PHP & Image Manipulation - File Permissions?

crash

2006-02-12, 6:31 pm

I've got some problematic code that's interacting with a new server. I need
some PHP expertise to help me out with it. I did not develop the page, and
the only thing I really know about PHP is how to spell it.

Here is the errors that I am receiving & the code on the pages. I'm trying
to wade through this, but I'm not PHP native and I'm not sure I'm following
entirely what's going on. It appears to be a permissions issue - can
somebody help me with what permissions I might need to enable? I have
removed information I think might need to be, if it looks like you need some
of it, please let me know.

The error(s):

Warning: mkdir(../rental/rental_images/39): Permission denied in
/***/****/public_html/admin/admin_image_csize.php on line 60

Warning: Cannot modify header information - headers already sent by (output

What is the full, root-relative path to adm_image_upload.php?

I got it Gary. I thought file permissions were being set in the PHP file,
but apparently they needed to be set on the directory to allow it to set
permissions on the actual files.

Still learning all the ins and outs of PHP. Quite a mouthful.

Thanks for your attention, I really appreciate your quick response.

Yep. If the script doesn't have the permissions, it cannot *set* the
permissions. ;-)

No problem, Jon. Post back if you need assistance in your journey.
