the name
attribute isn't really necessary when you are not sending data through it. The id
of the form input element can fulfill the purpose of hooking the element with JavaScript and CSS.
The name attribute is used in the HTTP
request sent by your browser to the server as a variable name associated with the data contained in the value
attribute.
Here I'm taking example of extracting data with php in a login form. If you don't know php you wouldn't probably know $_POST
and $_GET
. For now just know that they are used to extract data sent with this HTTP
request.
<form action="login.php">
<input type="text" name="user" value="kittyCat">
<input type="password" name="password" value="querty123">
</form>
Now in login.php
file you can extract the data like this:
$userName = $_POST['user'];
$password = $_POST['password'];
here user
points to the fist input so $username
will be equal to the value
of that input, which is "kittyCat"
. similarly $password
will be equal to "qwerty123"
.
