WordPress MU

I have installed the plugin Calendar 2 (http://n0id.hexium.net/?page_id=56) in my site. However, since it's for WP only, i have to edit the code so as to make it compatible to WPMU.

I have a problem.
I add

 <? if (function_exists('do_calendar')) {
	do_calendar();
}	?>

in sidebar.php. The domain: mydomain/wp (admin blog) can show the calendar while /mydomain/wp/apple (user "apple"'s blog) cannot.

I would like to know why the function_exists will return false in apple blog while return true in admin blog.

Thank you.

Have you asked the plugin author?

no, but can you suggest me why it cannot find te do_calendar function if the domain is mydomain/wp/username but workable in mydomain/wp...

Thanks

Which subdirectory did you install this plugin? Can you explain how you've installed it please?

I installed the plugin in /wp-content/plugins/.

I just put the calendar folder in wp/wp-content/plugins/ and the activate the plugin with admin login.

And then i add the code

<? if (function_exists('do_calendar')) {
	do_calendar();
}	?>

in sidebar.php in wp-content/themes/default/. Then i can see the calendar in admin page but not other's blog.

Thanks

Did you activate it under the individual blog, and not just the admin one?

Really thx. i miss this. After activating it, it can display the calendar.

However, as administrator, i would like to know if i can set it active for all blogs?

That's what the mu-lplugins folder is for. It will make it active for *all* users.
You may still need to edit it a bit though. have to try it and see.

you mean i should put the calendar folder in the mu-plugin folder instead of plugin folder so i can make it active for all user?

Thank you.

i have tried put the folder in the mu-plugins folder but it does not active in other user blog...

any advice?

Thank you

Does it give you an error? Did you remember to take the copy *out* of the regular plugins folder? Did you add the function call to the other user's themes?

"i have tried put the folder in the mu-plugins folder but it does not active in other user blog..."

mu-plugins does not recognize directories inside of it.

Please search the forums here to learn about the differences between mu-plugins and plugins.

I fixed it.

Thank you so much for your help.
