Text file? Checkboxes? Text file checkboxes?!??!

[Easter_Bunny]

Hi. I've got a problem(don't we all?):

I've got a shop where you store all your items as well as the prices in a text file. I got some help on displaying all the items in the shop next to checkboxes, but now I'm baffled by the next part. When you select the items you want and then submit, you should be shown a list of the items you selected(not all the items in the shop and also not nothing - this is what I've been getting)as well the total cost of it all.

The code I use to display all the items in the shop next to checkboxes looks like this:

	{
		print("<form method=post>");
		print("Select the items you want<br><br>");

	$f = file($afile);
	foreach ($f as $key=>$val)
	{
		$entry = explode(",",$val);
		foreach ($entry as $key2=>$val2)
		{
			$tmp=explode("-",$val2);
			$item = $tmp[0];
			$price = $tmp[1];
			if ($item)
			{
				print("<input type=checkbox name=$item> $item R
                ".number_format($price,2)."<br>"); 
			}
		}
	} 
	print("<input type=submit name=submit value=Submit>
				 <input type=hidden name=action value=checkout>
				 </form>");
}

Can someone please help me with the next part where you are shown what you've purchased and the total cost?

Thanks

First you need to post your form to an other page :

print("<form method=post action=\"ReceiveForm.php\">");

The in ReceiveForm.php you've got to see what has been checked
so you'll want to test all you $item

$TotalPrice = 0;
foreach ($f as $key=>$val)
{
  $entry = explode(",",$val);
  foreach ($entry as $key2=>$val2)
  {
    $tmp=explode("-",$val2);
    $item = $tmp[0];
    $price = $tmp[1];
    if ($item) {

     $TotalPrice += $price;
     // Your treatment for each item purchased

}
  }
}

Thanks for the reply.

I changed my script a bit to this:

		print("<form method=post>");
		print("You have selected the following<br><br>");

	$f = file($afile);
$totalprice = 0;
	foreach ($f as $key=>$val)
	{
		$entry = explode(",",$val);
		foreach ($entry as $key2=>$val2)
	  {
			$tmp=explode("-",$val2);
			$item = $tmp[0];
			$price = $tmp[1];
			if ($item)
			{
				$totalprice += $price;
				print("$item at a cost of R $price<br>");
			}
		}
		print("<br>Total cost : R $totalprice<br><br>");
		print("<a href=http://devin/custom.php?mode=shop&action=selectitems>Back</a><br>");
		print("<a href=http://devin/custom.php?mode=shop&action=checklogin>Back to start</a><br>");
		print("</form>");
	}
}

It still gives a complete list of all the items in the file as well as the total cost of all the items. It's supposed to only show what you selected.

Am I doing it right? I don't actualy want to use more than one page to do all of this. I just post it to the same page (am I saying this right?)

What am I doing wrong with my script? I'm completely clueless on this. I'm changing my avatar as soon as I post this.😃
