Simple Page Pagination?

[sitedesigner]

I want to add pagination to this.

<?

$dh = opendir( $dir );                                           
      while( $filename = readdir( $dh ) ) {                             
           $filepath = $dir.$filename;                                  
           if( is_file( $filepath ) and ereg( "\.jpg$", $filename )  || ereg( "\.gif$", $filename ) || ereg( "\.png$", $filename ) ) { 
                $gallery[] = $filepath;
           }
                      
function DateCmp($a, $b) {
      if($a[1]==$b[1]) return 0;
      else return ($a[1] < $b[1]) ? -1 : 1;
}

function SortByDate(&$Files) {
    usort($Files, 'DateCmp');
}

SortByDate(array_reverse($gallery));    
      
foreach( $gallery as $image ) {
           echo "<li><a href='$image'><img src='$image' alt='$cat$count' /></a></li>";
        }

?>

Thanks!

Okay, what have you tried?

[sitedesigner]

I haven't tried anything yet, because I don't even have a clue how to do it

How about something like this:

$gallery = array();
$dir = $_SERVER['DOCUMENT_ROOT']."/test/images/";
$dh = opendir( $dir );                                           
while( $filename = readdir( $dh ) ) {                             
	$filepath = $dir.$filename;                                  
	if( is_file( $filepath ) and (ereg( "\.jpg$", $filename )  || ereg( "\.gif$", $filename ) || ereg( "\.png$", $filename )) ) { 
		$gallery[] = $filepath;
	}
}
 
function DateCmp($a, $b) {
	if($a[1]==$b[1]) return 0;
	else return ($a[1] < $b[1]) ? -1 : 1;
}
function SortByDate(&$Files) {
	usort($Files, 'DateCmp');
}
SortByDate(array_reverse($gallery)); 
 
$perpage = 5;
$total = count($gallery);
$start = isset($_GET['start']) ? $_GET['start'] : 0;
 
for($i = $start; $i < $current+$perpage; $i++){   
	#echo "<li><a href=\"{$gallery[$i]}\"><img src=\"{$gallery[$i]}\" alt=\"$cat$count\" /></a></li>";
	echo $image."<br>";
}
echo "<br><br>";

I assume you can manage the paging link at the bottom.

[sitedesigner]

is the paging link within the for loop? or after the for loop?

Think about it.

Do you want the paging link displayed multiple times (inside the loop) or just once (outside the loop)??

Ok, so here's the pagination that i came up with. Couple things

Say the array as 14 images in it.
the script still goes to the 4th page, even though there arent any images on that page. any help as to why?

Thanks!

<?php

$numperpage = 5; // number of results per page

if (isset($_GET['page'])) {
  $page = intval($_GET['page']) - 1;
} else {
  $page = 0;
}

            $dir = 'icon/animals/';
            
            <ul>
                  <?
    if($nodir==1) { include 'favourites.php'; } else {
      $dh = opendir( $dir );                                           
      while( $filename = readdir( $dh ) ) {                             
           $filepath = $dir.$filename;                                  
           if( is_file( $filepath ) and ereg( "\.jpg$", $filename )  || ereg( "\.gif$", $filename ) || ereg( "\.png$", $filename ) ) { 
                $gallery[] = $filepath;
           }
      }
      
//-find the date of each file
function DateCmp($a, $b) {
      if($a[1]==$b[1]) return 0;
      else return ($a[1] < $b[1]) ? -1 : 1;
    }
// sort each array
function SortByDate(&$Files) {
    usort($Files, 'DateCmp');
    }
// reverse the array to get in correct order
SortByDate(array_reverse($gallery));    
    

  

      for ($i = ($page * $numperpage); ($i < (($page * $numperpage) + $numperpage) && $i < count($gallery)); $i++         ) {
           $image = $gallery[$i];
           echo "<li><a href='$image'><img src='$image' alt='$cat$count' /></a></li>";
    }
$back = $page;
$next = $page + 2;
$display = $page + 1;
echo "<p>page $display - (Gallery: " . count($gallery) . " images) - ";



if ( $page == 0 && ($numperpage < count($gallery)) )
echo "<a href=?page=$next>next »</a>";
else if ( count($gallery) <= ($page * $numperpage) )
echo "<a href=?page=$back>« back</a>";
else if ( count($gallery)%($page * $numperpage) > 0 )
echo "<a href=?page=$back>« back</a> | <a href=?page=$next>next »</a>";
else 
echo "Page Error";
