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.
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.
Here is the code of three forms as requested:
cart.php
<?php ob_start(); ?>
<?php session_start();?>
<?php include("includes/functions.php");?>
<?php error_rep(); ?>
<?php require_once("includes/connection.php");?>
<?php

if (isset($_POST['pid'])) {
$pid = $_POST['pid'];
$wasFound = false;
$i = 0;
// If the cart session variable is not set or cart array is empty
if (!isset($_SESSION["cart_array"]) || count($_SESSION["cart_array"]) < 1) {
// RUN IF THE CART IS EMPTY OR NOT SET
$_SESSION["cart_array"] = array(0 => array("item_id" => $pid, "quantity" => 1));
} else {
// RUN IF THE CART HAS AT LEAST ONE ITEM IN IT
foreach ($_SESSION["cart_array"] as $each_item) {
$i++;
while (list($key, $value) = each($each_item)) {
if ($key == "item_id" && $value == $pid) {
// That item is in cart already so let's adjust its quantity using array_splice()
array_splice($_SESSION["cart_array"], $i-1, 1,
array(array("item_id" => $pid, "quantity" => $each_item['quantity'] + 1)));
$wasFound = true;
} // close if condition
} // close while loop
} // close foreach loop
if ($wasFound == false) {
array_push($_SESSION["cart_array"], array("item_id" => $pid, "quantity" => 1));
}
}
redirect_to("cart.php");
exit();
}
?>
<?php
// Section 2 (if user chooses to empty their shopping cart)
if (isset($_GET['cmd']) && $_GET['cmd'] == "emptycart") {
unset($_SESSION["cart_array"]);
}

$quantity = $_POST['quantity'];

}
?>
<?php
