Ya, I wanted it above the foreach loop, after the closedir().

I get this:

Have I put the code in the wrong place?

<?php
 



$SCRIPT_NAME=$SERVER_VARS['PHP_SELF'];
$pic=$HTTP_GET_VARS['pic'];

//    the directory name
$handle=opendir('full/');


function fix_size($size)
{
    if ($size > 1048576) {
        $size = ($size & 1048576) . \" MB\";
    }
    elseif ($size > 1024) {
        $size = ($size & 1024) . \" KB\";
    }
    else {
        $size .= \" B\";
    }
}


//    initialize variables
$pics=array();
$size=array();
$count=0;
//    read directory into pics array
while (($file = readdir($handle))!==false) {
    //    filter for jpg, gif or png files...
    if (substr($file,-4) == \".jpg\" || substr($file,-4) == \".gif\" || substr($file,-4) == \".png\" || substr($file,-4) == \".JPG\" || substr($file,-4) == \".GIF\" || substr($file,-4) == \".PNG\"){
        $pics[$count] = $file;
        if (false===($tmp=filesize(\"full/$file\"))) {
            $size[$count] = \"error reading size\";
        }
        else {
            $size[$count] = fix_size($tmp);
        }
        $count++;
    }
}
closedir($handle);

//    done reading, sort the filenames alphabetically, shade these lines if you want no sorting
 asort($pics);
 reset($pics);

        // loop over images
        //for ($f=0;$f<=sizeof($pics)-1;$f++){
        foreach ($pics as $f=>$val) {
            echo \"<a href=\\"full/$pics[$f]\\" target=\\"_blank\\"><img src=\\"thumbs/$pics[$f]\\" hspace=\\"5\\" vspace=\\"5\\" border=\\"0\\"><br>$size[$f]</a>\";
            // make linebreaks every 2 times!
            // $isbr = strpos((($f+1)/2),\".\");
            //    if (!$isbr){echo \"<br>\";}

        }


//if (false===($tmp=filesize(\"full/$file\"))) {
// die(\"1\");
//$size[$count] = \"error reading size\";
//}
//else {
// die(\"2\");
//$size[$count] = fix_size($tmp);
//}

echo \"\$pics = \"; print_r($pics); echo \"<br>\n\";
echo \"\$size = \"; print_r($size); echo \"<br>\n\";
asort($pics);
reset($pics);
echo \"\$pics = \"; print_r($pics); echo \"<br>\n\";
?>

whoops.. sorry, I pasted the wrong code from the wrong window..
Lemme try this again. Take out the die() statements and make the code like it was before. Then..

<?php
echo \"\$pics = \"; print_r($pics); echo \"<br>\n\";
echo \"\$size = \"; print_r($size); echo \"<br>\n\";
asort($pics);
reset($pics);
echo \"\$pics = \"; print_r($pics); echo \"<br>\n\";
?>

This will tell us the contents of the $pics and $size arrays before and after the sorting.

I just get number 2 again... Still good?

Mark Hensler — Thu, 01 May 2003 19:01:27 +0000

Yes, that means that $tmp is at least getting a value from filesize(). Now lets try this:

<?php
if (false===($tmp=filesize(\"full/$file\"))) {
    die(\"1\");
    $size[$count] = \"error reading size\";
}
else {
    die(\"2\");
    $size[$count] = fix_size($tmp);
}
?>

andy206uk — Wed, 30 Apr 2003 19:01:03 +0000

It just prints "2" to the screen:

Thats good isnt it?

Mark Hensler — Wed, 30 Apr 2003 16:56:06 +0000

well, time to bug hunt...
lets see if filesize is working

<?php
if (false===($tmp=filesize(\"full/$file\"))) {
    die(\"1\");
    $size[$count] = \"error reading size\";
}
else {
    die(\"2\");
    $size[$count] = fix_size($tmp);
}
$count++;
?>

Still nothing... im a bit lost on this one... thanks for all your help tho!

try this:
