Thumbnail creation ... pls help reward if you can :)

robsgaming

I've been messing with this all afternoon and it is not working. What I'm trying to do is upload an image, then have PHP automatically make a copy of the image, resize it to 160 x 120, and save the copy with a dif file name. Uploading the image works fine.... the thumbnail part is hard.

heres the code that i have just to upload the image --- i took out the code that was supposed to resize the image... what would I do and how would i do it?

<html>

<? $gametitle = stripslashes($gametitle); ?>
<form action="<? $PHP_SELF ?>" method=post enctype="multipart/form-data">
Upload:<input type=hidden name=MAX_FILE_SIZE value=10000000000>
<input type=file name="userfile"><br>
<input type="hidden" name="gameid" value="<? echo $gameid ?>">
<input type="hidden" name="gametitle" value="<? echo $gametitle ?>">
<input type="hidden" name="system" value="<? echo $system ?>">
<input type=submit value="Upload!" name=submit><br>
</form>

echo "<B>Add $gametitle Screenshots</B><P>";
if($submit) {
if(!empty($userfile)) {

$date = date("gismdY");
$rand = rand(1,20);
$complete = $date.$rand;
$type = split(".",$userfile_name,2);
$type2 = $type["1"];
copy($userfile, "/home/virtual/site10/fst/var/www/html/imgupload/$complete.$type2");
unlink($userfile);

* I Had the code that would make a copy of the uploaded image to a smaller copy and rename it , obviously didn't work*

$db = mysql_connect("localhost", "xxx", "xxx");
mysql_select_db("robsgaming",$db);
mysql_query("INSERT INTO imgupload (filename,gameid,gametitle,system) VALUES ('$complete.$type2','$gameid','$gametitle','$system')");

echo("$complete.$type2 file uploaded");
}
}

?>
</html>

Please reply back. If anybody can help me get this working I'll pay you $5 or so on pay pal...

That will make and store thumbnails (in PNG format) of uploaded GIF(if supported)/PNG/JPEG images.

It requires GD2 support as the GD1 functions I was using just produced black images - I've left those functions in (but commented out) in case you want to try them. (the problem might just be with my GD build).

It was written for PHP4.1.0+ but should be ok on older versions.

I tried the script and I keep getting "unsupported image type"

what could be causing this?

dannys

What image types does your GD installation support? You can get that info by making a file containing:

<?php phpinfo(); ?>

At a guess, I'd say you're trying to upload a GIF and your GD installation has no GIF support.

robsgaming

Also, i noticed something when i view the source of just the form.

For some reason, the values of gameid, system, and the others are not defined.... however, they are present in the URL at the top.... what is causing this? If you are still willing to help I will pay you for your trouble.

dannys

Most likely caused by register_globals being turned off in the latest versions of PHP.

You can't just use $systemid now - try $GET['systemid'] or $POST['systemid'] instead.

robsgaming

GD Support enabled
GD Version 1.6.2 or higher
FreeType Support enabled
FreeType Linkage with freetype
JPG Support enabled
PNG Support enabled
WBMP Support enabled

dannys

Yep, no GIF support (and an old version of GD) you won't be able to make thumbnails out of uploaded GIFs.

I don't suppose imagemagik is installed on your system? If it is, you could probably use that (you can call it through PHP). You'll have to ask you sysadmin if it's installed.

robsgaming

Hmm, even when i post a jpeg image it still says unsported file type.... dunno why

dannys

Was the extension .jpg?

robsgaming

yes i tried multiple jpeg files with .jpg as extension as well as created one myself...
still getting image error

dannys

Hmm, that certainly shouldn't be happening.

Find the section of code where it says "list(,$type)..." and add the following line directly underneath:

echo "Got file of type: $type";

You might also want to change a line.

switch($type)

switch(strtolower($type))

robsgaming

ok i echoed it out and it said "

Got file of type: ork.jpg

" but the name of the file is work.jpg

its showing ork.jpg

also tried with a png file i made, same problem...

dannys

There's something seriously wrong - it should have said:

"Got file of type: jpg"

Sure you didn't make any mistakes during the copy/paste of my code?

What version of PHP are you running btw?

robsgaming

positively sure

version:

PHP Version 4.2.2

dannys

vBulletin screwed my code (I forgot you've got to double every \ in the PHP code).

Check the line with list(,type) again and you should see that the split() command is slightly different.

Damn vB, Damn vB, Damn vB.

dannys

Ok,

I've posted working code at
http://phpinfo.kyboshed.com/upload.php

source:
http://phpinfo.kyboshed.com/upload.phps

robsgaming

ok one final thing, is there any way to store that tmp image in /home/virtual/site10/fst/var/www/html/imgupload/ instead of the php default tmp directory because my server admin has safe mode on....

dannys

nope - the location is controlled by the upload_tmp_dir option which can only be set in the php.ini file.

jc94062

You can upload a php.ini file into a directory that will override the main php.ini settings, I believe.

At least thats what I've read in a book, my hosters don't appear to allow it.

It may (but again I'm not sure) also be possible to override via htaccess, but thats normally used for overriding apache conf settings.

If you can't override it though, you'd have to contact the hosters and ask them to change it,
