Cannot touch physical file after uploading from this script

gdfhghjdfghgfhf · May 2, 2008

Hello,

i have a php script to upload image files. Once the image is sent, the script will upload it to a folder on my server... So far everything is good. If i install it on my old server (with php4) everything is working fine - i just have to upload the script and create the folder, not even touching the chmod's and letting the default settings. I can also access the image on my FTP and everything is good.

My problem is that i use it on a newer server, with php5. I understand nothing of this weird error.. The script is installed the same way than on the old server...

I will be able to upload the image, but my problem is when i connect to my FTP, my image is here, but i can't do anything with it.

Here is the FTP error i am getting when i try to upload any images with the script:

550 Can't open my_image.jpg: Permission denied
Can't open my_image.jpg: Permission denied

Failed [Can't open my_image.jpg: Permission denied]

I can rename the file, but i can't change the rights, and i can't transfer it from my ftp (but i can view the image in my browser)

Note that the script is uploading the big image, and it is also making a thumbnail file. I have no problem with the thumb, i can change the rights, open it, transfer it on my ftp, etc.... The only problem is around the BIG image....

Here is the code of the PHP script for uploading images:

<html dir="$stylevar[textdirection]" lang="$stylevar[languagecode]">

Someone help me plz! I'm desperate!

It's because your user nor your group hasn't got write access to the file. It's probably owned by whatever user and group your web server is running as. Only root is allowed to change the ownership using chown so you'll have to give write permissions to all.

See: http://en.wikipedia.org/wiki/File_system_permissions#Traditional_Unix_permissions

but this wouldnt explain why i have no problem with my thumbs

the script creates 2 images: the file itself, and a resized image (thumb)

if it would be a problem of permissions, isn't both images supposed to have the same problem?

gdfhghjdfghgfhf · May 6, 2008

bump

gdfhghjdfghgfhf · May 10, 2008

bump...

i still dont understand why my thumbs works and not the main image

gdfhghjdfghgfhf · May 10, 2008

i dont have ssh access to my server

there must be another way to solve this problem

help plz

BlueSkyIS · May 10, 2008

for the main image, are you creating a new one or just copying the upload. if so: since your thumb works when you create a new one, maybe try creating a new one for the main image as well.

gdfhghjdfghgfhf · May 11, 2008

i'm not sure what you mean, i have posted the code of my script in the first post...

could you help me to modify it to "create a new one for the main image" ?

mlin · May 11, 2008

don't leave your original image untouched. Resize it, without resizing it just to make sure the permissions for your thumb, and main image match.

Apache may save your upload as one user, then when you modify the original image to create a thumb, php may save as another user. So if you edit without resizing, your permissions will match.

could you give me a code as example on how to do this.... its someone from this forum who helped me to build this code, i'm pretty much confused and i dont know what to modify

i would be very grateful if you have the time to do that

mlin · May 11, 2008

down here in your code:

list($width, $height, $type, $attr) = getimagesize($target);

resample($target, 800, 800, $type, false);

resample($target, 150, 150, $type, true);

add one more call to resample...ie

resample($target, $width, $height, $type, ?);

don't know what attr does, so you'll have to double check that. and you have to make sure that tartget matches your original uploaded file.

Should be good to go
