Display data from from model without any relation in yii2 - yii2

Question

I have two Models 1. Orders 2. Offers. There's no relation between them.
In the view file of Order I want to display the of_name,of_desc from the latest entry of Offer table.
My offer searchModel looks like:
public function search($params)
{
$query = Offers::find()->orderBy(['of_id' => SORT_DESC])->one();;
// add conditions that should always apply here
$dataProvider = new ActiveDataProvider([
'query' => $query,
]);
$this->load($params);
if (!$this->validate()) {
// uncomment the following line if you do not want to return any records when validation fails
// $query->where('0=1');
return $dataProvider;
}
// grid filtering conditions
$query->andFilterWhere([
'of_id' => $this->of_id,
]);
$query->andFilterWhere(['like', 'of_name', $this->of_name])
->andFilterWhere(['like', 'of_description', $this->of_description]);
return $dataProvider;
}
In the controller action of Order I've tried -
public function actionPrintorders($id) {
$model = $this->findModel($id);
$searchModel = new OrdersSearch();
$dataProvider = $searchModel->search(Yii::$app->request->queryParams);
$data = Orders::findOne($id);
$searchModel1 = new OffersSearch();
//$dataProvider1 = $searchModel1->search(Yii::$app->request->queryParams);
$content = $this->renderPartial('_printorder', [
'model' => $model,
'dataProvider' => $dataProvider,
'searchModel' => $searchModel,
'data'=> $data,
'searchModel1' => $searchModel1,
//'dataProvider1' => $dataProvider1,
//'model2' => $model2,
//'period' => $period,
]);
$footer = "<table name='footer' width=\"1000\">
<tr>
<td style='font-size: 18px; padding-bottom: 20px;' align=\"left\"><u>Working Hours : </u></td>
</tr>
<tr>
<td style='font-size: 18px; padding-bottom: 20px;' align=\"left\">9:00am to 9:00pm</td>
</tr>
<tr>
<td style='font-size: 18px; padding-bottom: 20px;' align=\"left\">Friday Morning Closed</td>
<td style='font-size: 18px; padding-bottom: 20px;' align=\"right\">Prop: M.Sinha</td>
</tr>
</table>";
$pdf = new Pdf([
'mode'=> Pdf::MODE_UTF8,
'format'=> Pdf::FORMAT_A4,
'destination'=> Pdf::DEST_BROWSER,
//'destination' => Pdf::DEST_DOWNLOAD,
'cssFile' => '#vendor/kartik-v/yii2-mpdf/assets/kv-mpdf-bootstrap.min.css',
// any css to be embedded if required
'cssInline' => '.kv-heading-1{font-size:18px}',
// set mPDF properties on the fly
'options' => ['title' => 'Print Orderslip'],
//'options' => ['defaultfooterline' => 0,],
// call mPDF methods on the fly
'methods' => [
'SetHeader'=>['Amit Optical'],
'SetFooter'=>[$footer],
],
'content' => $content,
]);
return $pdf->render();
//return $this->render('_printSalarystatement', ['s_period' => $s_period]);
}
And tried to pass value in the order view like -
<h3 style="margin-bottom:0;margin-top:2;margin-left:2;"><strong><p class="text-center"><?php echo $searchModel1['of_name'];?></p></strong></h3>
There's no error but there's no output like this line either. Please tell me how to do it.
Update
I've tried the solution made here Yii2 render two models in one view
But obviously stuck at $key. Not sure how to pass it.
My present controller action looks like below.
public function actionPrintorders($id) {
$model = $this->findModel($id);
$searchModel = new OrdersSearch();
$dataProvider = $searchModel->search(Yii::$app->request->queryParams);
$data = Orders::findOne($id);
$searchModel1 = new OffersSearch();
$modelOffer = Offers::findOne($key);
//$dataProvider1 = $searchModel1->search(Yii::$app->request->queryParams);
$content = $this->renderPartial('_printorder', [
'model' => $model,
'dataProvider' => $dataProvider,
'searchModel' => $searchModel,
'data'=> $data,
'searchModel1' => $searchModel1,
'modelOffer'=>$modelOffer,
//'dataProvider1' => $dataProvider1,
//'model2' => $model2,
//'period' => $period,
]);
$footer = "<table name='footer' width=\"1000\">
<tr>
<td style='font-size: 18px; padding-bottom: 20px;' align=\"left\"><u>Working Hours : </u></td>
</tr>
<tr>
<td style='font-size: 18px; padding-bottom: 20px;' align=\"left\">9:00am to 9:00pm</td>
</tr>
<tr>
<td style='font-size: 18px; padding-bottom: 20px;' align=\"left\">Friday Morning Closed</td>
<td style='font-size: 18px; padding-bottom: 20px;' align=\"right\">Prop: M.Sinha</td>
</tr>
</table>";
$pdf = new Pdf([
'mode'=> Pdf::MODE_UTF8,
'format'=> Pdf::FORMAT_A4,
'destination'=> Pdf::DEST_BROWSER,
//'destination' => Pdf::DEST_DOWNLOAD,
'cssFile' => '#vendor/kartik-v/yii2-mpdf/assets/kv-mpdf-bootstrap.min.css',
// any css to be embedded if required
'cssInline' => '.kv-heading-1{font-size:18px}',
// set mPDF properties on the fly
'options' => ['title' => 'Print Orderslip'],
//'options' => ['defaultfooterline' => 0,],
// call mPDF methods on the fly
'methods' => [
'SetHeader'=>['Amit Optical'],
'SetFooter'=>[$footer],
],
'content' => $content,
]);
return $pdf->render();
}

Answer 1

The error is at beginning of code, that it should be
public function search($params)
{
$query = Offers::find()->orderBy(['of_id' => SORT_DESC]);
without the ->one() at the end of $query var, because ActiveDataProvider needs \yii\db\ActiveQuery object.
