Inserting form data and adding 1 day - php

Question

I have a function that inserts into a users table, I want to know if it is possible to -1 day from the "dob" and insert into reminder column through the function
public function AddUser($email, $name, $dob)
{
try {
$db = DB();
$query = $db->prepare("INSERT INTO users(email, name, dob, reminder) VALUES (:email, :name, :dob, :reminder)");
$query->bindParam("email", $email, PDO::PARAM_STR);
$query->bindParam("name", $name, PDO::PARAM_STR);
$query->bindParam("dob", $dob, PDO::PARAM_STR);
$query->bindParam("reminder", $dob, PDO::PARAM_STR);
$query->execute();
return $db->lastInsertId();
} catch (PDOException $e) {
exit($e->getMessage());
}
}
Is there anything I can do with this line to do it on INSERT
Something along the lines of
$query->bindParam("reminder", $dob DATE_ADD(now(), INTERVAL -1 DAY)); PDO::PARAM_STR);
If this is not possible could you please give me some pointers

Answer 1

Youn should use the :remainder in mysql date_add function eg:
$query = $db->prepare("INSERT INTO users(email, name, dob, reminder)
VALUES (:email, :name, :dob, DATE_ADD(:reminder, INTERVAL -1 DAY) )");
$query->bindParam("email", $email, PDO::PARAM_STR);
$query->bindParam("name", $name, PDO::PARAM_STR);
$query->bindParam("dob", $dob, PDO::PARAM_STR);
$query->bindParam("reminder", $dob, PDO::PARAM_STR);
