directory based image gallery assistence

[Stickybomb]

i am try to create a simple script that will read a directory, get the images in it and write them to the page. It would also seperate them in to multiple pages. This is what i have so far

 

gal.php

<?php
$limit=5;

function returnimages($dirname) {
   $pattern="\.(jpg|jpeg|png|gif|bmp)$";
   $curimage=0;
   if($handle = opendir($dirname)) {
       while(false !== ($file = readdir($handle))){
               if(eregi($pattern, $file)){
                 $galleryarray[$curimage]=$file;
                 $curimage++;
               }
       }

       closedir($handle);
   }
   return($galleryarray);
}
?>

 

page to display the images

<?php
include('gal.php');
if(isset($_GET['year'])){$year=$_GET['year'];}else{$year=2001;}
$image = array();
$image = returnimages('IFAIphotos/'.$year);
$limit = 5;
$images = count($image);
$totalrows = ceil($images/2);
$numofpages = ceil($totalrows / $limit);
if(isset($_GET['page'])){$page=$_GET['page'];}else{$page=1;}
$limitvalue = ($page-1) * $limit;
?>

<p align="center"><img src="IFAIphotos/<?=$year;?>/<?=$year;?>_logo.jpg" alt="IFAI <?=$year;?>" /></p>
<?php
for($i=1;$i==$images;$i++){
echo '<p align="center"><img src="IFAIphotos/'.$year.'/'.$image[$i].'" alt="1" width="150" hspace="5" />';
$i++;
echo '<p align="center"><img src="IFAIphotos/'.$year.'/'.$image[$i].'" alt="1" width="150" hspace="5" /></p>';
}
?>
<p align="center"><span class="pagenav">
<?php
if($numofpages!=1){
if($page!=1){
	$pageprev = ($page-1);
	echo '<a href="preevent.php?year='.$year.'&page='.$pageprev.'">PREV</a> ';
}															
for($i = 1; $i <= $numofpages; $i++){
	if($i == $page){
		echo($i." ");
	}else{
		echo('<a href="preevent.php?year='.$year.'&page='.$i.'">'.$i.'</a> '); 
	 }        
}
if(($totalrows - ($limit * $page)) > 0){ 
	$pagenext = ($page+1);
	echo('<a href="preevent.php?year='.$year.'&page='.$pagenext.'">NEXT</a>');
}else{
	echo(""); 
        }
}
?>

 

basically the problems i am having are

1. i can not seem to get the filename for each image. The for loop to echo the images displays nothing

2. I know how to do it using a database driven system but am stumped on how to limit the rows of images per page for it to be pageinated.

 

can someone please lend some assistence on this

 

thanks
