Pages of files from directory?

[rivka]

Okay, so I need to be able to read the contents of a directory (in this case, images), and then print out the results of that in alphabetical order with only 50 items per page, so that people can page through the results. Here's what I've got so far:

   $handle = opendir($direktori);

while ($file = readdir($handle)) 
{
        $filelist[] = $file;
    }

   asort($filelist);
   $temcount = 1;

while (list ($key, $file) = each ($filelist))
{
    if (ereg(".png|.gif|.jpg",$file))
    {
        if ($file == "." || $file == "..") {
            $a=1;
        } else {

            echo "<td width=\"80\"><img src=\"/images/$file\" alt=\"$file\"></td>";
        }

//print them out, 6 to a row
            if ($temcount == 6) {
                echo "</tr><tr>";
                $temcount -= 6;
            }
            $temcount ++;

    }
}

My problem is, I don't have a clue how to make it print out only 50 to a page. I suspect there's a for loop involved, but beyond that, I'm clueless. Any help or suggestions would be hugely appreciated...

Try this , it will work :

	$direktori = "../images";
	$handle = opendir($direktori);

while ($file = readdir($handle)) 
{
	if (ereg(".png|.gif|.jpg",$file))
	{
		if(!($file == "." || $file == "..") )
		{
			$filelist[] = $file;
		}
	}
}

asort($filelist);
$totalfiles = count($filelist);
$temcount = 0;
$startfrom=0;	
$limit = 20; 
if(!(!isset($page) || empty($page) || $page == "" || $page == 0))
{
	$startfrom = ($page - 1) * $limit;
	$endupto   = $page * $limit;
	if($endupto > $totalfiles )
		$endupto = $totalfiles;
}
if($totalfiles > $limit)
{
	if($totalfiles > $limit)
	{
		$page1=$totalfiles/ $limit;
		$page2=$totalfiles % $limit;

		if($page2 != 0)
			$totalfiles = intval($page1) + 1;
		else
			$totalfiles = (int)$page1;
	}

	$TPL_page_no .= "<table><tr><td>$std_font Page :</font></td>";
	for($i=1;$i <$totalfiles+1;$i++)
	{
		if($page == $i )
			$TPL_page_no .= "<td><font color=red face=\"Verdana\" size=\"2\">$i</font></td>";
		else
			$TPL_page_no .= "<td><font face=\"Verdana\" size=\"2\"><a  href=\"$PHP_SELF?page=$i\">$i</a></font></td>";
	}
	$TPL_page_no .= "</tr></table>";
}
$TPL_file_display = "<table border=1><tr><th colspan=6><font face=\"Verdana\" size=\"2\">Image : Directory</font></th></tr><tr>";
if($startfrom != 0 )
	$i=$startfrom+1;
else
	$i=$startfrom;

for($i=$startfrom;$i<$endupto;$i++)
{
	$file = $filelist[$i];
	//please check height and width of image to display , make same height and width for good look
	$TPL_file_display .= "<td width=\"80\"><img src=\"$direktori/$file\" alt=\"$file\"></td>";

	//print them out, 6 to a row
	if ($temcount == 5) 
	{
		$TPL_file_display .= "</tr><tr>";
		$temcount = 0;
	}
	else
		$temcount++;
}
$TPL_file_display .="</tr></table>";

print "$TPL_file_display";
print "<br>$TPL_page_no";

Thank you so much! That worked perfectly 🙂
