我有以下两个自定义控件，它们显示用于显示/隐藏内容的复选框。每个复选框后面都有一个active_callback 选中/取消选中复选框时显示/隐藏相应控件的。

// Display About Block Button
$wp_customize->add_setting( \'display_about_block_button\', array(
    \'default\'           => true
) );
$wp_customize->add_control( \'display_about_block_button\', array(
    \'label\'             => __( \'Display About Button\', \'my_theme_name\' ),
    \'type\'              => \'checkbox\',
    \'section\'           => \'about\',
    \'active_callback\'   => \'display_about_block_callback\'
) );
function display_about_block_button_callback( $control ) {
    if ( $control->manager->get_setting( \'display_about_block_button\' )->value() == true ) {
        return true;
    } else {
        return false;
    }
}

// Display About Block
$wp_customize->add_setting( \'display_about_block\', array(
    \'default\'           => true
) );
$wp_customize->add_control( \'display_about_block\', array(
    \'label\'             => __( \'Display About Block\', \'my_theme_name\' ),
    \'type\'              => \'checkbox\',
    \'section\'           => \'about\'
) );
function display_about_block_callback( $control ) {
    if ( $control->manager->get_setting( \'display_about_block\' )->value() == true ) {
        return true;
    } else {
        return false;
    }
}

除了问题是About Block Button 下面是About Block. 我希望能够隐藏About Block Button 如果About Block 显示，但也可以隐藏About Block Button 如果About Block 完全隐藏（无需选中两个框）。因此，它需要两个active_callback\'是这样的：

// About Block Button Text
$wp_customize->add_setting( \'about_block_button_text\', array(
    \'default\'           => __( \'Read More\', \'my_theme_name\' )
) );    
$wp_customize->add_control( \'about_block_button_text\', array(
    \'label\'             => __( \'About Button Text\', \'my_theme_name\' ),
    \'type\'              => \'text\',
    \'section\'           => \'about\',
    \'active_callback\'   => \'display_about_block_button_callback\',
    \'active_callback\'   => \'display_about_block_callback\'
) );

不幸的是，这两者都不能接受active_callback\'s、 如何在一个控件上有两个（或可能更多）活动回调？

// About Block Button Text
$wp_customize->add_setting( \'about_block_button_text\', array(
    \'default\'           => __( \'Read More\', \'my_theme_name\' )
) );    
$wp_customize->add_control( \'about_block_button_text\', array(
    \'label\'             => __( \'About Button Text\', \'my_theme_name\' ),
    \'type\'              => \'text\',
    \'section\'           => \'about\',
    \'active_callback\'   => function( $control ) {
        return ( 
            display_about_block_button_callback( $control )
            &&
            display_about_block_callback( $control )
        );
    },
) );
