Shopping cart for ecommerce site

Hi all,

I have a small problem in a shopping cart for an ecommerce site.

I have a function in the shopping cart that add one unit if I make add to cart,
and to do an update of this quantity I have a list menu with only 20 numbers from where I can select the quantity.
Does anyone knows whow can I, instead of list menu with 20 numbers, place a text field where the user insert the quantity?

Thanks.
António



This is the code:

<?php $id=$row['itemId'];?>
<? //print "<input type=\"text\" name=\"qty'.$id.'\" value='.$qtd.' size=\"3\" maxlength=\"3\"
onChange='UpdateQty(this)'/>" ?>
<select name="<?php echo $row["itemId"]; ?>" onChange="UpdateQty(this)">
<?php

for($i = 1; $i <= 20; $i++)
{
echo "<option
";
if($row["qty"] == $i)
{
echo " SELECTED ";
}
echo ">" . $i . "</option>";
}
?>
</select>

 

<?php $id=$row['itemId'];?>
<? //print "<input type=\"text\" name=\"qty'.$id.'\" value='.$qtd.' size=\"3\" maxlength=\"3\" 
onChange='UpdateQty(this)'/>" ?>

<input type="text" name="<?php echo $row["itemId"]; ?>"  value="<?php echo $row["qty"]; ?>" onChange="UpdateQty(this)">

PHP:

You will need to do some validation & sanitisation of the input to this field though.......

 

Thanks for your fast reply.
I did the changes but in doesn´t update!
I think that I need to change my function UpdateQty, but I don’t know where…
Sorry for my low knowledge of PHP…
Can you help?

<script language="JavaScript">
<!--

function UpdateQty(item)
{
itemId = item.name;
newQty = item.options[item.selectedIndex].text;

document.location.href = 'cart.php?action=update_item&id='+itemId+'&qty='+newQty;
}
//-->
</script>

 

Problem solve!
No need to reply!
