Do an exec after uploading file?

[Anon]

Hello!
I do an upload with php and it works fine. But after the upload, I would like to execute a command. - In my case I would like to use Imagemagick to resize the graphic.
But if I put exec("convert -size 100x200 $image folder/$image_name");

it does not work - why?
it does work when I am not using an upload:
E.g.

exec("convert -size 100x200 somepic.jpg folder/somepic.jpg");

can anyone help me on this please?
thanks, saman

Have you made sure that the file you just uploaded is in that directory? PHP typically wants to put any uploaded files into the /tmp directory with a unique name.

Yes, I am pretty sure, that the file is in that directory:

here is the snippet which will handle the upload:

####
if ($picture_name != "") {
copy("$picture",
"/usr/local/home/saman/public_html/images/artbilder/$picture_name")
or die("Couldn't copy the file!");
echo("picture uploaded");
exec("cp $picture ../images/artbilder ../images/artbilder/resized/$picture_name");
####

• the problem is, that I don't know, when and where to use either "$picture" or "$picture_name" - Can someone help me on my problem? - thanks, saman

Well it helps to know what $picture and $picture_name are supposed to be. I'd assume that $picutre_name is the name of the file, but that's not a guarantee.

Print out both $picture, and $picutre_name before this code to see what they are.

If $picture is the value of the input field type=file from your form then this code isn't going to work.
