Form problems...

[Anon]

How come... I get an error if I use form tag like this:

<form method="post" enctype="multipart/form-data" action="do_form.php3">

but when I do it without enctype="multipart/form-data" I don't.

The error prints out because of these lines here:

if ($img) {
$size = GetImageSize("$img");
checksize($size[0], "450", "width");
checksize($size[1], "450", "height");
} else {
echo "<img src=\"alert.red.gif\">\n";
}

and the error is:

Warning: Unable to open none in c:\apache\htdocs\horse-2\do_form.php3 on line 224

Any solutions?
Thanks, Arni

If you don't have that in there, the file input box is just treated like a normal text box. The box is empty, so if ($img) fails. With that line, though, it's actually treated as a file box. If it's empty, then $img=="none". Change your if statement.

if ($img != "none")
{ //image uploaded...do something; }
