wordpress更改文件上传目录，需要在 wordpress\wp-includes 下，修改function.php函数

在配置文件结尾添加

/**	wordpress年月日文件目录**/
	function custom_upload_directory( $uploads ) {
		date_default_timezone_set("Asia/Shanghai");//设置时区
		$subdir = date("Y/m/d");//设置目录格式
		$uploads['subdir'] = $subdir;
		$uploads['path'] = $uploads['basedir'].DIRECTORY_SEPARATOR.$subdir;
		$uploads['url'] = $uploads['baseurl'].'/'.$subdir;
		return $uploads;
	}
	add_filter( 'upload_dir', 'custom_upload_directory' );
