Usage
Configure actions
For using elFinder you must create and configure controller. See complete example with actions for elFinder's connector,
InputFile
widget, CKEditor filebrowser*
options and TinyMCE file_picker_callback
option:
<?php namespace app\controllers; use alexantr\elfinder\CKEditorAction; use alexantr\elfinder\ConnectorAction; use alexantr\elfinder\InputFileAction; use alexantr\elfinder\TinyMCEAction; use Yii; use yii\web\Controller; class ElfinderController extends Controller { public function actions() { return [ 'connector' => [ 'class' => ConnectorAction::className(), 'options' => [ 'roots' => [ [ 'driver' => 'LocalFileSystem', 'path' => Yii::getAlias('@webroot') . DIRECTORY_SEPARATOR . 'uploads', 'URL' => Yii::getAlias('@web') . '/uploads/', 'mimeDetect' => 'internal', 'imgLib' => 'gd', 'accessControl' => function ($attr, $path) { // hide files/folders which begins with dot return (strpos(basename($path), '.') === 0) ? !($attr == 'read' || $attr == 'write') : null; }, ], ], ], ], 'input' => [ 'class' => InputFileAction::className(), 'connectorRoute' => 'connector', ], 'ckeditor' => [ 'class' => CKEditorAction::className(), 'connectorRoute' => 'connector', ], 'tinymce' => [ 'class' => TinyMCEAction::className(), 'connectorRoute' => 'connector', ], ]; } }
Reed elFinder docs to configure connector options.
InputFile widget
Example of InputFile
widget with enabled mime filter and preview:
<?= alexantr\elfinder\InputFile::widget([ 'name' => 'attributeName', 'clientRoute' => 'elfinder/input', 'filter' => ['image'], 'preview' => function ($value) { return yii\helpers\Html::img($value, ['width' => 200]); }, ]) ?>
Note 1: Filter option is using to display only certain files based on their mime type. Check onlyMimes
option
in elFinder docs.
Note 2: Preview displays only predefined (saved earlier) input value and not updating on the fly after new selection.
If you want to use the InputFile
widget in ActiveForm
, it can be done like this:
<?= $form->field($model, 'attributeName') ->widget(alexantr\elfinder\InputFile::className(), [ 'clientRoute' => 'elfinder/input', ]) ?>
Using textarea instead text input (can be useful with enabled multiple selection):
<?= alexantr\elfinder\InputFile::widget([ 'name' => 'attributeName', 'clientRoute' => 'elfinder/input', 'textarea' => true, 'textareaRows' => 3, // default is 5 ]) ?>
Enable multiple selection to select more than one file in one input:
<?= alexantr\elfinder\InputFile::widget([ 'name' => 'attributeName', 'clientRoute' => 'elfinder/input', 'multiple' => true, ]) ?>
Default paths separator for text input is comma and newline character for textarea.
You can change them in InputFileAction
configuration:
class ElfinderController extends Controller { public function actions() { return [ // ... 'input' => [ 'class' => InputFileAction::className(), 'connectorRoute' => 'connector', 'separator' => ',', 'textareaSeparator' => '\n', // newline character in javascript ], // ... ]; } }
Integration with CKEditor
For using elFinder with CKEditor widget (like this one) you need to
specify options filebrowserBrowseUrl
and (or) filebrowserImageBrowseUrl
:
<?= alexantr\ckeditor\CKEditor::widget([ 'name' => 'attributeName', 'clientOptions' => [ // ... 'filebrowserBrowseUrl' => yii\helpers\Url::to(['elfinder/ckeditor']), 'filebrowserImageBrowseUrl' => yii\helpers\Url::to(['elfinder/ckeditor', 'filter' => 'image']), ], ]) ?>
Note: For filebrowserImageBrowseUrl
we use filter query param to display only images.
Integration with TinyMCE 4 & 5
For using elFinder with TinyMCE widget (like this one) you need to
specify option file_picker_callback
:
<?= alexantr\tinymce\TinyMce::widget([ 'name' => 'attributeName', 'clientOptions' => [ // ... 'file_picker_callback' => alexantr\elfinder\TinyMCE::getFilePickerCallback(['elfinder/tinymce']), ], ]) ?>
Note: option file_picker_callback
available since 4.1.0 version of TinyMCE js plugin.
With second param in getFilePickerCallback()
you can set additional settings for
tinymce.activeEditor.windowManager.open
(TinyMCE 4) or tinymce.activeEditor.windowManager.openUrl
(TinyMCE 5):
TinyMCE::getFilePickerCallback(['elfinder/tinymce'], ['width' => 1200, 'height' => 600])
Standalone file manager
Add ElFinder
widget to any view:
<?= alexantr\elfinder\ElFinder::widget([ 'connectorRoute' => ['elfinder/connector'], 'settings' => [ 'height' => 640, ], 'buttonNoConflict' => true, ]) ?>
Note: If you are using Bootstrap 3 enable buttonNoConflict
option to resolve conflict between
Bootstrap and jQuery UI buttons.
