Yii2: Images stored in different tables - file-upload

Question

Here my controller:
$model = new VehicleType();
if ($model->load(Yii::$app->request->post())) {
if($model->validate()){
$model->save();
$id = $model->id;
$model->file = UploadedFile::getInstance($model, 'file');
if($model->file){
$id = $model->id;
$imageName = "vehicletype_".$id.'_'.getdate()[0];
$model->file->saveAs('uploads/'.$imageName.'.'.$model->file->extension);
$station = VehicleType::findOne($id);
$station->image = '#web/uploads/'.$imageName.'.'.$model->file->extension;
$station->save();
}
return $this->redirect(['vehicletype/index']);
}
} else {
return $this->renderAjax('create', [
'model' => $model,
]);
}
}
My view:
<div class="row">
<div class="col-lg-5">
<?php $form = ActiveForm::begin(['id' => 'station-form', 'options' => ['enctype' => 'multipart/form-data']]); ?>
<?= $form->field($model, 'name') ?>
<?= $form->field($model, 'description')->textarea() ?>
<?= $form->field($model, 'file')->fileInput() ?>
<div class="form-group">
<?= Html::submitButton('Submit', ['class' => 'btn btn-primary', 'name' => 'contact-button']) ?>
</div>
<?php ActiveForm::end(); ?>
</div>
My model:
public function rules()
{
return [
[['description'], 'string'],
[['record_status'], 'integer'],
[['name', 'image'], 'string', 'max' => 255]
];
}
/**
* #inheritdoc
*/
public function attributeLabels()
{
return [
'id' => 'ID',
'name' => 'Name',
'description' => 'Description',
'image' => 'Image',
'record_status' => 'Record Status',
];
}
/**
* #return \yii\db\ActiveQuery
*/
public function getVehicles()
{
return $this->hasMany(Vehicles::className(), ['vehicle_type_id' => 'id']);
}
}
With this I can upload only one picture/post, I want one post to have multiple pictures, so I create a new table call 'Image' to stored my pictures and have a one-to-many relationship.
But I run into a problem, how can I add data to 2 tables from just 1 form
I'm using Yii2 basic template
Thanks

Answer 1

Step 1
First create two variables in your vehicletype model.
public $uploadedImages;
public $imageforNewtable = array();
Step 2
Make sure to mention this imageforNewtable variable in your model rule.
[['imageforNewtable'], 'image', 'extensions' => 'png, jpg, JPEG'],
Step 3
In your form:
<?php $form = ActiveForm::begin(['id' => 'station-form', 'options' => ['enctype' => 'multipart/form-data']]); ?>
<?= $form->field($model, 'imageforNewtable[]')->fileInput(['accept' => 'image/*']); ?>
Step 4
In Your Controller:
$model->uploadedImages = UploadedFile::getInstances($model,'imageforNewtable');
// Make sure to put "Instances" (plural of Instance) for uploading multiple images
$model->imageforNewtable = array(); // To avoid blank entries as we have entries in $_FILES not in $_POST.
foreach ($model->uploadedImages as $singleImage)
{
$model->imageforNewtable[] = time() . '_' . $singleImage->name;
}
Now bulk insert data in Images table :
$bulkInsertforimages = array(); //defined benchInsert array for images
$columnsArray = ['blog_id', 'image']; //Column names in which bulk insert will take place.
if ($model->imageforNewtable != '') {
foreach ($model->imageforNewtable as $singleData) {
$bulkInsertforimages[] = [
'blog_id' => $model->id,
'image' => $singleData,
];
}
}
if (count($bulkInsertforimages) > 0) {
$command = \Yii::$app->db->createCommand();
$command->batchInsert('YOUR_IMAGE_TABLE', $columnsArray, $bulkInsertforimages)->execute();
}
