Jeder Kategorie ein eigenes Template zuweisen

Dieses Funktion ermöglicht es, dass man für jede Kategorie eine eigene single.php anlegen. Es wird die Kategorie-ID ausgelesen und dann kann man ganz einfach eine neue single.php erstellen in folgender Form: single-kategorie-ID.php was dann so ausschaut: single-3.php - dies wäre dann das Template was für alle Artikel genutzt werden würde diese in der Kategorie 3 sind. Falls keine spezielle single.php für einen bestimme Kategorie vorhanden ist wird die Standard single.php genutzt. Das ganze am besten in die functions.php im Themefolder.

<?php
	add_filter('single_template', create_function('$t', 'foreach( (array) get_the_category() as $cat ) { 
	if ( file_exists(TEMPLATEPATH . "/single-{$cat->term_id}.php") ) 
		return TEMPLATEPATH . "/single-{$cat->term_id}.php"; } return $t;' ));
?>

<?php 
 
    // Hole die Kategorieübersicht, aber zeige sie noch nich an (echo = 0)
    $kategorien = wp_list_categories('title_li=&show_count=1&echo=0');
 
    // Array, Inhalt: Suche nach diesen Stringmustern...
    $array_suchen = array('(', ')');
    // ...und ersetze sie durch diese
    $array_ersetzen = array('<span class="kleineschrift">// ', ' Einträge</span>');
 
    // str_replace durchführen
    $kategorien = str_replace($array_suchen, $array_ersetzen, $kategorien);
 
    // Output
    echo $kategorien;

Hallo,
Der Code scheint soweit zu funktionieren. Doch wenn ich im Backend auf “abmelden” klicke erhalte ich folgende Fehlermeldung:
