WordPress媒体库显示文件大小（占用空间）和尺寸

如果你想在后台 > 媒体库，直截了当地了解上传的文件大小（占用空间）和尺寸，如下图所示，只要按照本文的方法进行操作即可。

显示占用空间：下载安装 Media File Sizes 插件即可，All Sizes 表示包括缩略图在内所有大小，Original 表示原图大小。

显示尺寸（图片文件）：

将下面的代码添加到当前主题的functions.php 即可：

/**

 * From https://www.wpdaxue.com/display-image-size-dimensions.html
 */
add_filter('manage_upload_columns', 'size_column_register');
function size_column_register($columns) {
	$columns['dimensions'] = __('Dimensions');
	return $columns;
}
 
add_action('manage_media_custom_column', 'size_column_display', 10, 2);
function size_column_display($column_name, $post_id) {
	if( 'dimensions' != $column_name || !wp_attachment_is_image($post_id))
		return;
	list($url, $width, $height) = wp_get_attachment_image_src($post_id, 'full');
	echo esc_html("{$width}×{$height}");
}

/**

* From https://www.wpdaxue.com/display-image-size-dimensions.html
*/
add_filter(‘manage_upload_columns’, ‘size_column_register’);
function size_column_register($columns) {
$columns[‘dimensions’] = __(‘Dimensions’);
return $columns;
} add_action(‘manage_media_custom_column’, ‘size_column_display’, 10, 2);
function size_column_display($column_name, $post_id) {
if( ‘dimensions’ != $column_name || !wp_attachment_is_image($post_id))
return;
list($url, $width, $height) = wp_get_attachment_image_src($post_id, ‘full’);
echo esc_html("{$width}×{$height}");
}
