I am trying to learn php and I have seen some videos and tutorials, when creating session variables which values are going to be pulled out from values entered in input elements, the "id" of the input element is the one that matters while when checking if a submit button was clicked is the "name" of the input element what matters?
<?php
if (isset($_POST['Register'])) { //Register is the "name"
session_start();
$Fname = $_POST['first_name']; //first_name is the "id"
...
}
?>
<!doctype html>
...
<form action="" method="post" name="registerform" id="registerform">
<input name="firstname" type="text" id="first_name">
...
<input name="Register" type="submit" id="register" value="submit">

Following are my guidelines:
1) Whenever we post a form, only name will be considered for getting posted value.
e.g.
<input type="text" name="fname" id="first_name"/>
Here we get $_POST['fname'] Not $_POST['first_name'];
2) Id and classes are there for CSS/JS purposes. Thus if you add whatever class/id attributes to the element,
Only name gets posted.
3) In the array $_POST, name is the key and value in it is a value.
