Yii2 Call to a member function getImageUrl() on a non-object - php

Question

I have a GridView where it displays data and one of them is an image. Here is my code in my GridView:
echo GridView::widget([
'dataProvider' => $dataProvider,
//'filterModel' => $searchModel,
'columns' => [
['class' => 'yii\grid\SerialColumn'],
'fullName',
[
'header' => '<a style="cursor: pointer;">Attachment</a>',
'format' => 'html',
'value' => function ($data) {
return Html::img($data->getImageUrl(), ['class' => 'reim-attach']);
},
],
'receipt_company',
'description',
'date',
'amount',
[
'attribute' => 'chargeable',
'value' => function ($model) {
return $model['chargeable'] ? 'Chargeable' : 'Non-chargeable';
},
],
'GST_amount',
'date_noted',
[
'attribute' => 'status',
'label' => 'Status',
'content' => function ($model, $key, $index, $column) {
if ($model['status'] == "Pending") {
return Html::button('Pending', ['class' => 'status-pending']);
} elseif ($model['status'] == "Draft") {
return Html::button('Draft', ['class' => 'status-pending']);
} elseif ($model['status'] == "Approved") {
return Html::button('Approved', ['class' => 'status-approved']);
} else {
return Html::button('Rejected', ['class' => 'status-rejected']);
}
}
],
[
'label' => 'Action',
'content' => function ($model, $key, $index, $column) {
if($model['status'] == "Pending") {
return Html::button('<span class="glyphicon glyphicon-eye-open"></span>', ['value' => Url::to(['view']).'&id=' . (string)$model['_id'], 'class' => 'btn btn-warning btn-view btn-responsive','id' => 'modalButton2'])
.'&nbsp'
.Html::button('<i class="fa fa-check-circle-o"></i> Approve', ['value' => $model['_id'], 'class' => 'btn btn-info btn-responsive', 'onclick'=>'approve(value)', 'data-toggle'=>'tooltip','title'=>'Approve', 'data' => [ 'confirm' => 'Are you sure you want to approve this reimbursement?', 'method' => 'post', ]])
.'&nbsp'
.Html::button('<i class="fa fa-ban"></i> Reject', ['value' => $model['_id'], 'class' => 'btn btn-danger btn-responsive', 'onclick'=>'reject(value)', 'data-toggle'=>'tooltip','title'=>'Reject', 'data' => [ 'confirm' => 'Are you sure you want to reject this reimbursement?', 'method' => 'post', ]]);
} elseif($model['status'] == "Draft") {
return Html::button('<span class="glyphicon glyphicon-eye-open"></span>', ['value' => Url::to(['view']).'&id=' . (string)$model['_id'], 'class' => 'btn btn-warning btn-view btn-responsive','id' => 'modalButton2'])
.'&nbsp'
.Html::button('<i class="fa fa-check-circle-o"></i> Save Reimbursement', ['value' => $model['_id'], 'class' => 'btn btn-info btn-responsive', 'onclick'=>'saveReimbursement(value)', 'data-toggle'=>'tooltip','title'=>'Save Reimbursement', 'data' => [ 'confirm' => 'Are you sure you want to save this reimbursement?', 'method' => 'post', ]]);
} else {
return Html::button('<span class="glyphicon glyphicon-eye-open"></span>', ['value' => Url::to(['view']).'&id=' . (string)$model['_id'], 'class' => 'btn btn-warning btn-view btn-responsive','id' => 'modalButton2'])
.'&nbsp'
.Html::button('<i class="fa fa-check-circle-o"></i> Approve', ['value' => $model['_id'], 'class' => 'btn btn-default btn-responsive disable', 'onclick'=>'approve(value)', 'data-toggle'=>'tooltip','title'=>'Approve', 'data' => [ 'confirm' => 'Are you sure you want to approve this reimbursement?', 'method' => 'post', ]])
.'&nbsp'
.Html::button('<i class="fa fa-ban"></i> Reject', ['value' => $model['_id'], 'class' => 'btn btn-default btn-responsive disable', 'onclick'=>'reject(value)', 'data-toggle'=>'tooltip','title'=>'Reject', 'data' => [ 'confirm' => 'Are you sure you want to reject this reimbursement?', 'method' => 'post', ]]);
}
}
]
],
]);
I get the following error on the line return Html::img($data->getImageUrl(), ['class' => 'reim-attach']):
Call to a member function getImageUrl() on a non-object
Here's a snippet of my controller:
$model = new Reimbursement();
$reimbursementQuery = new Query;
$reimbursementQuery->select([])->from('reimbursement')->andwhere(['company_id' => new \MongoId($session['company_id'])]);
if (isset(Yii::$app->request->getBodyParams()['period'])) {
if(Yii::$app->request->getBodyParams()['period'] != '') {
echo Yii::$app->request->getBodyParams()['period'];
$refreshData = true;
$selectedPeriodID = Yii::$app->request->getBodyParams()['period'];
$selectedPeriod = Periods::find()->where(['_id' => $selectedPeriodID])->one();
$reimbursementQuery->andWhere(['date_reimbursed' => array('$gte' => date('Y/m/d', strtotime($selectedPeriod->p_start)), '$lte' => date('Y/m/d', strtotime($selectedPeriod->p_end))) ]);
}
}
$reimbursements = $reimbursementQuery->all();
$dataProvider = new ArrayDataProvider([
'allModels' => $reimbursements,
]);
if($refreshData) {
return $this->renderPartial('_reports', [
'dataProvider' => $dataProvider,
]);
}
$dataProvider->pagination->pageSize = 10;
return $this->render('reports', [
'searchModel' => $searchModel,
'dataProvider' => $dataProvider,
'model' => $model,
'rModel' => $rModel,
'employees' => $employees,
'contacts' => $contacts,
'periods' => $periods,
]); exit;
Here's also my model:
public function getImageUrl()
{
return Url::to('#web/' . $this->attachment, true);
}
Hope somebody could point out where I missed and how to get rid of the error.

Answer 1

Its happen because you access none data in database or you didnt specify your function. . .
[ 'header' => '<a style="cursor: pointer;">Attachment</a>', 'format' => 'html','value' => function ($data) {
$attachment = YourModel::find($model->yourId)->one()->attachment;
return Html::img(Url::to('#web/' . $attachment, true), ['class' => 'reim-attach']);
},
],
