wordpress修改默认的图片上传目录地址

把以下代码添加在主题的functions.php中：

function switch_upload_dir($uploads) {
    $siteurl = get_option( 'siteurl' );
    $uploads['path'] = WP_CONTENT_DIR . '/switch';
    $uploads['url'] = $siteurl . '/wp-content/switch';
    $uploads['subdir'] = '';
    $uploads['basedir'] = $uploads['path'];
    $uploads['baseurl'] = $uploads['url'];
    $uploads['error'] = false;
    return $uploads;
}
add_filter('upload_dir', 'switch_upload_dir');

修改后，上传目录就变成了wp-content/switch/目录。
