编辑按钮代码出错

Question

大家好我在phpmyadmin上有一张表，显示在我的主页上。 我为用户创建了不同的模式（添加联系人，编辑和删除模式），以便将更多信息添加到数据库中，或者删除甚至编辑。现在添加和删除模式工作得很好，但由于某些原因，编辑根本不起作用。

编辑：编辑按钮正在运行，但它不会在以下字段中显示当前数据：

姓名：Jurgen

手机：48854

现在它显示了这个：

名称：

移动：

只是空着。我需要它来显示当前数据

然后用户可以更改他们想要的内容并单击“更新”。 （更新已经有效，它确实会更改数据，但我需要在他们点击编辑时显示原件）

这是我的homepage.php代码（我希望它是你需要的正确代码） 再次感谢所有帮助^^
