Can somebody help me?

Hello,

 

I am currently creating an online with good intergration for checkoing out, I have assigned variables that are placed into to hidden fields and sent to google, the problem arises when the loop kicks in, as it resets the variables and reassignes them to the old value rather than the next values,

 

// Print each item.
$total = 0; // Total cost of the order.
while ($row = mysql_fetch_array ($result)) {

	$count = $count+1;
	$subtotal = $_SESSION['cart'][$row['product_id']]['quantity'] * $_SESSION['cart'][$row['product_id']]['price'];
	$total += $subtotal;

	//setting table variables
	$catname = $row['category_name'];
	$prodname = $row['product_name'];
	$price = $_SESSION['cart'][$row['product_id']]['price'];
	$quantity = $_SESSION['cart'][$row['product_id']]['quantity'];

	// Print the row.
	echo "	<tr>
	<td align=\"left\" bgcolor=\"#cccccc\">{$row['category_name']}</td>
	<td align=\"left\" bgcolor=\"#cccccc\">{$row['product_name']}</td>
	<td align=\"right\" bgcolor=\"#cccccc\">£{$_SESSION['cart'][$row['product_id']]['price']}</td>
	<td align=\"center\" bgcolor=\"#cccccc\"><input type=\"text\" size=\"3\" name=\"qty[{$row['product_id']}]\" value=\"{$_SESSION['cart'][$row['product_id']]['quantity']}\" /></td>
	<td align=\"right\" bgcolor=\"#cccccc\">£" . number_format ($subtotal, 2) . "</td>
</tr>\n";
} // End of the WHILE loop.

mysql_close($dbc); // Close the database connection.

// close the table, and the form.
echo '	<tr>
	<td colspan="4" align="right"><b>Total:<b></td>
	<td align="right">£' . number_format ($total, 2) . '</td>
</tr>
</table><div align="center"><input type="submit" name="submit" value="Update My Cart" />	
<input type="hidden" name="submitted" value="TRUE" />
</form><br /><br />';
?>
<?php
} else {
echo '<p>Your cart is currently empty.</p>';
}	
?>
<?php
echo"<form id=\"googlecheckout\" method=\"POST\" action = \"https://checkout.google.com/api/checkout/v2/checkoutForm/Merchant/453070710704027\"
accept-charset=\"utf-8\">";
while ($count > 0)
{
echo"<input type=\"hidden\" name=\"item_description_$count\" value=\"$catname\" />
<input type=\"hidden\" name=\"item_name_$count\" value=\"$prodname\" />
<input type=\"hidden\" name=\"item_price_$count\" value=\"$price\" />
<input type=\"hidden\" name=\"item_quantity_$count\" value=\"$quantity\"/>
<input type=\"hidden\" name=\"item_currency_$count\" value=\"GBP\"/>";
$count --;
}
echo "<input type=\"image\" name=\"Google Checkout\" alt=\"Fast checkout through Google\"
src=\"http://checkout.google.com/buttons/checkout.gif?merchant_id=453070710704027&w=180&h=46&style=white&variant=text&loc=en_US\"
height=\"46\" width=\"180\"/>
</form>";

echo $row;
?>

Please some1 help me :-(

Try making the variables arrays, appending [$count] to the end.  This will prevent overwriting.  You will have to adjust your code whenever you access the data, however.

[s_ainley87]

Sorry I am really quite stupid when it comes to PHP, could you explain alittle more please?

 

[947740]

I have a quick question.  What is your original $count value?  I am not seeing a declaration for that value.

[s_ainley87]

the original value is

 

$count = $count+1;

 

 

[947740]

Don't you have to have something to add 1 to though?  Or is it just a theoretical value?

[s_ainley87]

I dont know what you mean sorry.

[947740]

My point is that there is not a value to $count, but you are adding 1 to it.  I think you have to make it soemthing like $count = 0, and then $count = $count+1.

 

I am having a hard time explaining this...maybe I am the one that is confused...

[Yesideez]

Just for info, $count=$count+1 can be replaced with $count++

[s_ainley87]

Yeah thanks not got to tidying yet,

 

what i am looking to do is ieterate through an array and pull the deatils from it, and add the deatils to hidden fields of a form...I need to iterate until all products in the session have been looked at.
