Answer 1

The way you are calling a php page is good. That is from HTML.

What I think, you are getting this wrong. A class showName to get name from database and enterName to save in database. Well what I suggest that should be a function within one single class.

<?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.php you can include:

<?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.
