get value of input element with "id" or "name"
Solution 1
Id and Classes are mainly for CSS or JavaScript purpose.Use name for getting the post values $_POST['firstname']
.
<input name="firstname" type="text" id="first_name">
Solution 2
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.
Solution 3
$_POST['firstname'] <> $_POST['first_name']
It takse name atribute, not the ID one. You have to use
$fname = $_POST['firstname'];

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">
