[SOLVED] Pagination - followed tutorial but links dont work!!

Hi guys you've probably heard this a hundred times but I have been following the pagination tutorial by TheReverend at http://www.phpfreaks.com/tutorials/43/5.php?topic_id=6691&hl=6691#6691 and it doesnt quite seem to work properly. I have tried to access the discussion links as it looked like people have had the same problem as me, but they arent working.

I will post my code below showing how I have implemented the code:

<?php 


// File: message.php


define('IN_FORUM', true);
//include_once "sqlconnect.php";
include_once "includes/functions.php";

include "includes/header.php";

$genreid=$_GET['genreid'];
$id=$_GET['id'];
$title=$_GET['title'];

echo "<link rel='stylesheet' href='style.css' type='text/css'>";

echo "<a href='index.php'>Home</a>";

if(isset($_SESSION['session_loggedIn']) && $_SESSION['session_loggedIn'] == 1)
 {
	echo " - <a href='reply.php?id=$id&genreid=$genreid&title=$title'>Reply</a><br />";
 }



$limit = 5;
$query_count = "select count(*) from forum_posts where postid='$id' or parentid='$id'";
$result_count = mysql_query($query_count);  
$totalrows = mysql_num_rows($result_count);  
if(empty($page)){    // Checks if the $page variable is empty (not set)
        $page = 1;      // If it is empty, we're on page 1
	} 
$limitvalue = $page * $limit - ($limit); 
    // Ex: (2 * 25) - 25 = 25 <- data starts at 25 
$getposts = "select * from forum_posts where postid='$id' or parentid='$id' order by realtime asc limit $limitvalue, $limit";
$getposts2=mysql_query($getposts) or die("Error: " . mysql_error());
if(mysql_num_rows($getposts2) == 0){
        echo("Nothing to Display!");
    } 

$bgcolor = "#E0E0E0";

echo "<table class='maintable'>";

echo "<tr class='headline'><td width=20%>Author</td><td width=80%>Post</td></tr>";

while($row=mysql_fetch_array($getposts2)) {

if($bgcolor == "#E0E0E0"){
            $bgcolor = "#B0BFEF";
        }else{
            $bgcolor = "#E0E0E0";
        }

echo "<tr bgcolor=".$bgcolor." class='mainrow'><td valign='top'>$row[author]</td><td valign='top'>Posted on $row[showtime]<br><hr>";

$message=strip_tags($row['post']);
$message=bb($message);
$message=nl2br($message);

echo "$message<hr>";

if(isset($_SESSION['session_loggedIn']) && $_SESSION['session_loggedIn'] == 1  && $_SESSION['session_userName'] ==
 $row[author])
 {	 
  echo "<a href='edit.php?id=$row[postid]&title=$row[title]'>Edit Post</a>";
 }

echo "</td></tr>";
}

echo "</table>";

if($page != 1){ 
        $pageprev = $page--;
        // Fancy way of subtracting 1 from $page
        
        echo("<a href=\"$PHP_SELF&page=$pageprev\">PREV" .$limit."</a> ");  
        /* Tip: It is a good idea NOT to use $PHP_SELF in this link. It may work, 
but to be 99.9% sure that it will, be sure to use the actual name of the file 
this script will be running on. Also, the   adds a space to the end of 
PREV, and gives some room between the numbers. */
    }else
        echo("PREV".$limit." "); 
        // If we're on page 1, PREV is not a link 

$numofpages = $totalrows / $limit; 
    /* We divide our total amount of rows (for example 102) by the limit (25). This 

will yield 4.08, which we can round down to 4. In the next few lines, we'll 
create 4 pages, and then check to see if we have extra rows remaining for a 5th 
page. */
    
    for($i = 1; $i <= $numofpages; $i++){
    /* This for loop will add 1 to $i at the end of each pass until $i is greater 
than $numofpages (4.08). */
    
        if($i == $page){
            echo($i." ");
        }else{
            echo("<a href=\"$PHP_SELF&page=$i\">$i</a> "); 
        }
        
        /* This if statement will not make the current page number available in 
link form. It will, however, make all other pages available in link form. */
    }   // This ends the for loop 

if(($totalrows % $limit) != 0){
    /* The above statement is the key to knowing if there are remainders, and it's 
all because of the %. In PHP, C++, and other languages, the % is known as a 
Modulus. It returns the remainder after dividing two numbers. If there is no 
remainder, it returns zero. In our example, it will return 0.8 */
     
        if($i == $page){
            echo($i." ");
        }else{
            echo("<a href=\"$PHP_SELF&page=$i\">$i</a> ");
        }
        /* This is the exact statement that turns pages into link form that is used 

above */ 
    }   // Ends the if statement 

if(($totalrows - ($limit * $page)) > 0){
    /* This statement checks to see if there are more rows remaining, meaning there 
are pages in front of the current one. */
    
        $pagenext   = $page++;
        // Fancy way of adding 1 to page
         
        echo("<a href=\"$PHP_SELF?page=$pagenext\">NEXT".$limit."</a>");
        /* Since there are pages remaining, this outputs NEXT in link form. */ 
    }else{
        echo("NEXT".$limit); 
        /* If we're on the last page possible, NEXT will NOT be displayed in link 
form. */
    } 


include "includes/footer.php";

?>

At the moment the limit works fine but the PREV and NEXT links dont work and it doesnt display the page numbers either.

Any help would be greatly appreciated,

Cheers!

Look at my reply to this post

http://www.phpfreaks.com/forums/index.php/topic,172220.msg763400.html#msg763400

Here is another working example you can look at

<?php

$limit          = 10;
$query_count    = "SELECT count(*) FROM table";
$result_count   = mysql_query($query_count) or die("Error: " . mysql_error());
$totalrows      = mysql_result($result_count, 0, 0);
$numofpages     = ceil($totalrows/$limit);

if (isset($_GET['page'])) $page = $_GET['page'];
else $page = 1;

$offset = ($page - 1) * $limit;
$query  = "SELECT * FROM table LIMIT $offset, $limit";

echo  $query .'<br>';
$result = mysql_query($query) or die("Error: " . mysql_error());

//Exit if no records to display
if (mysql_num_rows($result) == 0) {
    exit("Nothing to Display!");
}

while ($row = mysql_fetch_array($result)) {
    echo $row['col']."</br>";
}


//Enable the Prev link if not first page
if ($page > 1) {
    echo("<a href=\"index.php?page=".($page-1)."\">PREV</a> ");
} else {
    echo("PREV ");
}

//Create links for each page in report
for ($i=1; $i<=$numofpages; $i++) {
    if ($i == $page) {
        echo "$i ";
    } else {
        echo "<a href=\"index.php?page=$i\">$i</a> ";
    }
}

//Enable the Next link if not last page
if ($page < $numofpages) {
    echo("<a href=\"index.php?page=".($page+1)."\">NEXT</a>");
} else {
    echo("NEXT");
} 

?>

can someone from the phpfreaks team please fix the tutorial so that

this problem does not come up again?

Thanks for the help guys, got it working now. And yes would be good if someone could fix the tutorial!
