Pagination In Website Using Arrays / Php / Javascript Example Code

Hi, Pagination in a database based website is very much important in order to include all the entries in the web page.the following give a way to include pagination in your web page through Arrays

$result = mysql_query(“select * from tablename where conditions (optional)”);

if(mysql_num_rows($result)>0)

{$i=0 ;

while($row=mysql_fetch_array(result))

{
$array[$i][0]=$row["fieldname1"]; //fieldname reprsents the arrtibute name in the table
$array[$i][1]=$row["fieldname2"];
$array[$i][2]=$row["fieldname3"];
$array[$i][3]=$row["fieldname4"];
$array[$i][4]=$row["fieldname5"];
//place as much information to be displayed in the array here ‘a’

$i++;

}

}

$total_pages = mysql_num_rows($result);

echo “Total “.$total_pages.” results found”;

$targetpage = “your current page?parametes that you are sending from previous page”;

/*
Place code to connect to your DB here.
*/
//include(‘dbconnect.php’);    // include your code to connect to DB.

//$tbl_name=”Members”;        //your table name
// How many adjacent pages should be shown on each side?

$adjacents =1;

/*
First get total number of rows in data table.
If you have a WHERE clause in your query, make sure you mirror it here.
*/

//    $query = “SELECT COUNT(*) as num FROM $tbl_name”;
//    $total_pages = mysql_fetch_array(mysql_query($query));

//$total_pages[num];

/* Setup vars for query. */
//$targetpage = “pagination.php”;     //your file name  (the name of this file)

$limit = 5;                                 //how many items to show per page
$page = $_GET['page'];

if($page)
$start = ($page – 1) * $limit;             //first item to display on this page
else
$start = 0;                                //if no page var is given, set start to 0

/* Get data. */

/* Setup page vars for display. */
if ($page == 0)
$page = 1;                    //if no page var is given, default to 1.
$prev = $page – 1;                            //previous page is page – 1
$next = $page + 1;                            //next page is page + 1
$lastpage = ceil($total_pages/$limit);        //lastpage is = total pages / items per page, rounded up.
$lpm1 = $lastpage – 1;                        //last page minus 1

/*
Now we apply our rules and draw the pagination object.
We’re actually saving the code to a variable in case we want to draw it more than once.
*/

$pagination = “”;
if($lastpage > 1)
{

$pagination .= “<div class=\”pagination\”>”;
