how to acces super variable $_POST in PDO - php

Question

In my PDO statement I am using this following method to insert data to SQL:
//insert into database with a prepared statement
$stmt = $db->prepare('INSERT INTO members (username,password,email,active) VALUES (:username, :password, :email, :active)');
$stmt->execute(array(
':username' => $_POST['username'],
':password' => $hashedpassword,
':email' => $_POST['email'],
':active' => $activasion
));
My problem is I get a warning message saying Dont Access superglobal variable $_post directly
And after google i found this solution filter_input(INPUT_POST, 'var_name') instead of $_POST['var_name']
but this is for PHP
Is there any method for PDO how do i replace $_POST and $_GET in PDO?

Answer 1

PDO is not a different language. It is a PHP extension used to connect and operate on a datasource.
You can use filter_input(INPUT_POST, 'username') without a problem in the code you have there.
$stmt = $db->prepare('INSERT INTO members (username,password,email,active) VALUES (:username, :password, :email, :active)');
$stmt->execute(array(
':username' => filter_input(INPUT_POST, 'username'),
':password' => $hashedpassword,
':email' => filter_input(INPUT_POST, 'email'),
':active' => $activasion
));
This should work just fine, but I don't see why you can't just access $_POST directly, can't se a problem with it.

Answer 2

The filter_input(INPUT_POST, 'username') instead of $_POST['username'] should work.

Answer 3

use the $_POST values in a variable
$stmt = $db->prepare('INSERT INTO members (username,password,email,active) VALUES (:username, :password, :email, :active)');
$username = $_POST['username'];
$email = $_POST['email'];
$stmt->execute(array(
':username' => $username,
':password' => $hashedpassword,
':email' => $email,
':active' => $activasion
));
