I want to check if some column of specify user is holding a value higher than 0.
Problem
When doing the query, and then executing it , Im getting this error:
Fatal error: Cannot use object of type PDOStatement as array in C:\xampp\htdocs\recover\admin\create.php on line 40
My code (The query + execute):
if (isset($_SESSION['user'])) {
$admin = $CONNECT_TO_DATABASE->prepare("SELECT * FROM admin WHERE username = :username");
$admin->bindValue(':username', $_SESSION['user']);
$admin->execute();
Line of error (40):
if ($settings['create_admins'] > 0 || $admin['super_admin'] > 0 ) {
Question:
Why am I getting this error? How do I fix it?
I tried doing this:
$admin = $CONNECT_TO_DATABASE->prepare("SELECT * FROM admin WHERE username = :username");
$admin = $admin->bindValue(':username', $_SESSION['user']);
$admin = $admin->execute();
and getting another error:
Fatal error: Call to a member function execute() on a non-object in C:\xampp\htdocs\recover\admin\create.php on line 38
Thanks!
EDIT: I need the ->fetch object, but I have just done this, and got rid of the errors.. But it doesn't affect? I mean I am echoing that row, and it gives me a null (nothing). Why?
$admin = $CONNECT_TO_DATABASE->prepare("SELECT * FROM admin WHERE username = ".$_SESSION['user']."");
$admin = $admin->fetch();
From:
$admin = $CONNECT_TO_DATABASE->prepare("SELECT * FROM admin WHERE username = :username");
[...]
if ($settings['create_admins'] > 0 || $admin['super_admin'] > 0 ) {
$admin
is of type PDOStatament
which is a class and not an array. Therefore you can't call the []
operator on it.
Also you should really not alway assign $admin
to the return result of every method because most of the PDOStatament
's methods return boolean values:
$admin = $CONNECT_TO_DATABASE->prepare("SELECT * FROM admin WHERE username = :username");
$admin->bindValue(':username', $_SESSION['user']);
$admin->execute();
To retrieve the super_admin
column from the admin
table you should add (after the execute()
statement):
$result = $admin->fetch(PDO::FETCH_ASSOC);
which will populate (hopefully, it depends on what's the table schema) $result['super_admin']
.
try this:
$sql = "SELECT * FROM admin WHERE username = ?";
$stmt = $CONNECT_TO_DATABASE->prepare($sql);
$stmt->execute(array($_SESSION['user']));
$admin = $stmt->fetch();
if($admin) {
//do something if query returns row(s)
