WordPress自定义分类法中增加图片字段，js无法获取媒体权限，点击上传不生效；请问需要怎么修改；
操作步骤是：
1、新建了自定义分类法
2、创建自定义分类法的字段
3、自定义字段的点击添加图片时，不生效
<?php
add_action('init', 'ashu_post_type');
function ashu_post_type() {
/**********幻灯片*****************/
register_post_type( 'banner',
array(
'labels' => array(
'name' => '幻灯片',
'singular_name' => '幻灯片',
'add_new' => '添加',
'add_new_item' => '添加新幻灯片',
'edit_item' => '编辑幻灯片',
'new_item' => '新幻灯片'
),
'public' => true,
'has_archive' => false,
'exclude_from_search' => true,
'menu_position' => 5,
'supports' => array( 'title','thumbnail',),
)
);
}

调用代码
<?php

query_posts($args);
if( have_posts() ) : ?>
<div id="banner">
<div id="show">
<?php

if($image_url!=''){ ?>
<div class="show_item">
<a href="<?php echo get_post_meta($post->ID,'banner_d',true);?>">
<img src="<?php echo $image_url; ?>" alt="<?php the_title(); ?>" />
</a>
</div>
<?php } endwhile; ?>
</div>
</div>
<?php endif; wp_reset_query(); ?>
<?php if (of_get_option('banner')) { ?>
