Shopping cart display problem

[_chester]

Hello everyone, I'm working on an online bookstore and I'm having some problems with the shopping cart section.

On the book page I have the following code, which is supposed to gather information like book title, author and price and send it to the shopping cart:

<form action="cos.php?actiune=adauga" method="post">
								<input type="hidden" name="id_carte" value="<?=$id_carte?>">
								<input type="hidden" name="titlu" value="<?=$rowCarte['titlu']?>">
								<input type="hidden" name="autor" value="<?=$rowCarte['nume_autor']?>">
								<input type="hidden" name="pret" value="<?=$rowCarte['pret']?>">
								<input type="submit" value="Cumpara acum!">
							</form>

Cart.php looks like this:

<?php
session_start();
include("conectare.php");
include("pagetop.php");
include("meniu.php");
$actiune=$_GET['actiune'];
if(isset($_GET['actiune']) && $_GET['actiune']=="adauga")
{
	$_SESSION['id_carte'][]=$_POST['id_carte'];
	$_SESSION['nr_buc'][]=1;
	$_SESSION['pret'][]=$_POST['pret'];
	$_SESSION['titlu'][]=$_POST['titlu'];
	$_SESSION['nume_autor'][]=$_POST['nume_autor'];
}
if(isset($_GET['actiune']) && $_GET['actiune']=="modifica")
{
	for($i=0; $i<count($_SESSION['id_carte']); $i++)
	{
		$_SESSION['nr_buc'][$i]=$_POST['noulNrBuc'][$i];
	}
}
?>
<td align="top">
	<h1>Cosul de cumparaturi</h1>
	<form action="cos.php?actiune=modifica" method="post">
		<table border="1" cellspacing="0" cellpadding="4">
			<tr bgcolor="#F9F1E7">
				<td><b>Nr. Buc</b></td>
				<td><b>Carte</b></td>
				<td><b>Pret</b></td>
				<td><b>Total</b></td>
			</tr>
<?php
for($i=0; $i<count($_SESSION['id_carte']); $i++)
{
	if($_SESSION['nr_buc'][$i] !=0)
	{
	print '<tr><td><input type="text" name="noulNrBuc['.$i.']" size="1" value="'.$_SESSION['nr_buc'][$i].'"></td>
	<td>'.$_SESSION['titlu'][$i].' de '.$_SESSION['nume_autor'][$i].' </td>
	<td align="right">'.$_SESSION['pret'][$i].' lei </td>
	<td align="right">'.($_SESSION['pret'][$i] * $_SESSION['nr_buc'][$i]).' lei </td>
	</tr>';
	$totalGeneral=$totalGeneral + ($_SESSION['pret'][$i] * $_SESSION['nr_buc'][$i]);
} 
}
print '<tr><td align="right" colspan="3"> Total in cos </td><td align="right">'.$totalGeneral.' lei </td></tr>';
?>
</table>
<input type="submit" value="Modifica"><br><br>
Introduceti 0 pentru cartile ce doriti sa le scoateti din cos!
<h1>Continuare</h1>
<table>
	<tr>
		<td width="200" align="center"><img src="cos.jpg"><a href="index1.php">Continua cumparaturile</a></td>
		<td width="200" align="center"><img src="casa.jpg"><a href="casa.php">Mergi la casa</a></td>
	</tr>
</table>
</td>
<?php
include("page_bottom.php");
?>

My problem is every time I add a book to the cart, nothing is updated except for the quantity, so I have no author, title or price info, like so:

I'm just starting php coding and I can't figure out what's going on. Anyone willing to lend a helping hand? :shy:

I've used var_dump and it displays the following:

array(5) { ["id_carte"]=> array(1) { [0]=> string(1) "3" } ["nr_buc"]=> array(1) { [0]=> int(1) } ["pret"]=> array(1) { [0]=> string(0) "" } ["titlu"]=> array(1) { [0]=> string(0) "" } ["nume_autor"]=> array(1) { [0]=> NULL } }

So the session isn't getting any info except quantity and book id.

That's just the Buy Now button, which is sending all the info to the shopping cart. Problem is, when I look at it with View Source, only id_carte (book id) has a correct value assigned to it, the others (titlu-title, autor-author, pret-price) have blank values.

$resursa=mysql_query($sql);
$row=mysql_fetch_array($resursa);

	?>

You're right, I should have included the whole thing. Now that I look at it, I have no idea what $rowCarte is or if it is even defined. $id_carte is the only one being received, perhaps because it has nothing to do with $rowCarte?

display_errors was turned off, I turned it back on and this is what I'm getting:

Notice: Undefined index: nume_autor in C:\xampp\htdocs\cos.php on line 13
Notice: Undefined variable: totalGeneral in C:\xampp\htdocs\cos.php on line 44
and a whole bunch of
Notice: Undefined variable: rowCarte in C:\xampp\htdocs\carte.php on lines 33, 35 and 49.
