OrderForm - How do I how only domains that do not have hosting packages with them?

[Nullified]

I am trying to build a function that only lists domains (on viewcart) that do not have a web hosting account setup with them. Maybe it's too late, but I am failing horribly:

{foreach key=num item=domain from=$domains}
{foreach key=num item=product from=$products}
{assign var=domainused value=false}
{if $domain.domain eq $product.domain}{assign var=domainused value=true}{/if}
		All my domains that do not have hosting accounts ordered with them will be listed here!
{/foreach}
{/foreach}

Took almost a day for me to figure this out but here is what I came up with just adding a simple smarty plugin that is basically a remake of assign and using twenty thousand loops and if statements:

 

function smarty_compiler_append($tag_attrs, &$compiler)
{
   $_params = $compiler->_parse_attrs($tag_attrs);

   if (!isset($_params['var'])) {
       $compiler->_syntax_error("assign: missing 'var' parameter", E_USER_WARNING);
       return;
   }

   if (!isset($_params['value'])) {
       $compiler->_syntax_error("assign: missing 'value' parameter", E_USER_WARNING);
       return;
   }

   return "\$this->append({$_params['var']}, {$_params['value']});";
}

{foreach key=num item=domain from=$domains}
{foreach key=num item=product from=$products}
	{if $domain.domain eq $product.domain}{append var=dused value=$domain.domain}{/if}
{/foreach}
{/foreach}
{foreach key=num item=domain from=$domains}
{assign var=hashosting value=false}
{foreach key=num item=domainsused from=$dused}
	{if $domainsused eq $domain.domain}{assign var=hashosting value=true}{/if}
{/foreach}
{if $hashosting eq false}

can't you just do something like this... would be alot easier.

{php}

# Check if domains in cart has hosting.

global $smarty;

$proddomain = array();

$products = $_SESSION['cart']['products'];

if ($products) {

foreach ($products as $product) {

$proddomain[] = $product['domain'];

}

}

$domains = $_SESSION['cart']['domains'];

if ($domains) {

foreach ($domains as $key => $domain) {

if (!in_array($domain['domain'],$proddomain)) {

$nohostingdomain = $domain['domain'];

break;

}

}

$smarty->assign('nohosting', $nohostingdomain);

}

{/php}

{if $nohosting}

<div class="infobox"><strong>You appear to have no hosting for your domain name <span class="textred">{$nohosting}</span></strong><br />To enable your domain name to work correctly and to appear on the internet, you need to have it hosted on a server.<br /><a href="cart.php"><strong>Click Here to Add hosting to your order</strong></a></div>

{/if}

Thanks for the guidance. I got your code to work with some slight mods (still using my smarty append plugin):

{php}
global $smarty;
$proddomains = array();
$products = $_SESSION['cart']['products'];
if ($products) {
foreach ($products as $product) {
	$proddomains[] = $product['domain'];
}
}
$unhostdomains = array();
$domains = $_SESSION['cart']['domains'];
if ($domains) {
foreach ($domains as $key => $domain) {
	if (!in_array($domain['domain'], $proddomains)) {
		$unhostdomains[] = $domain['domain'];
		$smarty->append('nohosting', $domain['domain']);
	}
}
}
{/php}

{foreach key=num item=domain from=$domains}
{foreach key=num item=unhosted from=$nohosting}
	{if $domain.domain eq $unhosted}
		<tr>
			<td align="left" class="service"><strong>Hosting Package:</strong> No hosting package has been selected<span class="links"><a href="{$smarty.server.PHP_SELF}?a=add" class="cartadd">[{$LANG.carthostingadd}]</a></span></td>
			<td class="spacerMiddle"></td>
			<td align="center"{if !$product.addons} rowspan="2"{/if}><strong>{$LANG.cartpricena}</strong></td>
		</tr>
		<tr><td align="center"></td><td class="spacerMiddle" height="15"></td><td align="center"></td></tr>
		<tr>
			<td align="left" class="service"><strong>Domain Name:</strong> {trim domain=$domain.domain} for {$domain.regperiod} {if $domain.regperiod eq 1}{$LANG.orderyear}{else}{$LANG.orderyears}{/if}<span class="links"><a href="#" onclick="removeItem('d','{$num}');return false" class="cartremove">[{$LANG.cartremove}]</a></span></td>
			<td class="spacerMiddle"></td>
			<td align="center" rowspan="2"><strong>{$domain.price}</strong></td>
		</tr>
		<tr>
			<td align="left" class="addon"><strong>Addons:</strong> {if $domain.dnsmanagement or $domain.emailforwarding or $domain.idprotection}{if $domain.dnsmanagement}{$LANG.domaindnsmanagement}{if $domain.emailforwarding or $domain.idprotection} & {/if}{/if}{if $domain.emailforwarding}{$LANG.domainemailforwarding}{if $domain.idprotection} & {/if}{/if}{if $domain.idprotection}{$LANG.domainidprotection}{/if}{else}No addon services have been selected{/if}<span class="links"><a href="{$smarty.server.PHP_SELF}?a=confdomains" class="cartedit">[{$LANG.cartreconfigure}]</a></span></td>
			<td class="spacerMiddle"></td>
		</tr>
		<tr><td align="right"><hr width="97%" /></td><td class="spacerMiddle"></td><td align="left"><hr width="96%" /></td></tr>
	{/if}
{/foreach}
{/foreach}

Bother versions work, but I have seen that it is ill advised to use php in the templates, so which one should I use?
