I want to upload the image and i want to save the image name in database and move the image to the folder..
But now i can't save any thing.
After uploading the file and submit the form the following error will be displayed
Error (#2)
An internal server error occurred.
My codes are below
In Views:
<div class="row">
<div class="col-lg-5">
<?php $form = ActiveForm::begin(['options' => ['enctype' => 'multipart/form-data']]) ?>
<?php echo $form->field($model, 'varImage')->fileInput() ?>
<div class="form-group">

In Models:
class Usertype extends \yii\db\ActiveRecord
{
public function rules()

return [
[['varImage'], 'safe'],
[['varImage'], 'file', 'extensions'=>'jpg, gif, png'],
];
}
public function attributeLabels()
{
return [
'varImage' => 'Image',
];
}
}
In Controller:
$model = new Usertype();
if ($model->load(Yii::$app->request->post()) )
{
$image = UploadedFile::getInstance($model, 'varImage');
$path = Yii::$app->params['uploadPath'] . $model->varImage;
if($model->save())

$image->saveAs($path);
Yii::$app->getSession()->setFlash('error', 'User type inserted successfully');
return Yii::$app->getResponse()->redirect('/yii2/site/usertype');
}
}
I can't know what error in this code
Kindly help me to fix this.

Answer 1

I think your view and model code is OK.
Try this. This is your controller code. It has worked for me.
if ($model->load(Yii::$app->request->post()) && $model->save()) {
$image = UploadedFile::getInstance($model, 'varImage');
if(!empty($image)){
$image->saveAs('uploads/' . $image->baseName . '.' . $image->extension);
$model->your_database_field_name = $image->baseName . '.' . $image->extension;
$model->save();
}
return $this->redirect(['view', 'id' => $model->id]);
}

In controller:
$fileupload = UploadedFile::getInstance($model, 'image');
if(!empty($fileupload)){
$fileupload->saveAs('uploads/' . $fileupload->baseName . '.' . $fileupload->extension);
$model->image = $fileupload->baseName . '.' . $fileupload->extension;
$model->save();
}
In views:
<?php $form = ActiveForm::begin(['options' => ['enctype' => 'multipart/form-data']]); ?>
<?= $form->field($model, 'image')->fileInput()->label('Upload Photo') ?>
In models:
['image','safe']
