How to delete blog posts?

Question

Yii

What is the post deletion mechanism in Yii2? In the project, the blog is rendered as a separate module. If you delete a post on a local site in the backend, then debage does not fix errors, you have to close the page through the task manager, because the browser freezes, and posts are deleted only in the database.
Tried to add such method to Blog.Controller - doesn't work.

public function actionDelete($id=NULL)
{
    if ($id === NULL)
    {
        Yii::$app->session->setFlash('PostDeletedError');
        Yii::$app->getResponse()->redirect(array('site/index'));
    }
 
    $post = Post::find($id);
 
 
    if ($post === NULL)
    {
        Yii::$app->session->setFlash('PostDeletedError');
        Yii::$app->getResponse()->redirect(array('site/index'));
    }
 
    $post->delete();
 
    Yii::$app->session->setFlash('PostDeleted');
    Yii::$app->getResponse()->redirect(array('site/index'));
}

Answer 1

posts are deleted only in the database

Where else should they go?
Here yii has nothing to do with it.
if you do public function actionDelete($id)
Then yii and so it will throw an error, so the first condition is superfluous, I'm talking about

if ($id === NULL)
    {
        Yii::$app->session->setFlash('PostDeletedError');
        Yii::$app->getResponse()->redirect(array('site/index'));
    }

And in general, you screwed up a lot of superfluous things, the standard crud through gii makes a normal action, you even brought it in the code, all that remains is to add flash:

public function actionDelete($id){
    if (($post = Post::findOne($id)) and $post->delete())
    {
         Yii::$app->session->setFlash('PostDeleted');
    }else{
         Yii::$app->session->setFlash('PostDeleted');
   }
   return $this->redirect(['site/index']);
}

Answer 2

This code is not working

public function actionDelete($id){
    if (($post = Post::findOne($id)) and $post->delete())
    {
         Yii::$app->session->setFlash('PostDeleted');
    }else{
         Yii::$app->session->setFlash('PostDeleted');
   }
   return $this->redirect(['site/index']);
}

Let me explain: if you go to MySQL manager in 'blog' - 'data' and 'delete the selected row', then the post will be deleted.
Should be removed from the site.
If you try to delete a post on the blog page " admin.site.com/blog " or at: " admin.site.com/blog/blog/view?id=4 " then the posts will not be deleted. After clicking in the lower left corner, the line appears: admin.site.com/blog/blog/delete?id=4 and the browser window can only be closed after that through the task manager.
I tried everything, I thought at first: maybe some JS left with an infinite loop? But here's what's interesting. In GoogleChrome, it freezes, and in Microsoft Edge, the post was deleted from the first time, but an error appeared from the second:
Mozzila is the same. If you comment out 'beforeDelete' completely in Blog.php, then the post is deleted.
What is the reason here?
