File Extensions

SP8600

With this code below could some one please tell me how i could add the file type to the end of the uploaded file when it has been uploaded. I can not just add the original name to the end to do it so i need another way of getting that file extension there.

$img1_rand = rand() % 99999999;
$img1_rand2 = rand() % 99999999;

if (is_uploaded_file($img1)) {

if ($img1_size>$max_size) { echo "The file is too big<br>\n"; exit; }

if (($img1_type=="image/gif") || ($img1_type=="image/pjpeg")) {

if (file_exists($path. $img1_rand . $img1_rand2)) { echo "The file already exists<br>\n"; exit; }

$res = copy($img1, $path . $img1_rand . $img1_rand2);
if (!$res) {
echo "&nbsp;&nbsp;upload failed!<br>\n"; exit; }
else
echo "";

} else { echo "&nbsp;&nbsp;Wrong file type<br>\n"; exit; }

}

Why can't you use this?

if (($img1_type=="image/gif") || ($img1_type=="image/pjpeg")) {

This also works too:

$filearray = explode('.', $file);
$filename = tempnam ('/wwwroot/files/', $filearray[0]).$filearray[1];

I am using the top one but i need a way to insert the files type to the end of the name in this line of code.

$res = copy($img1, $path . $img1_rand . $img1_rand2);

Aren't your img1_rand variables the new filename?

($img1_type=="image/gif") ? $ext = '.gif' : $ext = '.jpg';
$res = copy($img1, $path . $img1_rand . $img1_rand2 . $ext);

[MAN]move_uploaded_file[/MAN]

some hosts (one of mine at least) don't allow copy handling of temp upload files so I gotta use move_uploaded_file

Best way to test an uploaded file to make sure it's an image iw to use GD and get it's width (if you can't get size, it ain't an image basically)
