Quantity in Shopping Cart

[look4game]

I´m having a problem with a javascript code. The problem is: Whenever I add a product to the shopping cart it appears in a list which has a form called qtd that lets me choose which quantity of that product I want The problem is that if I do this, and press "Actualizar Quantidades" I get an error (no debug). Can anybody help me figure where it is? Here is the code:

<?

include("../fonte.php");

if (isset($func)) {
	switch ($func) {
		case "remover" :
			$SESSION["carrinho"]->remover($id);
			break;

	case "recalcular" :
		actualizar_qtd($HTTP_POST_VARS);
		break;
}

$SESSION["carrinho"]->limpar();
$SESSION["carrinho"]->calcular_total();
}

$qid = items_carrinho();

include("$CFG->dir_includes/topo.php");

?>
<script language="Javascript">
function frmsubmit(func) {
	frm = document.entryform;
	frm.func.value = func;
	frm.submit();
}	
</script>
<?
echo "

<form name='Carrinho' method='post' action='$EU'>
<input type='hidden' name='func' value=''>

<table class='Tabela' cellSpacing='2' cellpadding='2' width='100%' align='center' border='0'>
  <tr bgcolor='#ffffff'>
    <th height='20' width='20'><div align='center'></div></th>
    <th width='40'><div align='center'>Ref # </div></th>
    <th><div align='center'>Produto</div></th>
    <th width='60'><div align='center'>Preço</div></th>
    <th width='40'><div align='center'>Qtd</div></th>
    <th width='60'><div align='center'>Total</div></th>
  </tr>";

while ($prod = db_fetch_object($qid)) { 
	$quantidade = $SESSION["carrinho"]->items[$prod->id];
	$total = $prod->preco * $quantidade;

echo "

  <tr bgcolor='#eeeeee'>
  <input type='hidden' name='id[]' value='$prod->id'>
    <td><div align='center'><a title='Eliminar Produto' href='$EU?func=remover&id=$prod->id'><img src='$CFG->dir_imagens/Layout/Loja/Carrinho/Eliminar.gif' width='18' height='18' border='0'></div></a></td>
    <td><div align='center'>A0001</div></td>
    <td> $prod->nome</td>
    <td><div align='center'>€ $prod->preco</div></td>
    <td><div align='center'><input type='text' size='3' name='qtd[]' value='$quantidade'></div></td>
    <td><div align='center'>€ ";
	printf("%.2f", $total);
	echo "
	</div></td>
  </tr>";


}

echo "

  <tr bgcolor='#eeeeee'>
  	<td  height='20' colspan='5'> </td>
  	<td><div align='center'><strong>€ ";
  	printf("%.2f", $SESSION["carrinho"]->total);
  	echo "
	</strong></div></td> 
  </tr>
  <tr>
  	<td colspan='6' height='20'>"; ?>
	    <li><a href="javascript: frmsubmit('recalcular');">Actualizar Quantidades</a> 
	<? echo "</td>
  </tr>
  <tr>	
  	<td colspan='6' height='30'><div align='center'>
	<a href='$CFG->www_base'><img src='$CFG->dir_imagens/Layout/Loja/Carrinho/Voltar.gif' width='150' height='30' border='0'></a>
	<a href='comprar.php'><img src='$CFG->dir_imagens/Layout/Loja/Carrinho/Finalizar.gif' width='149' height='30' border='0'></a>
	</div></td>
  </tr>		  

</table>

</form>";


include("$CFG->dir_includes/fundo.php");


function actualizar_qtd(&$form) {

global $SESSION;

foreach ($form["id"] as $i => $idproduto) {
	$quantidade = $form["qtd"][$i];
	$SESSION["carrinho"]->set($idproduto, $quantidade);
}
}

?>

Thank You

i think you are going to want to use
<a href="#" onclick="frmsubmit('recalcular')">Actualizar Quantidades</a>
or
<a href="javascript:frmsubmit('recalcular')">Actualizar Quantidades</a>

see if that fixes the error.

Thank you drew010, however, it didn´t work. It still gives me the same "Error on Page" in IE taskbar when I press the "Actualizar Quantidades" link. 🙁

i tested the other javascript code in there, changing the field name of course, and it worked fine. it may be other code or something to do with the form field. if you use internet explorer you can turn script debugging on in the advanced tab of the internet options. uncheck disable script debugging. if you have mozilla you can use the script debugger by going into tools->web development.

Ok, in IE I get this error:

Line: 431
Char: 2
Erro: 'frm.func' is null or not an object
Code: 0

...and in Firefox I get the following message when I use the Javascript Console:

ERROR: frm has no properties

Any idea on where can be the problem?

Also, thank you for the time spent helping me 😉

[drew010]

if that is the error replace
<script language="Javascript">
function frmsubmit(func) {
frm = document.entryform;
frm.func.value = func;
frm.submit();
}

</script>
with
<script language="Javascript">
function frmsubmit(func) {
document.entryform.func.value = func;
document.entryform.submit();
}

</script>

Now I get this error in IE:

'document.entryform.func' is null or not an object

and in FireFox:

document.entryform has no properties

🙁

[drew010]

looking at
<form name='Carrinho' method='post' action='$EU'>
i think you should use
document.forms.Carrinho.* for your objects.

Thank you very much drew010.

The problem was there, where you said. The form name should be 'entryform' and not Carrinho.

Thank you once again for the help 😉
