connect with external database in joomla


Joomla! Is an open source website development and content management system (CMS) platform that is free to use. Joomla! Like other content management systems, it automates much of the technical aspects of creating and maintaining a website.

Some noteworthy aspects include:

  • Offers plug-ins and site modules to improve webpages and content; over 6000 extensions are accessible.
  • Responsive templates optimize webpages for many platforms, including mobile devices.         
  • Permission levels limit site user file access while granting site workers access to the files they require to complete their tasks.
  • Support for many languages for various sites or sections of a site. 
  • Polls, search, and web link management and analysis are all supported.

Joomla! is based on Mambo, an older CMS developed by the same software’s development team. Joomla! Was founded by the development team to enhance and safeguard open source principles that they felt were being exposed.

Over the last decade, Joomla has grown to become one of the most extensively used content management systems on a global scale. It has effectively captured a vast audience since its introduction in 2005, with over 99 + million downloads to date.

Joomla is created in PHP and stores data in a MySQL database using object-oriented programming techniques. It may be installed with a single click from the web hosting management panel. There are hundreds of articles on the web that will show you how to install Joomla. There are several Jooomla hosting options available.

The Model-View-Controller (MVC) design architecture is used by Joomla. When Joomla processes a request, it first analyses the URL to determine which component will handle the request, according to the MVC pattern. The model holds the data that the component uses. It is also the Model’s responsibility to update the database as needed. The view is responsible for the output. It can make contact with the model to obtain the necessary information.  After the output of the view has been produced, the component returns control to the Joomla framework, which then executes the template.

So, while learning What is Joomla, you also become acquainted with how Joomla’s internal mechanism functions. Let’s get back to the matter. Joomla is a well-known open source CMS, but do you understand what a CMS is? If so, excellent; if not, see the explanation below.

Advantages of Joomla

Joomla is a powerful choice for building a website of any size. Some of its key characteristics are listed below.

Simple to Use

Joomla is an open source project that is completely free to use. But just because it’s free doesn’t mean it’s lacking in functionality. In fact, the entirely user-friendly interface will astound you with its WYSIWYG function, which produces identical results every time. Another thing to be happy with is the frequent updates. Joomla is constantly being updated with new features and functionality. It becomes easier to work with each new update.

Responsive in Nature

Nowadays, having a responsive website is expected. Because every second person is using a smartphone to access the internet. As a result, it is essential to create a website that functions flawlessly on any device of any size. And Joomla provides you with a fully responsive website. As a result, you will never lose a potential website visitor.

Exceptional Security

Security is an important consideration while developing a website. To reduce the possibility of hacking, Joomla offers two-factor authentication. So your site will not be hacked, but if you choose a very popular login and password and someone gains access, you can quickly recover the compromised Joomla site.


Being multilingual benefits everyone. Obviously, it is a feature to be glad about for individuals who do not understand English. Yes! Joomla supports multiple languages. It supports 75 different languages. I must admit, this is a lengthy list.

Joomla is easy to use. There are also a number of other factors that make it simple to work with. And it is distinguished by these characteristics.

What makes Joomla the best choice?

Apart from the advantages mentioned above, there are countless other reasons to use Joomla. Let’s dive into the vast ocean of Joomla features.

  • Joomla will provide you with a fully SEO optimised website. There are several Joomla SEO techniques that might help you build a great website.
  • Over 8,000 extensions are available to dazzle you with their features.
  • User Management (ACL), where ACL stands for Access Control List, which is useful for controlling your site’s users.
  • Create as many menus as you wish.
  • Images are simple to manage.
  • URL redirection is a straightforward process.
  • Adding a contact form is simple.
  • Get updates with a single click.

But sometimes we may need to use any external database within our existing Joomla setup. Of course we can do it by using core PHP code. But this is not a good way to follow. So we can connect with the external database using below code.

$options = array();
$options['driver'] = 'mysql';
$options['host'] = 'localhost';
$options['user'] = 'dbuser';
$options['password'] = 'dbpassword';
$options['database'] = 'databasename';
$options['prefix'] = 'tblprefix_';
$db = & JDatabase::getInstance($options);
$query = "SELECT * FROM #__example_table";
return $db->loadAssocList();

We should put all database connection related information in array variable $options. Then use the getInstance() function from Database. Now you can use Joomla’s default database operation.

So, these are some of the most notable things that Joomla has to offer. It does, however, this article will allow you to employ a variety of third-party extensions and plugins. The Joomla Extensions Directory has thousands of vetted third-party extensions to improve your site experience.
