Het probleem is nu. Als ik op volgende klik dan krijg ik een witte pagina. De hij moet dan naar pagina book.php nextpage gaan.
Ziet iemand hier zo een knullige fout?
Notice: Undefined index: linkpage in
dat is;
Code (php)
1
2

<?php
$linkpage = $_GET['linkpage'];
?>
$linkpage = $_GET['linkpage'];
?>
Nummer 2;
Notice: Use of undefined constant num1 - assumed 'num1' in
Code (php)

<?php
$total_pages1 = $total_pages1[num1];
?>
$total_pages1 = $total_pages1[num1];
?>
Ik zie er niks fouts aan.

Bij de linkpage heb ik het volgende van gemaakt maar dat haalt ook niks uit
Code (php)
1
2

<?php
$pagination1.= "<a href=\"$targetpage1?linkpage=$next1\">Volgende »</a>";
?>
$pagination1.= "<a href=\"$targetpage1?linkpage=$next1\">Volgende »</a>";
?>
Maar dan krijg ik gelijk Notice: Undefined index: linkpage in bij de eerste $linkpage.
veranderd naar dit:
Zoals Gerhard al aangaf? Wat jij deed klopte namelijk niet.
Krijg je dan nog steeds de fout, zet dan dit even bovenaan zodat je weet wat er precies in je GET array zit:
