我一直在练习php＆amp; mysql，目前我正在创建一个简单的数据库管理器。除了这段代码之外，一切正常：http://snipt.org/vCW0
这段代码应该做的是从数据库中获取所有结果并显示它们，除非显示位置和团队名称，它应该更改位置和团队名称值（我使用缩写插入到数据库中，例如'qb'而不是'Quarterback'来节省空间）到它们的完全等价物（所以'gba'应该显示为'Green Bay Packers'等）（最后是一个用于添加新条目的表格）。它实际上正确显示它们但是当我向数据库添加一个新的播放器时，我收到以下错误：

但是，尽管存在错误，但记录已添加到数据库并显示在页面上。删除记录不会显示任何错误。
