Ragazzi stavo leggendo la pillola presente sul forum e mi sono adoperato per adeguare il codice alle mie esigenze:
ho creato il file .class
e poi nella pagina che estrae i risultati ho messo:codice:class _makePager { var $limit; var $page; var $numPages; var $offset; var $sql; var $menu; function _makePager ( $limit ) { $this->limit = $limit; } function _getPagerData ( $numHits, $page ) { $numHits = (int) $numHits; $this->limit = max((int) $this->limit, 1); $this->page = (int) $page; $this->numPages = ceil($numHits / $this->limit); $this->page = max($this->page, 1); $this->page = min($this->page, $this->numPages); $this->offset = ($this->page - 1) * $this->limit; $this->sql = " LIMIT ".$this->offset.", ".$this->limit; $this->_makeMenu(); } function _makeMenu () { if ($this->numPages>1) { if ($this->page>1) $this->menu['PREVIOUS'] = ($this->page-1); for ($i=1; $i<=$this->numPages; $i++) { if ($i == $this->page) $this->menu['PAGES'][] = array ( 'ID' => $i, 'STATUS' => false ); else $this->menu['PAGES'][] = array ( 'ID' => $i, 'STATUS' => true ); } if ($this->page<$this->numPages) $this->menu['NEXT'] = ($this->page+1); } } function _getUri ( $_pagevar ) { $_getvars = $_SERVER["QUERY_STRING"]; $_url = $_SERVER["PHP_SELF"]."?"; $_getvars = explode( "&", $_getvars ); for ($i=0; $i!=count($_getvars); $i++) { list ($key, $value) = explode( "=", $_getvars[$i] ); if (($key)&&($value)) if ($key!=$_pagevar) $_url.= "{$key}={$value}&"; } return "{$_url}{$_pagevar}="; } }
Se testo questa pagine esce l'errore: Call to undefined function: _getpagerdata()Codice PHP:<?
require_once("php.sql.pager.class");
$_PAGER = new _makePager(2);
include("top_foot.inc.php");

$db = mysql_connect($db_host, $db_user, $db_password);

$_sql = mysql_query("SELECT * FROM prodotti ORDER BY marca {$_PAGER->sql}");
while ($row = mysql_fetch_row($_sql)) {

echo "$row[marca]";
}
if ($_PAGER->menu['PREVIOUS']) echo "<a href=\"".$_PAGER->_getUri("p").$_PAGER->menu['PREVIOUS']."\">pagina precedente</a>";

}
if ($_PAGER->menu['NEXT']) echo "<a href=\"".$_PAGER->_getUri("p").$_PAGER->menu['NEXT']."\">pagina successiva</a>";
mysql_close($db);
foot();
?>
