Custom Pagers Code Snippet

  • Drupal 6.x

...
Kp, irgendwie ist das Modul Custom Pagers (http://drupal.org/project/custom_pagers) ja echt simpel zu bedienen, aber ich such mir jedes mal wieder einen Wolf wie ich den Pager denn nun in meinem angepassten Template node-CONTENTTYPE.tpl.php einbette.

Stell ich mich irgendwie an, bin ich da der einzige? Egal, wie dem auch sei, hier mal der Code:

<?php
print $node->content['custom_pager_top']['#children'];
?>

Vielleicht hat ja wer Lust noch weitere Schnipsel dazuzuschreiben, damit funktioniert es jedenfalls auch super...

Hier gibt's auch noch ne Anleitung: http://www.drupalcenter.de/handbuch/6250

Da custom_pagers einen Block

Eingetragen von SteffenR@drupal.org (2262)

Da custom_pagers einen Block zurück liefert kannst du diesen auch direkt per module_invoke in die Seite einbinden..

Die Ausgabe im Inhaltstyp müsste dann wie folgt angepasst werden:

<?php
$pager = module_invoke('custom_pagers', 'block', 'view', 1);
print $pager['content'];
?>

Sauberer wäre es natürlich die "Sachen" über eine PreProcess Funktion in der template.php "laufen zu lassen" !

Hier eine einfache Beschreibung zur Nutzung des Custom Pagers Modules:

http://drupal.org/node/371358

Anschließend füge ich immer folgenden Code ein:

<?php
print $node->content['custom_pager_top']['#children'];
?>

Nur 10 Einträge

Leider zeigt das Custom Pagers Modul in der 6.x-1.10-beta1 nur 10 Einträge an.

Abhilfe schafft:

ich habe den custom pager

Eingetragen von fabi80 (112)

ich habe den custom pager auch installiert auf meinem lokalen System.
Dort läufts auch.

Wenn ich diesen auf meine Homepage online stelle, mit den gleichen Einstellungen sehe ich den Pager nicht mehr.

An was kann das liegen?

Danke.
