/*This is a PHP script containing the majority of my forms, which I have made into functions. It keeps all the back-end data together, meaning the other PHP
files are a lot simpler, as I only need to call the functions if I need to use any of them, less code repitition meaning maximum efficency.
Again it is a required script so files relying on this will have it being required and will not parse if this file cannot be parsed by the server.*/

对不起他们是大文件。林新在这里:(不知道如何发布大数量的代码。
干杯
什么ü想要做的* owner_ID *删除？ – diEcho
你已经在函数文件中有'$ aOwner = mysql_insert_id（）;'，你还想要什么？ – Shef
我真的不知道这个问题，但是如果你想获得输入到数据库的最后一个ID（它的自动增量与否），请使用sql查询以desc顺序获取数据并将其限制为一个 – ahoura
