    I have a site that has alot of pages, but it navigation is becoming too big. At the more its like " 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32". Now I want it to be like << 1 2 [3] 4 5 >> and lets say you was on page 20 it would be << 16 17 [20] 21 22 >>. I have a basic pagin system at the moment how would i add this? The site is www.ps3.sc

    Something like the following should work

    $current_page = $_GET['p'];

//Page display width - number of pages on each side of the current
$page_width = 2;

//Echo code for previous page

echo "<a href='http://www.ps3.sc/?p=" . ($current_page - 1) . "'> < </a>";

$x = $current_page - $page_width;

while ($x <= ($current_page + $page_width)) {
	
	if ($x == $current_page) {
		echo " [" . $x "] ";
	} else {
		echo " <a href='http://www.ps3.sc/?p=" . $x . "'>" . $x . "</a> ";
	}
	
	$x++;

}


//Echo code for next page

echo "<a href='http://www.ps3.sc/?p=" . ($current_page + 1) . "'> > </a>";

    Streety, Thanks I've got it working. But its like this << Prev -3 -2 [ -1 ] 0 1 Next >>, see the minus numbers? I have tried several ways to remove them when the page is one or below but no luck, any help?

    No problem, try this . . .

    <?php

if(isset($_GET['p'])) {
	$current_page = $_GET['p'];
}
else {
	$current_page = 1;
}


//Page display width - number of pages on each side of the current
$page_width = 2;

//Maximum and minimum page numbers
$min_page = 1;
$max_page = 10;

//Echo code for previous page
if (($current_page - 1) >= $min_page) {
	echo "<a href='http://www.ps3.sc/?p=" . ($current_page - 1) . "'> < </a>";
}
	


$x = $current_page - $page_width;

while ($x <= ($current_page + $page_width)) {

	if ($x == $current_page) {
		echo " [" . $x . "] ";
	} elseif (($x < $min_page) || ($x > $max_page)) {
		//Do nothing
	}
	else {
		echo " <a href='http://www.ps3.sc/?p=" . $x . "'>" . $x . "</a> ";
	}

	$x++;
	
}

//Echo code for next page
if (($current_page + 1) <= $max_page) {
	echo "<a href='http://www.ps3.sc/?p=" . ($current_page + 1) . "'> > </a>"; 
}

?>
    PHP:
    You would get the same problem at high numbers (going to pages you haven't created yet) but this script should fix that side of things as well.

    I don't know how you store your pages so I've just put a value (10) in for the moment. You could either manually update it each time you add a page or set it dynamically by counting the rows in your database table or files in your directory depending on what you use.
