page numbering problem

**sedna** · Mar 30, 2007, 10:43

hey all,

i have serached for page numbering but from the tutorials my situration is different basicly i have 12 results stored in my hacks table in the database and i would like to limit 10 results per page so you should have 2 pages and when more data gets added to the database so more pages will be shown. anyways that does not appaer to happen

here is my code

PHP Code:


<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml">

<head>

<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />

<title>Hacks</title>

</head>



<body>

<table width="50%" border="0" cellspacing="0" cellpadding="3" align="center" >

<tr>

<th align="center">Hack Name</th>

<th align="center">Description</th>

<th align="center">Version</th>

<th align="center">View</th>

</tr>

<?php

include("config.php");



// connect to the mysql server

$link = mysql_connect($server, $db_user, $db_pass)

or die ("Could not connect to mysql because ".mysql_error());



// select the database

mysql_select_db($database)

or die ("Could not select database because ".mysql_error());





//first we need to decide how much to display per page 

$limit = 10; 



if(!isset($_GET['page'])){ 

  $page = 1; 

}else{ 

  $page = $_GET['page']; 

} 



//start and end records 

$start = ($page - 1) * $limit;



$search=mysql_query("SELECT hacksid, hackname, description, version FROM hacks WHERE `approved`='yes' AND `typeid`={$_GET['cat']}");



if(mysql_num_rows($search) > 0)

{

while($result=mysql_fetch_assoc($search))

{

echo "<tr valign='top'>\n";

$hacksid = $result['hacksid'];

$hackname = $result['hackname'];

$description = $result['description'];

$version = $result['version'];

echo "<td align=center>$hackname</td>\n";

echo "<td align=center>$description</td>\n";

echo "<td align=center>$version</td>\n";

echo "<td align=center><a href='hacks.php?hacksid=$hacksid'>View</a></td>\n";

echo "</tr>\n";

}

}

else

{

echo "<td align=center>there were no records found!</td>\n";

}

?>

</table>

</body>

</html>

the type table holds the categorys for hacks

Code:

  
typeid  name             link  
 1       Add-On's         cat.php?cat=1 
  2      Admin Tools      cat.php?cat=2 
  3      BBCode            cat.php?cat=3 
  4      Communication    cat.php?cat=4 
  5      Cosmetic/Styles    cat.php?cat=5 
  6      Syndication          cat.php?cat=6 
  7      Security              cat.php?cat=7 
  8      Profile                 cat.php?cat=8

Google Pagination i think is what you want. Some nice tutorials on there- i can't remember which one i used.

Use the LIMIT and ORDER BY functions of mySQL.

LIMIT works like so: LIMIT $start, $show

$start = first row to show
$show = number of rows to show

So if its LIMIT 5, 12
It will shows records 5 to 17.

PHP Code:


if(isset($_GET['page']))
    $page = $_GET['page'];
else
    $page = 1;
        
$start = ($page - 1) * 5;
                
$result = mysql_query("SELECT * FROM `articles` ORDER BY `posteddate` DESC LIMIT $start, 5 ");

That example will show 5 per page.

EDIT:

Oh, and heres the page numbering system I just wrote, should not be hard to adapt to whatever you want:

PHP Code:



                $total = mysql_num_rows(mysql_query("SELECT * FROM `articles`"));
                $max = ceil($total / 5);

#prev page
                if ($page > 1 && $total >= ($start - 1))
                    echo ' <a href="index.php?page=',($page-1),'">&lt;prev</a> ';    
                elseif ($max > 1)
                    echo '&lt;prev ';    
                
#page numbers
                if ($max > 1)
                    for($y = 1; $y <= $max; $y++)
                    {
                        if($page == $y) echo ' ',$page,' ';
                        else echo ' <a href="index.php?page=',$y,'">',$y,'</a> ';
                    }    
                
#next page                                        
                if ($total > (5 + $start))
                    echo ' <a href="index.php?page=',($page+1),'">next&gt;</a> ';
                elseif ($max > 1)
                    echo ' next&gt;';            

#no pages    
                if ($total == 0)
                    echo ' There are no articles to display. ';
