13,737 PointsLast Challenge in Integrating PHP with Databases- help!
I coded: While ($row = $results->fetch(PDO::FETCH_ASSOC)) { $item[$row["genre_id"]] []=$row["genre"]; }
and it keeps telling me nothing is added to the $item["genres"] array
<?php
include "helper.php";
/*
* helper contains the following variables:
* $item is an array that contains details about the library item
* $results is a PDOstatement object with our genre results.
*/
While ($row = $results->fetch(PDO::FETCH_ASSOC)) {
$item[$row["genre_id"]] []=$row["genre"];
}
?>

4,954 PointsYou don't have an associative array where the key is "genres" - your associative array is using a key that's tied to the value of genre_id.
After the loop terminates, what happens if you put in
var_dump($item)
Lets say that genre_id is numeric. You're creating an array where the index is going to be a number:
genre_id, genre
0,Religious
1,Horror
2,Science Fiction
Using your existing code:
$item[1] will be "Horror"
If you want an associative array, where you can do something like
$myGenreID = $item["Horror"];
Then the key for $item on the left-hand-side would need to be $row["genre"] and not the genre_id
