Problem with imagecreatefromjpeg();

[mjurmann]

Hi guys, I'm having a real tough time here.


I've recompiled Apache with the gdlib in WHM; however, when I attempt to run:

error_reporting(E_ALL);

// This is the temporary file created by PHP
$uploadedfile = $_FILES['uploaded2']['tmp_name'];

echo $uploadedfile;
echo "<br/>";
echo "<br/>";

// Create an Image from it so we can do the resize

$src = imagecreatefromjpeg($uploadedfile);
var_dump($src);

I get this:

Warning: imagecreatefromjpeg(/tmp/phpk8YWjD) [function.imagecreatefromjpeg]: failed to open stream: No such file or directory in /home/gameargu/public_html/cms/htms/admin-games-image-uploaded.php on line 312
bool(false)

I can't figure out why my temporary images are not saving on the server. Is there a setting I need to change in WHM? Please help...

Seems like you have permission issues to the /tmp/. Check that you can read/write to /tmp.

[mjurmann]

Bin, first of all, thank you for helping me.

Second, is the /tmp/ it is referring to the /tmp/ in my root, or is it the /tmp/ in the directory relative to where my script is?

[bin_asc]

In the root. The /tmp/ partition. When you ssh in, type ls, you should see the /tmp

[mjurmann]

Is there a way to see what the default permissions are for that directory in SSH? A command?

ls -alt /|grep tmp

I chmoded tmp in the root to 777 and then ran ls -l. The result was: drwxrwxrwx

It's still not working...that is why I'm not sure if the command imagecreatefromjpeg is pointing to the right /tmp/ dir

[bin_asc]

It is. I can take a look tomorrow at it, if you`d like, now I`m heading for zZzZz ... late here, good luck either way

First thing you'll want to do is chmod /tmp back to what it was before you changed it to 777. chmod'ing 777 is not the answer.

Randomly chmoding directories (especially /tmp) to 777 puts you well on your way to getting rooted - because I'm also guessing you don't have /tmp mounted noexec, probably aren't running phpsuexec or suexec, and probably aren't running mod_security.

Alright Mike, I chmoded it back to what it was.

Do you have any idea why I'm getting this error? This function worked fine on the 3 shared servers I was on before this dedicated server that I'm using.

[mjurmann]

This is so confusing to me because according to phpinfo():


Configure command:

--with-gd' '--with-jpeg-dir=/usr/local'

gd
GD Support enabled
GD Version bundled (2.0.28 compatible)
GIF Read Support enabled
GIF Create Support enabled
JPG Support enabled
PNG Support enabled
WBMP Support enabled
XBM Support enabled

Everything looks enabled and I just can't figure out why it won't put the file in the tmp directory

I'm also guessing you don't have /tmp mounted noexec, probably aren't running phpsuexec or suexec

I'm guessing this is the very problem. Try moving the file to your the account's directory first and then creating from it. You might not be able to execute in tmp because of one of the above.

"Try moving the file to your the account's directory first and then creating from it. You might not be able to execute in tmp because of one of the above."

Could you please explain this to me a little better? What file do I need to move to what directoy?

[mtindor]

I think he is saying that you should get your application to use /home/your_account_name/tmp as the temp directory instead of it using the default /tmp - because of the way permissions may be set on /tmp.

Also - Via SSH:

ls -alt / |grep tmp
- show the results to us

mount |grep tmp
- show the results to us

This way we can see what perms are on your /tmp directory and what mount directives were used.

ls -alt / |grep tmp

drwxrwxrwx 7 gameargu gameargu 4096 Sep 25 16:38 tmp

mount |grep tmp

none on /dev/shm type tmpfs (rw)
/dev/sda7 on /tmp type ext3 (rw,noexec,nosuid)
/tmp on /var/tmp type none (rw,noexec,nosuid,bind)

How do I go about telling an application to use a different temp directory other than the default tmp/ ?
