Using data from sql table within condition in PHP - php

Question

I am very new to coding.
I am trying to select data from a table in SQL then use this data as part of a condition in a PHP If statement. The code I am using appears below. The echo $row["endsequence"]; line shows the correct value has been retrieved from the database, but the record isn't being updated as I need it to be in the final part of code. Any help much appreciated.
<?php
$result = filter_var($_GET['result'], FILTER_SANITIZE_STRING);
$action = filter_var($_GET['action'], FILTER_SANITIZE_STRING);
$pupilid = filter_var($_GET['pupilid'], FILTER_SANITIZE_NUMBER_INT);
$pathwayid = filter_var($_GET['pathwayid'], FILTER_SANITIZE_NUMBER_INT);
$stageid = filter_var($_GET['stageid'], FILTER_SANITIZE_NUMBER_INT);
$resourceid = filter_var($_GET['resourceid'], FILTER_SANITIZE_NUMBER_INT);
$servername = "localhost";
$username = "root";
$password = "root";
$dbname = "planit";
// Create connection
$conn = mysqli_connect($servername, $username, $password, $dbname);
$sql = "SELECT endsequence FROM resources WHERE id= " . $resourceid;
$result = $conn->query($sql);
if ($result->num_rows > 0) {
// output data of each row
while($row = $result->fetch_assoc()) {
echo $row["endsequence"];
}
} else {
echo "0 results";
}
if ($result == 'fail' && $action == 'tryagain' && $row['endsequence'] == "2") {
$sql1 = "UPDATE pupils SET activeresourceid = (SELECT nextresourceid FROM resources WHERE id=$resourceid) WHERE id=$pupilid";
}
if ($conn->query($sql) === TRUE) {
echo "Record updated successfully";
} else {
echo "Error updating record: " . $conn->error;
}
if ($conn->query($sql1) === TRUE) {
echo "Record updated successfully";
} else {
echo "Error updating record: " . $conn->error;
}
mysqli_close($conn);
?>
