9,547 Pointscall to a member function bindParam() on a non-object in ... on line 16
So I have been working on a personal side project with exactly the similar setup in the php and database series. I am correct up until the point where I have to bind my Param. It is giving me the error listed above. ill input the code
<?php
include('php/contact-form.php');
include('config.php');
$pdo = connect();
if(!empty($_GET['id'])){
$list_id = intval(($_GET['id']));
}
try {
$sql = 'SELECT * FROM items where id = ?';
$sql->bindParam(1, $list_id);
$query = $pdo->prepare($sql);
$query->execute();
} catch(Exception $e) {
echo $e->getMessage();
die();
}
$list = $query->fetch(PDO::FETCH_ASSOC);
?>

Try this:
$sql = 'SELECT * FROM items where id = ?';
$query = $pdo->prepare($sql);
$query->bindParam(1, $list_id);
$query->execute();

6,314 PointsWell caught Hugo and to add to what you said, another reason why Gianni is getting the error message is because he has called bindParam PDOStatement method before declaring a PDOStatement object which only happens when you invoke the prepare() method. So the prepare() method makes a new instance of a PDOStatement that you can bind values or parameters to before executing the query.
In other words, two reasons why the code block generates a fatal error:
Hugo's code block will work perfectly as it avoids both the above problems.
