custom fields (in a custom page) are not saved (wordpress) (complete code on bottom)

I'm writing a plugin to create custom slugs, boxes and text blocks that allow you to save the data in the Wordpress database. For example, a products custom pages, which you can give values.

I've made three files.

On this moment I am hanging on the mediabox.php code.

It does not want to save the values of the boxes and input fields into the database.

I have documented everything in the PHP document so that you might be able to help me a little better :) (Everyone is free to provide feedback :)).

I start my class with a namespace with the class media box. That's included $name (name of the box), $post (to get the postID) and the $output (generates the html)

In the constructor, I give add the $post so it can call itself in a function.

 namespace App\controller\build;

class mediabox
{

    protected $name;
    protected $post;
    protected $output = "";

    /**
     * mediabox constructor.
     * @param $name
     */
    public function __construct($post, $name)
    {
        // In de __construct roepen wij de add_meta_boxes aan, die de boxen dienen aan te maken
        $this->name = $name;
        $this->post = $post;
        add_action('add_meta_boxes', [$this, 'api_add_meta_boxes']);
//Save function
        if (!isset($_POST['api_meta_box_nonce']) || !wp_verify_nonce($_POST['api_meta_box_nonce'], basename(__FILE__))) {
            return;
        }
        // return if autosave
        if (defined('DOING_AUTOSAVE') && DOING_AUTOSAVE) {
            return;
        }
        // Check the user's permissions.
        if (!current_user_can('edit_post', $post)) {


             return;
            }
  update_post_meta($this->post, '_api_UserEnabled', 'aaaaa');
    }

In the mini code above I call an update function that does not work properly.

/**
     * @param $name
     * @return mediabox
     * Hier wordt de factorie functie aangeroepen
     */
    public static function factory($post, $name)
    {
        return new self($post, $name);
    }

In addition, I have created a factory that calls itself.

After this I call the add_meta_boxes

/**
 * @param $name
 */
public function api_add_meta_boxes($name)
{
    // Roept api_meta_box aan
    add_meta_box('api_meta_box', __($name, 'api_example_plugin'), [$this, 'api_build_meta_box'], $this->name, 'normal', 'high');
    wp_nonce_field(basename(__FILE__), 'api_meta_box_nonce');
}

And finally, I make the function to generate the boxes and text fields.

/**
     * @param $post
     * @param $build_name
     * @return $this
     * In deze functie kan een radiobutton worden aangemaakt, hier dient een array aan toegevoegd te worden
     */
    public function build_radio($build_name, $array)
    {
        $current_UserEnabled = get_post_meta($this->post->ID, '_api_UserEnabled', true);
        $this->output .= " 
        <h3>{$build_name} </h3>";
        foreach ($array as $key) {
            $this->output .= " 
            <input type='radio' name='{$build_name}' value = '{$key}'" . checked($current_UserEnabled, $key) . ">{$key}<br>";
            ?>

            </div>
            <?php
            # code...
        }
        return $this;
    }

    /**
     * @param $post
     * @param $build_name
     * @return $this
     */
    public function build_textbox($build_name)
    {
        $current_Username = get_post_meta($this->post->ID, $build_name, true);
        $this->output .= "<h3>{$build_name}</h3><p><input type='text' name='{$build_name}' value='{$current_Username}'/></p>";


        return $this;
    }

    /**
     * @param $post
     * @param $build_name
     * @return $this
     */
    public function build_selectbox($build_name, $userinfo)
    {
        $this->output .= " 
        <h3>{$build_name} </h3>";
        foreach ($userinfo as $myuserinfo) {
            $this->output .= "<p>{$myuserinfo}</p>";
            $this->output .= "<input type=checkbox name='{$build_name}' value='{$myuserinfo}' " . checked((in_array($build_name, $myuserinfo)) ? $myuserinfo : '', $myuserinfo) . ">";
        }
        ?>
        </p>
        <?php
        return $this;
    }

    /**
     * @param $post
     * @return $this
     */
    public function api_build_meta_box($post)
    {

        echo $this->output;
        return $this;
        var_dump($_post);


    }

}

When I call the update_post_meta with a costum value ( update_post_meta($this->post, '_api_UserEnabled', 'aaaaa');) it does not work :/.

you need to use 

update_post_meta($this->post->ID, '_api_UserEnabled', 'aaaaa');

instead of 

update_post_meta($this->post, '_api_UserEnabled', 'aaaaa');
