  2. Hi, I got a problem with pagination. I got a script but the problem is that I use the connection to database with "mysqli" NOT "mysql". Im newbe with mysqli and I dont know how can I change the pagination script to work. <?php $dbConnect= mysqli_connect('localhost', 'user', 'password') or die('Cant connect'); mysqli_select_db($dbConnect, 'database') or die('Cant connect to database'); mysqli_set_charset($dbConnect, "utf8"); ?> And this is a script for pagination <?php $limit = 4; $sql = "select count(c_vesti_id) from c_vesti"; $c = array_shift(mysql_fetch_row(mysql_query($sql))); $maxpage = ceil($c / $limit); $page = isset($_GET['page']) ? abs((int)$_GET['page']) : 1; if ($page <= 0) { $page = 1; } else if ($page >= $maxpage) { $page = $maxpage; } $offset = ($page-1) * $limit; $query = mysql_query("select * from c_vesti limit $offset, $limit "); while ($row = mysql_fetch_assoc($query)) { print $row['c_vesti_naslov']."<br />"; } // $linklimit = 4; $linklimit2 = $linklimit / 2; $linkoffset = ($page > $linklimit2) ? $page - $linklimit / 2 : 0; $linkend = $linkoffset+$linklimit; if ($maxpage - $linklimit2 < $page) { $linkoffset = $maxpage - $linklimit; if ($linkoffset < 0) { $linkoffset = 0; } $linkend = $maxpage; } if ($page > 1) { print "<a href='?page=".($page-1)."'>Back</a> "; } for ($i=1+$linkoffset; $i <= $linkend and $i <= $maxpage; $i++) { $style = ($i == $page) ? "color: black;" : "color: blue;"; print "<a href='?page=$i' style='$style'>[$i]</a> "; } if ($page < $maxpage) { print "<a href='?page=".($page+1)."'>Forward</a>"; } ?> Thanks in advanced for help T
