[SOLVED] limiting the loop

[almystersv]

Hi Guys,

 

I am creating a mock up of a stationary ordering system and have a side bar on main products page that shows a snippet of the shopping basket and i want it to show just the top three items in the basket.

 

Here is my code that displays the basket on my products page...

 

<?php
if (isset ($_SESSION['basket'])) 
{
foreach($_SESSION['basket'] as $key => $product)
{ ?>
  <tr>
    <td width="40%"><?php echo $_SESSION['basket'][$key]['productName']?></td>
    <td width="20%">£<?php echo $_SESSION['basket'][$key]['price']?></td>
	<td width="20%" align="center"><?php echo $_SESSION['basket'][$key]['quantity']?></td>
	<td><a href="removefrombasket.php?URN=<?php echo $product['URN']?>">[-]</a></td>
  </tr>
<?php } ?>
</table>
<?php }
else { ?>
No Products Chosen.
<?php }
?>

 

the reason for this is that i have limited space and at current everytime something is added it keeps displaying it on this page, understandably, but I would like to know how I can change it to show just 3.

 

Thanks

add a counter

 

<?php
if (isset ($_SESSION['basket'])) 
{
  $n = 0;
  foreach($_SESSION['basket'] as $key => $product)
  {
?>
  <tr>
    <td width="40%"><?php echo $_SESSION['basket'][$key]['productName']?></td>
    <td width="20%">£<?php echo $_SESSION['basket'][$key]['price']?></td>
	<td width="20%" align="center"><?php echo $_SESSION['basket'][$key]['quantity']?></td>
	<td><a href="removefrombasket.php?URN=<?php echo $product['URN']?>">[-]</a></td>
  </tr>
<?php
    $n++;
    if($n >= 3) break;
  }
?>
</table>
<?php
}
else { ?>
No Products Chosen.
<?php
}
?>

Superb, Thanks!

 

Any chance of adding a link that pops up when it goes over 3?!

 

So say 4 things are added, it will only show the top 3 but then a little link at the bottom will appear saying more...

 

Which when click will jst link to the basket page.

 

Thanks

in the if >= 3 statement, you can add more code before the break (like printing a more... link)

 

as far as sometimes showing 3, and other times showing all, i would setup a $limit variable in the session to help keep track of which version to show. Then change the if to:

if($limit && $n >= 3){....
