Hi guys, I’m face a problem when I try do an upload and save in DB. The upload works fine but save in DB not.
I think it’s occur coz I put a "hash concatened with image name.
I followed the doc, but the full process do not work. I don’t know where is my mistake.
Follow my codes.
Model
public function upload()
{
if ($this->validate()) {
FileHelper::createDirectory('uploads/img/banners/');
$this->url_imagem->saveAs('uploads/img/banners/' . $this->url_imagem->baseName . '-' . date('YmdHis') . '.' . $this->url_imagem->extension);
return true;
} else {
return false;
}
}
Conreoller
public function actionCreate()
{
$model = new Banners();
if ($model->load(Yii::$app->request->post())) {
// && $model->save()
// return $this->redirect(['view', 'id' => $model->id]);
$model->url_imagem = UploadedFile::getInstance($model, 'url_imagem');
//$model->url_imagem = UploadedFile::getInstanceByName('url_imagem');
var_dump($model->url_imagem);
$model->upload();
} else {
return $this->render('create', [
'model' => $model,
]);
}
}
in database your storing image or Only file name if your storing file name then remove hash from the file name and rename it . or if you don’t want to do it then store image as it but while storing in data base rename it and save it .
After that when you download that than check the image name
for example : if your image name is #imagename you store in database as imagename, while downloading use strreplace(#imagename , #) and match with database name and download it.
I think it may work. I do same thing when i was downloading or uploading the image . I do not store image in database i only store file path , image name and mime type in data base.
So , i think it will help you.
