Billede upload med scalering af billede
Hej igen.Jeg er stødt på endnu et problem. jeg har en hjemmeside hvor en maler skal kunne uploade sine billeder. dette virker perfekt, dog vil jeg gerne have dem scaleret ned i pixel. hvordan gør jeg nu det..
Koden til visning af billeder ser således ud:
<html>

function get_files_from_dir($dirname)
{
$dirhandle = opendir($dirname);
while($file = readdir($dirhandle))
{
if ($file != "." && $file != "..")
{
if (is_file($dirname."/".$file))
{
$GLOBALS['files'][] = $dirname."/".$file;
}
else
{
get_files_from_dir($dirname."/".$file);
}
}
}
}
get_files_from_dir("upload/acryl");
get_files_from_dir("upload/tegning");
get_files_from_dir("upload/tryk");
get_files_from_dir("upload/akvarel");
foreach($GLOBALS['files'] as $file)
{
echo "<a href='$file' target='_blank'>" . "<br /><img src='$file'/></a><br />";
}
?>
</div>
</div>
</body>

Koden til upload af billeder ser således ud:
