Mam problem z uzyskaniem liczby artykułów z konkretnej kategorii z mojego modułu niestandardowego? Czy ktoś mógłby skierować mnie we właściwym kierunku, której funkcji powinienem użyć?
Używam następujących:
$model = JModelLegacy::getInstance("Articles", "ContentModel");
$model->setState("filter_fields.catid", 16);
$articles = $model->getItems();
Ale zwracane są tylko następujące elementy:
object(ContentModelArticles)[134]

0 dla odpowiedzi № 1Zmieniłem kod na następujący:
$model = JModelLegacy::getInstance("Articles", "ContentModel");
$model->setState("filter.category_id", 16);
$articles = $model->getItems();
$num_articles = count($articles);
