Pagination using php and mysql with jquery and ajax

                      You can display values with pagination using php. But you have to pass the page number and also relevant values through url. So your url look like this:

                                   pagination.php?p=2

                      The good php website should be contain good url strucutre. Thats why you alter the urls using .htaccess. You don't need to show passing values in url. It can be hidden by .htaccess. If you don't know, just visit Redirect urls using htaccess
                      So you need ajax and jquery to pass the values. Already you know the basic pagination concept. Otherwise, please visit Pagination using php and mysql


 Pagination using juery and ajax:


                       You need small function which is called by onclick event to display values with pagination in php. The jquery function as follows as:

<script type="text/javascript">
   function page(e) {
         $.ajax({
                       url:'pagination.php',
                       data:{p:e},
                       dataType:'html',
                       Type:'post',
                       success:function(e) {
                          $('#page').html(e);
                           }
                      });
                  }
</script>
   
         Where,
                     - function page(e){} is called from click event.
        ie, <a onclick="return page('.$i.')">'.$i.'</a>            
                    
                     - e is a page number passed from click event.
                     - pagination.php is name of this php file.
                      You define the url, data, dataType and type in ajax post to pass the values.


The overall php script for pagination: 


<html>
<body>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>
<div id='page'>
<?php
error_reporting('E_ALL ^ E_NOTICE');
mysql_connect('localhost','root','') or die(mysql_error());
mysql_select_db('new') or die(mysql_error());
$page=$_REQUEST['p'];
$limit=10;
if($page=='')
{
 $page=1;
 $start=0;
}
else
{
 $start=$limit*($page-1);
}
$query=mysql_query("select * from table1 limit $start, $limit") or die(mysql_error());
$tot=mysql_query("select * from table1") or die(mysql_error());
$total=mysql_num_rows($tot);
$num_page=ceil($total/$limit);
echo'<table><th>Reg.Id</th><th>Name</th><th>Category</th>';
while($res=mysql_fetch_array($query))
{
  echo'<tr><td>'.$res['game_ID'].'</td><td>'.$res['game_Title'].'</td><td>'.$res['category_Name'].'</td></tr>';
}
echo'</table>';
function pagination($page,$num_page)
{
  echo'<ul style="list-style-type:none;">';
  for($i=1;$i<=$num_page;$i++)
  {
      if($i==$page)
      {
         echo'<li style="float:left;padding:3px;">'.$i.'</li>';
      }
        else
     {
       echo'<li style="float:left;margin-                 left:4px;background:rgb(170,177,35);padding:4px;cursor:pointer;border:1px solid darkgreen ;"><a  onclick="return page('.$i.')">'.$i.'</a></li>';
      }
   }
  echo'</ul>';
}
if($num_page>1)
{
 pagination($page,$num_page);
}
?>
<script type="text/javascript">
function page(e) {
$.ajax({
url:'pagination.php',
data:{p:e},
dataType:'html',
Type:'post',
success:function(e){
   $('#page').html(e);
  }
});
}
</script>
</div>
</body>

</html>


You'll get output like like this:

pagination using php and jquery with ajax

                     Now you can paginated to next page. The url structure of your website should be fine.

Note:
             For pagination, you need any jquery reference like:
" <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script> "
