phpcms后台栏目点击添加内容，报错500，解决方法。

在后台添加文章内容时报错500，在网上找的一个帖子说是/phpcms/modules/content/fields/video/form.inc.php在上传至服务器时出现错误，果然发现服务器下的form.inc.php文件仅有2KB，而本地文件有8KB，把本地的覆盖过去以后就可以添加内容了。form.inc.php正常代码如下：

	function video($field, $value, $fieldinfo) {
		$value_data = '';
		//获取flash上传属性
		pc_base::load_app_class('ku6api', 'video', 0);
		$setting = getcache('video', 'video');
		if(empty($setting)) return L('please_input_video_setting');
		$ku6api = new ku6api($setting['sn'], $setting['skey']);
		$flash_info = $ku6api->flashuploadparam();
		
		//获取上传的视频
		$key = 0;
		$list_str = "
";
		if($value) {
			$video_content_db = pc_base::load_model('video_content_model');
			$video_store_db = pc_base::load_model('video_store_model');
			$videos = $video_content_db->select(array('contentid'=>$this->id), 'videoid, listorder', '', '`listorder` ASC', '', 'videoid');
			if (!empty($videos)) {
				$videoids = '';
				foreach ($videos as $v) {
					$videoids .= $v['videoid'].',';
				}
				$videoids = substr($videoids, 0, -1);
				$result = $video_store_db->select("`videoid` IN($videoids)", '`videoid`, `title`, `picpath`', '', '', '', 'videoid');
				if (is_array($result)) {
					//首先对$result按照$videos的videoid排序
					foreach ($videos as $_vid => $v) {
						$new_result[] = $result[$_vid];
					}
					unset($result, $_vid, $v);
					foreach ($new_result as $_k => $r) {
						$key = $_k+1;
						$picpath = $r['picpath'] ? $r['picpath'] : IMG_PATH.'nopic.gif';
						$list_str .= "
".L('listorder')." ".L('delete')."
";
					}
				}
			}
		}
		$list_str .= "
";
		$data = '';
		if (!defined('SWFOBJECT_INIT')) {
			$data .= '';
			$data .= '';
			define('SWFOBJECT_INIT', 1);
			$data .= '
';
		}
		$authkey = upload_key("$upload_number,$upload_allowext,$isselectimage");
		$video_store_sel = defined('IN_ADMIN') ? '
 '.L('videoes_store').' 
' : '';
		$vms_str = $flash_info['allow_upload_to_vms'] ? ''. L('upload_to_ku6vms', '', 'video').' ' : '';
		return $data.'
