First at all, I wouldn't use 1 or 2 for defining important informations. 
use something like

define('ORDER_GIFT', 1);
define('ORDER_PERSONAL',2);

If you want to check all values of your array you can use several 
foreach loops like


foreach ($_SESSION['life_coaching_order'] AS $coaching_product = $tmp_array)
{
 foreach ($tmp_array as $coaching_gift = $tmp_array2)
 {
   switch ($coaching_gift)
 case ORDER_GIFT: break;

 case ORDER_PERSONAL: break;
)
 } 
}



Personally I would prefer writing a class like

class Order
{
  private $product;
  private $gift;
  private $quantity;

  const ORDER_GIFT=1;
  const ORDER_PERSONAL=2;

 function getGift() {
   return $this - gift;
 }
}

using

$_SESSION['life_coaching_order'][] = new Order();

foreach ( $_SESSION['life_coaching_order'] as $order )
{
 switch ( $order - getGift() )

 case ORDER_GIFT: break;

 case ORDER_PERSONAL: break;
  
} 


I hope that will help you,

In this example $value would be an array. To test if it is a gift or not you
would do this from within the foreach loop:

//gift
if ( isset($value[1])  isset($value[1]['quantity']) )
{
  $gift_quantity = $value[1]['quantity'];
}

//personal use
if ( isset($value[2])  isset($value[2]['quantity']) )
{
  $personal_quantity = $value[2]['quantity'];

Technically the above IF's are optional, but they are proper syntax.

I don't know how you are with OOP, but you may have more luck using objects
instead of a complex array.

Re: [PHP] Array / form processing

2010-10-07 Thread Ron Piggott 

Many thanks, Chris.

I have one additional question about this shopping cart project.  I need
to make a submit button for the purpose of removing an item from the
shopping cart.

input type=submit name=submit value=Remove class=place_order/

What I am struggling with is to find an effective method for passing the
product serial number (auto_increment in the table it is stored in) so I
know which product the user is removing from their purchase.  Then I will
just unset the session variable that matches.

What are your suggestion(s)?

Thank you your help with my original question Chris.

Re: [PHP] Array / form processing

2010-10-07 Thread chris h 
input type=submit name=submit value=Remove class=place_order/

I don't know what the context is like, but you may be better off just using
an entire form here with hidden fields. i.e.

form target=... action=...
 input type=hidden name=submit value=Remove /
 input type=hidden name=product_so value=1234 /
 input type=submit value=Remove class=place_order/
/form


Without knowing what else is going on in your page, and how the request is
being handled on the server, it's kind of hard to give exact advice. :)

Sort of.

  $$key = $val;
echo $key . :  . $val . br;
 
if ( $val == Array ) {

I would prefer to use is_array() here:

if (is_array($val))

   $i=0;
 

At this point, you've just proved that $val is an array (whichever test you 
use!), so simply foreach it like one. I know you know how to do that as you did 
it with $_REQUEST above!

   foreach ($val) {
   echo $val[$i]br;
   $i++;
   }

foreach ($val as $option) {
   echo $optionbr /\n;
}

 
}
 }
 
 ?

Try this:

If you want the form to retain the values, try this:

You need to iterate that array, as that holds the values of everything

Think about it...

You would not ?php echo $_REQUEST; ? and expect to get the value of any form
field would you.  No, you wouldn't.

Given the following form...

form
Titleinput type=text name=title value= /br /
Subjectinput type=text name=subject value= /br /
input type=submit name=submit value=Send it! /
/form

on the processing page, I would access those variables by writing the following.

echo $_REQUEST['title'];
echo $_REQUEST['subject'];

With that said, going back to your issue, you would do this:

if ( $_REQUEST['painDesc']  count($_REQUEST['painDesc']) ) {
  foreach($_REQUEST['painDesc'] as $key = $val) {
echo {$key}:{$val}br /;
  }
}
