It already exists

Thank you @brianteeman
Will inform and check it.

The Article Order field changes the order of the articles in the list, not the order of the years in the filter

Then I misunderstood

"How can I change the sorting of the year (appears first 2011 and not 2025")?

I just checked and by default the filter appears that way

As mentioned above, it would be possible with an override. An idea from Viktor Vogel's @Kubik-Rubik

Would it be good to be able to implement it?

`<?php $html = $this->form->yearField;

preg_match('/<option value=""[^>]*>' . Text::_('JYEAR') . '</option>/', $html, $placeholderMatch);
preg_match_all('/(\d{4})</option>/', $html, $yearMatches, PREG_SET_ORDER);

$years = [];

foreach ($yearMatches as $match) {
$years[] = [
'value' => $match[1],
'html' => $match[0],
];
}

usort($years, fn($a, $b) => $b['value'] <=> $a['value']);

$placeholder = $placeholderMatch[0] ?? '';
$optionsSorted = array_map(fn($y) => $y['html'], $years);

$selectYear = '' . "\n"; $selectYear .= ' ' . $placeholder . "\n"; $selectYear .= ' ' . implode("\n ", $optionsSorted) . "\n"; $selectYear .= '';

echo $selectYear; ?>`

Sorry, I wanted to paste the above into a code field...

Info from @Kubik-Rubik

If you want to implement this correctly in the core, you either have to intervene in the HtmlView (components/com_content/src/View/Archive/HtmlView.php) or, even better, in the corresponding model for the years (\Joomla\Component\Content\Site\Model\ArchiveModel::getYears)

if @Kubik-Rubik wants to submit a PR then he should do that.

Hey 👋 can I work on this issue

@Klath123 sure, you are welcome :) We do not assign issues, everyone can make a PR.

This feature is already implemented in Joomla!

The year sorting parameter already exists. To change the year order from oldest-first (2011, 2012...) to newest-first (2025,2024...):

1. Go to Menus → Menu Items
2. Edit your "Archived Articles" menu item
3. In the Archive Options tab, find "Year Filter Order"
4. Change from "Ascending" to "Descending"
5. Save
   This will show 2025 first instead of 2011, solving the original request.

The feature exists in default.xml as the year_order parameter and is implemented in ArchiveModel::getYears().

In the default.xml is not the year_order parameter. Show in
https://github.com/joomla/joomla-cms/blob/5.3.2/components/com_content/tmpl/archive/default.xml
https://github.com/joomla/joomla-cms/blob/6.0-dev/components/com_content/tmpl/archive/default.xml
and also in
https://github.com/joomla/joomla-cms/blob/5.3.2/components/com_content/src/Model/ArchiveModel.php#L149-190
I think you use a core-hack

@Aashish-Jha-11
To what Joomla version do you refer. I just checked on a 5.3.2, but I wasn't able to identify the "Year Filter Order".

Examplecode for Feature Request:

In /components/com_content/tmpl/archive/default.xml insert at Line #100:

 <field
				name="filter_field_years"
				type="list"
				label="JYEAR"
				default="ASC"
				validate="options"
				>
				<option value="ASC">JGLOBAL_OLDEST_FIRST</option>
				<option value="DESC">JGLOBAL_MOST_RECENT_FIRST</option>
			</field>

https://github.com/joomla/joomla-cms/blob/5.3.2/components/com_content/tmpl/archive/default.xml#L100

and in /components/com_content/src/Model/ArchiveModel.php change to:

/**
     * Gets the archived articles years
     *
     * @return   array
     *
     * @since    3.6.0
     */
    public function getYears()
    {
        $db        = $this->getDatabase();
        $nowDate   = Factory::getDate()->toSql();
        $query     = $db->getQuery(true);
        $queryDate = QueryHelper::getQueryDate($this->state->params->get('order_date'), $db);
        $years     = $query->year($queryDate);
        $filter_years =  $this->state->params->get('filter_field_years' , 'ASC');
        $query->select('DISTINCT ' . $years)
            ->from($db->quoteName('#__content', 'a'))
            ->where($db->quoteName('a.state') . ' = ' . ContentComponent::CONDITION_ARCHIVED)
            ->extendWhere(
                'AND',
                [
                    $db->quoteName('a.publish_up') . ' IS NULL',
                    $db->quoteName('a.publish_up') . ' <= :publishUp',
                ],
                'OR'
            )
            ->extendWhere(
                'AND',
                [
                    $db->quoteName('a.publish_down') . ' IS NULL',
                    $db->quoteName('a.publish_down') . ' >= :publishDown',
                ],
                'OR'
            )
            ->bind(':publishUp', $nowDate)
            ->bind(':publishDown', $nowDate)         
            ->order('1 '. $filter_years);
        $db->setQuery($query);
        return $db->loadColumn();
    }

Better language strings can also built in.

Thank you for the feedback.
I checked again and you are correct: the "Year Filter Order" parameter is not present in Joomla 5.3.2 core.
My earlier reply was based on a local modification (core-hack) or a future/experimental branch.

This feature is not yet available in the official Joomla release.
The example code provided by Sieger66 is a good starting point for a PR to add this functionality Will Implement it soon and raise a PR.

Closing, see PR #45841
