MediaWiki+FCKeditor : shared images not working

Reported by: cvh Owned by:
Priority: Must have (possibly next milestone) Milestone:
Component: Project : MediaWiki+FCKeditor Version: FCKeditor 2.5.1
Keywords: shared tables interwiki Cc: admin@…


I use 3 wiki for multilingual purposes: 1 french, 1 dutch and 1 global that is configured shared upload of images

The code for the images of the existing images is transformed when i preview or clik on the wikitext button

Steps to reproduce: open a page in the wiki: the image are correctly shown click on edit: i still see the images click on the wikitext button to see the "source" code:

the link for the first image was :


and it becomes: [[Image:|Image:But_harm_afwezig.png]]

Moreover when i try to place a new image, the dialog box does'nt let me access tio the shared folder of images but still in the local images

parameters in LocalSettings.php: $wgUploadNavigationUrl="http://localhost/mediawiki/index.php/Special:Upload"; ##to use pool's wiki file in language wiki

$wgUseSharedUploads = true; $wgSharedUploadPath = 'http://localhost/mediawiki/images'; $wgSharedUploadDirectory= 'C:
'; $wgHashedSharedUploadDirectory = true;

Please check ticket 1293 for first issue.

On MW website, it contradicts your setting:


Set this setting to false especially if you have a set of files that need to be accessible by all wikis, and you do not want to use the hash (path/a/aa/) directory layout.

It's true though that the Ajax call in FCK is only looking at the DB for the file, not the shared directory.

To avoid the problem described,I tried to stop sharing the images and to create 2 totally independant wiki's. I made 2 folders: wikif & wikin, 2 databases: wikif & wikin. in the folders images of /wikin and /wikif I made a copy of the shared folder images (every images copied twice). Then I executed the script to create the image pages updating the tables page, revision and text. I managed to do it but I still had a problem: wiki could not find the text of the image pages. May be an error in my script or may be I forgot to take in account another table I place the script in attachment for your curiosity, any feedback is welcome.

to understand this script: the database has been copied in db wikif and contains

  • without prefixe: the pool tables (containing image pages)
  • with prefixe fr_ the tables of the french wiki
/* insert image pages from the pool to the fr_ table */
	insert into wikif.fr_page
	 `page_namespace`, `page_title`, `page_restrictions`, `page_counter`, `page_is_redirect`, `page_is_new`, `page_random`, `page_touched`, `page_latest`, `page_len`
	 `page_namespace`, `page_title`, `page_restrictions`, `page_counter`, `page_is_redirect`, `page_is_new`, `page_random`, `page_touched`, `page_latest`, `page_len`
	from where page_namespace=6;

select * from wikif.revision where rev_page in 
	(select page_id from where page_namespace=6);

/** creation of the table to keep link between pool's page_id's and the pages i,serted in fr_page **/
create temporary table wikif.tempage (page_id int, text_id int, new_page_id int);

insert into wikif.tempage (page_id, text_id , new_page_id )
	select rev_page, rev_text_id ,0 from wikif.revision
	where rev_page in (select page_id from where page_namespace=6);

update wikif.tempage as t, fr_page as fp, page as ep
	set t.new_page_id= fp.page_id where fp.page_title=ep.page_title and t.page_id=ep.page_id;

select * from wikif.tempage;

CREATE TEMPORARY TABLE  wikif.temp_revision_table LIKE wikif.revision;

insert into wikif.temp_revision_table select revision.* from wikif.revision

Found the solution:

Assume, you only want to search your pool wiki for images, you have to set the praefix for the right table. Look for

"$res = $db->select( 'page', 'page_title',"

in FCKeditoSajax.body.php (line 74) and rename it to:

"$res = $db->select( 'YOUR_POOL_PRAEFIX_page', 'page_title',"

So it is done, FCKeditor find the right images. It is only a little bit hardcoded by me :-)

I found a way to let the FCK editor files untouched:

When you use shared wikis, you have to replace some code in the database.php and modify the function tableName() in localSettings.php:

function tableName( $name ) {

global $wgSharedDB; global $wgSharedTables; global $wgSharedPrefix; # Skip quoted literals] if ( $name{0} != '`' ) {

$found = 0; if ( $this->mTablePrefix !== && strpos( '.', $name ) === false ) {

$name = "{$this->mTablePrefix}$name";


if ( isset( $wgSharedDB ) ) {

foreach ($wgSharedTables as $fromshared) {

if ($name == $fromshared) {

$name = "$wgSharedDB.$name"; #you may add $wgSharedPrefix here $found = 1;




if ($found == 0) {

# Standard quoting $name = "$name";


} return $name;


In LocalSettings.php:

$wgSharedDB = 'wiki'; set to your shared db name $wgSharedTables = array( 'user', 'user_groups', 'interwiki', 'ipblocks'); some examples of useful shared tables

$wgSharedPrefix = ; change it to the correct prefix. In my case it would be "pool_"
