So I am working with Yii2 and am fairly new to it. I am using Kartik File upload and have attempted to convert the code for multiple files. but it only saves the first file.
I have removed the validation as this was also failing but will add back in once I know all else is working.
Model:
/**
* Process upload of image
*
* @return mixed the uploaded image instance
*/
public function uploadImage() {
// get the uploaded file instance. for multiple file uploads
// the following data will return an array (you may need to use
// getInstances method)
$image = UploadedFile::getInstances($this, 'image');
foreach ($image as $images) {
// if no image was uploaded abort the upload
if (empty($images)) {
return false;
}
// store the source file name
$this->image_src_filename = $images->name;
$extvar = (explode(".", $images->name));
$ext = end($extvar);
// generate a unique file name
$this->image_web_filename = Yii::$app->security->generateRandomString().".{$ext}";
// the uploaded image instance
return $images;
} }
Controller:
/**
* Creates a new PhotoPhotos model.
* If creation is successful, the browser will be redirected to the 'view' page.
* @return mixed
*/
public function actionCreate()
{
$model = new PhotoPhotos();
if ($model->load(Yii::$app->request->post())) {
// process uploaded image file instance
$images = $model->uploadImage();
if ($model->save(false)) {
// upload only if valid uploaded file instance found
if ($images !== false) {
$path = $model->getImageFile();
$images->saveAs($path);
}
return $this->redirect(['view', 'id' => $model->ID]);
} else {
//error in saving
}
}
return $this->render('create', [
'model' => $model,
]);
}
View:
//uncomment for multiple file upload
echo $form->field($model, 'image[]')->widget(FileInput::classname(), [
'options'=>['accept'=>'image/*', 'multiple'=>true],
]);
