默认WordPress上传图片或者附件都会在wp-content/uploads目录中。我们有些朋友希望更换目录，这里我们如何设置呢？
function change_upload_dir($uploads) {
$siteurl = get_option( 'siteurl' );
$uploads['path'] = WP_CONTENT_DIR . '/newurl';
$uploads['url'] = $siteurl . '/wp-content/newurl';
$uploads['subdir'] = '';
$uploads['basedir'] = $uploads['path'];
$uploads['baseurl'] = $uploads['url'];
$uploads['error'] = false;
return $uploads;
}
add_filter('upload_dir', 'change_upload_dir');
添加到当前主题 Functions.php 文件中。根据设置，我们可以更换 newurl的地址目录。
