wordpress 如何修改上传文件的目录

wordpress 默认的上传目录是 /wp-content/uploads 。通过wordpress的钩子可以对这个目录进行修改。比如修改为 网站根目录下的 upload 目录。

wordpress修改上传文件的目录

  add_filter('upload_dir', function ($uploads) {
      $upload_path = ABSPATH . 'upload';
      $upload_url_path = home_url('upload');

      if (empty($upload_path) || 'wp-content/uploads' == $upload_path) {
          $uploads['basedir'] = WP_CONTENT_DIR . '/uploads';
      } elseif (0 !== strpos($upload_path, ABSPATH)) {
          $uploads['basedir'] = path_join(ABSPATH, $upload_path);
      } else {
          $uploads['basedir'] = $upload_path;
      }

      $uploads['path'] = $uploads['basedir'] . $uploads['subdir'];

      if ($upload_url_path) {
          $uploads['baseurl'] = $upload_url_path;
          $uploads['url'] = $uploads['baseurl'] . $uploads['subdir'];
      }
      return $uploads;
  }
  );

修改前后的对比，其实就是 返回的 $uploads 的值

# 修改前
array(6) {
  ["path"]=>
  string(65) "/web/www.wpcode.cn/webroot/wp-content/uploads/2021/11"
  ["url"]=>
  string(48) "https://www.wpcode.cn/wp-content/uploads/2021/11"
  ["subdir"]=>
  string(8) "/2021/11"
  ["basedir"]=>
  string(57) "/web/www.wpcode.cn/webroot/wp-content/uploads"
  ["baseurl"]=>
  string(40) "https://www.wpcode.cn/wp-content/uploads"
  ["error"]=>
  bool(false)
}

# 修改后
array(6) {
  ["path"]=>
  string(53) "/web/www.wpcode.cn/webroot/upload/2021/11"
  ["url"]=>
  string(36) "https://www.wpcode.cn/upload/2021/11"
  ["subdir"]=>
  string(8) "/2021/11"
  ["basedir"]=>
  string(45) "/web/www.wpcode.cn/webroot/upload"
  ["baseurl"]=>
  string(28) "https://www.wpcode.cn/upload"
  ["error"]=>
  bool(false)
}
