这是我在函数中的代码。php

$custom_header_args=array(
    \'default-image\'          => \'\',
    \'width\'                  => 500,
    \'height\'                 => 500,
    \'flex-height\'            => true,
    \'flex-width\'             => true,
    \'uploads\'                => true,
    \'random-default\'         => false,
    \'header-text\'            => true,
    \'default-text-color\'     => \'\',
    \'wp-head-callback\'       => \'\',
    \'admin-head-callback\'    => \'\',
    \'admin-preview-callback\' => \'\',
);
add_theme_support( \'custom-header\' ,$custom_header_args);

这是标题中的代码。php

<img src="<?php header_image(); ?>" height="<?php get_custom_header()->height ?>" width="<?php get_custom_header()->width; ?>" alt="">
<?php wp_nav_menu( array(\'theme_location\'  => \'primary\') ); ?>

我的问题是它不会改变我头部图像的高度和宽度。问题是什么？

<img src="<?php header_image(); ?>" height="<?php echo get_custom_header()->height; ?>" width="<?php echo get_custom_header()->width; ?>" alt="">
<?php wp_nav_menu( array(\'theme_location\'  => \'primary\') ); ?>
