Yii2 tools for upload file
The preferred way to install this extension is through composer.
Either run
php composer.phar require mdmsoft/yii2-upload-file "~1.2"
for dev-master
php composer.phar require mdmsoft/yii2-upload-file "dev-master"
or add
"mdmsoft/yii2-upload-file": "~1.2"
to the require section of your composer.json file.
Once the extension is installed. Prepare required table by execute yii migrate.
yii migrate --migrationPath=@mdm/upload/migrations
if wantn't use db migration. you can create required table manually.
CREATE TABLE uploaded_file (
"id" INT NOT NULL AUTO_INCREMENT,
"name" VARCHAR(64),
"filename" VARCHAR(256),
"size" INT,
"type" VARCHAR(32),
PRIMARY KEY (id)
);Modify your application configuration as follows:
return [
...
'controllerMap' => [
'file' => 'mdm\\upload\\FileController', // use to show or download file
],
];Then simply modify your Model class:
public function behaviors()
{
return [
...
[
'class' => 'mdm\upload\UploadBehavior',
'attribute' => 'file', // required, use to receive input file
'savedAttribute' => 'file_id', // optional, use to link model with saved file.
'uploadPath' => '@common/upload', // saved directory. default to '@runtime/upload'
'autoSave' => true, // when true then uploaded file will be save before ActiveRecord::save()
'autoDelete' => true, // when true then uploaded file will deleted before ActiveRecord::delete()
],
];
}You dont need add extra attribute file to model class. In controller
public function actionCreate()
{
if($model->load(Yii::$app->request->post()) && $model->save()){
...
}
...
}If you set mdm\upload\UploadBehavior::$autoSave to false you must call saveUploadedFile().
public function actionCreate()
{
if($model->load(Yii::$app->request->post()) && $model->validate()){
if($model->saveUploadedFile() !== false){
$model->save(false);
....
}
...
}
...
}In view file
// in create or update view
<?= $form->field($model,'file')->fileInput(); ?>
// in view
<?= Html::img(['/file','id'=>$model->file_id]) ?>
<!-- assume the uploaded file is image ->Instead of using as behavior, you can also directly save file using FileModel.
public function actionCreate()
{
...
if($model->load(Yii::$app->request->post()) && $model->validate()){
$file = UploadedFile::getInstance($model,'file');
if($fileModel = FileModel::saveAs($file,'@common/upload')){
$model->fil_id = $fileModel->id;
$model->save();
....
}
...
}
}But, you need to add attribute file to Model.
class MyModel extend ...
{
public $file; // add this to your model class- See my blog
