Form Post Issues

[Philip D Heady]

I have a webpage that uploads a photo picture file to server, but goes
through some error checking before it redirects to the next page. Since I do
not have PHP compiled with mime type support I have checking last 3
characters of filename. Here are my problems:

1) When I set form type to ENCTYPE="multip art/form-data" i can check the
file size correctly and works fine, but then filename and extension are in
some weird format which is binary I believe.

form = 1
Photo: /tmp/phpnDF01W
image_x = 89
image_y = 16
Ext: 01w < this is wrong, should be gif/jpg/etc...
Size: 34326
File: /tmp/phpnDF01W < this is wrong

2) When I omit the above form type and use default, file size function fails
but the extension and filename work correctly. I believe this is because it
is sent in ascii/plain text mode.

Warning: filesize(): Stat failed for C:\\WINDOWS\\De sktop\\sci.psd
(errno=2 - No such file or directory) in
/home/fcl/public_html/free/index3.php on line 30

form = 1
photo = C:\\WINDOWS\\De sktop\\sci.psd
image_x = 66
image_y = 12
Ext: psd
Size: ??????
File = C:\\WINDOWS\\De sktop\\sci.psd

3) I'm also trying to get the file to the server and it's not uploading it.
It's creating the directories but not moving the file up there for me!!


4) Here is code. What is going on? Can I kill 3 birds with one stone here???
I'd rather not recompile PHP. Must I convert $ext from binary to plain
text??

while(list($key , $value) = each($HTTP_GET_ VARS)) {

echo "$key = $value<br>";
}


if ($form) {

if ($photo) {

$ext = strtolower(subs tr($photo, -3));

function fsize($photo) {
return filesize($photo );
}

$size = fsize($photo);

if ($size > 100000) {

$focus = "photo";
$msg = "Your file size exceeds the maximum allowed
upload. Please re-submit or skip this step.";

} elseif (!preg_match("/(gif|peg|jpg|bm p|png)$/",
$ext)) {

$focus = "photo";
$msg = "Invalid file type. Please submit a gif, jpeg,
bmp, or png photo.";

} else {

if ($ltype == "1") { $type = "hotel"; }<-- this all works fine, etc
if ($ltype == "2") { $type = "inn"; }
if ($ltype == "3") { $type = "bandb"; }
if ($ltype == "4") { $type = "resort"; }

$imgdir = "$DOCUMENT_ ROOT/lodging/$type"; <-- this all works fine,etc
if (!file_exists($ imgdir)) { mkdir($imgdir, 0755); }
$imgdir.= "/$aid";
if (!file_exists($ imgdir)) { mkdir($imgdir, 0755); }

move_uploaded_f ile($photo, "$imgdir/photo1.jpg"); <---this is not
working!!

loc("index4.php ?sid=$sid&aid=$ aid"); <-- works fine

}}


<form name="form1" method="post"
action="<?=$SCR IPT_NAME?>?sid= <?=$sid?>&aid=< ?=$aid?>&ltype= <?=$ltype?>"
ENCTYPE="multip art/form data">
<input type="hidden" name="form" value="1">

No, it's not wrong. It's just the unique temporary name PHP gives to
the temporary copy of the file. The file name attribute is
independently available to you, just not there. Try this:

<?php
if (!isset($infile )) {
echo '
<form action="'.$PHP_ SELF.'" ENCTYPE="multip art/form-data"
method=post>
<input type=file name=infile><br >
<input type=submit>
</form>
';
} else {
echo '
File Name:'.$infile_ name.' is '.$infile_size. ' bytes in size.
';
}
?>

Note the name of the file ($infile) in the form and the use of the
system-generated variables $infile_name and $infile_size.

Not that I'd ever use that approach. For starters, I'd want to rename
the file to a unique value, something like a database record number.
[color=blue]
> } elseif (!preg_match("/(gif|peg|jpg|bm p|png)$/",$ext)) {[/color]

And I'd never trust end-user input to be that correct. Mac users among
others aren't likely to bother with file name extensions at all.

Use the in-built image functions to get the definitive image type.

$imagestats=get ImageSize($infi le);

if ($imagestats[2]=1) {
copy ($infile, "images/user1.gif");
} elseif ($imagestats[2]=2) {
copy ($infile, "images/user1.jpg");
} elseif ($imagestats[2]=3) {
copy ($infile, "images/user1.png");
} elseif ($imagestats[2]=6) {
copy ($infile, "images/user1.bmp");
} elseif ($imagestats[2]=7) {
copy ($infile, "images/user1.tiff");
} elseif ($imagestats[2]=9) {
copy ($infile, "images/user1.tiff");
} else {
echo '
Sorry user1, supplied file is not a supported image type!
';
}

Re: Form Post Issues

Thank you. This works like a charm!

$imagestats=get ImageSize($phot o);

$imgdir = "$DOCUMENT_ ROOT/lodging/$type";
if (!file_exists($ imgdir)) { mkdir($imgdir, 0755); }
$imgdir.= "/$aid";
if (!file_exists($ imgdir)) { mkdir($imgdir, 0755); }

if ($photo_size > 100000) {

$focus = "photo";
$msg = "Your file size exceeds the maximum allowed upload of
100k.<br>Please re-submit or skip this step.";

} elseif (!preg_match("/(1|2|3|6|7|8)$/", $imagestats[2])) {

$focus = "photo";
$msg = "Invalid file type. Please submit a gif, jpeg, bmp, png, or tiff
photo. Or skip this step.";

} else { etc..
