Joomla Components is usually self-explanatory, but that does not mean they are easy to understand. It is easier to understand what those components do, but they have to be put together with the other Joomla files. How do you do that? It is an easy thing to do, but you have to know what you are doing.
The basic parts of a web page are HTML and text. HTML is short for Hypertext Markup Language, and text is words and HTML. These elements may be coded in different ways, depending on the sort of web site and the organization of those sites.
In order to get the page to display properly, you must have Joomla Files that includes the Java programming language. There are two kinds of such files, and the most basic Joomla components are either add-ons, which are just scripts in HTML format, or libraries, which are created with a mix of scripting languages like PHP and Java. There are also frameworks for many systems, in order to create applications with the Java scripting language.
For instance, suppose you have a website where there are more than classic text files and icons and pictures, like you see on some news sites or in Google’s applications. You also have some other graphics to accompany your text, for example, you may have an image for each paragraph.
To install the add-on into your website, you have to add it to the root of your website. Thereis a Scripts Manager in the Joomla Package Manager to give you a list of all the add-ons in your website. The one you choose is called MyAddons. You can install as many add-ons as you like, but you cannot delete any of them.
Every time you make changes to your website, you have to update the Add-on in Joomla. It does not have to be the whole thing, just the script you want to include in your website. You can change the Content to put in the script, for example, or the appearance of the page. There is a slider, that lets you change the appearance and behavior of the website.
Now, whenever you make a change to your website, the website has to be updated with the correct add-on in Joomla. The script has to work. If there is an error, the whole thing will be very difficult to use. That is why you have to test, in the usual way.
It does not work if the add-on cannot find the Script to run. It does not work if it cannot find the Add-on. If that happens, you have to get in touch with the creator of the add-on and find out where it could have gone wrong.
So if you have trouble with this, you may try using a script that allows you to create new pages in the Joomla file system. This is called a module. This is similar to a regular PHP script, but it does not change any of the HTML.
You have to create a module, add it to the bottom of the existing pages, and have a checkbox checked in the Preferences Panel. It will tell you that this is the place where you will put the modules for the website.
