CKEditor Widget for Yii2
Renders a CKEditor WYSIWYG text editor plugin widget.
Installation
The preferred way to install this extension is through composer.
Either run
composer require 2amigos/yii2-ckeditor-widget
or add
"2amigos/yii2-ckeditor-widget" : "~2.1"
to the require section of your application's composer.json file.
Skins & Plugins
This widget works with default's dev-full/stable branch of CKEditor, with a set of plugins and skins. If you wish to
configure a different skins or plugins that the one proposed, you will have to download them separately and configure
the widget's clientOptions attribute accordingly.
Usage
The library comes with two widgets: CKEditor and CKEditorInline. One is for classic edition and the other for inline
editing respectively.
Using a model with a basic preset:
use dosamigos\ckeditor\CKEditor;
<?= $form->field($model, 'text')->widget(CKEditor::className(), [
'options' => ['rows' => 6],
'preset' => 'basic'
]) ?>
Using inline edition with basic preset:
use dosamigos\ckeditor\CKEditorInline;
<?php CKEditorInline::begin(['preset' => 'basic']);?>
This text can be edited now :)
<?php CKEditorInline::end();?>
How to add custom plugins
This is the way to add custom plugins to the editor. Since version 2.0 we are working with the packagist version of the
CKEditor library, therefore we are required to use its configuration API in order to add external plugins.
Lets add the popular Code Editor Plugin for example. This plugin would allow us to
add a button to our editor's toolbar so we can add code to the content we are editing.
Assuming you have downloaded the plugin and added to the root directory of your Yii2 site. I have it this way:
We can now add it to our CKEditor widget. For this example I am using CKEditorInline widget. One thing you notice on
this example is that we do not use the preset attribute; this is highly important as we want to add a customized toolbar to our
widget. No more talking, here is the code:
<?php
use dosamigos\ckeditor\CKEditorInline;
// First we need to tell CKEDITOR variable where is our external plugin
$this->registerJs("CKEDITOR.plugins.addExternal('pbckcode', '/pbckcode/plugin.js', '');");
// ...
// Using the plugin
<?php CKEditorInline::begin(['preset' => 'custom', 'clientOptions' => [
'extraPlugins' => 'pbckcode',
'toolbarGroups' => [
['name' => 'undo'],
['name' => 'basicstyles', 'groups' => ['basicstyles', 'cleanup']],
['name' => 'colors'],
['name' => 'links', 'groups' => ['links', 'insert']],
['name' => 'others', 'groups' => ['others', 'about']],
['name' => 'pbckcode'] // <--- OUR NEW PLUGIN YAY!
]
]]) ?>

</p>
<?php CKEditorInline::end() ?>
Browse & Upload
To browse and upload files, the KCFinder plugin is used, which is disabled by default.
To enable it, just use 'kcfinder'=>true.
See this simple example code:
<?php
use dosamigos\ckeditor\CKEditor;
echo $form->field($model, 'text')->widget(CKEditor::className(), [
'kcfinder' => true,
]);
The upload folder name is upload in the root web directory by default.
You can set options for the kcfOptions parameter, and can find all KCFinder's options in this link: https://kcfinder.sunhater.com/install
For change upload directory or change some options you can see this advanced example code:
<?php
use dosamigos\ckeditor\CKEditor;
echo $form->field($model, 'text')->widget(CKEditor::className(), [
'kcfinder' => true,
'kcfOptions' => [
'uploadURL' => '@web/upload',
'uploadDir' => '@webroot/upload',
'access' => [ // @link http://kcfinder.sunhater.com/install#_access
'files' => [
'upload' => true,
'delete' => true,
'copy' => true,
'move' => true,
'rename' => true,
],
'dirs' => [
'create' => true,
'delete' => true,
'rename' => true,
],
],
'types' => [ // @link http://kcfinder.sunhater.com/install#_types
'files' => [
'type' => '',
],
],
],
]);
About extra assets
You maybe wonder why there is file dosamigos-ckeditor.widget.js. The reason is that due to the way Yii2 works with
forms and Cross-Site Request Forgery (csrf). CKEditor does not trigger the on change event nor collects the CSRF token
when using file uploads.
The asset tackles both issues.
Testing
To test the extension, is better to clone this repository on your computer. After, go to the extensions folder and do
the following (assuming you have composer installed on your computer):
$ composer install --no-interaction --prefer-source --dev
Once all required libraries are installed then do:
$ vendor/bin/phpunit
