我写了第一节函数课。php，我想用它来创建多个选项卡，只需在我的模板文件上进行简单的调用。当我直接在函数中创建新实例时。php对于该实例来说一切都很好。但当我通过函数外的助手函数调用类时。php，所有操作挂钩都不会生效。有什么建议可以做到这一点吗？

当做

class EasyTabs {

private static $instance;

public static function get_instance() {

    if ( !self::$instance instanceof self )
        self::$instance = new self;
    return self::$instance;

}

public function container_id() {
    $id = rand(1000,9999);
    return $id;
}

public function get_the_tabs() {
    ...
}

public function tabs_js() {
    ...
}

public function tabs_styles_and_scripts() {
    // style
    wp_register_style(\'jquery-easytabs-style\', get_stylesheet_directory_uri() . \'/inc/easytabs/style.css\', array(), \'\', \'all\');
    wp_enqueue_style(\'jquery-easytabs-style\');

    //script
    wp_register_script(\'jquery-easytabs-min\', get_stylesheet_directory_uri() . \'/inc/easytabs/jquery.easytabs.min.js\', array(\'jquery\'), \'\', false);
    wp_enqueue_script(\'jquery-easytabs-min\');
    wp_register_script(\'jquery-hashchange-min\', get_stylesheet_directory_uri() . \'/inc/easytabs/jquery.hashchange.min.js\', array(\'jquery\'), \'\', false);
    wp_enqueue_script(\'jquery-hashchange-min\');
}

public function __construct() {
    //actions
    add_action(\'wp_enqueue_scripts\', array ( $this, \'tabs_styles_and_scripts\' ));
    add_action(\'wp_head\', array($this, \'tabs_js\'));
}

}

if ( !function_exists( \'the_tabs\' ) ) {
    function the_tabs() {
        echo EasyTabs::get_instance()->get_the_tabs();
    }
}

Edit:

class RFRQ_Tabs {

    public $containerID;
    public $posttype;

    public function __construct( $posttype ) {
        // set vars
        $this->set_container_ID();
        $this->set_posttype($posttype);
        //add scripts and styles
        add_action(\'wp_footer\', array($this, \'scripts\'));
        add_action(\'wp_print_footer_scripts\', array($this, \'ex_scripts\'), 1);
    }

    ...

    public function scripts() {
        echo "<script type=\'text/javascript\'>";
            echo "jQuery(document).ready( function() {";
                echo "jQuery(\'#tab-container-" . $this->get_container_ID() . "\').easytabs();";
            echo "});";
        echo "</script>";
    }


    public function ex_scripts() {        
        if (is_admin())
            return;
        wp_enqueue_script(\'jquery-easytabs-min\', get_stylesheet_directory_uri() . \'/inc/easytabs/jquery.easytabs.min.js\', array(\'jquery\'), \'\', true);
        wp_enqueue_style(\'jquery-easytabs-style\', get_stylesheet_directory_uri() . \'/inc/easytabs/style.css\', array(), \'\', \'all\');
        }  
}
/**
 * RFRQ
 * helper function to instance an tab-object
 */
if (!function_exists(\'the_tabs\')) {
    function the_tabs( $posttype ) {
        $easytabs = new RFRQ_Tabs( $posttype );
        echo $easytabs->get_the_tabs();
    }
}
