WordPress MU

Hi all , I was looking for "Theme Editor" for my WordPress MU 2.8.1 and since it was disabled and by searching online looked like there are not that many good suggestions I looked at the code and if anyone wants to have The built-in Theme Editor they will need to edit one (1) file only and does not need to upload anything.

File is "mu.php" located under "/wp-admin/includes" folder.

to edit from WordPress MU 2.8.1:
line 532
from: "unset( $submenu['themes.php'][10] ); // always remove the themes editor"
to: "//unset( $submenu['themes.php'][10] ); // always remove the themes editor"

line 1190
from :"if ( strpos( $_SERVER['PHP_SELF'], $page ) ) {"
to:"if ( strpos( $_SERVER['PHP_SELF'], $page ) && !is_site_admin() ) {"

and by searching online looked like there are not that many good suggestions

that's because they were all suggestions that worked previous to 2.8.1, which changed how the theme editor was disabled.

Glad you tracked it down.

Around line 1174 blank out the following also:

/*
$pages = array( 'theme-editor.php', 'plugin-editor.php' );
foreach( $pages as $page ) {
if ( strpos( $_SERVER['PHP_SELF'], $page ) ) {
wp_die( __('Page disabled by the administrator') );
}
}
*/

/*
$pages = array( 'theme-editor.php', 'plugin-editor.php' );
foreach( $pages as $page ) {
if ( strpos( $_SERVER['PHP_SELF'], $page ) ) {
wp_die( __('Page disabled by the administrator') );
}
}
*/

actually you don't need to remove them , just need to change to "if ( strpos( $_SERVER['PHP_SELF'], $page ) && !is_site_admin() ) {" so that only Admin have access to it ..

Remember though, if you change a theme, it changes for ALL blogs that have that theme. And if you make an error on that theme, then all the blogs using it will be unavailable until you fix it.

Just saying.

Yep. But it's a handy workaround if you're trying to tweak a theme before going live and ftp is taking for-freaking-ever. ;P

I wound up needing to re-enable the theme editor for a client who's used to using it. Of course you always want to be careful when editing themes on MU because the changes are global (affect all blogs/sites using the install).

Initially, I wanted to try something like:
remove_action( 'admin_init', 'disable_some_pages' );

in my plugin, which, of course, doesn't work. But since I really like to tread lightly when editing core files, I wasn't happy making all the changes suggested here in the core. I wound up instead commenting out:
add_action( 'admin_init', 'disable_some_pages' );
from line 1205 of /wp-admin/includes/mu.php and adding in my own customized 'disable_some_pages' function into the plugin (copied the core function, then edited it inside of the plugin).

My 'disable_some_pages' function is wrapped into a class that owns the plugin, so I add it back in like this:
add_action( 'admin_init', array ( &$myPluginNameHere, 'disable_some_pages' ));

I'd publish more of the source code here, but it's a premium plugin I'm working on for a specific client, and I don't think they'd be too happy with me if I did.

Anyhow, hope that's at least somewhat helpful as a possible alternate approach.

Btw, I also chose to modify the 'if' statements with && is_site_admin() to re-enable the pages I wanted to have available.

Just as an update on this, in 2.8.4a

this change is on line 55 not 532
from: "unset( $submenu['themes.php'][10] ); // always remove the themes editor"
to: "//unset( $submenu['themes.php'][10] ); // always remove the themes editor"

this change is on line 1218 not 1190
from :"if ( strpos( $_SERVER['PHP_SELF'], $page ) ) {"
to:"if ( strpos( $_SERVER['PHP_SELF'], $page ) && !is_site_admin() ) {"

you guys are Godsends =D
thanks.

When using the "userthemes" plugin, the new version seems to activate the theme editor on a blog by blog basis, which seems safer to me. Performing the edits above will produce what seems to be 2 theme editors in the left menu of the blog using userthemes. Using the userthemes plugin seems to make it easier on the admin, not having to enable the them editor as stated above.

This is a great thread, don't get me wrong. I'm sure there is a scenario when the steps above are needed vs. using userthemes. I just thought I'd mention this as I'm doing the latter.

As far as I know, the userthemes plugin gives each user their own copy of the theme to work with. themes are no longer shared in that case.

I've enabled the theme editor as above in some cases because it's been quicker than other ways I had available for quick theme edits (while doing dev work), or it's my own install or a locked-down install.

In other installs I've one of the CSS editor plugins for users to tweak & override the css of their themes.

I'm sorry but I didn't understand what I have to do.
Can you resum please from the beginin ?

Update on 2.8.5.2

The changes are on line 556 and 1128 instead of 532 and 1190

Just want to say, this works, and is awesome! Thanks a lot!

Note: I am a n00b at this

Didnt work for me :(

I have WPMU and BuddyPress running before i tried to change the mu.php file. Nothing i've done to the mu.php file seems to work. Heck, i even changed the error message hoping to see if it was reaching there but for some reason it wasn't.

Neo2000: That's usually a sign that you are editing the wrong file... :)

The plugin "Userthemes Revisited" doesn't work on my Wordpress MU 2.8.4 with Buddypress 1.1.3.

The entire plugin features work except for the editor window itself.

http://wpmudevorg.wordpress.com/project/Userthemes-Revisited

Locations for v2.9.1 are 697 and 1378.

I am guessing that this will be an option inside the admin interface going forward after the merge. Does anyone know?

It isn't so far.

Feel free to file a trac ticket.

http://core.trac.wordpress.org

I filed a ticket here

In the mean time I found a plugin to do this for anyone looking to do this without hacking the core files.

http://wordpress.org/extend/plugins/enable-theme-and-plugin-editor/

Opps, there was a ticket already started for this here. Lots of discussion on this in that ticket.

Looks like for now its been enabled in the current codebase. Grabbing the latest copy is another option to get the editor back.

I found that the location in WPMU v2.9.2 was line 569 and line 1147.

Thanks for writing this up. For quick tweaks to a theme it's nice to offer site admins the option of using the Theme Editor.

And in 3.0 it's enabled for super admins by default.
