This package is the set of two similar behaviors. The first one allows you to keep the uploaded file as-is. And the second one allows you to generate set of thumbnails for the uploaded image. Behaviors could be attached multiple times for different attributes.
The preferred way to install this extension is through composer.
Either run
php composer.phar require --prefer-dist yii-dream-team/yii2-upload-behavior "*"
or add
"yii-dream-team/yii2-upload-behavior": "*"
to the require section of your composer.json.
This behavior allow you to add file uploading logic with ActiveRecord behavior.
Attach the behavior to your model class:
public function behaviors()
{
return [
[
'class' => '\yiidreamteam\upload\FileUploadBehavior',
'attribute' => 'fileUpload',
'filePath' => '@webroot/uploads/[[pk]].[[extension]]',
'fileUrl' => '/uploads/[[pk]].[[extension]]',
],
];
}
You can use Yii path aliases
like @app, @webroot, @web in your path template configuration.
You can also use additional placeholders in path templates.
Placeholder [[foobar]] will be replaced with appropriate placeholder value.
Possible path/url placeholders:
[[model]]- model class name[[pk]]- value of the primary key[[id]]- the same as[[pk]][[attribute_name]]- attribute value, for example[[attribute_ownerId]][[id_path]]- id subdirectories structure (if model primary key is12345, placeholder value will be1/2/3/4/5/0/0/0/0/0[[basename]]- original filename with extension[[filename]]- original filename without extension[[extension]]- original extension
Add validation rule:
public function rules()
{
return [
['fileUpload', 'file'],
];
}
Setup proper form enctype:
$form = \yii\bootstrap\ActiveForm::begin([
'enableClientValidation' => false,
'options' => [
'enctype' => 'multipart/form-data',
],
]);
File should be uploading fine.
You can get uploaded file url using model call:
echo $model->getUploadedFileUrl('fileUpload');
Image upload behavior extends file upload behavior with image thumbnails generation. You can configure set of different thumbnail profiles to generate.
Attach the behavior to your model class:
public function behaviors()
{
return [
[
'class' => '\yiidreamteam\upload\ImageUploadBehavior',
'attribute' => 'imageUpload',
'thumbs' => [
'thumb' => ['width' => 400, 'height' => 300],
],
'filePath' => '@webroot/images/[[pk]].[[extension]]',
'fileUrl' => '/images/[[pk]].[[extension]]',
'thumbPath' => '@webroot/images/[[profile]]_[[pk]].[[extension]]',
'thumbUrl' => '/images/[[profile]]_[[pk]].[[extension]]',
],
];
}

Add validation rule:
public function rules()
{
return [
['imageUpload', 'file', 'extensions' => 'jpeg, gif, png'],
];
}

$form = \yii\bootstrap\ActiveForm::begin([
'enableClientValidation' => false,
'options' => [
'enctype' => 'multipart/form-data',
],
]);
File should be uploading fine.
You can get uploaded image url using model call:
echo $model->getImageFileUrl('imageUpload');
You can specify default image for models without uploaded image:
echo $model->getImageFileUrl('imageUpload', '/images/empty.jpg');
You can also get generated thumbnail image url:
echo $model->getThumbFileUrl('imageUpload', 'thumb');
You can specify default thumbnail image for models without uploaded image:
echo $model->getThumbFileUrl('imageUpload', 'thumb', '/images/thumb_empty.jpg');
