[PHP] beginner in PHP
Can someone tell me why this doesn't work?
The $mycart array is fine and the $catalog array is also fine but nothing
inside the if statement prints. I've tried other echo statements but nothing
prints at all.
while (list($key,$value) = each($mycart))
{
if ($value == $catalog[itemcd])
{
echo $catalog[unitprice];
}
}
Thanks
Phil

RE: [PHP] beginner in PHP
itemcd is an element of the array.. like this...
array ('itemcd' => 'book', 'itemdesc' => 'This book is great', 'unitprice'
=> '29.95');

Is itemcd a variable then it should be used as $itemcd?

Try this:
echo "$catalog[unitprice]";
in my experience I've only been able to use the echo() without the
quotation marks if I'm calling a function, for variables you need the
quotation marks.
Hope this helps.

Hi
itemcd and unitprice should be in quotes I think if they are keys in an
array.
$catalog["itemcd"]
$catalog["unitprice"]

Hi
Then I guess you will have to add some debug code
try this before the while loop and make sure your if ($value ==
$catalog["itemcd"]) will produce a match (and you do need the quotes really

echo "".print_r($catalogue)."".print_r($mycart)."";

RE: [PHP] beginner in PHP
Thanks Martin!! That really helped out a lot. And thanks to all who tried to
help me. I appreciate it!
I have one other question that is really not so much important as it is
annoying, but I can't figure it out myself.
I'm practicing with sessions. What I'm making..if you couldn't tell by the
array output from before...is a test shopping cart. Now the annoyance is
that when I click the checkout link it's just supposed to destroy the
session and reset everything to 0 including the shopping cart. And also if
an item is clicked, that item gets deleted. With both choices when I click
once the session does get destroyed, but everything stays on the page until
I refresh the page. I want the info to get reset when I click the link.
Here's the delete and checkout code...remember they both do actually work,
just not as I want. Any suggestions on how to make it refresh on a click
only?
/ DELETE SHOPPING CART ITEMS
function chout(){
session_destroy();
$mycart = array();
$cart_items = 0;
echo "Thank you for shopping!";
}
if ($action == delnow)
{
unset($mycart[$itemid]);
}
// END DELETE SHOPPING CART ITEMS
if ($action == checkout)
{
chout();
}

array output from before...is a test shopping cart. Now the
annoyance is
that when I click the checkout link it's just supposed to destroy
the
session and reset everything to 0 including the shopping cart. And
also if
an item is clicked, that item gets deleted. With both choices when I
click
once the session does get destroyed, but everything stays on the
page until
I refresh the page. I want the info to get reset when I click the
link.
Here's the delete and checkout code...remember they both do actually
work,
just not as I want. Any suggestions on how to make it refresh on a
click
only?
/ DELETE SHOPPING CART ITEMS
function chout(){
session_destroy();
$mycart = array();
$cart_items = 0;
echo "Thank you for shopping!";
}
if ($action == delnow)
{
unset($mycart[$itemid]);
}
// END DELETE SHOPPING CART ITEMS
if ($action == checkout)
{
chout();
}

here's the revised loop
$cat_cnt = count($catalog);
while (list($key,$value) = each($mycart))
{
for ($j = 0; $j < $cat_cnt; $j++)
if ($value == $catalog[$j]["itemcd"])
{
echo $catalog[$j]["unitprice"];
break;
}
}

Ah! $catalog is a 2D array - any your if statement is expecting a 1D
array...

Array ( [0] => gerainiums [1] => roses [2] => roses [3] => roses [4]
=>
roses [5] => roses )
1

Your output is different from the last print_r that Tom had me do. I
wonder
why that is

Hi
Then I guess you will have to add some debug code
try this before the while loop and make sure your if ($value ==
$catalog["itemcd"]) will produce a match (and you do need the quotes
really
:)
echo "".print_r($catalogue)."".print_r($mycart)."";

Try this...
function chout(){
global $mycart, $cart_items;
session_destroy();
unset ($mycart);
unset ($cart_items);
echo "Thank you for shopping!";
}
And if it works, read this:

RE: [PHP] beginner in PHP
So how do I affect the local copies of the variables. The global() doesn't
seem to work. Should I take everything out of the function and just use if
statements?

You're insetting the variables within the chout() function only This has no
effect on
the local copies as they are not in scope here. You have successfully
destroyed the
session so when you refresh they are unset.
What I do with sessions is keep them all within a session array so you can
then destroy
the session locally by unsetting that array. If I have a function that I
want to change session
variables at all I make it take the session in as a parameter and pass it
back as the return value.
