if I choose 'php code' from the input formats when posting a forum topic, instead of parsing the php code, it just displays it..

This is critical, not normal. It makes the PHP input format useless.

Hello,

I have this issue as well and found other posts on the subject.

So far, I have not been able to resolve the issue.
Please post or email if you have a solution.

Tks in advance,

Users who want to edit PHP with TinyMCE on should use PHP Plugin This adds functionality to the toolbar and has little to do with the module. Within the module, the only option is to disable the toolbar while writing PHP.

I tried the php_plugin and enabled it but it doesn't work. When I try to use it, the code gets tranformed into useless junk. This plugin didn't work and is not a solution.

Do you have a sample of the PHP code that didn't work. This plugin has worked really well for me.

TinyMCE currently does not load when editing a page that has "PHP Code" as the import format. Couldn't that behavior be carried throughout the module? I think most people that want to edit php will be fine with a plain text area.

I agree that this is definitely a critical issue.
