[Diether]

Hi guys good day, im a student and i want to practice my php skills, i have a big problem in arrays that i cant solve almost a week so i decided to attach the php files as well as its database.pls help me so that i can study this later. i'm really having a hard time in arrays. please help me so that i can move on.
There are 3 most important forms in my php files.
1. index.php
2.product.php
3. cart.php

Here is my screenshot of what i want to do in cart.php. i want to include the unit price and the sumofprice in my array as indicated in my screenshot so that i can include this information in a session variable later on.

How is the array being generated?

Post the relevant code to this thread.

array masters.. please help me to solve my problem

[Barand]

It would make your life easier if you you made the $pid the key of your session cart array

 

eg

 

$_SESSION['cart-array'][$pid]['quantity'] = 1;
