PHP - Header Glitch (or Is It?)

I have an issue with a form where people choose from several classes, and how many people they're enrolling. If they choose the first class, select the number of students and hit submit, it is supposed to carry the number of students to the 2nd page where a variable is created for it:
$qty = $_POST['participantqty'];

It works if they pick the first class and choose a number of students.
It works if they pick the first class and another, plus the number of students for each.

But if they choose any one class except the first one (and only that class), choose their number of students and submit...
This is when it doesn't carry the number forward...

It also glitches when they select two classes that don't include the first class. It carries the number of students for one, but not the other.

qty_insert and qty_total on page two are where the data dissappears. I'm assuming it has something to do with the array, but I'm in a little over my head.

On the second page, I added in print_r($myarray); and it shows the variable is passing to the second page.

page one:
Code: [Select]

<form method="post" action="register2.php">

 <? //output each row

  while ($c_row = mysql_fetch_array($result_all_events)){
$display = date("F j", strtotime($c_row['workshop_date'])) ;
$i++;
//date('d m y', strtotime($mysql_date));


    ?>
 
<input type="checkbox" name="workshop_id[]" value="<?= $c_row['workshop_id'] ?>" /> <?= $c_row['workshop_title'] ?> </td><td><?= $c_row['workshop_date'] ?></td><td><select name="participantqty[]" id="" class="">
<option value="">select</option>
  <option value="1">1</option>
  <option value="2">2</option>
  <option value="3">3</option>
  <option value="4">4</option>
  <option value="5">5</option>
  <option value="6">6</option>
  <option value="7">7</option>
  <option value="8">8</option>
  <option value="10">9</option>
  <option value="10">10</option>
</select>
$ <?= $c_row['workshop_price'] ?></td></tr><tr><td colspan=3><hr></td></tr>


  <?

  } //end while
  ?>

<input type="submit" value="Submit" class="buttontype">


and on page two where it totals things up:

Code: [Select]
<form method="post" action="register3.php">

   echo htmlentities($row['comment'], ENT_QUOTES, "UTF-8");
 echo "<p>";
}
?>
thats my echo comment code. would it ahve anything to do with that?

Hello everyone, I'm just starting out with PHP as I need to create an online bookstore for a school project. I'm working by a magazine which should teach you exactly how to do this using PHP, but I've had a bunch of problems with the code they use and I don't really know what's going on. Anyway, this looks really simple and basically  what it does is allows you to post a comment on a book, then returns you to the book's page. Problem is, I'm getting the Header may not contain more than a single header, new line detected. error and I can't figure out why. I've tried researching into the matter but all the cases I found had to do with returning to an url, which is not my case.

Anyway, here's the snippet of code:

The form:

Code: [Select]
<div style="width:400px; border:1px solid #ffffff; background-color:#F9F1E7; padding:5px">
<b>Adauga opinia ta:</b>
<hr size="1">
<form action="adauga_comentariu.php" method="POST">
Nume: <input type="text" name="nume_utilizator"><br><br>
Email: <input type="text" name="adresa_email"><br><br>
Comentariu: <br> <textarea name="comentariu" cols="45"></textarea><br><br>
<input type="hidden" name="id_carte" value="<?=id_carte?>">
<center><input type="submit" value="Adauga"</center>
</form>
</div>
The script adaugare_comentariu.php:


Code: [Select]
<?php
ob_start();
include("conectare.php");
$numeFaraTags=strip_tags($_POST['nume_utilizator']);
$emailFaraTags=strip_tags($_POST['adresa_email']);
$comentariuFaraTags=strip_tags($_POST['comentariu']);
$sql="insert into comentarii (id_carte, nume_utilizator, adresa_email, comentariu) values(".$_POST['id_carte'].", '".$numeFaraTags."','".$emailFaraTags."','".$comentariuFaraTags."')";
mysql_query($sql);
$inapoi="carte.php?id_carte=".$_POST['id_carte'];
header("location:urldecode($inapoi)");
ob_end_flush();
?>
conectare.php connects to the mysql database. $inapoi is the variable which returns the user to carte.php (the book he posted a comment on), where id_carte is the book's unique id. I'm getting Header may not contain more than a single header, new line detected on line ten, which is the header line.

Can anyone help me? I've been stumped on this for a few days now and I've just let it pass and started working on other bits, but it's bugging me too much and I'd like to fix it.

How do I get this to put in the pilotID?

Code: [Select]
header("Location: logbook.php?id=" . $pilotid);
Thanks!
