上传的文件多了，在后台的媒体库要快速找到某些类型的文件，不是一件容易的事，所以我们最好是在媒体库中添加文件类型过滤功能。比如下图所示：
将下面的代码添加到主题的 functions.php
1 2 3 4 5 6 7 8 9 10 11 12 |
/** * WordPress 媒体库过滤不同类型的文件 * https://www.wpdaxue.com/add-custom-media-type-filters.html */ add_filter( 'post_mime_types', 'modify_post_mime_types' ); function modify_post_mime_types( $post_mime_types ) { // 添加查询 application 这个大类的文件 $post_mime_types['application'] = array( __( '应用文件' ), __( '管理应用文件' ), _n_noop( '应用文件 <span class="count">(%s)</span>', '应用文件 <span class="count">(%s)</span>' ) ); // 添加查询 application 大类下的 ZIP 文件 $post_mime_types['application/zip'] = array( __( 'ZIP' ), __( '管理ZIP文件' ), _n_noop( 'ZIP <span class="count">(%s)</span>', 'ZIP <span class="count">(%s)</span>' ) ); return $post_mime_types; } |
你就可以看到上图的效果，我们只需要修改 post_mime_types 的类型参数和相应的文字即可。post_mime_types 默认允许的类型如下，分为 图像（image）、视频（Video）、文本（Text）、音频（Audio）和 应用（application） 五大类。上面的代码使用 $post_mime_types[‘application’] 查询的是 应用（application）这类文件；使用 $post_mime_types[‘application/zip’] 查询 应用 这个大类下的 zip 文件。你只要理解了，就可以根据自己的需求来改代码了。
