disable the upload tab

You can customize the dialogs as shown in the api_dialog.html sample.
This code will remove the upload tab in image and link dialogs:

CKEDITOR.on( 'dialogDefinition', function( ev )
   {
      // Take the dialog name and its definition from the event
      // data.
      var dialogName = ev.data.name;
      var dialogDefinition = ev.data.definition;

      // Check if the definition is from the dialog we're
      // interested on (the Link and Image dialog).
      if ( dialogName == 'link' || dialogName == 'image' )
      {
         // remove Upload tab
         dialogDefinition.removeContents( 'Upload' );
      }
   });

I'm using CKEditor bundled with an older version of Opencart and I want to remove the 'Upload' tab from both the Image and Link dialogs.

I've used the code provided by alfonsomi, and it works perfectly for the Image dialog, but not for the Link dialog. Has anyone else come across this? It's very frustrating.

Any help would be much appreciated.

i managed to get it working using:
CKEDITOR.on( 'dialogDefinition', function( ev ) {
// Take the dialog name and its definition from the event data
var dialogName = ev.data.name;
var dialogDefinition = ev.data.definition;
if ( dialogName == 'image' || dialogName == 'link' ) {
// Remove upload tab
dialogDefinition.removeContents('Upload');
dialogDefinition.removeContents('upload');
}
});

looks like the image uses Upload and link uses upload - CASE SENSITIVE

Currently there's a simpler way using the removeDialogTabs option
so you can set in your config:

config.removeDialogTabs = 'link:upload;image:Upload';

If you have to find the name of other dialogs or tabs, use the DevTools plugin (available in the _samples folder)

I'm using CKEditor for Drupal and trying to remove the Upload tab but keep 'Browse Server' functionality (...want users to use file upload functionality in CKFinder).

I've tried setting the follow in my config.js and it's not working (ignored at runtime):

config.removeDialogTabs = 'link:upload;image:Upload'

Is the code below placed in the config.js file?

CKEDITOR.on( 'dialogDefinition', function( ev ) {
// Take the dialog name and its definition from the event data
var dialogName = ev.data.name;
var dialogDefinition = ev.data.definition;
if ( dialogName == 'image' || dialogName == 'link' ) {
// Remove upload tab
dialogDefinition.removeContents('Upload');
dialogDefinition.removeContents('upload');
}
});
