The way you are calling a php page is good. That is from HTML.
您调用 php 页面的方式很好。那是来自 HTML。
What I think, you are getting this wrong. A class showNameto get name from database and enterNameto save in database. Well what I suggest that should be a function within one single class.
我的想法是，你弄错了。一个类showName从数据库中获取名称和enterName数据库保存。好吧，我建议它应该是一个类中的一个函数。
<?php
class Name
{
public $name;
public function showName()
{
/**
Put your database code here to extract from database.
**/
return($this->name);
}
public function enterName($TName)
{
$this->name = $TName;
/**
Put your database code here.
**/
}
}
?>
In checking.phpyou can include:
在checking.php你可以包括：
<?php
include_once("name_class.php");
$name = $_POST['name']; //add name attribute to input tag in HTML
$myName = new Name();
$myName->enterName($name); //to save in database/
$name=$myName->showName(); //to retrieve from database.
?>
This way you can achieve this, this is just an overview. It is much more than that.
这样您就可以实现这一点，这只是一个概述。远不止这些。
