WordPress 媒体库过滤不同类型的文件

WordPress 媒体库过滤不同类型的文件

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:

add-custom-media-type-filters-wpdaxue_com

将下面的代码添加到主题的 functions.php

/**
 * 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;
}

/**
* 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。
