我有一个内置的表单，你可以用你的记录上传两个文件，文件将保存到服务器，信息将输入到mySQL数据库。文件现在上传和删除成功，但我无法获得＆＃34;更新＆＃34;功能工作。我希望从服务器删除旧文件，上传新文件，并在mySQL数据库中更新信息。
我目前收到此错误：
错误：`visible` =＆＃39; N＆＃39;，`homepage` =＆＃39; N＆＃39;，`fa_id` =＆＃39;＆＃39;，`title` =＆＃ 39;测试者＆＃39;，`caption` =＆＃39;＆＃39;，`url` =＆＃39;＆＃39;，`month` =＆＃39;＆＃39;，`date` = ＆＃39;＆＃39;，`year` =＆＃39;＆＃39;，`summary` =＆＃39;＆＃39;，`full_text` =＆＃39;＆＃39;，`image `=＆＃39; 51837 - ＆＃39;，`image_type` =＆＃39;＆＃39;，`image_size` =＆＃39; 0＆＃39; `file` =＆＃39; 34076 - ＆＃39;，`file_type` =＆＃39;＆＃39;，`file_size` =＆＃39; 0＆＃39;在哪里`events` .id` = 44 LIMIT 1
非常感谢任何帮助。谢谢！
