Sort Problem

[thechris]

I looked on the nulavatar forums already but couldn't find anything and I looked through the faq for it but couldn't find anything wrong there either.

What i'm getting is the warning
Warning: sort() expects parameter 1 to be array, null given in /Users/chrismorlang/Sites/admin/admin_nulavatar.php on line 674

here is the code
[code]
//
// [START] Add image
//
if($action == "addimage")
{
$location = '<a href="'.append_sid($file.'?action=images').'" class="nav">'.$lang['nulavatar_loc_images'].'</a> -> <a href="'.append_sid($file.'?action=addimage').'" class="nav">'.$lang['nulavatar_loc_addimage'].'</a>';
//

//
$dir = @opendir($phpbb_root_path . $sprites_path);

$firstimage = '';

while($file = @readdir($dir))
{
if( !@is_dir(phpbb_realpath($phpbb_root_path . $sprites_path . '/' . $file)) )
{
$img_size = @getimagesize($phpbb_root_path . $sprites_path . '/' . $file);

if( ($img_size[0] == $img_width) && ($img_size[1] == $img_height) )
{
$sprite_images[] = $file;
}
}
}

@closedir($dir);

sort($sprite_images); //LINE GIVING ME THE PROBLEM
$i_list = "";

for( $i = 0; $i < count($sprite_images); $i++ )
{
if ($firstimage == '')
{ $firstimage = $sprite_images[$i]; }
$i_list .= '<option value="' . $sprite_images[$i] . '">' . $sprite_images[$i] . '</option>';

It means there is no value to that array. before
while($file = @readdir($dir))

add $sprite_images = array();
And take off all the @s so you can get the errors from readdir and other functions. There's your problem.
