RELATEDX

{RELATEDX:Listenzähler : Schlüsselwörter : Kategorie-ID}

Erweitert von KH (flip-flop) 15.03.09

Docu: http://www.phpwcms-docu.de/link_tags_.phtml

Forum: –

Tag: {RELATEDX:Listenzähler : Schlüsselwörter : Kategorie-ID} ist ein “ausgeschnittener Programmteil aus dem System frontend” erweitert um die Möglichkeit unterhalb einer vorgegebenen Ebene mit der Suche zu beginnen. Dies ist sehr vorteilhaft z.B. für mehrsprachige Seiten.

Bis zur Version 1.21 dürfen die zu durchsuchenden Kategorien in denen die Artikel liegen nicht versteckt sein, ab der Version 1.3 kann dies im Script eingestellt werden.

Die Formatierung und Sortierung wird im Bereich // related articles based on keywords in der Datei config/phpwcms/conf.template_default.inc.php eingestellt.


Dateiname: rt_relatedx.php

Ort: /template/inc_script/frontend_render/rt_relatedx.php

Bedingung: $phpwcms['allow_ext_render'] = 1;/config/phpwcms/conf.inc.php




Bitte immer alle Felder ausfüllen: Z.B.

  • {RELATEDX:0:tip,top,flip,flop:0}die Suche nach den Schlüsselwörtern in Artikeln beginnt unterhalb der Kategorie-ID=0 = home
  • {RELATEDX:5:tip,top,flip,flop:2}Ausgabe der ersten fünf Einträge, mit der Suche nach den Schlüsselwörtern in Artikeln beginnend untehalb der Kategorie-ID=2

Z.B.:

Gegebene Struktur:

------------------------------------
L  E  V  E  L
.:  :  :  :
.0  1  2  3   <- LEVEL-Nr.
.:  :  :  :

{RELATEDX:5:tip,top,flip,flop:2} → Ausgabe: Der Title-Link der ersten fünf sichtbaren Artikel, unterhalb der nicht versteckten category_02 (ID=2), in denen die Schlüsselwörter vorkommen. (“nicht versteckten” siehe Hinweis oben und V1.3).


V 1.0

20.01.11 KH Update: Fehler korrigiert

Bitte spätestens ab r400 die Version 1.1 verwenden!!

Um diese Funktion zu aktivieren sind zwei Möglichkeiten vorhanden:

  • Im Script innerhalb des Bereichs “CUSTOM VAR” die Variable $date_form mit entsprechender php-Datumsnotation füllen.
  • In der Datei conf_template_default.inc.php eine Variable $template_default['related']['date_format'] anlegen und mit entsprechender php-Datumsnotation füllen.
