我正在疯狂地尝试让它工作…只需将其数据库记录的ID作为参数传递，可能作为隐藏字段，然后在下一页使用它从数据库中提取其记录。只需将其数据库记录的ID作为参数传递，可能作为隐藏字段，然后使用它在下一页从数据库中提取他们的记录。这个想法是你传递玩家的ID（可以是GET或POST方法），我认为最好的方法是POST，因为你可以将ID传递到URL中 例如： player_id=1 Vince Young如果您创建指向此页面的链接，它将显示编辑页面 player_id=2 Ryan Tannehill如果创建指向此页面的链接，它将显示编辑页面 等等 当然，你必须考虑一些事情：

我相信你的错误是由这里造成的 “从ID=”的ff_投影中选择*”$贴上你的身份证。“'” 在选择好的前，您已经开始了双引号 但是，当您达到ID=时，您结束了这组引号 删除双引号 换句话说
"SELECT * FROM ff_projections WHERE ID = '$posted_id'"
"SELECT * FROM ff_projections where ID='" . $posted_id . "'"

在包含这些按钮的每个表单中，输入与每个播放器相关联的记录的ID号。然后，您可以在qb-edit.php页面上以
