Usage
Upload file
Attach the behavior in your model:
class Document extends ActiveRecord { /** * @inheritdoc */ public function rules() { return [ ['attachment', 'file','maxFiles' => 2, 'extensions' => 'doc, docx, pdf', 'on' => ['insert', 'update']], ]; } /** * @return \yii\db\ActiveQuery */ public function getCategory() { return $this->hasOne(Category::className(), [ 'id' => 'id_category' ]); } /** * @inheritdoc */ function behaviors() { return [ [ 'class' => UploadBehavior::className(), 'attributes' => [ [ 'attribute' => 'attachment', 'path' => '@webroot/upload/docs/{category.id}', 'url' => '@web/upload/docs/{category.id}', //'multiple' => true, //'multipleSeparator' => '|', //'nullValue' => '', //'instanceByName' => false, //'generateNewName' => true,//function($file){return uniqid().$file->name.;} //'unlinkOnSave' => true, //'deleteTempFile' => true, //'scenarios' => ['insert', 'update'], ], [ .... ] ], //'multipleSeparator' => '|', //'nullValue' => '', //'instanceByName' => false, //'generateNewName' => true,//function($file){return uniqid().$file->name.;} //'unlinkOnSave' => true, //'deleteTempFile' => true, 'scenarios' => ['insert', 'update'], ], ]; } }
Example view single file:
<?php $form = ActiveForm::begin(['options' => ['enctype' => 'multipart/form-data']]); ?> <?= $form->field($model, 'attachment')->fileInput() ?> <div class="form-group"> <?= Html::submitButton('Submit', ['class' => 'btn btn-primary']) ?> </div> <?php ActiveForm::end(); ?>
Example view multiple file:
<?php $form = ActiveForm::begin(['options' => ['enctype' => 'multipart/form-data']]); ?> <?= $form->field($model, 'attachment')->fileInput([ 'name' => Html::getInputName($model, 'attachment').'[]', 'multiple' => true, ]) ?> <div class="form-group"> <?= Html::submitButton('Submit', ['class' => 'btn btn-primary']) ?> </div> <?php ActiveForm::end(); ?>
Upload image and create thumbnails
Attach the behavior in your model:
class User extends ActiveRecord { /** * @inheritdoc */ public function rules() { return [ ['image', 'image', 'extensions' => 'jpg, jpeg, gif, png', 'on' => ['insert', 'update']], ]; } /** * @inheritdoc */ public function behaviors() { return [ [ 'class' => \liyunfang\file\UploadImageBehavior::className(), 'attributes' => [ [ 'attribute' => 'image', 'path' => '@webroot/upload/user/{id}', 'url' => '@web/upload/user/{id}', //'multiple' => true, //'multipleSeparator' => '|', //'nullValue' => '', //'instanceByName' => false, //'generateNewName' => true,//function($file){return uniqid().$file->name.;} //'unlinkOnSave' => true, //'deleteTempFile' => true, //'scenarios' => ['insert', 'update'], //'createThumbsOnSave' => true, //'createThumbsOnRequest' => true, // 'thumbs' => [ // 'thumb' => ['width' => 400, 'height' => 400,'quality' => 90], // 'preview' => ['width' => 200, 'height' => 200], //], //'placeholder' => '@app/modules/user/assets/images/userpic.jpg', //'thumbPath' => '@webroot/upload/user/{id}/thumb', //'thumbUrl' => '@web/upload/user/{id}/thumb', ], [ .... ] ], 'scenarios' => ['insert', 'update'], //'multipleSeparator' => '|', //'nullValue' => '', //'instanceByName' => false, //'generateNewName' => true,//function($file){return uniqid().$file->name.;} //'unlinkOnSave' => true, //'deleteTempFile' => true, //'createThumbsOnSave' => true, //'createThumbsOnRequest' => false, // 'thumbs' => [ // 'thumb' => ['width' => 400, 'height' => 400,'quality' => 90], // 'preview' => ['width' => 200, 'height' => 200], //], ], ]; } }
Example view single file:
<?php $form = ActiveForm::begin(['options' => ['enctype' => 'multipart/form-data']]); ?> <div class="form-group"> <div class="row"> <div class="col-lg-6"> <!-- Original image --> <?= Html::img($model->getUploadUrl('image'), ['class' => 'img-thumbnail']) ?> </div> <div class="col-lg-4"> <!-- Thumb 1 (thumb profile) --> <?= Html::img($model->getThumbUploadUrl('image'), ['class' => 'img-thumbnail']) ?> </div> <div class="col-lg-2"> <!-- Thumb 2 (preview profile) --> <?= Html::img($model->getThumbUploadUrl('image', 'preview'), ['class' => 'img-thumbnail']) ?> </div> </div> </div> <?= $form->field($model, 'image')->fileInput(['accept' => 'image/*']) ?> <div class="form-group"> <?= Html::submitButton('Submit', ['class' => 'btn btn-primary']) ?> </div> <?php ActiveForm::end(); ?>
Example view multiple file:
<?php $form = ActiveForm::begin(['options' => ['enctype' => 'multipart/form-data']]); ?> <?php $imageUrls = $model->getUploadUrl('image'); //$imageUrls = $model->getThumbUploadUrl('image'); //$imageUrls = $model->getThumbUploadUrl('image', 'preview'); foreach ($imageUrls as $imgUrl) { ... } ?> <?php ActiveForm::end(); ?>
if you install https://github.com/kartik-v/yii2-widget-fileinput
$form->field($model, 'image')->widget(FileInput::classname(), [ 'options' => [ 'accept' => 'image/*', 'multiple' => true, 'name' => Html::getInputName($model, 'image').'[]', ], 'pluginOptions' => [ 'initialPreview'=> !$model->image ? [] : $model->createPreview(['attribute' => 'image', 'profile' => 'preview']), 'overwriteInitial'=> !$model->image ? false: true,
Behavior Options
- attributes - The attributes which Hold collection for the attachment
- scenarios - The scenarios in which the behavior will be triggered
- instanceByName - Getting file instance by name, If you use UploadBehavior in
RESTfull
application and you do not need a prefix of the model name, set the propertyinstanceByName = false
, default value isfalse
- path - the base path or path alias to the directory in which to save files.
- url - the base URL or path alias for this file
- generateNewName - Set true or anonymous function takes the old filename and returns a new name, default value is
true
- unlinkOnSave - If
true
current attribute file will be deleted, default value istrue
- unlinkOnDelete - If
true
current attribute file will be deleted after model deletion.
Attention!
It is prefered to use immutable placeholder in url
and path
options, other words try don't use related attributes that can be changed. There's bad practice. For example:
class Track extends ActiveRecord
{
public function getArtist()
{
return $this->hasOne(Artist::className(), [ 'id' => 'id_artist' ]);
}
public function behaviors()
{
return [
[
'class' => UploadBehavior::className(),
'attribute' => 'image',
'scenarios' => ['default'],
'path' => '@webroot/uploads/{artist.slug}',
'url' => '@web/uploads/{artist.slug}',
],
];
}
}
If related model attribute slug
will change, you must change folders' names too, otherwise behavior will works not correctly.
