Question

这里有一些我正在研究的代码。一切正常，我会输入我输入ID的部分，然后它会显示该ID行中的信息，还有2个弹出框，我可以在其中写入变量的新值。还有2个按钮，一个用于确认编辑已写入框，另一个用于从数据库中删除该行。

我仍然处于编程的基础知识，你可以看到并且在这部分代码中结构有问题吗？

任何人都可以帮助我让这两个提交按钮正常工作。

谢谢大家。：）

<form action="test2.php" method="POST" >
Insert ID of task to edit: <input type="text" name="idnumber"/>
<input type="submit" name="ids" value="Find task"/> <br />
</form>

PHP提交按钮/结构？
