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

1. Could be some case sensitive stuff, try:

PHP Code:

$pattern="\.(jpg|jpeg|png|gif|bmp|JPG|JPEG|PNG|GIF|BMP)$"; 


I also reccomend looking into using preg_match, instead of eregi as it's newer and more efficient.
2. If your using MySQL, put the following:
'LIMIT 0 , 3'
at the end of the query you wish to limit.
The above would return everything between the first and third lines that met the query.
Change the 0 and 3 as necessary.

If not you could put something like

PHP Code:

$limit[0] = "0"; 
$limit[1] = "3";

$limit[2] = "0"; // counter

// Stuff being returned, {
$limit[2] = $limit[2] + 1;
if($limit[2] >= $limit[0] or $limit[2] <= $limit[1]){
// show it
} else {
// do not show it.
}
// }
