I am trying to fetch data from mysql and display them category wise with pagination. I am geting the category wise result but in pagination i am seeing duplicate result from second page onwards
Have a look at link:
When I click on the category it is working. But see the pagination. The last pages are blank. I want to display picture category wise. Suppose when i click on bridal it will display only bridal picture. I am having two tables i.e. category and album. In category I have id and cname and in the album I have id, cid, thumbnail, picture. The cid is coming from the category table and actually is the id of the category table
Here is the code
<?php
$query="SELECT * FROM `category` WHERE `id`='$_GET[cat_id]'";
$sql=mysql_query($query);
while($row=mysql_fetch_array($sql))
{
?>
<div class="container">
<h3><?="$row[cname]"; }?></h3>
<?php
//================paging============================================
if($_GET[page_no])
{
$page_no=$_GET[page_no];
}else{
$page_no=1;
}
if($_POST[page])
{
$upper_limit = $_POST[page];
}else{
if($_GET[upper_limit])
{
$upper_limit = $_GET[upper_limit];
}else
{
$upper_limit = 21;
}
}
$lower_limit = $upper_limit * ($page_no - 1);
$sql2="SELECT * FROM `album` WHERE `id`='$_GET[cat_id]'";
$res2=mysql_query($sql2);
$num=mysql_num_rows($res2);
$num_of_page = intval($num/$upper_limit);
if($num%$upper_limit!=0)
{
$num_of_page = $num_of_page + 1;
}
//==================================================================
$count=$lower_limit;
$c=1;
$sel = "SELECT * FROM `album` ORDER BY id DESC LIMIT $lower_limit , $upper_limit";
$res=mysql_query($sel);
$num=mysql_num_rows($res);
if($num!="")
{
$sel="SELECT * FROM `album` WHERE `cid`='$_GET[cat_id]'";
$tab=mysql_query($sel);
while($row1=mysql_fetch_array($tab))
{
print "<a class='fancybox-buttons' data-fancybox-group='button' href='admin/$row1[picture]'><img src='admin/$row1[thumbnail]' /></a> ";
$c++;
}
?>
<?php
//=======================================================================
$prev = $page_no - 1;
$next = $page_no + 1;
print "<center><TABLE >

if($page_no!=1)
{
print "<a href='gallery-cat-photo.php?page_no=$prev&upper_limit=$upper_limit'><font size='' color='#660066'>Previous</font></a> ";
}
for($i=1; $i<=$num_of_page; $i++)
{
