The development strategy for the Joomla CMS is currently being revised. There is going to be at least a 3.3 and a 3.4 and probably more incremental minor versions at irregular intervals. This is different from the previous pattern where we'd go 3.5 and then 4.0 six months apart. It's not known when 4.0 will be released but my guess is it's not going to be ...
Joomla 3.9.x has a file public_html/libraries/classmap.php that contains all the old style Class names, and the new replacements. E.g.
JLoader::registerAlias('JFactory', '\\Joomla\\CMS\\Factory', '5.0');
JFactory is indeed deprecated. You can rewrite
// JFactory is deprecated
$db = JFactory::getDbo();
// Put at the top of your file
1) JHtml is an alias for Joomla\CMS\HTML\HTMLHelper class. You'll have to start using the real class sooner or later because the alias will not exist in Joomla! 5.0. To use the real class you have to either import it:
Or use fully qualified class name:
You need to wait for 3.10.X to become available; as per the documentation, "This guide assumes you are starting on Joomla 3.10.x. If you are on a earlier version make sure you upgrade to Joomla 3.10 first before moving to Joomla 4."
Joomla 3.10 is currently in development, at 86% completion, most notably, with no completion date for release. V3.10-...
I’m answering the question because it is obviously not a Joomla 4 core bug but a mistake in the developer’s coding and the problem would be the same in Joomla 3 too.
If you try to use a Joomla core class in your code you have to include that class on the top of the file otherwise Joomla does not know what it needs to use, so:
In Joomla 4 we've completely removed the Mootools library and any API functions for it. If you'd like to utilise a modal, you can use JHtmlBootstrap::renderModal which is currently a wrapper for Bootstraps JS modal component, however we're rewriting the main components as custom elements.
Here is an example for you to build on top of:
// Add this to the ...
To get Menu item in Joomla 4 you can get the Item From the Factory like
$menu = Factory::getApplication()->getMenu();
$active = $menu->getActive();
getActive() will give the curent Menu Item, you can use other methods getDefault() or getItem() as per your need.
You can get Menu items with menu type as
$items = $menu->...
Your comment led me to doubt my belief that getDbo() is alive and well. I have tested my below techniques on Joomla3.9.5 and there are no problems.
Based on this documentation:
Returns the global \JDatabaseDriver object, only creating it if it doesn't already ...
Either, include that helper class on the top of your default.php like:
defined('_JEXEC') or die;
Then you can use that class within your default.php file
Or standardly define your own variable in mod_articles_latest.php like:
$myStuffHere = ArticlesLatestHelper::myCustomFunction($myparam)...
Finally figured it out - my problem is a missing placeholder in the tmpl (which was not required for JSubMenuHelper). Added this to my tmpl/default.php, now it works:
<div id="j-sidebar-container" class="span2">
<?php echo $this->sidebar; ?>
The submenu in banners I was wondering about is actually done via the manifest file, ...
The call method has been marked as removed for Joomla 4.0, as it's simply a wrapper for get().
You don't need to manually store the cache as this is done within the get() method:
According to the documentation, JApplicationWeb seems to be alive and well in Joomla4.
note As of 4.0 this class will be abstract
Relevant references and examples:
This should still work in 4.0 but will break in 5.0. You are advised to use fully qualified class names. Remove JLoader::register() call and instead add a use statement:
Thanks to @Zollie-- the plugin is enabled by default and does seem to work. You'd need to check the libraries/autoload_psr4.php to verify that your component's namespace (set in the new namespace parameter in the manifest xml) is being generated correctly.
The default namespace format for custom components is DeveloperName\Component\ComponentName.
In the Joomla Extension Directory there is a free OTP plugin for Joomla available that uses an external commercial SMS (Text message) provider:
OTP Verification For Joomla
Maybe you can use the plugin + its SMS provider as solution, or use the code to develop your own Firebase OTP plugin?
Just an FYI that Joomla 3.10-alpha has now been released so the upgrade process can now easily done.
Go to the Joomla Update Component Options and switch the Update Channel to Testing and the Minimum Stability option to Alpha.
Update to 3.10 alpha1 using the Joomla Update Component.
After you have updated to 3.10 alpha please switch the Update
The view file that your component is looking for MycomponentViewViewname which was used in the Joomla 3, so make sure you are extending the right controller class in your Controller(i.e Joomla\CMS\MVC\Controller\BaseController or any other class extending it such as AdminController). If it is from correct namespace track the setView() for any such changes ...
You will firstly need to create a helper class that extends ContentHelper, like so:
class MyComponentHelper extends ContentHelper
protected $config = null;
public function __construct($config)
$this->config = new ...
Ok, my bad… I forgot to put this code inside mod_xxxxx.php…
if ($params->def('prepare_content', 1))
$module->content = HTMLHelper::_('content.prepare', $module->content, '', 'mod_xxxxx.content');
Ok, this is a bit hack-ish, but it can work:
Set article0 as a category itself, not as an article. Use the Category Description field to hold what you currently have as the article text.
Set article1-100 as articles in the category. That way /article0 is the category (Blog or List) page, and the rest are /article0/articlex as articles within that category....
To implement Joomla standard namespacing in a plugin, follow these steps:
First, declare extension's namespace in manifest file:
If you are editing files on site, you need to delete libraries/autoload_ps4.php file so it can regenerated. If you update the plugin using extension manager, this ...
It would be very difficult but it could be done if you wanted to write enough code.
The values for each setting are stored in the params field for each instance of the module in the #__modules table. As it is possible to have more than one instance of a module your code would need to handle this to make sure you are updating the right module or all of ...
Sets a value to $hascontent if either of the conditions on the right side is true. The conditions appear to be is the module empty or is customContent set, i.e. not null.
If you want to find out what the value is that is set then use the following to display it.
The view is created from the code in ..\administrator\components\com_menus\views\item\tmpl starting with edit.php and your particular tab would be edit_modules.php
I got there by decoding your URL, administrator/index.php?option=com_menus&view=item&client_id=0&layout=edit&id=101 and knowing it would be under /components and /tmpl
It does ...
You will need to download and install Composer first.
Once done, open your terminal, navigate to the root of your Joomla installtion, and type in the following command:
You'll then need to install NodeJS.
Once installed, in the same terminal, run the following command:
These commands will fetch all the Joomla PHP dependencies, ...
Your issue comes solely from confusion about Joomla! versions. These facts should clear the air:
\Joomla\CMS\Factory::getDbo() is deprecated in 4.0 and will be removed in 5.0. It is alive and well in 3.9.
\Joomla\CMS\Factory::getContainer() doesn't exist in 3.9 as it was only added in 4.0.
The code you were looking at is from 4.0, not from 3.9.5.
define('JPATH_BASE', __DIR__ . '/../../..');
require_once JPATH_BASE . '/includes/defines.php';
require_once JPATH_BASE . '/includes/framework.php';
// Boot the DI container.
$container = \Joomla\CMS\Factory::getContainer();
// Alias the session service key to the web session service.
