Chyba 500 Jhtml in Joomla4.X Topic is solved

[Studio555]

I am converting a component from J3.X to J4 and I have an unsolved problem for me. To display the date selection, the J3.X version displayed the code:

Code: Select all

  <?php if ($listek == 'denni'): ?>  
            <form action=""  class="hidden-print" name="dateRange" method="post">
            
            <?php echo JHtml::_('jidelnilistek.listmenus', $menuTypeId, 'menuId', $addItems ? $addItems->id : '', $js); ?>
                          
            </form>
            <?php endif;?>

This code used the file "Helpers/html/jidelnilistek.php" where the class "class jidelnilistek" and "public static function listmenus" were declared.

In version J4 this is not possible - error message: "500 JHtml jidelnilistek not found". I know that this part of the code will need to be refactored into HTMLHelpers, but I'm not entirely sure how. Any advice or help out there?

thank you for any advice

This should still be working in J5. You could file a bug report but don't hold your breath. The way going forward is to register the class with the service registry:

Code: Select all

use Joomla\CMS\HTML\HTMLHelper;

HTMLHelper::getServiceRegistry()->register('jidelnilistek', new YourServiceClass);

If the class is static, you can register it by name:

Code: Select all

HTMLHelper::getServiceRegistry()->register('jidelnilistek', YourServiceClass::class);

Thank you for answer.
I used this in "default.php" file

Code: Select all

HTMLHelper::getServiceRegistry()->register('jidelnilistek', new jidelnilistek);

As a result, it still doesn't find the class:
Class "jidelnilistek" not found

I assume that the file with the new class "jidelnilistek.php" will be in the directory "Helpers"

You have to load the class yourself. Modern J4+ components use namespaced classes with PSR-4 autoloading. If you haven't converted to this yet, you can use the old JLoader::register() method.

Thank you very much for your help. It's OK.
