Im using a Widget to crop and upload images into a server with Yii2.
Yii2 - Cropper
I've implemented the widget in a view, based on the documentation of the Widget, and submited the data to a model wich should save the name of the uploaded file into a new entry in the database. However, it always saves it as Null.
newform.php
<?php
use yii\helpers\Html;
use yii\widgets\ActiveForm;
use common\budyaga\cropper\Widget;
use yii\helpers\Url;
$this->title='Upload New';
?>
<h1><?= Html::encode($this->title) ?></h1>
<?php $form = ActiveForm::begin(); ?>
<?= $form->field($model, 'title') -> textInput();?>
<?= $form->field($model, 'description') -> textInput(); ?>
<?= $form->field($model, 'link') -> textInput(); ?>
<?= $form->field($model, 'image')-> widget(Widget::className(), [
'uploadUrl' => Url::toRoute('/admin/uploadPhoto'),
'width' => 236,
'height' => 234,
'cropAreaWidth' => 500,
'cropAreaHeight' => 500,
'thumbnailWidth' => 236,
'thumbnailHeight' => 234,
]);?>
<div class="form-group">
<?= Html::submitButton('Save', ['class' => 'btn btn-primary']); ?>
</div>
<?php ActiveForm::end(); ?>
Method in controller
public function actionNews(){
$model = new NewsForm();
$model->setScenario('addNew');
if ($model->load(Yii::$app->request->post()) && $model->addNew()) {
return $this->render('newsmanager');
} else {
return $this->render('newform', ['model' => $model]);
}
}
Model
class Newnews extends \yii\db\ActiveRecord{
public static function tableName()
{
return 'news';
}
public function rules()
{
return [
[['visits', 'user_id'], 'integer'],
[['user_id'], 'required'],
[['title', 'image'], 'string', 'max' => 45],
[['description', 'link'], 'string', 'max' => 255],
[['user_id'], 'exist', 'skipOnError' => true, 'targetClass' => User::className(), 'targetAttribute' => ['user_id' => 'id']],
];
}
public function attributeLabels()
{
return [
'idnew' => 'Idnew',
'title' => 'Title',
'description' => 'Description',
'image' => 'Image',
'visits' => 'Visits',
'user_id' => 'User_ID',
'link' => 'Link',
'dateu' => 'Dateu'
];
}
}
NewsForm.php
class NewsForm extends Model
{
public $image;
public $title;
public $description;
public $link;
public function rules()
{
return [
[['title','description','link'],'required'],
['image','safe', 'on'=>'addNew']
];
}
public function addNew(){
if($this->validate()){
$newnew=new Newnew();
$newnew->title=$this->title;
$newnew->description=$this->description;
$newnew->link=$this->link;
$newnew->image;
$newnew->user_id=Yii::$app->getUser()->getId();
$newnew->visits=0;
$newnew->dateu=date("Y-m-d H:i:s");
return $newnew->save();
}
}
}
When I try to save the data, I get a Null in image. I dont know how to get the data from the wiget to extract the name of the image in the Model. How do I acces this data?
add in NewsForm :
/**
* @var UploadedFile
*/
public $imageFile;
and in validation rules:
[['imageFile'], 'file', 'mimeTypes' => 'image/jpeg, image/png', 'maxSize' => 5000000],
in addNew() function:
$this->imageFile = UploadedFile::getInstance($this, 'imageFile');
$file = $this->imageFile;
$fname = $file->baseName
$fext = $file->extension
//etc...
//then validate and save file and model as you want.
in view form:
<?= $form->field($model, 'imageFile ')-> widget(Widget::className(), [
//config...
]);
