Cannot find the component/module that completely meets your requirements within the standard Joomla extensions? Then create it by yourself! In this article I will tell you a simple way to create a unique Joomla extension.

Create a component

Of course, you should have some programming skills to create a difficult component. But writing of php code is not the point of this article. I would like to focus on how it works in Joomla here.

So, in the root folder of your site, navigate to the components folder and create there a folder named as com_myscript (com_ is compulsory prefix and myscript – name of your component). Then create myscript.php file and put it into that folder. When done, you’ll have the .php file with the following path:

../components/com_myscript/myscript.php

Open the file and insert a simple php code there. For example,

<?php
# my script
echo "Hello World!";
?>

Save myscript.php. Your component is ready!

Create a module

Process of creating a new module is similar to creating of the component.

Create mod_ myscript folder within the ../modules/ in the root of your site and put mod_myscript.php file there. As usual, mod_ is compulsory prefix, and myscript is a name of new module. The path to your script should look like:

../modules/mod_myscript/mod_myscript.php

Insert php code into the file and save it.

Then create mod_myscript.xml file and place it at the same folder:

../modules/mod_myscript/mod_myscript.xml

You can use .xml file for some other module as an example. The necessary content of this file would be like the following:

<?xml version="1.0" encoding="utf-8" ?>

- <install type="module" version="1.5.0">

<name>Login</name>

<filename module="mod_myscript">mod_myscript.php</filename>

</files>

</install>

Save the file and enjoy! Your module is ready.

Run the script

So, you have the required component/module. How you can run the script? Very simple – in the address bar of your browser, add /index.php?option=myscript to the URL of your site. Now the URL looks like:

http://mysiteaddress//index.php?option=myscript

You can run any script from your site in such way.
