Yii2 - How to upload & store Images in Database - php

Question

I am using yii2. I am trying to select a file and then want to save it to my database table. I am using core PHP for it. Below is my code
<form action = <?=\yii\helpers\Url::toRoute(['meteracceptanceheader/import'])?> method ="post"
enctype="multipart/form-data">
.
.
.
.
.
.
.
<div class="row">
<div class="col-md-2">
Upload-Image
<input type="file" name="file"/>
<br />
<input type="submit" class="btn btn-primary pull-left" />
</div>
</div>
</form>
Controller
public function actionImport()
{
.
.
. // my other code
$file = $_FILES['file'];
$fileName = $_FILES['file']['name'];
$fileExt = explode('.',$fileName);
print_r($file);
die();
.
.
.
.
return $this->render('excel_finish', ['records_saved' => $ok_count,'status_arr'=>$status_arr]);
}
Database Table
In the above table, id is auto-increment accpt_id is the model id which I already have and file_path is the name of the file which should be saved like 123.jpg.
The file should be saved into a folder uploads/meter_acceptance/ and append with the file name.
Note:
I have already know how to upload images via the active form but here I want to do it in a traditional way.
Any help would be highly appreciated.

Answer 1

your controller should be like this
public function actionUpload(){
$model = new Images();
$uploadPath = Yii::getAlias('#root') .'/uploads/';
if (isset($_FILES['image'])) {
$file = \yii\web\UploadedFile::getInstanceByName('image');
$original_name = $file->baseName;
$newFileName = \Yii::$app->security
->generateRandomString().'.'.$file->extension;
// you can write save code here before uploading.
if ($file->saveAs($uploadPath . '/' . $newFileName)) {
$model->image = $newFileName;
$model->original_name = $original_name;
if($model->save(false)){
echo \yii\helpers\Json::encode($file);
}
else{
echo \yii\helpers\Json::encode($model->getErrors());
}
}
}
else {
return $this->render('upload', [
'model' => $model,
]);
}
return false;
}
