha plugin allows you to add a Google Captcha to your forms (your contact or registration forms for example) to protect against spammers. To make this plugin work, you need a public and a private key (to be entered in the plugin's basic settings). You can easily get the keys from this site: http://www.google.com/recaptcha.

Enabled by default.

 

Content

Content - Smart Search

The Content - Smart Search plugin allows indexing your site content, which is required to use the Smart Search feature.

Disabled by default.

 

Content - Joomla!

The Content - Joomla plugin undertakes two different tasks:

  • Check category deletion - When deleting a category (e.g. an article, a contact...), it checks that the category is fully empty (that it doesn't have items or sub-categories). If you try to delete a category that isn't fully empty, you will get a message telling you that this category has items.
  • Email on new site article - When submitting a new article via the Frontend, an email will be sent to users whose "Send email" system notification parameter is enabled. This parameter can be configured in each user's profile.

These two functionalities can be easily disabled in the plugin's basic settings.

Enabled by default.

With this plugin, you can also create a Table of Contents.

Enabled by default.

 

Content - Page Navigation

The Content - Page Navigation plugin enables the Next & Previous links at the bottom of your article pages. These links allow users to navigate your other articles. This setting can also be configured in the article itself, in the main settings and in the menu item options if the article is displayed via a menu item.

Enabled by default.

 

Content - Vote

The Content - Vote enables a voting system so users can rate the site's articles.

Enabled by default.

You can choose which editor you want to use:

WYSIWYG stands for: "What you see is what you get".
