<?php
$page = $_GET['page'];
$rpp = 4;
$c = 0;

if($handle) {

   while(false !== ($file = readdir($handle))) {

   if(preg_match("/\w+(.gif)/",$file)) {
       $c++;
       if ($c > (($page * $rpp) + $rpp)) break;

good morning mister russel!

 

here's what i got so far...the problem is when i declare value "3" in the $rpp variable or row per  page...it will display  4 images instead of 3...and i also noticed that the last image in every page is still present on the second page(and it was placed first)...i'm sure i got some mistake with my code but i just can't figure it out....would you please help... im getting frustrated with this...T_T

 

<?php

	$page = $_GET['page'];
	$rpp = 3;
	$c = 0;
	$handle = opendir('comments/');
	$d = opendir("comments/");
	$count = 0;

	while(($f = readdir($d)) !== false)
	if(ereg('.gif$', $f))
	++$count;
	closedir($d);

	print "$count";		

	$numOfPages = ceil( $count / $rpp );

	if($handle) {

		while(false !== ($file = readdir($handle))) {

			if(preg_match("/\w+(.gif)/",$file)) {

			   $c++;
			   if ($c > (($page * $rpp) + $rpp)) break;
			   if ($c >= ($page * $rpp)) {
					  echo "<div class='update_pics_frame'>";
					  echo "<div class='update_pics'>";
					 	 echo "<a href='comments/$file'><img src='comments/$file' width='200'border='0'></a>";
					  echo "</div>";
					  echo "</div>";
					  
			   }
			}
		}

		closedir($handle);
	}



	for ($i = 1; $i <= $numOfPages; $i++) {
  		
		echo "<a href='view_pix.php?page=$i'>";
			echo " ".$i." ";
		echo "</a>";

	}

?>

<?php
$page = $_GET['page'];
$rpp = 4;
$dirArr = scandir('comments/');
function rem_invalid($arr) {
	foreach ($arr as $k => $v) {
		if (stristr($v,'.gif') === false) unset($arr[$k]);
	}
}
$dirArr = preg_grep("/^.*\.gif$/i",$dirArr);
if ($c = count($dirArr)) {
	$dirArr = array_combine(range(0,count($dirArr) - 1),$dirArr);
	$numOfPages = ceil($c / $rpp);
	for ($i = (($page - 1) * $rpp); $i < min($c,($page * $rpp)); $i++) {
		echo $dirArr[$i]."<br/>";
	}
}
echo "<br /><br />";
print_r(range(1,$numOfPages));
?>

yeah that'd be pretty difficult to toy with

 

what you should do, is avoid this whole loop thing, throw all the upload files into a database, with the filename and path to the file in the db, and an auto increment id that way you can order by descending an then get the filenames from there.
