Q: Site Design - Should I enable output (zlib/gzip) compression in my scripts?

NEVER enable Output Compression.

Output compression (also called zlib/gzip output) will compress your data before sending it out.

NEVER enable this.

The data goes from your user server, to front end servers (load balanced) which worry about all compression between users browsers and themselves. They do the compression extremely well and if you send compressed data back to them (they explicitly set headers saying not to, but you have set the script to always to it), they recompress the data and break it.

Q. Site Design - How Do I Allow a PHP Script to Write to a Folder?

Q. How Do I Allow a PHP Script  to Write to a Folder?

A. This answer also applies to file uploads!

The web server runs as a different user than you. To enable php scripts to write files or file uploads to be copied into your site folder, you need to set a folder to be "world writeable".

If you are using an FTP client, you would issue the command chmod 777 foldername. Some ftp clients are more graphical so you want everyone - the user, group and everyone to have write, read and execute permissions. 777 looks like this in some displays: rwxrwxrwx. Normally the permissions for folders are 755 which look like this: rwxr-xr-x

If you are using the file manager in CWahi, check the box beside the folder that you want to change, then check mark ALL of the boxes and save.

This will give your scripts the ability to write to your folders.

Q: Site Design - Can I install ANY php script onto CWahi?

Q. Can I install ANY php script onto CWahi?

A. That depends. If the scripts requires a disabled function, then no. See the list of php functions in the My Account tab in your profile.

If you successfully install a script, please consider providing a written up "How-To" to add to our tutorials section to aid other members. With members helping members, "Everyone Wins"!

Note: If you want the ability to install any script you wish, you need a Crosswinds One account (professional unlimited hosting), which can be found here: http://www.crosswinds.net/
