[HOW-TO - vB4] Create a Custom Button for CK Editor (no file edits)

This article explains how to add or remove buttons from CKEditor by using Ckeditor and vBulletin plugins. No standard file edits needed.

To add a button to CKEditor, you need to create a CKE plugin. This is an example code for such a plugin. It will add "Hello World" to the editor and spawn a JS alert.
Important note: This article is on the technique of adding a button, not on how you will get your button to do whatever it is you want it to do. There are plenty sites out there that give support for CKEditor plugins. The CKE API documentation can be found here.

First step: Create the CKEditor plugin

The editor plugin files reside in the folder [forumroot]/clientscript/ckeplugins. Create a new folder in there. For the purpose of this article, I'll name it celButtonDemo. Inside that folder, create a file called plugin.js. So you end up with this:
[forumroot]/clientscript/ckeplugins/celButtonDemo/plugin.js
Important note: Please take notice that "celButtonDemo" will have to be replaced in the folder name and in the following code examples accordingly!.

Inside plugin.js goes the plugin code:

Code:

CKEDITOR.plugins.add( 'celButtonDemo',

{

        init : function( editor )

        {

                // This adds the button

                editor.ui.addButton('celButtonDemo',

                {

                        // label: adds a hover text to the button. This uses the vBulletin

                        // phrase "celButtonDemo" which you will have to add to your phrases

                        // and to pass to CKE in a plugin

                        label : editor.config.vbulletin.phrase.celButtonDemo,

                        // command: the command that will be executed. It's defined later

                        // in this file

                        command : 'celButtonDemo',

                        // icon: The path to the icon file you want to use for your button.

                        // Here we use buttonimage.png in the buttons directory defined for

                        // the current style (default: /images/editor)

                        icon: BBURL + '/' + IMGDIR_BUTTON + '/celButtonDemo.png',

                });



                // This defines the command that's executed when the button is clicked

                editor.addCommand('celButtonDemo',

                {

                        // modes: decide in what editor modes the button will be active;

                        // set to 0 to grey it out

                        modes : { enhancedsource:1, wysiwyg:1 },

                        // Execute your JS Code - CKE offers a great API:

                        exec: function(editor){

                                alert('Hello world!');

                                editor.insertHtml( 'Hello World! - Hello World!' );

                        }

                });

        }

});

Second step: vB Operations - register your button, add it to the toolbar, and more

In a second step we will create two vB plugins and a vB phrase. You should bundle all that together to a product, to have it all nicely together.

Let's start with the phrase: Go to AdminCP, create a phrase in the CKEditor phrase group, and name it CelButtonDemo. Enter "Hello World, hello Button" - or whatever. Save. Done.

Then create a new plugin at hook "editor_construct". This will add our button to the CKE configuration.

PHP Code:


		
			
// Add our button to the extra plugins loaded

$this->config['_extraPlugins'] .= ',celButtonDemo';

// Register our phrase for the label of our button (see second step)

$this->config['vbulletin']['phrase']['celButtonDemo'] = $this->vbphrase['celButtonDemo'];

OK, now let's create the second plugin at hook "editor_toolbar_filter":
In this example, our button will be inserted after the Quote-Button. Your options to place the button can be found in /vb/ckeditor.php. See line 7 in the following code:

PHP Code:


		
			
foreach ($toolbar AS &$row)

{

    if (is_array($row))

    {

        foreach ($row AS $id => $cmd)

        {

            if ($cmd == 'Quote')

            {

                $row = array_merge(array_slice($row, 0, $id+1),  array('celButtonDemo'), array_slice($row, $id+1));

                break;

            }

        }

    }

}

Last, not least, we need a nice little icon for our button. Upload that to /images/buttons and name it celButtonsDemo.png. Dimensions: 21x21 px.

Removing buttons

The technique used above to add the button can also be used to remove a button. Example: Removing the image button would look like that (hook "editor_toolbar_filter")

PHP Code:


		
			
foreach ($toolbar AS &$row)

{

    if (is_array($row))

    {

        foreach ($row AS $id => $cmd)

        {

            if ($cmd == 'Image')

            {

                array_splice($row,$id,1);

                break;

            }    

        }

    }

}

Please note that removing the button will not render the attached bbcode inactive! However, you can use

PHP Code:


		
			
$this->config['_removePlugins'] .= ',celButtonDemo';

at hook editor_construct to remove plugins.

Restricting buttons by editor-mode or usergroup

You have everything available to you in the vB-universe to restrict access to your button, just extend the if-condition. You can restrict by usergroup, or you can show a button only in a certain editor

The editor mode can be queried via $this->editor_type in plugins at editor_toolbar_filter:
fe = full
qr = quick reply
qe = quick edit
cms_article

Example:

PHP Code:


		
			
foreach ($toolbar AS &$row)

{

    // Condition extended: show new button only to Mods, Supermods, Admins and

    // only in Quick Reply Editor:

    if (is_array($row) AND is_member_of($vbulletin->userinfo['usergroupid'], 5, 6, 7) AND $this->editor_type == 'qr' )

    {

        foreach ($row AS $id => $cmd)

        {

            if ($cmd == 'Quote')

            {

                $row = array_merge(array_slice($row, 0, $id+1),  array('celButtonDemo'), array_slice($row, $id+1));

                break;

            }

        }

    }

}

Have fun!

Hi all, i don't know if this is the correct place, but i want to ask here.... This hack is super, but i have only need to add the "code" (standard vbulletin bbcode) in my QR - QE.

I have addedd in my qe and qr my custom bbcode (like spoiler for example) just adding this plugin via vbulletin ACP

Code:

if ($this->editor_type == 'qr' || $this->editor_type == 'qe')

{

$this->addCustomToolbarButtons();

}

Did you try what I have written in my Quick Tip here - https://vborg.vbsupport.ru/showthread.php?t=265865

Yes i did.... but please lynne, can u check my last post if mine it is a correct solution? Thanks

Great article, and I was able to accomplish what I wanted to accomplish for a single button. However, what if I wanted to add 3-4 buttons? Do I need to create unique JS files and plug-in's for each?

Thanks. Got it working great.

you can do it with one js file also, like i have done it in this mod.

This is awesome. Thanks to both of you :)

Back again -- I can't get this permissions piece of the code to work:

Code:

if (is_array($row) AND is_member_of($vbulletin->userinfo['usergroupid'], 5, 6, 7) AND $this->editor_type == 'qr' )

If I include that line, the code that follows does not execute for anyone, regardless of group. I've been trying to figure this out for a while now, and I'm totally stuck.

thanks, this is very useful.
Is there any way to use {vb:raw vboptions.xxx} in plugin.js ?

Lets say i already have a bbcode, for example the [ hide ] for the dbtech post thanks mod.
How would i add it in this example?

PHP Code:


		
			
foreach ($toolbar AS &$row) 

{ 

    if (is_array($row)) 

    { 

        foreach ($row AS $id => $cmd) 

        { 

            if ($cmd == 'Image') 

            { 

                array_splice($row,$id,1); 

                break; 

            }     

        } 

    } 

}

how is it possible to remove several button ?????

Unfortunately, no support here more or?????

I can't seem to get this to work ... did something change between 4.2 and 4.2.1?

Hello!

Great Plugin!

I want to just attach a link to my file that opens in new window. Would someone possiblly help me with that one?

Thanks a lot!

No idea what you want to do, but this article is not about attaching anything to a file, but adding a button to the editor. Please open your own thread in the appropriate forums.

Thanks for the answer!

I want to make the button link to a file in a new window. I have no idea about php and I am new to the vbulletin as well, thats why I am a bit disoriented, sorry about that. I think that what I want is simple, but I do not how to do it :(

OK. As I wrote in the article, this is not normally the place to ask for things that you want the button to do - this is for the addition of the button, not more.

Anyway: This has nothing to do with PHP - all of this is Javascript. And to open a page in a new window, you would add something like

Code:

window.open("http://www.your-page.com/goes/here.html");

to the exec part of my code. Like so:

Code:

exec: function(editor){

        window.open("http://www.your-page.com/goes/here.html");

}

For the additional syntax of window.open just google that command. There's plenty of sites explaining that.

How to move custom button to End Toolbar

By inserting it after the last button using the method described in the article.

vbb 4.2.3 not work. member can't click button... but admin can

And? The article describes how you can restrict the button per usergroup. If you don't want that, don't implement it.

i use code

Code:

foreach ($toolbar AS &$row) 

{ 

    if (is_array($row)) 

    { 

        foreach ($row AS $id => $cmd) 

        { 

            if ($cmd == 'Quote') 

            { 

                $row = array_merge(array_slice($row, 0, $id+1),  array('celButtonDemo'), array_slice($row, $id+1));

                break; 

            } 

        } 

    } 

}

course members see this button but can't click it, just administrator can click it to use
