11,897 PointsUse pdo the execute sql query
I dont have a database connection yet, so i dont know what i have to do to make a PDO execute a sql query.
<?php
class sqlRepository extends PDO implements RepositoryInterface
{
public function all($items)
{
$stmt = $dbh->prepare("SELECT * FROM " .$items);
$stmt = execute();
return $stmt->PDO->fetchAll(PDO::FETCH_OBJ);
}
}

Treehouse TeacherHi there, Hugo Zaanen! Remember, this is a class. So very likely, at some point, you will make an instance of that class. You can refer to the instance, which inherits from PDO, as $this
. You also are referencing PDO
as if it is a method on PDO, but it isn't. And your middle line there should run the execute()
method directly on the $stmt
(which is an instance of PDO).
<?php
class sqlRepository extends PDO implements RepositoryInterface
{
public function all($items)
{
$stmt = $this->prepare("SELECT * FROM " .$items); // prepare the PDO object with the SQL you want to run
$stmt->execute(); // run the SQL on the PDO object
return $stmt->fetchAll(PDO::FETCH_OBJ); // get and return all the results returned by the execution of the SQL on the PDO
}
}
Hope this helps!

11,897 PointsYeah, thank you. This works apparently. I thought I already applied it. A friend of mine said that the execute has to contain the $items variabel as a array param. It already used your solution, but i really dont know anymore ;C
