更新:看来5.0和更高版本将支持此功能。参见门票#43458
这是怎么图标(.ico
)文件中显示媒体网格视图:
这是微型模板的相应部分:
<# } else if ( 'image' === data.type && data.sizes ) { #>
<div class="centered">
<img src="{{ data.size.url }}" draggable="false" alt="" />
</div>
<# } else { #>
<div class="centered">
<# if ( data.image && data.image.src && data.image.src !== data.icon ) { #>
<img src="{{ data.image.src }}" class="thumbnail" draggable="false" />
<# } else { #>
<img src="{{ data.icon }}" class="icon" draggable="false" />
<# } #>
</div>
<div class="filename">
<div>{{ data.filename }}</div>
</div>
<# } #>
图标的位置data.sizes
是空的。
wp_mime_type_icon
筛选器网站图示的mime类型为image/x-icon
。
我设法通过以下方式.ico
在Media Grid视图中显示文件:
add_filter( 'wp_mime_type_icon', function( $icon, $mime, $post_id )
{
if( $src = false || 'image/x-icon' === $mime && $post_id > 0 )
$src = wp_get_attachment_image_src( $post_id );
return is_array( $src ) ? array_shift( $src ) : $icon;
}, 10, 3 );
在这里重要的是保持wp_get_attachment_image_src
as 的第三个参数$icon = false
(默认)以避免无限循环!
图标显示如下:
wp_prepare_attachment_for_js
筛选器加载媒体网格视图时,将调用wp_ajax_query_attachments
处理程序。它执行以下附件查询:
$query = new WP_Query( $query );
$posts = array_map( 'wp_prepare_attachment_for_js', $query->posts );
在此wp_prepare_attachment_for_js
功能中,各种信息会添加到WP_Post
帖子中,并使用以下信息过滤:
return apply_filters( 'wp_prepare_attachment_for_js', $response, $attachment, $meta );
输出是$response
数组。
我们可以使用此过滤器为网站图标添加缺少的尺寸:
add_filter( 'wp_prepare_attachment_for_js', function( $response, $attachment, $meta )
{
if( 'image/x-icon' === $response['mime']
&& isset( $response['url'] )
&& ! isset( $response['sizes']['full'] )
)
{
$response['sizes'] = array( 'full' => array( 'url' => $response['url'] ) );
}
return $response;
}, 10, 3 );
然后他们会像这样显示:
请注意,我们只设置的url
一部分,而不是width
,height
和orientation
。例如,我们可以借助该wp_get_attachment_image_src()
功能进一步扩展解决方案以添加此数据。但是我留给你;-)
$response
例子:这是文件$response

对这些示例的一部分特别感兴趣。
