Joomla Google Map Plugin

[Reggie Lamborn]

Aplugin is a kind of Joomla! extension. Plugins provide functions which are associated with trigger events. Joomla provides a set of core plugin events, but any extension can fire (custom) events. When a particular event occurs, all plugin functions of the type associated with the event are executed in sequence. This is a powerful way of extending the functionality of Joomla. It also offers extension developers a way to allow other extensions to respond to their actions, making extensions extensible.

The Joomla! plugin architecture follows the Observer design pattern. The JPlugin class provides the means to register custom plugin code with core or custom events. The JEventDispatcher class is an event handler which calls all plugins registered for a particular event, when that event is triggered. In Joomla 4.x this has been moved to the \Joomla\Event\Dispatcher class in Joomla, and additionally follows the Mediator design pattern

To understand the principles on which the Plugin system works Plugin Developer Overview. To then implement this in a component you have designed it is recommended to read Supporting plugins in your component.

Plugins are grouped together depending on which event they run on. For developer reference there is a full list of plugins grouped by their event type. Please note, the names of a lot of events changed between the Joomla 1.5 and Joomla 2.5 versions. Here is a full list of the 1.5 to 2.5 plugin event name changes. There are also several simple tutorials on making some sample plugins running on some of these events to help running searches on extensions using both the search and smart search components:

I figured that but since the developer has no way to contact them I thought maybe you should know so you could remove it from your plugins since clearly it does not do what it advertises since it wont even install.

@DaveOzric care to share what you did?

I have a number of sites on shared space and having issues with browser blocking because the tracking link is to another domain.

Looking to sort out where to best place this.

Thanks

As part of Joomla! 5.0 a plugin was introduced which enhance backward compatibility between Joomla 5 and 4.The plugin is implemented as "Behaviour" plugin type to guarantee that is loaded before any other plugin is loaded.(Just a heads-up, don't create a plugin as behaviour plugin because it's possible that this group get removed at some point)

Having the plugin active should allow a seamless update from Joomla 4 and allow to install not update Joomla extensionsto be installed in Joomla 5. This gives extension developers or own developments additional 2 years time to update oldcode to the current standard.

For the first option it's more tricky because the class aliases which are provided here did exist since Joomla 1.0 butget deprecated and replaced starting with Joomla 3.3 around 2014 and continued to be filled till 3.10. The reason forthe renaming of the classes was part of the move of Joomla to namespaces.

If you disabled the plugin by accident or by try and get a php error you have to re-enable the plugin in the databaseagain. This can be achieved by editing the enabled column in the #__extensions table for the row with the nameplg_behaviour_compat and set it to 1.

Please do not disable this plugin on your production page, please try to disable the plugin on a test copy first.Make sure you have access to the db. That way, you can enable the plugin again quickly if needed.

The es5 entries has been removed in 5.0 since no browser which doesn't support es6+ is maintained any more.The way our Webassetmanager works doesn't allow us to simply remove assets. For this reason we have alles5 entries moved to the b/c plugin and provide an empty dummy entry.

This system security plugin helps site owners easily configure the HTTP Security Headers from Joomla's familiar backend, rather than having to rummage around in the htaccess file or other configuration files. Or, even worse, your web hosting Cpanel.

Look at how complicated this is to set up in Cpanel and tell me you won't make a mistake! And, that's all assuming that once the framework's installed in Apache and directories made, you know the correct format to add the HTTP headers you want to integrate.

HTTP headers are not to be confused with the section of your HTML document. They are completely different. HTTP headers are the preamble between your web server and the browser. A set of instructions that tell the browser what, or more importantly, what not to display to the visitor.

You can see The HTTP Headers and how they pertain to individual HTML objects in your browsers DEV Tools. In Google Chrome, open the DEV Tools, then the Network tab. Now refresh the webpage and click on an HTML item in the left pane. It will display the HTTP Header for that item in the right pane.

You can see in the image below that the highlighted image is returning an HTTP status of 200, so the browser found it. There's also a range of other information linked to that item, such as file size and edit dates.

If one of your HTML items has failed to display, you may also get a clue about the reason in the HTTP headers. In this example, the second picture has failed to display and you can see from the information displayed in the right-hand pane there is no HTTP Header information.

'Strict-origin-when-cross-origin' simply means that when an HTML item (an image in this case) is served from a different source (not your server), then the HTTP header policy set at that time must be followed. In this example the HTTP Headers, as set in the Joomla plugin, will reject all images that do not originate from either this website, or a different website that's specifically 'included' in the HTTP Header parameters set in the Joomla HTTP header plugin.

Which differs from not being found and returning a 404 not found HTTP error message. In this situation, the image is still being looked for on the server that hosts it, but the browser has not found it.

Apart from telling the browser what to display and returning general information about the HTML document, HTTP Headers help to mitigate attacks and security vulnerabilities you may have on your Joomla website. That's where the Joomla HTTP Headers plugin comes into its element. It achieves this by explicitly displaying HTML content based on your settings in the Joomla HTTP Headers plugin itself.

This is important, because by default an HTML webpage will display all of its content to your visitor, good or bad. That's unless it's explicitly told not to in the web page's HTTP headers. The plugin does this by allowing you to configure the advanced security options available to you in the Content-Security-Policy for your website. the plugin can be configured differently for each website depending on your requirements, so it's a truly flexible weapon in your armoury against hackers.

In an ideal world, you wouldn't. However, in the world we live in, there are far too many unscrupulous people trying to find ways to make money from the innocent and unwary. In our world, we refer to these people as hackers. Hackers go out of their way to exploit vulnerabilities in software for monetary gain, often to the detriment of the website owner.

By using Joomla's HTTP Header plugin to control what content is being served to your visitors, you reduce the chances of hackers being able to serve malicious website content to your visitors via outdated vulnerable plugins. Which helps to stop malicious script injections on your website.

Well, not quite, because when you made your website 5 years ago, you installed the trendy Foo Bar Plugin to print "FOO BAR" on your home page. It looked cool to start with, but after a while you changed your mind and deleted the plugins fooFOO - BAR/bar shortcode from your homepage article.

Fast track to today, 5 years on, that plugin is still there, published and active on your website, but it's not been updated for 5 years because you've long since forgotten about the plugin, or the author stopped supporting it. Now, some nefarious fellow has realised this plugin has a security vulnerability that can be exploited to start a Cross Site Scripting (XSS) attack on your website, and make your unsuspecting visitors, victims.

Cross-site scripting, which is also known as XSS, is a security vulnerability in your website that allows an attacker to compromise the interactions that your users have with your now vulnerable website.

The attacker/hacker uses XSS to exploit your vulnerable website to send a malicious script to your unsuspecting user. Because the script has come from your website, your user's browser doesn't know or suspect that the script shouldn't be trusted and executes the script when the webpage loads and opens.

Malicious scripts run in this way can cause many problems for your user, from stealing login passwords and usernames data kept in cookies, to sending your user to fake phishing websites. Scripts can even change the appearance of the web page your website is serving and show you different advertising.

Using Joomla's HTTP Headers plugin helps to stop cross-site scripting by ensuring that only the scripts and content you want to serve to your visitor are actually served. Everything else gets blocked.

So, in the example above, you could've configured the HTTP Headers plugin to only serve your website's JavaScript (script) files from a specified folder, or maybe a CDN if you use one, to stop the attack.

You could also stop the website from running inline JavaScript that's embedded in the HTML. But, be aware that depending on how you've designed your website HTML, this could cause issues further down the line.

This would then help to stop malicious JavaScript code being executed on your website. Even if your vulnerable Foo Bar Plugin was to blame for a hacker being able to inject malicious code into your website in the first place.

Using Joomla's HTTP Plugin is relatively straightforward, although it may be a good idea before making changes to the default settings to gen-up on some of the special terms relating to its use. Although, in saying that, some of them should already be familiar to you.
