Result Set Limit and Navigation problem

saikiran · August 11, 2006

hi,

I am running a photo gallery in my site. in which , i am having a thumbnail page and a popup image page,

what i am doing is when user clicks the thumbnail, the bigger picture should open in a popup in a separate page.

I would like to add a navigation link in the popup page. i.e. with in the popup page, user can go and view the rest of the images in the gallery also.

[color=red]i am providing this as 1,2 ,3,4,5.....[Next][Previous] . format.

i am not able to run the navigation part properly....[/color]

This is what the code for the 2 pages:

[color=red]Thumbnails page code [/color]

[code]<?php include_once('config.php');
$psql = "select * from bhakt_photo";
$result = mysql_query($psql);

if($result)
{
while($row = mysql_fetch_array($result,MYSQL_BOTH))
{
echo "<table>";
echo "<tr>";
echo "<td>";?>
<a href='bhakti_popnew.php?id=<?php echo $row['id'];?>'><img src="http://www.seher.in/gall_upload/ <?php echo $row['mid_img'];?>" border="0" ></a>
<?php
echo "</td>";
echo "</table>";
}
}

?>
[/code]

-----Popup page code-------------

[code]<?php include('config.php');
//new code

$id=$_GET['id']; //this the Id i am getting for the images

// how many rows to show per page

$rowsPerPage = 1;

// by default we show first page

$pageNum = 1;

// if $_GET['page'] defined, use it as page number
if(isset($_GET['page']))
{
$pageNum = $_GET['page'];
}

// counting the offset
$offset = ($pageNum - 1) * $rowsPerPage;
//$offset = $rowsPerPage;

$query = " SELECT * FROM bhakt_photo where id=$id " .
" LIMIT $offset, $rowsPerPage";

echo $query."<br>" ;

$result = mysql_query($query) or die('Error, query failed');

?>
<body leftmargin="0" topmargin="0" marginwidth="0" marginheight="0">

<?php
while($row = mysql_fetch_array($result))
{
echo $row['big_img'];
} ?>
</table>
<br>
<br>
<?php // how many rows we have in database

$query = "SELECT COUNT(big_img) AS numrows FROM bhakt_photo ";

$result = mysql_query($query) or die('Error, query failed');
$row = mysql_fetch_array($result, MYSQL_ASSOC);
$numrows = $row['numrows'];

// how many pages we have when using paging?
$maxPage = ceil($numrows/$rowsPerPage);

// print the link to access each page
$self = $_SERVER['PHP_SELF'];
$nav = '';

for($page = 1; $page <= $maxPage; $page++)
{
if ($page == $pageNum)
{
$nav .= " $page "; // no need to create a link to current page

}
else
{
$nav .= " <a href=\"$self?page=$page\">$page</a> ";

}
}
if ($pageNum > 1)
{
$page = $pageNum - 1;
$id = $id-1;

$prev = " <a href=\"$self?page=$page&id=$id\">[Prev]</a> ";
$first = " <a href=\"$self?page=1&id=$id\">[First Page]</a> ";

//$prev = " <a href=\"$self?page=$page\">[Prev]</a> ";
//$first = " <a href=\"$self?page=1\">[First Page]</a> ";
}
else
{
$prev = ' '; // we're on page one, don't print previous link
$first = ' '; // nor the first page link
}

if ($pageNum < $maxPage)
{
$page = $pageNum + 1;
$id = $id +1;

echo "<b>". $id."<br>";

$next = " <a href=\"$self?page=$page&id=$id\">[Next]</a> ";
$last = " <a href=\"$self?page=$maxPage&id=$id\">[Last Page]</a> ";

//$next = " <a href=\"$self?page=$page\">[Next]</a> ";
//$last = " <a href=\"$self?page=$maxPage\">[Last Page]</a> ";
}
else
{
$next = ' '; // we're on the last page, don't print next link
$last = ' '; // nor the last page link
}

// print the navigation link
echo $first . $prev . $nav . $next . $last;

// and close the database connection

// ... and we're done!
?>[/code]

the problem what i assume is - the 'id' value is not passing in the subsquent pages properly.

i have checked readymade photogallery packages...but i would like to have my own. I am not an expert in PHP too.

can anyone just tell me whats the problem in my code and help me out in completing this one.

cheers

<?php include_once('config.php');

$result = mysql_query($psql);

if($result)
{
while($row = mysql_fetch_array($result,MYSQL_BOTH))
{
echo "<table>";
echo "<tr>";
echo "<td>";?>
[b]<a href="javascript:;" onClick = "window.open('bhakti_popnew.php?id=<?php echo $row['id'];?>','Gallery','height=700,width=589,scrolling=yes')"><img src="http://www.seher.in/uploads/<?php echo $row['mid_img'];?>" border="0" ></a>[/b]
