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">
Id and Classes are mainly for CSS or JavaScript purpose.Use name for getting the post values
$_POST['firstname'].Following are my guidelines:
1) Whenever we post a form, only
namewill 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
namegets posted.3) In the array
$_POST,nameis thekeyandvaluein it is a value.$_POST['firstname'] <> $_POST['first_name']
It takse name atribute, not the ID one. You have to use
