[Typo3-shop] Feature List

[Franz Holzinger]

Hi Volker,

thanks for your advice. However I will need a much more complicated 
function for calculating the price. I have it working already under 
http://fholzinger.com/typo3/index.php?id=34. But it is hardcoded and I 
want to integrate it in a user friendly way into the next version of the 
shop. Even I need a function for the payment (Nachnahme).
Here it is hardcoded, where the total number (total_anzahl) should 
depend on an article type. All articles of the same type will get an 
extra price calculation. How could this be made user friendly for the 
maintainer of the shop?

$ueberweisungspreis = 0;
$nachnahme = strVal($this->basketExtra["payment."]["title"]);
if (strstr($nachnahme, "Nachnahme"))
	{
	if ($this->total_anzahl >= 1 && $this->total_anzahl <= 5)
		{
			$ueberweisungspreis = 4;
		}
	else if ($this->total_anzahl >= 6 && $this->total_anzahl <= 20)
		{
			$ueberweisungspreis = 5.80;
		}
	if ($this->total_anzahl >= 21 && $this->total_anzahl <= 50)
		{
			$ueberweisungspreis = 7.90;
		}
	}

	$this->calculatedSums_tax["payment"] = $ueberweisungspreis;

Here the price calculation:

function GetCalculatedData(&$preis, &$anzahl)
{
	$this->calculatedSums_tax["goodstotal"] = 0;
	$preistotal = array();
	$this->total_anzahl = 0;

	for ($j=0; $j<2; $j++)
	{
	    $preistotal [$j] = 0;
	    $akt_preis = array ( array( "1" => 4.99, "2" => 8.99, "5" => 19.99),
	                         array( "1" => 6.99, "2" => 13.98, "5" => 29.99 
) );
	    $ges_anzahl = 0;

	for ($i=1;$i<11;$i++)
	{
		if (($anzahl[$i] > 0) && ($preis[$i] == $akt_preis[$j]["1"]))
		{
			$ges_anzahl += $anzahl[$i];
		}
	}
	$dum_anzahl = $ges_anzahl;

	$preistotal [$j] = 0;

	while ($dum_anzahl > 5)
	{
		$dum_anzahl -= 5;
		$preistotal [$j] += $akt_preis[$j]["5"] ;
	}

	while ($dum_anzahl > 2)
	{
		$dum_anzahl -= 2;
		$preistotal [$j] += $akt_preis[$j]["2"] ;
	}

	while ($dum_anzahl > 0)
	{
		$dum_anzahl -= 1;
		$preistotal [$j] += $akt_preis[$j]["1"] ;
	}

	$this->total_anzahl += $ges_anzahl;
}

$this->calculatedSums_tax["goodstotal"] = $preistotal [0] + $preistotal [1];
$this->calculatedSums_no_tax["goodstotal"] = 
$this->calculatedSums_tax["goodstotal"];

$this->calculatedSums_tax["total"] = 
$this->calculatedSums_tax["goodstotal"];

$this->calculatedSums_tax["payment"] = 0;

$this->versandpreis = 0;

if ($this->total_anzahl <= 5)
{
	$this->versandpreis = 2.5;
}
else if ($this->total_anzahl <= 20)
{
	$this->versandpreis = 5;
}
else if ($this->total_anzahl <= 50)
{
	$this->versandpreis = 10;
}

$this->basketExtra["shipping"] = $this->versandpreis;
}
