Jestem nowicjuszem w programowaniu i próbuję stworzyć stronę. Kiedy kliknę przycisk Gutemberg, wygeneruje stronę postu z tekstem i obrazem. Problem polega na tym, że strona tworzona jest przy każdym przeładowaniu strony administracyjnej, a nie tylko po przesłaniu przycisku. Dodałem to, ale nadal nie działa. W bazie danych mam utworzonych wiele postów. Co więcej, tekst na mojej opublikowanej stronie nie jest napisany:

if (isset($_POST['submit-gutenberg'])) { $post_id = $this->create_post();

public function woosterPartnerPluginSectionSetup()
    {
        // Add a new section to a settings page.
        add_settings_section('partner_badges_section2', __('Choississez votre constructeur de page', 'wooster-partner'), array($this, 'woosterPartnerPluginSection'), 'wooster_url', array());
    }
