3,953 PointsProblem with prepared statement task
In challenge "Change the query to a prepared statement that binds the passed argument before executing the query."
I wrote this code:
<?php function get_member($member_id) { include("connection.php");
try {
$results = $db->prepare(
"SELECT member_id, email, fullname, level
FROM members
where member_id = ?"
);
$results = bindParam(1,$member_id);
} catch (Exception $e) {
echo "bad query";
}
$members = $results->fetchAll();
return $members;
}
And I get this answer:
"Bummer! Uncaught Error: Call to undefined function bindParam() in index.php:11"
But this method (miscalled in error as undefined function) is part of PDO class and instanced by $results
<?php
function get_member($member_id) {
include("connection.php");
try {
$results = $db->prepare(
"SELECT member_id, email, fullname, level
FROM members
where member_id = ?"
);
$results = bindParam(1,$member_id);
} catch (Exception $e) {
echo "bad query";
}
$members = $results->fetchAll();
return $members;
}

13,402 PointsThis line is the problem: $results = bindParam(1,$member_id);
"bindParam" is a method of the pdo object, so write something like this:
$results->bindParam(1, $member_id, PDO::PARAM_INT);

3,953 PointsForget it!!! I saw my mistake: $results = bindParam(1,$member_id);
instead of: $results->bindParam(1,$member_id);
