Limit foreach loop to only one user?
Question
I have a system where I want to limit the foreach to a designated user:
My output shows every date Enrolled, I could limit it to only one, but if I do, the single thing shown will be shown to every user as well.
This should only show one Enrolled Since and Not Enrolled Since, but I don't know if I should use an if statement or use a row query. I tried it but it only outputs error "Uncaught Error: Call to a member function result_array() on array in . . ."
(below is the code I tried to use row for, but outputs the said error above.)
<?php
$result_array = $res->result_array();
$results = array();
foreach ($res->result_array() as $row)
{
$results[] = $row;
}
?>
Here is my codes latest code called viewlogs.php
<?php
session_start();
if (!isset($_SESSION['username']))
{
header('location: login.php');
die();
}
?>
<?php
require"config.php";
require"sqlsrv.php";
$id=$_GET['id'];
$sql= 'SELECT * FROM students WHERE id= :id';
$stmt = $db-> prepare($sql);
$stmt->execute([':id' => $id ]);
$data= $stmt->fetch(PDO::FETCH_OBJ);
$query= 'SELECT EmployeeNo, FirstName, MiddleName, LastName, DateHired, ResignationDate FROM TA3.dbo.Employees';
$statement = $conn->query($query);
$statement->execute();
$res=$statement->fetchAll(PDO::FETCH_OBJ);
$q= 'SELECT TimeLogID, EmployeeID, RecordDate, RecordTime, Type, ActualTime FROM TA3.dbo.TimeLogs';
$st = $conn->query($q);
$st->execute();
$re=$st->fetchAll(PDO::FETCH_OBJ);
if (isset ($_POST['fname']) && (isset($_POST['lname']) && (isset($_POST['email']) && (isset($_POST['usn']) && (isset($_POST['schedule']) && (isset($_POST['year']) && (isset($_POST['strand']))))))))
{
$fname = $_POST['fname'];
$mname = $_POST['mname'];
$lname = $_POST['lname'];
$email = $_POST['email'];
$usn = $_POST['usn'];
$schedule = $_POST['schedule'];
$year = $_POST['year'];
$strand = $_POST['strand'];
}
if (isset ($_POST['DateHired']) && (isset($_POST['ResignationDate']) && (isset($_POST['EmployeeNo']))))
{
$DateHired = $_POST['DateHired'];
$ResignationDate = $_POST['ResignationDate'];
$EmployeeNo = $_POST['EmployeeNo'];
}
if (isset ($_POST['TimeLogID']) && (isset($_POST['EmployeeID']) && (isset($_POST['RecordDate']) && (isset($_POST['RecordTime']) && (isset($_POST['Type']) && (isset($_POST['ActualTime'])))))))
{
$TimeLogID = $_POST['TimeLogID'];
$EmployeeID = $_POST['EmployeeID'];
$RecordDate = $_POST['RecordDate'];
$RecordTime = $_POST['RecordTime'];
$Type = $_POST['Type'];
$ActualTime = $_POST['ActualTime'];
}

IIUC - simply filter your query by the specific EmployeeNo (or whatever identifier of web user) by passing as a parameter the value returned from posted HTML form. This requires you to change code order where you run your query after assigning $_POST values.
...
if (isset ($_POST['DateHired']) && (isset($_POST['ResignationDate']) && (isset($_POST['EmployeeNo']))))
{
$DateHired = $_POST['DateHired'];
$ResignationDate = $_POST['ResignationDate'];
$EmployeeNo = $_POST['EmployeeNo'];
}
...
$query= 'SELECT EmployeeNo, FirstName, MiddleName, LastName, DateHired, ResignationDate
FROM TA3.dbo.Employees
WHERE EmployeeNo = ?';
$statement = $conn->prepare($query);
$statement->bind_param(1, $EmployeeNo);
$statement->execute();
$res = $statement->fetchAll(PDO::FETCH_OBJ);
