Front End Web Development Techdegree Student 21,661 PointsHow to pass method in a statement?
I am on the quiz, and i cannot understand how to do it. from my understanding, if you want to get method of a object, you do a php $results->method();
but it is not happening. maybe i am doing something wrong or not understood the question.
<?php
include "helper.php";
/*
* helper.php contains
* $results->query("SELECT member_id, email, fullname, level FROM members");
*/

<?php
include "helper.php";
$members = $results->fetchAll(PDO::FETCH_ASSOC);
foreach ($members as $member) {
$member_id = $member[member_id];
$email = $member[email];
$fullname = $member[fullname];
$level = $member[level];
send_offer($member_id, $email, $fullname, $level);
}

Full Stack JavaScript Techdegree Student 21,416 PointsThank you for the input @cynthiaarnow.
She kinda went through all of that. In the video before the challenge, Alena shows that you need to do something like the $members = $results->fetchAll(PDO::FETCH_ASSOC); to fetch the results as an array.
The challenge explanation is saying that you need to loop though the results, which means that now you need a foreach loop. When you do foreach($members as $member), the $member will become the array fetched from the sql query. It will look kinda like this:
$member = [
"member_id" => "info",
"email" => "info",
"fullname" => "info",
"level" => "info"
]
The member_id, email, fullname and level are now keys and their info are the values. We need to get their values, so for that you do $member["member_id"], $member["email"], $member["fullname"], $member["level"].
Since we already have the function and know what the parameters are, we just need to give the the values needed.
$member_id = $member["member_id"];
$email = $member["email"];
$fullname = $member["fullname"];
$level = $member["level"];
And now we just call the function.
send_offer($member_id, $email, $fullname, $level);
So it becomes like Cindy showed.
<?php
include "helper.php";
$members = $results->fetchAll(PDO::FETCH_ASSOC);
foreach ($members as $member) {
$member_id = $member["member_id"];
$email = $member["email"];
$fullname = $member["fullname"];
$level = $member["level"];
send_offer($member_id, $email, $fullname, $level);
}
