6,339 PointsParameter should be optional error in CRUD Operations with PHP: Task 2 of 2
I'm working on Task 2 of 2 in the CRUD Operations with PHP. Below is the code I've submitted:
<?php
function get_people($filter = false) {
include 'connection.php';
//add code here
try
{
$query = 'select * from people';
if($filter == true)
{
$query .= ' where treehouse=1';
}
$query .= ' order by last_name desc';
$peopleStmt = $db->prepare($query);
$peopleStmt->execute();
return $peopleStmt->fetchAll(PDO::FETCH_ASSOC);
} catch(Exception $e)
{
echo $e->getMessage();
}
}
It tells me that the parameter should be optional. What am I missing?

$query = 'select * from people';

}
$query .= ' order by last_name desc';
$peopleStmt = $db->prepare($query);
$peopleStmt->execute();
return $peopleStmt->fetchAll(PDO::FETCH_ASSOC);
} catch(Exception $e)
{
echo $e->getMessage();
}
}

fails, the previous video shows using null
as a default instead. Making that change passes the challenge.
