foreach ($model->imageFiles as $file) {
$imageName = Yii::$app->security->generateRandomString();
$model->added_date = date('Y-m-d');
$model->emp_id = $id;

</div>
</div>
</div>

but i am getting above error. I cannot find the solution for this.

Answer 1

first, in model you must have 2 variable that will save the images and the name of it.
`
* #property string $image_name
*/
class Gallery extends \yii\db\ActiveRecord
{
**public $fileImage=[];**
public static function tableName(){
`
in this case I use $image_name that is one of my model column, and $fileImage, $fileImage is an array that will be used to upload the image,
:)
then in controller
$model = new Gallery(); // this variable is only used to check if everything is valid
if ($model->load(Yii::$app->request->post())) {
$model->fileImage = UploadedFile::getInstances($model,'fileImage');
$a=0;
foreach ($model->fileImage as $file) {
$a++;
$model1 = new Gallery();
$file->saveAs("images/test".$a.".".$file->extension);
$model1->image_url="images/test.".$a.".".$file->extension;
$model1->image_name = "".$a;
$model1->save();
}
return $this->redirect(['index']);
} else {
return $this->render('create', [
'model' => $model,
]);
}
I think thats all. . .

Answer 2

You can use
$sql = 'INSERT INTO `table`(`id`, `col1`, `col2`, `path`) VALUES (Null,"'.($model2->col1).'","'.($model2->col2).'","'.($model2->path).'")';
$command = \Yii::$app->db->createCommand($sql);
$command->execute();
instead of $model->save();
I made an example,
so the whole code in controller would be:
public function actionCreate()
{
$model = new Planet();
if ($model->load(Yii::$app->request->post()) ) {
$model->file = UploadedFile::getInstances($model, 'file');
foreach ($model->file as $file) {
$model2 = new Planet();
$model2->load(Yii::$app->request->post());
$model2->path='uploads/' . $file;
$sql = 'INSERT INTO `planet`(`id`, `name`, `s_id`, `path`) VALUES (Null,"'.($model2->name).'","'.($model2->s_id).'","'.($model2->path).'")';
$command = \Yii::$app->db->createCommand($sql);
$command->execute();
$file->saveAs('uploads/' . $file->baseName . '.' . $file->extension);
}
return $this->render('view', [
'model' => $model,
]);
} else {
return $this->render('create', [
'model' => $model,
]);
}
}
It works for me.
edit: also you can use $model2->save(false); It worked in my case.

Answer 3

Call $model->save()
before
$model->file->saveAs();
I was having the exact same problem

Answer 4

*I think you forget to create uploads and emp folder or maybe you use wrong folder name, please check your folder name...
*If you want to save the name of that file, you should use different variable (two variable) that will be used to save the images and the name of that images,
