Addon Stoped Working After Upgrade To 4.5.2.sp2 - Undefined Index: Cart

Store Builder Questions
1

Hi, I just did test upgrade from 4.3.9 to 4.5.2.SP2 and one of the addons stopped working - it shows "Undefined index: cart, Error at app/addons/qty_minimums/func.php, line: 23".

The addon page: http://forum.cs-cart.com/topic/21933-qty-minimums-addon-satisfy-minimum-quantities-with-product-options/

Below is the func.php file, and separately line 23:

foreach ($_SESSION['cart']['products'] as $k => $v) {

<?php

if ( !defined(‘AREA’) ) { die(‘Access denied’); }


/** [HOOKS] **/


function fn_qty_minimums_check_amount_in_stock (&$product_id, &$amount, &$product_options, &$cart_id, &$is_edp, &$original_amount, &$min_qty)

{

$_SESSION[‘temp_amount’] = $amount;


if ($_REQUEST['dispatch'] == 'checkout.update') {

	$new_amount = $amount;
	foreach ($_REQUEST['cart_products'] as $k => $v) {
		if (($v['product_id'] == $product_id) && ($k != $cart_id)) {
			$new_amount += $v['amount'];
		}
	}

} else {

	$new_amount = $amount;
	foreach ($_SESSION['cart']['products'] as $k => $v) {
		if (($v['product_id'] == $product_id) && ($k != $cart_id)) {
			$new_amount += $v['amount'];
		}
	}
}

if ($new_amount >= $min_qty) {
	$min_qty = $amount;
}



}


function fn_qty_minimums_check_amount_in_stock_minimum (&$product_id, &$amount, &$product_options, &$cart_id, &$is_edp, &$original_amount, &$min_qty)

{

$_SESSION[‘notifications’] = fn_array_unique($_SESSION[‘notifications’]);

if ($_REQUEST[‘dispatch’] == ‘checkout.place_order’) {

$min_qty = 0;

} else {

$min_qty = $_SESSION[‘temp_amount’];

}

}


/** [/HOOKS] **/


?>

Can you help me?

Please try:

#replace

$_SESSION['cart']

#with

Tygh::$app['session']['cart']

Please try:

#replace

$_SESSION['cart']

#with

Tygh::$app['session']['cart']

I tried and now it shows "Invalid argument supplied for foreach()"

Below the line 23 after replace:

foreach (Tygh::$app['session']['cart']['products'] as $k => $v) {

Please try 

$cart_products = Tygh::$app['session']['cart']['products'];
foreach ($cart_products as $k => $v) {
5

Please try 

$cart_products = Tygh::$app['session']['cart']['products'];
foreach ($cart_products as $k => $v) {

Unfortunately still "Invalid argument supplied for foreach()"

Please try

if (!empty($_SESSION['cart']) && !empty($_SESSION['cart']['products'])) {
  foreach ($_SESSION['cart']['products'] as $k => $v) {
    if (($v['product_id'] == $product_id) && ($k != $cart_id)) {
      $new_amount += $v['amount'];
    }
  } 
}

$cart = Tygh::$app['session']['cart'];
if(!empty($cart['products'])){
	foreach ($cart['products'] as $k => $v) {
		if (($v['product_id'] == $product_id) && ($k != $cart_id)) {
			$new_amount += $v['amount'];
		}
	}
}

      $new_amount += $v['amount'];
    }
  } 
}

Now it doesn't show any error, but the addon doesn't work.

Thank you a lot! That was it, actually didn't need to change the func.php after core modification.

$cart = Tygh::$app['session']['cart'];

Actually the old style still also works
