In my Joomla application, I have functionality where I use server variables, like request_uri and query parameters for parsing url string.

This function is used in many modules. So, I wanted to implement the same functionality by using a custom plugin, following Joomla tutorial.

My question is whether using a plugin in this case is appropriate.
And can we use server objects in a plugin class?

If yes, how to use this plugin in my other modules and components.

Any detailed answers are appreciated.

  • Can you provide a bit more detail regarding how your modules will use the gathered information? Also, if you're simply grabbing URL query parameters there's a much, much, much simpler way using Joomla core. Commented May 17, 2016 at 15:28

You could create your own library with the functionality you want to re-use in all your extensions and load it each time with JLoader.

The $_SERVER is a SUPERGLOBAL variable and can be accessed anytime from everywhere.

Since you are working with Joomla, you may want to use what Joomla has to offer, so have a look at JURI

Job could be done with a plugin as well. For example you could create a system plugin and in your plugin's classes create public methods.

Accessing your plugin from your modules:

$myPluginFramework = new MyPluginFramework();


Note that the plugin must be enabled in order to be able to create a new object of your plugin class. You probably have to consider any checks for if the class exists

if (class_exists('MyPluginFramework')) {
    $myPluginFramework = new MyPluginFramework();
  • Is it necessarily be a system plugin? Or can i use a content plugin with an event like on content prepare

  • @user168983: I don't see how the onContentPrepare would be useful in your case, and generally a system plugin sounds a better fit in the context of your needs. Again, I think it could be better if you simply create your own lib (framework) and use it in your extensions as and when needed.
