# Enbart en produkt i kundkorgen.

## #1 — Hesslow, 2001-08-06T15:43Z

Kunderna kan bara lägga till en produkt i kundkorgen, varför? Lägger man till fler, försvinner alla utom den senaste=(

Jag är "bara" designern, kan egentligen ingenting om PHP. Därför behöver jag veta vad som är fel, helst en fullfjädrad lösning. 

Vet inte vilken fil som problemet ligger i, gissar att det är denna.

```
<?
if ($HTTP_COOKIE_VARS["_webhallen"] != '') {
?>

<tr>
<td background="bilder/menybottom.gif"><img src="bilder/prick.gif" height="1" width="1"></td>
</tr>
<tr>
<td height="2" bgcolor="#FFFFFF"><img src="bilder/prick.gif" height="2" width="1"></td>
</tr>
<tr>
<td height="15" background="bilder/menytop.gif"><img src="bilder/varukorg.gif" height="6" width="52" hspace="10"></td>
</tr>
<tr>
<td background="bilder/menymiddle.gif" align="right">

<table cellpadding="0" cellspacing="5" border="0" width="132">
<tr>
<td>
<font face="verdana" size="1">

<?
$_products = explode ("&#0124;", $HTTP_COOKIE_VARS["_webhallen"]);
$_summa = 0;
foreach ($_products as $_product) {
  list ($_id2, $_beg, $_antal) = explode (":", $_product);
  if ($_beg == 1) {
    $_pris = ", beg";
  } elseif ($_beg == 2) {
    $_pris = ", nb";
  } else {
    $_pris = ", price";
  }
  $_SQLresult = mysql_query ("SELECT name, konsol, genre $_pris from spel WHERE id = '$_id2'"); 
  if (mysql_num_rows ($_SQLresult) > 0) {
    $_row = mysql_fetch_row($_SQLresult);
    $_summa = $_summa + $_row[3] * $_antal;
    echo "<a href='page.php?_id=$_id2'>$_row[0]</a> ";
    if ($_antal > 1) {
      echo $_antal . " st<br>";
    } else {
      echo "<br>";
    }
  }  
}

echo "<b>Summa: $_summa kr</b><br><br><a href='change_kundkorg.php?_konsol=$_konsol'>Ändra</a> &#0124; <b><a href='kassa.php?_konsol=$_konsol'>Gå till kassan</a>";
?>

</td>
</tr>
</table>

</td>
</tr>

Snabbt svar är önskvärt.

Min cookie efter 2 "köp" är:
2565%3A0%3A1 
vilket för mig ser ut som endast en produkt. Jag gissar därför att det är fel på den kod som sätter dina cookies.

## #4 — nicclas, 2001-08-06T16:32Z

Nej, det tror inte jag ;)

Var läggas produkt-id och beg/inte beg in? Var sätts cookien "\_webbhallen"?

Tror felet ligger i addproduct.php eller forward.php (troligen den första). Hur ser den ut?

Då du lagrar "alla" köp i en cookie, så verkar det ha bivit fel när du skall "appenda" data till den cookie som sattes för första "köpet". Denna kod ligger antagligen i addproduct.php. Kolla efter i den...

Snabb gissning:
Skall inte $webhallen vara $\_webbhallen på raden före // echo "fel";
