Hi all,,
I have created an front end which will display the list of items.....if the list of items exceeds ,
it elongates the page, but i want to limit it for the first page, if more number of items then it should be possible to display in the next page........how to do this
you want pagination.
check out a couple of scripts in the snippets section...

pagination is pretty popular, google 'php pagination' and you'll get several (paginated) pages of results to sift through.
this is the code for paging:
<?php
mysql_connect("localhost", "root", "1234");
mysql_select_db("image");
// how many rows to show per page
$rowsPerPage = 20;
// 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;
$query = "SELECT val FROM randoms LIMIT $offset, $rowsPerPage";
$result = mysql_query($query) or die('Error, query failed');
// print the random numbers
while($row = mysql_fetch_array($result))
{
echo $row['val'] . '<br>';
}
echo '<br>';
// how many rows we have in database
$query = "SELECT COUNT(val) AS numrows FROM randoms";
$result = mysql_query($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> ";
}
}
// creating previous and next link
// plus the link to go straight to
// the first and last page
if ($pageNum > 1)
{
$page = $pageNum - 1;
$prev = " <a href=\"$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;
$next = " <a href=\"$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
