我使用名称空间和自动加载编写了一个WP主题。在我开始使用WP类之前，一切都很顺利，我当然理解WP类，因为我了解名称空间是如何工作的。我的问题是，有没有一种方法可以在我的主题类中使用Wordpress类，例如我想使用$wp_customize, 的实例WP_Customize_Manager? 我如何做到这一点，保持我的OOP主题结构。

UPDATE:

class ColorController extends BaseController
{
    public function register()
    {
        add_action(\'customize_register\', array($this, \'theme_customize_register\'));
    }

    public function theme_customize_register($wp_customize)
    {
        // Text color
        $wp_customize->add_setting(\'text_color\', array(
            \'default\' => \'\',
            \'transport\' => \'refresh\',
        ));

        $wp_customize->add_control(new \\WP_Customize_Color_Control($wp_customize, \'text_color\', array(
            \'section\' => \'colors\',
            \'label\' => esc_html__(\'Text color\', \'theme\'),
        )));

        // Link color
        $wp_customize->add_setting(\'link_color\', array(
            \'default\' => \'\',
            \'transport\' => \'refresh\',
            \'sanitize_callback\' => \'sanitize_hex_color\',
        ));

        $wp_customize->add_control(new \\WP_Customize_Color_Control($wp_customize, \'link_color\', array(
            \'section\' => \'colors\',
            \'label\' => esc_html__(\'Link color\', \'theme\'),
        )));

        // Accent color
        $wp_customize->add_setting(\'accent_color\', array(
            \'default\' => \'\',
            \'transport\' => \'refresh\',
            \'sanitize_callback\' => \'sanitize_hex_color\',
        ));

        $wp_customize->add_control(new \\WP_Customize_Color_Control($wp_customize, \'accent_color\', array(
            \'section\' => \'colors\',
            \'label\' => esc_html__(\'Accent color\', \'theme\'),
        )));

        // Border color
        $wp_customize->add_setting(\'border_color\', array(
            \'default\' => \'\',
            \'transport\' => \'refresh\',
            \'sanitize_callback\' => \'sanitize_hex_color\',
        ));

        $wp_customize->add_control(new \\WP_Customize_Color_Control($wp_customize, \'border_color\', array(
            \'section\' => \'colors\',
            \'label\' => esc_html__(\'Border color\', \'theme\'),
        )));

        // Sidebar background
        $wp_customize->add_setting(\'sidebar_background\', array(
            \'default\' => \'\',
            \'transport\' => \'refresh\',
            \'sanitize_callback\' => \'sanitize_hex_color\',
        ));

        $wp_customize->add_control(new \\WP_Customize_Color_Control($wp_customize, \'sidebar_background\', array(
            \'section\' => \'colors\',
            \'label\' => esc_html__(\'Sidebar Background\', \'theme\'),
        )));
    }
