Hi guys, I've had a fair bit of luck with the help I've gotten off you in the past so hopefully you can help me here.

I'm creating a photo gallery component for my new site, during the installation of the component it creates all the necessary files and folders, including the folder I wish to save user submitted photos to. This folder is in the directory components/com_photoalbum/images. However my script can not save files to this folder as by default the permission are 755. If I manually change the permissions to 777 it works fine.

It may seem like this isn't a problem, but I'd like to publish this component in the JED and want set up to be as easy and secure as possible, and don't want people to have to chmod that directory themselves.

I've tried this code in my script chmod("components/com_photoalbum/images", 0777); but this doesn't work.

What can I do to make a that directory writeable from my script? If it makes a difference my test site runs on PHP 4, but i also want it to work on PHP 5. Also when i install the component I'm installing from my tmp directory rather than uploading the .zip via FTP

Any help would be greatly appreciated, and would help me share my work with the community.

Nobody will use your component under those conditions!
I thought I read somewhere that you can only go one folder deep on the media directory with components.

Otherwise you may have some local permission setup issues. Are all the user and group permissions correct on your files?

Can you set the photo gallery to use the /images directory off the root?

check if the owner of the directory is same as others below it (should be same as httpd process owner).
It is odd that if the directory was created by the script, that it should already have full access to it, since its the same process (owner).

Why? Whats the problem with chmoding a folder to 777, saving a file then chmoding it back to 755. Why would nobody use this?.


Yeah I though about that, had a look and all the directories in the /images folder off the root area also 755. Also how would I create a new folder in that directory during the install of my component? Can't you only create directories in the admin and front end directories of you component?

ok looks like this page may help me and any other people who have this issue
http://docs.joomla.org/How_to_use_the_f ... em_package
But if anyone has any experience in how to do this I'd like to hear from you.

This now seems to be working if I use the php mkdir function, but is this safe? Is this a security vulnerability and is there a better way to do this in Joomla?

Maybe strange question: Why do you want a 777 chmod on a folder?
755 should be good enough..

THe problem isn't your component, the problem is your server.

Make sure that the PHP/Apache user is the user that owns your files and directories. 755 and 644 should be sufficient if your server is setup properly. You also should be using JFile rather than directory PHP file system calls so that your extension will automatically use the FTP layer if it is enabled.
