Lapozás megoldva:
Tesztelve: Frog 0.9.5 RC2 alatt!
base_url - a lapozni kívánt oldal megnevezése
per_page - bejegyzések megjelenése oldalanként
num_links - hány oldal jelenlen meg
Ezt a kódrészt abba az oldalba helyezd el amit lapozni szeretnél:
<?php use_helper('Pagination');
$pagination = new Pagination(array(
'base_url' => 'oldalcim',
'total_rows' => $this->childrenCount(),
'per_page' => 10,
'num_links' => 8,
'cur_page' => (isset($_GET['page']) ? $_GET['page']: 1)
));
if ($pagination->total_rows > $pagination->per_page)
echo '<p><br />Oldalak: '.$pagination->createLinks().'</p>';
?>
Ezt a kódot ments el egy Pagination.php fájba és másold be a frog - helpers mappába. Amennyiben a Frog 0.9.5 RC2-t használod, az ott megtalálható (frog-helpers-pagination.php -t) írd felül ezzel.
