yii2 setting max id in controller action as default - php

Question

I have a view which list multiple photo galleries.
so from the menu when I try to access the gallery view the action is
site/gallery
Now in my controller action I am trying like this to show the latest photo-gallery added as first.
This is my code in controller:
public function actionGallery($id = null)
{
//$this->layout = "#app/themes/frontend/main";
$activities = Activities::find()
->where(['status' => 1])
->orderBy(['id' => SORT_DESC])
->all();
$model = Activities::find()->where(['id' => $id])->one();
if ($id == null) {
$gallery = Gallery::find()
->where(
[
'status' => 'active',
'activity_name' => max(['id'])
]
)->all();
} else {
$gallery = Gallery::find()
->where(
['status' => 'active', 'activity_name' => $id]
)->all();
}
return $this->render(
'gallery',
[
'gallery' => $gallery,
'activities' => $activities,
'model' => $model
]
);
}
I also tried like:
$gallery = Gallery::find()->where(
[
'status' => 'active',
'activity_name' => max(['activity_name'])
]
)->all();
the code for view:
<?php
$this->title = 'gallery';
?>
<div class="container">
<div class="col-lg-2 col-md-2 col-sm-12 col-xs-12" style='background-color:#fafafa'>
<h3>Activities</h3>
<?php
foreach ($activities as $activity) {
?>
<!-- <a href="<?php // Yii::getAlias('#web');?>/site/gallery?activity_name=<?php //$Categories['id'];?>"> -->
<a href="<?php Yii::getAlias('#web');?>/site/gallery/?id=<?php echo $activity['id']; ?>">
<br><h5 class="text-center"><?php echo $activity['activity_name']; ?></h5>
</a>
<?php
}
?>
</div>
<div class="col-lg-10 col-md-10 col-sm-12 col-xs-12">
<header class="section-header">
<div>
<h3 class="text-center">
<?php echo $model['activity_name'] ?>
</h3>
<h5 class="text-center">
<?php echo $model['activity_description'] ?>
</h5>
<br>
</div>
</header>
<div id="grid-container" class="cbp-l-grid-projects">
<ul>
<?php foreach ($gallery as $galleries) {?>
<div class="cbp-item" style="width:320px;">
<a href="<?php echo Yii::getAlias('#web'); ?>/web/gallery/<?php echo $galleries['id']; ?>/<?php echo $galleries['image']; ?>" data-lightbox="portfolio" data-title="<?php echo $galleries['title']; ?>" title="Preview" class="cbp-lightbox">
<picture>
<source srcset ="<?php echo Yii::getAlias('#web'); ?>/web/gallery/<?php echo $galleries['id']; ?>/<?php echo basename($galleries['image_thumb'], '.jpg') . '.webp'; ?>" type="image/webp">
<source srcset ="<?php echo Yii::getAlias('#web'); ?>/web/gallery/<?php echo $galleries['id']; ?>/<?php echo $galleries['image_thumb']; ?>" type="image/jpeg">
<img src="<?php echo Yii::getAlias('#web'); ?>/web/gallery/<?php echo $galleries['id']; ?>/<?php echo $galleries['image_thumb']; ?>" style ="width:100%;" class="img-fluid" alt="">
</picture>
</a>
</div>
<?php
}
?>
</ul>
</div>
</div>
</div>

I think I have resolved it using the below code.
public function actionGallery($id=null) {
//$this->layout = "#app/themes/frontend/main";
$activities = Activities::find()->where(['status' => 1])->orderBy(['id'=>SORT_DESC])->all();
$model = Activities::find()->where(['id' => $id])->one();
$latestActivity = Activities::find()->max('id');
if($id==null){
$gallery = Gallery::find()->where(['status' => 'active','activity_name'=>$latestActivity])->all();
}else{
$gallery = Gallery::find()->where(['status' => 'active','activity_name'=>$id])->all();
}
return $this->render('gallery', ['gallery' => $gallery,'activities'=>$activities,'model'=>$model]);
}
