There's no hidden parameter feature reference. The issue you have is a very common one among new developers, and that's knowing the difference between a function reference, and executing a function. function myFunction(){ //do stuff } thing.addEventListener('click', myFunction ); //<- pass a reference to myFunction thing.addEventListener('click', myFunction() ); //<- execute myFunction now, pass it's return value. addEventListener wants a callback function, which needs to be passed as a function reference. To do that, you only supply the name of the function (or an inline anonymous function). Adding the parenthesis after the function name causes that function to be executed rather than referenced. When you're passing a function reference, you cannot pass any parameters along with that reference, which is what you were trying to do. In order to supply parameters, you need to use the anonymous inline function as a wrapper. The anonymous function is passed as the real event handler callback, and when the event occurs and the anonymous function is executed, it in turn executes your desired event handler with the proper parameters.1 point

I was offering up a method rather than a spoonfed solution. This is a fuller solution incorporating the dates <?php $duration = 45; $cleanup = 0; $start = "10:00"; $end = "15:15"; ################################################################################ # Default week commence date # ################################################################################ $d1 = new DateTime(); if ($d1->format('w') <> 1) { $d1->modify('last monday'); } $wkcomm = $_GET['week'] ?? $d1->format('Y-m-d'); $d1 = new DateTime($wkcomm); $week1 = $d1->sub(new DateInterval('P7D'))->format('Y-m-d'); $week2 = $d1->add(new DateInterval('P14D'))->format('Y-m-d'); function timeslots($duration, $cleanup, $start, $end) { $start = new DateTime($start); $end = new DateTime($end); $duration += $cleanup; $interval = new DateInterval("PT".$duration."M"); return new DatePeriod($start, $interval, $end); } function daysOfWeek($comm) { $d1 = new DateTime($comm); return new DatePeriod($d1, new DateInterval('P1D'), 6); } ?> <!DOCTYPE html> <html lang="en"> <head> <meta http-equiv="Content-Type" content="text/html" charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <script src="https://code.jquery.com/jquery-3.6.0.min.js"></script> <title>Tehnički pregled</title> <script type='text/javascript'> $(function() { // when page has loaded $(".tslot").click(function() { // define click event listener $("#tVreme").val( $(this).data("timeslot") ) }) }) </script> <style type='text/css'> td, th { padding: 4px; text-align: center; } th { background-color: black; color: white; } </style> </head> <body> <section class="header"> <div class="navbar"> <div class="logo"> <img src="images/logo.png"> <span>Tehnički pregled</span> </div> <div class="nav-links" id="navLinks"> <ul> <li><a aria-current="page" href="index.php">Naslovna</a></li> <li><a href="galerija.php">Galerija</a></li> </ul> </div> </div> <div class="headline"> <h1>Tehnički pregled</h1> <p>Odaberite termin i zakažite tehnički pregled svog vozila brzo i jednostavno na našem sajtu.</p> <a href="#termin" class="btn">Zakažite termin</a> </div> </section> <div id="myModal" class="modal"> <div class="login-box"> <p>Zakazivanje termina</p> <form method="POST"> <div class="user-box"> <input name="tIme" type="text" required="Please"> <label>Ime</label> </div> <div class="user-box"> <input name="tPrezime" type="text" required> <label>Prezime</label> </div> <div class="user-box"> <input name="tTelefon" type="text" required> <label>Broj telefona</label> </div> <div class="user-box"> <input name="tVreme" id="tVreme" type="text" required readonly> <label>Datum i vrijeme</label> </div> <br> <input type='submit' value='POŠALJI'> </form> </div> </div> <section class="content" id="termin"> <br><br> <a href='?week=<?=$week1?>'>Previous Week</a>   <a href='?week=<?=$week2?>'>Next Week</a> <br><br> <table> <?php #################################################################### # BUILD THE TABLE OF TIMESLOTS # #################################################################### $days = daysOfWeek($wkcomm); $times = timeslots($duration, $cleanup, $start, $end); $today = new DateTime(); // table headings echo "<tr>"; foreach ($days as $d) { echo '<th>' . $d->format('l<\b\r>d M Y') .

Add some extra checks in to prevent the rendering of dates in the table if they are in the past. This should work: <section class="content" id="termin"> <?php $dt = new DateTime; $thisWeek = $dt->format('W'); $thisYear = $dt->format('o'); if (isset($_GET['year']) && $_GET['year'] >= $thisYear && isset($_GET['week']) && $_GET['week'] >= $thisWeek ) { $dt->setISODate($_GET['year'], $_GET['week']); } else { $dt->setISODate($dt->format('o'), $dt->format('W')); } $year = $dt->format('o'); $week = $dt->format('W'); ?>1 point
