PHP edit and save posts, delete posts - release v.04 on GitHub

For an Admin dashboard is more relevant to see just the titles (not entire content as in normal view) and have edit / delete buttons :

1. Admin dashboard for editing posts

- in the "render()" method of the class Blog, if the admin is logged, Edit button is displayed otherwise normal listing of posts
- new path /edit/{slug} added to route.xml as a result of the above

2. Edit posts and save them to database

- the edit post page should look exactly like the new post entry just that it should be populated with the values from DB. So I added the file "edit_post_entry.php" under templates.
Inside I added value=<?php echo '"'.$author.'"'; ?> (same for the title and category).
- issue:  I do not want to  take the file edit_post_entry.php and include it directly into the main template, I want first to process it (interpret ) with the local variables  replacing the actual "value=" in the HTML form.
The post "Read echo'ed output from another PHP file" http://stackoverflow.com/questions/631388/read-echoed-output-from-another-php-file showed me the way:

        ob_start(); // begin collecting output
        include 'myfile.php';
        $result = ob_get_clean(); // retrieve output from myfile.php, stop buffering
        //$result will then contain the text.

- as you could see the slug is used to identify  the post.Only for update I am using the post Id as unique identifier and the new slug is saved in database if the title of the blog is changed.

I will put in the form (edit_post_entry.php) a hidden field to store the post Id taken from database which will be used in the SQL update statement:

        $new_slug=SlugGenerator::slugify($Title);
        $stmt = $this->db->prepare("UPDATE blogposts SET Category=:field1, Author=:field2, ActualPost=:field3,title=:field4,slug=:field5 WHERE Id=:field_id;");
        $stmt->bindParam(':field_id',$PostID, PDO::PARAM_INT);
        $stmt->bindParam(':field1', $Category);
        $stmt->bindParam(':field2', $Author);
        $stmt->bindParam(':field3', $Text);
        $stmt->bindParam(':field4', $Title);
        $stmt->bindParam(':field5', $new_slug);
   

    $stmt->execute();

3. Delete posts   

First I get the post using  "getPost($post_slug)" and from the output the post Id is read and the delete is applied to that Id.

The code is available in my first release on GitHub, v0.4:  https://github.com/cristianpana86/myFrontController/releases/tag/v0.4
