Upload photo widget for Yii2.
The preferred way to install this extension is through composer.
Either run
php composer.phar require --prefer-dist tigrov/yii2-photo-widget
or add
"tigrov/yii2-photo-widget": "~1.0"
to the require section of your composer.json file.
It is better to use the extension with yii2-upload-behavior
Once the extension is installed, you can use it as follow:
Create a model with a photo attribute
class Model extends \yii\db\ActiveRecord
{
/**
* @inheritdoc
*/
public function behaviors()
{
return [
'upload' => [
'class' => '\tigrov\uploadBehavior\UploadBehavior',
'path' => '@runtime/upload',
'attributes' => ['photo'],
// 'saveCallback' => ['\tigrov\photoWidget\PhotoWidgetHelper', 'crop'],
// or if you need to crop and resize
'saveCallback' => function ($model, $attribute, $file, $filename) {
$width = 200;
$height = 200;
\tigrov\photoWidget\PhotoWidgetHelper::crop($model, $attribute, $file, $filename, $width, $height);
}
],
];
}
/**
* @inheritdoc
*/
public function rules()
{
return [
[['photo'], 'file', 'skipOnEmpty' => false, 'extensions' => 'png,jpg,jpeg'],
];
}
}Create an action in a controller
class FormController extends \yii\web\Controller
{
public function actionUpload()
{
$model = new Model();
if ($model->load(\Yii::$app->request->post()) && $model->save()) {
\Yii::$app->session->setFlash('success', 'Model is saved.');
return $this->refresh();
}
return $this->render('form', [
'model' => $model,
]);
}
}Create a form with the file attribute
<?php $form = ActiveForm::begin(); ?>
<?= $form->field($model, 'photo')->widget('\tigrov\photoWidget\PhotoWidget') ?>
<?= Html::submitButton('Submit') ?>
<?php $form::end(); ?>
After submitting the photo it will be saved to specified path.
