There are different ways to link articles, or pages, together using Joomla! 3.0. There is a core Joomla! functionality approach, and a way to link using the JCE editor (which is a third party extension). This article contains step-by-step instructions for linking two articles together using core Joomla! functionality and a function found in the JCE Editor.
Linking Articles together using core Joomla! functions
Log in to the Administration area (the back end) of your site, go to your Article Manager, and open the Article where you'd like to create the link. Once the article is open, you'll notice four settings that you can control at the bottom of the area where you insert text.
Once the article is open, highlight the text that you would like to link to another article, and select the "Article" link that is below the Article Text area.
In the window that opens, select the article where the link will be directed.
Once you select the article, you will be returned to the Article Manager. Notice how the text you highlighted has changed to match the title of the Article that you linked. Unfortunately, there is no way to change this feature. If this doesn't work for you, can download and install the JCE Editor for your site and follow the directions below.
Be sure to save your work. Return to the front end of your site, and open the Article where you created the link. Test it; it should be active.
Linking Article together using the JCE Editor
You're other options to link articles together is using the JCE Editor. Log in to the Administration area (the back end) of your site, go to your Article Manager, and open the Article where you d like to create the link. Once the article is open, highlight the text that you would like to link to another article, and look for the chain link icon inside of the editor.
In the window that opens, you can add an external URL to direct the link outside of your site, or you can open the Content area to create the link internally. You can also specify if you'd like the link to open up in a new window, in the current window, etc. This is the "Target" field.
Once you make your selections, you'll see that the link is active, but, unlike the link that was created with the core Joomla! functions, the text didn't automatically change.
Save your work. Return to the front end, hit refresh, and you can test the link to see if it works.
