mae_event_categories ->die Kategorien ausgeben im Template/HTML

Hallo,
ich möchte gerne den/die Namen der Kategorie von mae_event_categories ausgeben, und würde mich freuen wenn ich etwas Hilfestellung bekomme,
Ich gestehe diesen Code, den es schon sehr lange gibt, weis nicht mehr woher, nur das nicht selber geschrieben habe, glaube aber in Etwa verstanden zu haben das da passiert :eek:,

Also, dieser folgende code im Template gibt den Titel des Eventkalenders im HTML aus:

Code:

---

Mein wunderbares Event: <?php $this->import('Database'); $result = $this->Database->prepare("SELECT * FROM tl_calendar WHERE id='$this->pid'")->execute(); ?> <?php echo $result->title; ?>

---

Ergibt: Mein wunderbares Event: "Freude Friede Eierkuchen"


Nun habe ich versucht diesen Code mit meinen rudimentären Kenntnissen zu Modifizieren um den Namen der Kategorie von mae_event_categories auszugeben, doch garnis erscheint:

Code:

---

Kategorie: <?php $this->import('Database'); $result = $this->Database->prepare("SELECT * FROM tl_mae_event_cat WHERE id='$this->pid'")->execute(); ?> <?php echo $result->title; ?>

---

Es gibt mehrer Kategorien, daher vermute ich das ich eine array Abfrage machen müsste?
:o ???

Doch wie macht man das fragt dtptiger.


Das folgende ist die dca von mae_event_cat, aus der ich vermute die Infos zu entnehmen sind um eine Arrayabfrage zu machen, oder?

PHP-Code:
