In Joomla können Beiträge als "Haupteinträge" markiert werden. Einen speziellen Menütyp kann verwendet werden, um sie anzuzeigen und auch in das Beiträge - Modul können sie eingesetzt werden. Allerdings in einem Kategorieblog werden sie zusammen mit regulären Beiträgen angezeigt.
Kategorieblogs erlauben zudem die Definition von "Führenden" Beiträgen, die von den "Einleitungs" Beiträgen abgegrenzt werden. Die Sortierung dieser "Führenden" basiert jedoch ausschließlich auf der Reihenfolge der Beiträge. In einigen Fällen ist dies akzeptabel, bespielsweise, wenn die Beiträge nach Erstellungsdatum sortiert werden, wodurch die drei neuesten Beiträge automatisch als "Führende" angezeigt werden.
Was wenn ein spezifischer Beitrag fixiert als "Führende" dargestellt werden soll? Da fängt man an zu tricksen ... Die manuelle Sortierung, um sicherzustellen, dass ein bestimmter Beitrag stets an erster Stelle angezeigt wird, kann schnell umständlich und fehleranfällig werden. Daher entstand die Idee, "Haupteinträge" und "Führende" Beiträge in einem Override miteinander zu kombinieren.
Ich erstelle eine Kopie der blog.php Datei innerhalb meines Templates (z.B. in Cassiopeia unter templates/cassiopeia/html/com_content/category) und trenne die "Haupteinträge" (als featured gespeichert) von den anderen:
// Separate featured from normal articles
$leadingCount = (int) $this->params->get('num_leading_articles', 0);
$introCount = (int) $this->params->get('num_intro_articles', 0);
$linkCount = (int) $this->params->get('num_links', 0);
$featured = [];
$normal = [];
foreach ($this->items as $item) {
if ($item->featured == 1) {
$featured[] = $item;
} else {
$normal[] = $item;
}
}
$myLeadItems = array_slice($featured, 0, $leadingCount);
$featuredOverflow = array_slice($featured, $leadingCount);
$introPool = array_merge($featuredOverflow, $normal);
$myIntroItems = array_slice($introPool, 0, $introCount);
$linkPool = array_slice($introPool, $introCount);
$myLinkItems = array_slice($linkPool, 0, $linkCount);An der Stelle wo normalerweise die "Führende" Beiträgen angezeigt werden, ändere ich den Code um die "Haupteinträge" zu laden:
<?php if (!empty($myLeadItems)) : ?>
<div class="com-content-category-blog__items blog-items items-leading <?php echo $this->params->get('blog_class_leading'); ?>">
<?php foreach ($myLeadItems as &$item) : ?>
<div class="com-content-category-blog__item blog-item">
<?php
$this->item = &$item;
echo $this->loadTemplate('item');
?>
</div>
<?php endforeach; ?>
</div>
<?php endif; ?>Und weiter unten wo normalerweise die "Einleitung" Beiträge dargestellt werden, lade ich jetzt die "normalen":
<?php if (!empty($myIntroItems)) : ?>
<?php $blogClass = $this->params->get('blog_class', ''); ?>
<?php if ((int) $this->params->get('num_columns') > 1) : ?>
<?php $blogClass .= (int) $this->params->get('multi_column_order', 0) === 0 ? ' masonry-' : ' columns-'; ?>
<?php $blogClass .= (int) $this->params->get('num_columns'); ?>
<?php endif; ?>
<div class="com-content-category-blog__items blog-items <?php echo $blogClass; ?>">
<?php foreach ($myIntroItems as $key => &$item) : ?>
<div class="com-content-category-blog__item blog-item">
<?php
$this->item = &$item;
echo $this->loadTemplate('item');
?>
</div>
<?php endforeach; ?>
</div>
<?php endif; ?>

Diese Anpassung ermöglicht es, innerhalb einer Kategorie "Haupteinträge" zu definieren und sie als "Führende" Beiträge im Bloglayout anzuzeigen.
