Hi,
every one it is quite easy when trying to get the limited number of records per page… i,e paging… wanna try?… LOOK AT THIS!…
copy and past the following that’s it…..:p
<?php
session_start();
//———————————————————————————————————————-
//connect to the database
$DBUserName = “root”; //database user account name
$DBPassword = “”; //database user account password
$DBName = “school_db”; //name of database
@$conn = mysql_connect(“localhost”,$DBUserName,$DBPassword) or die(‘<br />1-Cannot connect to the database at the moment.<br /><br />Please try again later.<br />’); //connect to mysql
@$isDbSelected = mysql_select_db($DBName, $conn) or die(‘<br />1-Cannot connect to the database at the moment.<br /><br />Please try again later.<br />’); //connect to the db
//———————————————————————————————————————-
$linesPerPage = 4; //number of lines to print per page
//check if a page link was clicked
if(isset($_GET[‘txtPgNum’]))
{
$_GET[‘txtPgNum’]; //txtPgNum comes from the page links
unset($
}
//check if either ‘previous’ or ‘next’ buttons were clicked
else if(isset($_GET[‘dir’]))
{
$direction = $
unset($_GET[‘dir’]);
$_SESSION[‘currPage’] + $direction;
if($_SESSION[‘currPage’] = 1;
if($_SESSION[‘totPages’]) $_SESSION[‘totPages’];
}
else //neither a page link or previous or next buttons were clicked. This must then be the first call to this page
{
$
//select all the records to work out max number of rows and number of pages needed
$query = ‘select * from school_tbl’;
$rs = mysql_query($query,$conn) or die(“<p>3-Server is busy.<br />Please try again later.</p>”);
$totRows = mysql_num_rows($rs); //total number of rows to display
if($totRows%$linesPerPage == 0)
$totPages = $totRows/$linesPerPage;
else
$totPages = round(($totRows/$linesPerPage)+0.5); //total number of pages required
mysql_free_result($rs);
$_SESSION[‘totRows’] = $totRows;
$
}
//calculate the first record number to retrieve from the DB for this page
$_SESSION[‘offset’] = ($*$linesPerPage)-$linesPerPage;
if($_SESSION[‘offset’] < 0) $
if($_SESSION[‘offset’] > $_SESSION[‘offset’] = $
//————————————————————
//Code to retrieve the rows to display on the current page

$query = ‘select
$rs = mysql_query($query,$conn) or die(“<p>3-Server is busy.<br />Please try again later.</p>”);
