Everybody knows that Joomla is an excellent CMS to get building professional internet sites. The JED (Joomla Extension Directory) abounds with elements, modules and plugins that can add nearly every type of functionality to the Joomla web site. That's great and all but you may be wondering what if you find a component or module that gives features needed but the output and layout is not exactly what you need? A huge mistake that some developers and webmasters make is certainly going in and editing the core code of the extension. Joomla makes it easy simply by allowing overrides.
What is a good Override?
An override is really a copy of the plug-ins layout/template file that is put into your own Joomla template index. You can then customize it want. The difference with carrying this out as are at odds of to just modifying the file in the extension directory site is that when you upgrade Joomla or maybe the extension, your changes will never be replace by the brand new versions. Joomla understands to look within the overridden file first, then your actual extensions file.
How do I Create an Override?
Producing an override is simple. For the sake of this tutorial, let's say that individuals wish to edit the output from the login web page. By default, the login page offers 3 links in an unordered list (forgot password, forgot user name and don't have an account).

For the sake of this tutorial, let's say that people never want the last "Don't have an account" link and we furthermore do not want these questions checklist, we simply want the two other links side by side. The changes we make do not really matter at this time. It is just to exhibit you how an override functions. Automatically, Joomla uses the com_users aspect of handle sign in and enrollment. The particular com_users component provides multiple views/layouts. We can see all of them by going tojoomlasite/components/com_users/views

You can see you will find 5 various views. We would like to modify the login web page so we would like the sign in folder/view. In case you click that, you will then get a tmpl folder. This is the template for this specific view. Within the tmpl file is where design files are located. Practically all element and module tmpl folders have a arrears. php document. Some components such as this have additional template documents. You component login view has default. php, default_login. php anddefault_logout. php.

The default_login. php file is the one we have to edit the login type page. And we need to take that file make it to the Joomla design template folder framework. Visit your main Joomla design template folder. This would be injoomlasite/templates/yourtemplatname. You need to make a new file called code. In this html file, create one more called com_users and after that for the reason that, another folder known as login. This is when you wish to place the default_login. php document that you copied. So the full path would certainly bejoomlasite/templates/yourtemplatename/html/com_users/login/default_login. php
Modifying the particular default_login. php Document Right now whenever we do something about it and save the particular default_login. php override document, Joomla will appear for this file 1st. Let's make the small alter of removing the list as well as the last hyperlink In the brand new default_login. php file, you will see the next program code
It is the unordered listing with the three or more links. Let's edit this simply by removing the list tags and achieving rid of the next link together with the in case statement. So it may be like this particular
Right now save the file and go back to your frontend login web page.

You can now note that record formatting and the 3rd hyperlink are both long gone. So now in case you revise Joomla core documents or update the com_users component, this alter would stay with the site as oppose to just getting written more than. This is extremely within Joomla webdevelopment. You can accomplish this with any component or module under the typical Joomla construction.
