Php script works local but not on the server.

[guille]

I found a script to display a simple photo gallery with dynamic thumbnails. I modified the script to make it save the photo thumbnails. It works perfect here in my computer but when i upload to my hosting it doensīt seem to work.

Here the script:

function draw_image($src) {
global $size;
list($width, $height, $type, $attr) = getimagesize($src);

if($size == 'full') {
$img = imagecreatefromstring(file_get_contents($src));
} else {

if(file_exists(stripslashes(PATHT.$_REQUEST['src']))){
imagedestroy($img);
$img=imagecreatefromjpeg(urldecode(stripslashes(PATHT.$_REQUEST['src'])));
} else {
$img = imagecreatefromstring(file_get_contents($src));
$lowest = min(THMBWIDTH / $width, THMBHEIGHT / $height);
if($lowest < 1) {
$smallwidth = floor($lowest*$width);
$smallheight = floor($lowest*$height);
$tmp = imagecreatetruecolor($smallwidth, $smallheight);
imagecopyresized($tmp, $img, 0, 0, 0, 0, $smallwidth, $smallheight, $width, $height);
imagedestroy($img);
$img = $tmp;

$file = urldecode(stripslashes(PATHT.$_REQUEST['src']));
imagejpeg($img,$file);
}
}

}

mostrar($type,$img);
imagedestroy($img);

I'd appreciate any feedback ...totally lost here...

do you get errors?

can you explain "doesn't work" a little better?

and a word of advice, don't use $_REQUEST, it is a security concern, specify $_POST or $_GET

you should never use $_REQUEST

The script doesnīt return anything... no images.
I think the problem is here:"if(file_exists(stripslashes(PATHT.$_REQUEST['src'])))".
I donīt get any error mesage, just the images not drawing.

Now i will take a look at Post and Get.. to find how to use them (iam a programmer but new to php).

Thanks in advance.

I don't see where that is supposed to be coming from, you would think it is supposed to be a constant, though I don't see it being set.

hmmm, maybe try changing all occurences of PATHT.$_REQUEST['src'] with $src as $src seems to be the image path

I think you have display_errors [php.net] turned off in your php.ini as well because that should be giving you a parse error. It also may just be that error_reporting [php.net] is set too low.

You may also want to look at the permissions of the folder where you save the images.

Also, do you have the same php version in your pc as in your server? Can you check for differences? Many new image scripts use the php5 functions, while most servers are at 4.x.

here i post all the complete code....

[edit reason] no urls as per T.O.S [webmasterworld.com].Thanks [/edit]

try inserting a little line which will make it print out the images's URL onto the page. then you can at least see if the URL is pointing to the right place. if it's stripping out the slashes from the URL then you will be able to see.
