[PHP] Silly varible question

2006-07-13 Thread Ed Curtis 

 I know this is probably simple as all get out but it's early and I can't
find an answer anywhere after searching for a while


 I need to assign a number to a variable and then use that variable in a
session to store an array. It's for a shopping cart system I'm building.

What I've got is:

$count = 1; //First item in the cart passed from form to form

$item = array();

$item[] = $_POST['phone'];
$item[] = $_POST['category'];
$item[]  = $_POST['copy'];
$item[] = $_POST['pic_style'];
$item[] = $cost;
$item[] = $image;

session_register('item');

In the session the item is known as 'item'. What I need for it to be is
'item1' so when the customer chooses another product I can increase $count
by 1 and have the next array with values stored as 'item2'.

Thanks for any help,

Ed

Why not just have another array...

$bag = array();
$item[] 

array_push($bag, $item);

then store the bag in the session.
so, you would have count($bag) items in your shopping cart, and you 
would be able to easily access them.

Just a thought, instead of munging variable names.

use the $_SESSION super global instead of using session_register()
(read the manual for the fine print regarding $_SESSION and why
session_register() is no longer recommended)

e.g.:

function addItemToBag($item)
{
if (!isset($_SESSION['bag'])) $_SESSION['bag'] = array();
$_SESSION['bag'][] = $item;
}


 session_register('item');

 In the session the item is known as 'item'. What I need for it to be is
 'item1' so when the customer chooses another product I can increase
 $count
 by 1 and have the next array with values stored as 'item2'.

First off, don't use session_register, use the $_SESSION superglobal
array, that way you can create:




$_SESSION['count'] = 1

and increment like so:

$_SESSION['count']++

then  you can create the cart like so:

$item{$_SESSION['count']} = array();

does this make sense. Maybe not, but then again I've had far too much
coffee. Make sense to the php gurus out there?

 $item = array();
 
 $item[] = $_POST['phone'];
 $item[] = $_POST['category'];
 $item[]  = $_POST['copy'];

 In the session the item is known as 'item'. What I need for it to be
 is 'item1' so when the customer chooses another product I can
 increase $count by 1 and have the next array with values stored as
 'item2'. 

Just make $item a 2-dimensional array, with the first diemnsion addressed by 
$count; so:

  $item[$count][] = $_POST['phone'];
  $item[$count][] = $_POST['category'];
  $item[$count][] = $_POST['copy'];
  $item[$count][] = $_POST['pic_style'];
  $item[$count][] = $cost;
  $item[$count][] = $image;

  $count += 1;

  $item[$count][] = ...;
  $item[$count][] = ...;
  // etc.

Incorporating the (good) advice to use $_SESSION, this becomes:

  $_SESSION['item'][$count][] = $_POST['phone'];
  $_SESSION['item'][$count][] = $_POST['category'];
  $_SESSION['item'][$count][] = $_POST['copy'];
  $_SESSION['item'][$count][] = $_POST['pic_style'];
  $_SESSION['item'][$count][] = $cost;
  $_SESSION['item'][$count][] = $image;

  $count += 1;

  $_SESSION['item'][$count][] = ...;
  $_SESSION['item'][$count][] = ...;
  // etc.


Personally, I'd be inclined to use string indexes that indicate what's in each 
element, to avoid having to remember somehow which numeric index corresponds to 
which attribute; so:

  $_SESSION['item'][$count]['phone'] = $_POST['phone'];
  $_SESSION['item'][$count]['category'] = $_POST['category'];
  $_SESSION['item'][$count]['copy'] = $_POST['copy'];
  $_SESSION['item'][$count]['pic_style'] = $_POST['pic_style'];
  $_SESSION['item'][$count]['cost'] = $cost;
  $_SESSION['item'][$count]['image'] = $image;

  $count += 1;

  $_SESSION['item'][$count]['phone'] = ...;
  $_SESSION['item'][$count]['category'] = ...;
  // etc.

HTH


Cheers!

 Thanks for all the help guys. I now have a better understanding of multi
dimensional arrays and can use it for what I'm trying to accomplish. This
list is the greatest!!

yeah we rule (the land of goblins, fairies and helpless little leprecauns) ;-)
