Jetzt hätte ich gerne, dass es eine Übersicht vor den Bildergalerien gibt, die als einzelne Artikel in einer Kategorie angelegt werden, welche von jeder Bildergalerie die ersten Bilder anzeigt.
Ich habe das nun soweit gelöst:

if (!class_exists (gallery)){
class gallery {
... //Die oben angegebene Klasse
}
}
$articleListOptions = array("idcat" => 7, // Idcat (Muss angegeben werden)
"lang" => $lang, // Sprach id (optional), standard ist die aktive Sprache
"client"=> $client, // Mandant id (optional), standard ist der aktive Mandant
"start" => false, // Startartikel
"order" => "created", // Feldname nach dem sortier wird, siehe tabelle 'con_art_lang'

// Artikellisten Objekt erzeugen
$articleList = new ArticleCollection($articleListOptions);
while ($article = $articleList->nextArticle())
{
$gallery = new gallery();
}
?>
Wie kann ich nun automatisch die zwei Valuefelder für die Pfade (value 0 und 1) von den entsprechenden Artikeln auslesen? Im Inputbereich würde ich diese Angabe dann rausnehmen.
Kann mir dabei bitte mal jemand helfen, ich finde leider nicht mal die richtige Tabelle wo ich diese Angaben finden kann, bzw. kapiere ich die entsprechende Abfrage nicht.
Vielen Dank für Eure Hilfe!!!
