Php photo gallery TWG | JFUploader | TWG Flash upload | WFU | Forum

I have 2 problems with TWG 1.7 :
1) TWG PHPinfo says that I have PHP 4.4.4 while my version is 5.2.1
2) Image Magick is installed on my server but TWG says that Image Magick support is not available. The path to my Image Magick is correct in config.php.
Thanks for helping

I only use the value from the php info - you can click on the phpinfo button and check there.

Are you maybe on a server where multiple php'S are installed and you can define the version on a directory level (strato does this for example).

image magick - I thest image magick by converting an image. if this fails I assume that image magic is not working properly.

What server are you using?

I tested this on windows and redhat fedora.

Michael,

My host server (ftp://ftp4.nuxit.net) is at nuxit.com

The server (Server: Apache X-Powered-By: PHP/5.2.1) does have multiple PHP (4 and 5). I use php5 (look at http://gogan.org/phpinfo.php) but TWG phpinfo give php 4.4.4

Image Magick "convert" IS installed at /usr/bin/convert and produce no error when called (convert -version => Version: ImageMagick 6.0.6 11/15/06).

call info.php of TWG and there in the right upper corner you can call the phpinfo. There you see what in your twg folder is used.

about image magick. is convert not in the path?

/Michael

Michael,

For PHPinfo, strange behaviour : when I call TWG17 directly (eg #removed_broken_link), I obtain with the phpinfo of TWGXplorer the right value (PHP-5.2.1), and the same by calling #removed_broken_link.

If I call the gallery using "http://galerie-photos.gogan.org" , ie using the sub-domain defined on nuxit.com as :
"galerie-photos.gogan.org" ==> associated to the directory "/www/twg17" (with the domain "gogan.org" ==> associated to the directory "/www" on the server)
I obtain PHP 4.4.4 using TWG info.php !

Concerning "convert", it is on the paths defined by PHP 5. I have defined the full path in "config.php" (ie /usr/bin/convert).

Paul

php: your server seems not to be configured then properly .

convert: the php exec command does not seem to find it. have you tried without the path?

/Michael

Michael,
I will investigate further with my provider as concern the behavior of PHPinfo with sub domains on their server.

For "convert" : I have tested using "PHPinteractive" (http://www.hping.org/phpinteractive/)
the PHP command :
shell_exec('convert');
and it works OK.

i only use exec - you can try shell_exec in info.php and see if there is a difference. maybe exec is not allowed on your server.

/Michael

Yes, "exec" is not allowed on my server for security reasons.

In your info.php,
function check_image_magic()

I made the following change :


//exec($command . " > /dev/null");

shell_exec($command . " > /dev/null");

No effect : I still obtain ImageMagick not available.


Paul

delete the file

_image_magick_test.jpg

in the cache folder - the check is only done once because on some servers the execute fails with a fatal error and then the page will never be displayed.

if shell_exec works i'll make a switch in the config.

/Michael

No, it does not work after deleting the file.

I have stiil the message that ImageMagick is not available


Paul

sorry - i meant

_image_magick_test.tmp.php

but the other file did exist? which size had the image?
if the size is 0 then image magick was found but the output was not o.k.

/Michael

There is no _image_magick_test.tmp.php in the cache directory.
The file _image_magick_test.jpg does exist with size 0.
Paul

what you can do:

remove the

ob_start();

and ob_end_clean();

then add an echo $command;

before
exec($command . " > /dev/null");

then you get the command that is executed.

on your server you can then execute this command in the shell.

if you don't have access then change the > /dec/null to a filesname where you can write to. And check what the error is.

/Michael

Michael,

After making the changes you suggested in info.php, we have :

echo $command;
//exec($command . " > /dev/null");
// exec($command . " > /home4/p/pgogan/www/twg17/cache/TWGerror.txt");
shell_exec($command . " > /home4/p/pgogan/www/twg17/cache/TWGerror.txt");
//shell_exec($command . " > /dev/null");

caliing twg17/info.php, I obtained :
===> _image_magick_test.jpg of size 0
===> no TWGerror.txt

echo $command returned :
convert "/home4/p/pgogan/www/twg17/buttons/info_test.jpg" -quality 80 -resize 120x81 "/home4/p/pgogan/www/twg17/cache/_image_magick_test.jpg"

and TWGinfo said : Image Magick Support Not available

*********************
In the phpinteractive shell I used :
$command = "convert /home4/p/pgogan/www/twg17/buttons/info_test.jpg -quality 80 -resize 120x81 /home4/p/pgogan/www/twg17/cache/_image_magick_test.jpg";

shell_exec($command . " > /home4/p/pgogan/www/twg17/cache/TWGerror.txt");

I obtained :
===> _image_magick_test.jpg of size 0
===> no TWGerror.txt

********************
In the phpinteractive shell I then used :

$command = "convert /home4/p/pgogan/www/twg17/buttons/info_test.jpg -quality 80 -resize 120x81 /home4/p/pgogan/www/twg17/cache/_image_magick_test.jpg";

shell_exec($command); // The redirection to a file is removed

I obtained :
===> _image_magick_test.jpg of size 3526 (OK)

****************
Then, I removed the redirection in info.php :

echo $command;
shell_exec($command);

Running twg17/info.php I obtained :
===> _image_magick_test.jpg of size 3526 (OK)
===> Image Magick Support Available

**************
Thus it appears that the redirection is the problem.
*****************

BUT, if instead of calling twg17/info.php, I call twg17 then run TWGXplorer=>Installation Check, I obtain :
===> _image_magick_test.jpg of size 0
===> Image Magick Support Not Available

THUS there is also a problem when info.php is called from within twg17
