Use HTMLHelper::_ by calling a namespaced class

Question

In my component under Joomla! 4.0, I have the following call which returns:

error JHtml componentname not found.

HTMLHelper::_(
    'componentname.link',
    'index.php?option=com_component&view=credits',
    Text::_('COM_COMPONENT_MYTEXT'),
    '',
    '',
    '',
    ''
);

I have a namespaced class called ComponentName under Component\Name\Libraries\Html\Html. How can I make HTMLHelper find the namespaced class of my component?

Answer 1

HTMLHelper needs to be told where to search for custom classes, try adding HTMLHelper->addIncludePath('YOUR PATH') with the path to your component.

If you want you could load libraries/src/HTML/HTMLHelper.php and look around after line 126. That's where it goes looking for the custom class information.

It looks like you are attempting to make an href link, is this the case?

Answer 2

I have solved it by adding a class file under /site/src/Service/Html/Grid.php with the namespace Mycomponent\Forum\Site\Service\Html; in this class, I have some methods like published().

Then in the file /admin/src/Extension/MyComponent.php, I added the class into the boot method:

public function boot(ContainerInterface $container) 
{
    $this->getRegistry()->register('grid', new Grid($container->get(SiteApplication::class)));
}

Then I can call the method like:

HTMLHelper::_('grid.published', $row, $item->published, '', true);
