我创建了我自己的WordPress插件与小部件，我的问题是，当我在我的widgetname_widget. php修改一半的修改不适用.
我的代码：

class Blocs_Home_HS_Widget extends WP_Widget {

    public function __construct() {

        parent::__construct('blocshomehswidget', 'Blocs Home (version mobile)', array('description' => 'Gestion du contenu des blocs de la page d\'accueil version mobile'));
    }

    public function widget($args, $instance) {

        $strReturn = disposition_blocs_home_handheld(array('sport_title' => $instance['sport_title'], 'sport_content' => $instance['sport_content'], 'sante_title' => $instance['sante_title'], 'sante_content' => $instance['sante_content'], 'be_title' => $instance['be_title'], 'be_content' => $instance['be_content'], 'recup_title' => $instance['recup_title'], 'recup_content' => $instance['recup_content']));

        echo $strReturn;
    }

    public function form($instance) {

        $sport_title = isset($instance['sport_title']) ? $instance['sport_title'] : '';
        $sport_content = isset($instance['sport_content']) ? $instance['sport_content'] : '';
        $sante_title = isset($instance['sante_title']) ? $instance['sante_title'] : '';
        $sante_content = isset($instance['sante_content']) ? $instance['sante_content'] : '';
        $be_title = isset($instance['be_title']) ? $instance['be_title'] : '';
        $be_content = isset($instance['be_content']) ? $instance['be_content'] : '';
        $recup_title = isset($instance['recup_title']) ? $instance['recup_title'] : '';
        $recup_content = isset($instance['recup_content']) ? $instance['recup_content'] : '';

当我修改函数widget()、form()和构造函数时，没有问题，我重新加载页面（包含小部件）并应用修改。
但是当我修改我创建的函数（random_pos_handheld()和disposition_blocs_home_handheld()）时，什么都没有...我试图重新加载页面，停用并重新激活插件，重新安装最后的WordPress更新...没有什么。我想我必须强制重新加载widget_init，但我在互联网上没有找到任何东西。
