Pozdrav svima. Ima neko ideju zasto ovaj skript ne odradi svoj posao kako treba. Tacnije dekrement $page-- ne radi. Sve radi ok osim toga. Jedino sto bi jos moglo da se resi je to da se na pocetku ne prikazuje uopste link "Prethodna".
$page = isset($_GET['page'])?intval($_GET['page']):0;
$per_page = 2;
$start = $page?$page*$per_page:0;
$next_link = '<a href="?page='.$page++.'">Prethodna</a>';
$prev_link = '<a href="?page='.$page--.'">Sljedeća</a>';
$sql="SELECT * FROM diplomci order by ID_DIPLOMCA asc LIMIT $start, $per_page;";
$result=mysql_query($sql);
$i=0;
while($red=mysql_fetch_array($result))
{
echo'<table border="0" width ="450"><tr align="left" ><td bgcolor= "#606D84" width="8%" align="center"><FONT SIZE="3" color="#FFFFFF"><b>'.++$i.'.</b></FONT></td><td align="right"><FONT SIZE="3"><a href="profil.php?idDiplomca='.$red['ID_DIPLOMCA'].'">Pogledaj profil</FONT></a></td><tr></table>';?>
<?php echo'<b>Ime: </b>'; echo '<b>'; echo $red['IME']; echo'</b>' ?> <br><?php echo '<b>Prezime: </b>'; echo '<b>'; echo $red['PREZIME']; echo'</b>'?><br><?php echo '<b>Odsjek: </b>'; echo '<b>'; echo $red['SMIJER']; echo'</b>'?><br> <?php echo '<b>Status: </b>'; echo '<b>'; echo $red['STATUS']; echo'</b>';?><hr>
<?php
}
//Broj redova u bazi
$count_sql = 'SELECT COUNT(*) FROM diplomci';
$count_result = mysql_query($count_sql);
$count = mysql_fetch_row($count_result);
$brojRedova = $count[0];
mysql_close();
$brojStrana=round($brojRedova/$per_page);
echo 'Ukupno ima '.$brojStrana. ' Strana';
if($page<$brojStrana-1)
{
echo "<div>$next_link $page $prev_link</div>";
}
else
{
echo "<div>$next_link $page</div>";
}

Zašto komplikovati? Napravi fajl paginacija.php i unesi sledeći kod:
$rowsperpage = $result_per_page;
$totalpages = ceil($numrows / $rowsperpage);
if (isset($_GET['page']) && is_numeric($_GET['page'])) {
$currentpage = (int)$_GET['page'];
} else {
$currentpage = 1;
}
if ($currentpage > $totalpages) {
$currentpage = $totalpages;
}
if ($currentpage < 1) {
$currentpage = 1;
}
if ($totalpages <= 1) {
$totalpages = 1;
}
$offset = ($currentpage - 1) * $rowsperpage;
if (isset($_GET['page']) AND is_numeric($_GET['page'])){
$current_page = ($_GET['page']);
}
if (!isset($current_page)) {
$current_page = 1;
}
$range = $max_links;
if ($range >= $totalpages) {
$range = $totalpages;
}
if ($current_page > $totalpages) {$current_page = $totalpages;}
echo '<table><tr><td style="padding-right:24px;" align="right" class="pagination"> <b>Strana ' . $current_page . ' od ' . $totalpages . '</b> [' . $numrows . ' ukupno ] ';
if ($currentpage > 1) {
echo " <a title= 'Prva strana' href='{$_SERVER['PHP_SELF']}?page=1'><<</a> ";
$prevpage = $currentpage - 1;
echo " <a title='Poslednja strana' href='{$_SERVER['PHP_SELF']}?page=$prevpage'><</a> ";
}
for ($x = ($currentpage - $range); $x < (($currentpage + $range) + 1); $x++) {
if (($x > 0) && ($x <= $totalpages)) {
if ($x == $currentpage) {
echo " [<b>$x</b>] ";
} else {
echo " <a href='{$_SERVER['PHP_SELF']}?page=$x'>$x</a> ";
}
}
}
if ($currentpage != $totalpages) {
$nextpage = $currentpage + 1;
echo " <a href='{$_SERVER['PHP_SELF']}?page=$nextpage'>></a> ";
echo " <a href='{$_SERVER['PHP_SELF']}?page=$totalpages'>>></a> ";
}
echo '</td></tr></table>';
?>
Zatim na samom početku (pre glavnog upita) kucaj:
$sql= 'SELECT COUNT(*) FROM diplomci LIMIT 1';
$result = mysql_query($sql);
$r = mysql_fetch_row($result);
$numrows = $r[0];
$result_per_page = 20; // 20 rezultata po strani
$max_links = 5; //Broj linkova pre i posle trenutne stranice
I glavni upit treba biti ovakav:
$sql="SELECT * FROM diplomci order by ID_DIPLOMCA asc LIMIT $offset, $rowsperpage;";
I samo "pozoveš" paginaciju gde hoćeš sa
include('paginacija.php');
P.S. Ne zaboravi da filtriraš nekom svojom metodom $_GET
Dopuna: 08 Dec 2010 9:12
Dodatak:
Ako hoćeš da stilizuješ paginaciju dodaj ovo u .css (već se koristi klasa class="pagination")
.pagination {
padding: 0px;
margin: 0px;
text-align:right;
}
.pagination a {
padding: 2px 3px 2px 3px;
margin: 1px;
border: 1px solid #AAAADD;
text-decoration: none; /* no underline */
color: #fff;
-moz-border-radius: 4px;
-webkit-border-radius: 4px;
}
.pagination a:hover, .pagination a:active {
border: 1px solid #105289;
color: #FFAA00;
}
.pagination span.current {
padding: 2px 5px 2px 5px;
margin: 2px;
border: 1px solid #105289;
font-weight: bold;
background-color: #105289;
color: #FFF;
}
.pagination span.disabled {
padding: 2px 5px 2px 5px;
margin: 2px;
border: 1px solid #EEE;
color: #DDD;
}
td.pagination {height: 24px;}
Eto...

Za nesto sto nije komplikovano, poprilicno dugacak kod 
Probaj ovako nesto:
<?php
function paging($rows,$per_page=10) {
$_GET['page'] = $_GET['page'] ? intval($_GET['page']) : 1;
$p = ceil($rows/$per_page);
if ($p > 1) {
if ($_GET['page'] > 1) {
echo "<a href='".$_SERVER['PHP_SELF']."?page=".(intval($_GET['page'])-1)."'><</a>\n";
}
echo "<a href='".$_SERVER['PHP_SELF']."?page=1'>1</a>\n";
$start = max(2,min($p-4,$_GET['page']-2));
$end = min($p-1,max($start+3,$_GET['page']+2));
for ($i=$start;$i<=$end;$i++) {
if (($start > 2) and ($start == $i)) {
echo "... ";
}
echo "<a href='".$_SERVER['PHP_SELF']."?page=".$i."'>".$i."</a>\n";
if (($end < $p - 1) and ($i == $end)) {
echo "... ";
}
}
echo "<a href='".$_SERVER['PHP_SELF']."?page=".$p."'>".$p."</a>\n";
if ($_GET['page'] < $p) {
echo "<a href='".$_SERVER['PHP_SELF']."?page=".(intval($_GET['page'])+1)."'>></a>\n";
}
}
}
?>
a prikazujes sa:
<?php
$rows = mysql_num_rows(mysql_query("SELECT ID_DIPLOMCA FROM diplomci_order"));
paging($rows,20);
?>
A upit za prikazivanje:
<?php
$limit = $_GET['page'] ? ((intval($_GET['page'])-1)*20).",20" : "0,20";
$q = mysql_query("SELECT * FROM diplomci_order ORDER BY ID_DIPLOMCA ASC LIMIT ".$limit);
?>

Zanimljiva paginacija. Samo ovaj kod za dobijanje rezultata:
$rows = mysql_num_rows(mysql_query("SELECT ID_DIPLOMCA FROM diplomci_order"));
treba da bude:
$sql= 'SELECT COUNT(ID_DIPLOMCA) FROM diplomci LIMIT 1';
To pravi bitnu razliku i daje bolje performanse.
Ipak je ova moja skripta mnogo fleksibilnija. Ima i fin offset (levo i desno) tako da trenutna strana uvek stoji u sredini. Lako se može napraviti AJAX paginacija sa ovom skriptom.
Evo primera (gornji linkovi) :
openstats.iz.rs/index2.php

Pokreni pa komentarisi  i moja ima takav prikaz, plus sto prikazuje samo 7 (ili manje) strana: prvu, dve ispred, onu na kojoj si, dve iza, i zadnju.

Ups, sry onda. Gledao sam samo kod na brzinu.
Mogao si da dodaš na primer još jednu varijablu kod paging funkcije. Na primer broj linkova pre i posle izabrane stranice...kao kod moje skripte.
function paging($rows,$per_page=10, $max_links = 5)
i samo zameniš kod za $start i $end sa $max_links.
Pr:
<< < 1 2 [3] 4 5 6 7 8 > >>

Pozdrav!
Dali mi možete reći kako da napravim da kad u linku paginacije ukucam localhost/paginacija.php?page=0
da mi neizbacuje grešku
You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '-2,2' at line 1
i da zaštitim od sql injectiona
Hvala!

Postovani forumasi, ima li neko da mi pomogne oko ove Paginacije. Rijec je o modulu u koji treba da ubacim kod za paginaciju. Nisam siguran gdje grijesim pa moze li pomoc od iskusnih. Treba mi ovo,

Kod je
