Need help, creating multiple pages.

I have a news system, that gets 5 rows of data.

I need to make it where it has pages, and gets 5 rows of data on each page, if available.

Heres some of my code:

Code:

<?php
$query = 'SELECT * FROM gdl_news ORDER BY date_entered DESC limit 0,5';
if ($r = mysql_query ($query)) { 
	while($row = mysql_fetch_array ($r)) {
		
		print "<p><b>{$row['subject']}</b> - {$row['date_entered']}<br />
	 {$row['news_entry']}<br /></p><hr />\n";
	 }
   }else{
   die('Could not retrieve data because:<b>' . mysql_error() . '</b>.');
   }
   
?>

In the LIMIT 0,5 , assign a var to 0 somrhting like $temp_var=0.

Now, when you want to change page pass the new $temp_var
example <a href="mypage.php?p=5">Next</a>
So in the new page the $temp_var would be 5 and your LIMIT 0,5
would become LIMIT 5,5

Finnaly you would get something like :

<?
if ($p!="")
{
$temp_var = $p;
}
else
{
$temp_var=0;
}

// execute your query here

?>

Suggestion: make yout LIMI dynamic -> LIMIT $var,5
above your query write something like:

PHP Code:


		
			
<?
if ($p!="")
{
$var = $p;
}
else
{
$var=0;
}
?>

Now in your query write LIMIT $var,5 instead of 0,5

and your link would be something like:
mypage.php?p=5

In this way, when you click on the link the $var becomes 5 and the LIMIT 0,5
becomes LIMIT5,5

Ideally you need to read some tutorials on pagination
