Passing variables to more than one PHP

[low-rider]

hi,

 

im working on creating an online shopping website and wanna know if i can pass the same variable to more than one php?

 

for example when the user selects products(products.php), they get printed on the next page where they select delivery type and address(checkout.php), after that i need to pass the same variable to the overview page where the user can see what he/she have ordered, where it is being dispatched to, the cost and the payment details!!

 

im using $_GET['my var'] method at the moment and have action="checkout.php" in my products.php!

 

and finally i want to do a client side check on whether any items have  been selected when the user clicks on "continue button".

 

thank you very much!

The best use of passing these variables I've seen is in use by osCommerce.  The variables for each module are kept in one file and called when needed.  You can use $global if your server allows it.

 

It seems that it would be best to register the sessionID and contain the products within a variable specifically assigned to that sessionID called from a main page with all of your cart variables.

You can either place the variables within the $_SESSION array on products.php and collect them again on checkout.php and so on, or, place the values into a hidden field and submit them to the next page.

i solved the first problem with using $_SESSION, so thanks very much for that!

 

another problem i have is when the user selects products! this is done by a checkbox and the quantitiy is done by a text box!

 

now, whenever "contuinue" button is clicked the user is take to the checkout page....what i want to is to u deny him access to the checkout until he has selected an item!!!

 

i want this to be done at the client level not server!! can any one help me???

whatever i do i cant get any of the variables in my session to print!

 

is it supposed to be <? echo $_SESSION['var']; ?>

 

i really need help please!!!!

[low-rider]

anyone???

[low-rider]

can someone confirm that i have done this correctly??

 

in my products.php i have got this...

 

session_start();

$_SESSION['BagName'] = $BagName;

$_SESSION['BallName'] = $BallName;

$_SESSION['HatName'] = $HatName;

$_SESSION['QBag'] = $QBag;

$_SESSION['QHat'] = $QHat;

$_SESSION['QBall'] = $QBall;

 

 

and in my overview i have this.....

 

session_start();

 

$BagName = $_SESSION["BagName"];

$BallName = $_SESSION["BallName"];

$HatName = $_SESSION['HatName'];

$QHat = $_SESSION['QHat'];

$QBag = $_SESSION['QBag'];

$QBall = $_SESSION['QBall'];

 

 

but when i try to echo something in overview it doesnt print!

 

what am i doing wrong?

I like to use this to decipher $_SESSION

 

<?php

echo "<PRE>";
print_r ($_SESSION);
echo "</PRE>";

?>

 

Put those three lines somewhere in your page and you should get a nice print out of what is in $_SESSION.
