When adding an item to the shopping cart, we are receiving the following error log:

[07-Jan-2021 19:10:14 America/Chicago] Request URI: /index.php?main_page=shopping_cart, IP address: xxxxx
#1  shoppingCart->calculate() called at [/includes/classes/shopping_cart.php:1362]
#2  shoppingCart->show_total() called at [/includes/modules/pages/shopping_cart/header_php.php:45]
#3  require(/includes/modules/pages/shopping_cart/header_php.php) called at [/index.php:35]
--> PHP Warning: A non-numeric value encountered in /includes/classes/shopping_cart.php on line 737.

When clicking on the item in the cart, once added, it brings the main page up and not the item in the cart

I am at a loss of wheat to look for...


** Moderator's note: This is fixed in 1.5.7c by changes to includes/functions/functions_prices.php. See

Not urgent. I've seen this a few times. I think I already have a fix ...

Excellent. ...and of course you do ;)
Standing by.

I should clarify:
This part, the warning, is what I meant is "not urgent":

PHP Warning: A non-numeric value encountered in /includes/classes/shopping_cart.php on line 737.

And, I'm pretty sure it's only related to virtual products or free-shipping products.


I think that's unrelated to your other issue of "When clicking on the item in the cart, once added, it brings the main page up and not the item in the cart".

Can you explain what steps would need to be taken to recreate this scenario on a fresh new cart?

All items on the site are free shipping; www.needtoorder.com

Add any item to the cart, then from the shopping cart, click on an item in the cart, it brings you back to the main page of the website.

That seems to be something wrong in your template. There's no HREF in the html:

<td class="productsCell"><a href=""><img src="images/buttons/magneticvehiclesigns.jpg" alt="Vehicle Magnet - Small" title="Vehicle Magnet - Small" width="50" height="30">Vehicle Magnet - Small</a>
<input type="hidden" name="id[2223:1f509da0b7aedcb3dc23afea060040bb][1]" value="785"><div class="productsCell-attributes"><ul><li>    Qty&nbsp;-&nbsp;1</li>
</ul></div>       
</td>

I knew I'd seen this before.
After digging more, I don't think the final "fix" has been decided yet.

Do you mind adding to the discussion over at https://www.zen-cart.com/showthread....pping_cart-php in regard to the read-only-attributes and price prefix, and perhaps help me recreate the problem?

I have added to the other thread.

Trying to diagnose what file is causing the non a href tag to properly link the cart contents...

</ul></div>       
</td>

I have found that in the my template file: /includes/templates/MYTEMPLATE/templates/tpl_shopping_cart_default.php that when I CLONED the template, it changed line 94 from:

<a href="<?php echo $product['linkProductsName']; ?>"><?php echo $product['productsImage']; ?><?php echo $product['productsName'] . '' . $product['flagStockCheck'] . ''; ?></a>

to this:

<a href="<?php echo $product['../../MYTEMPLATE/templates/linkProductsName']; ?>"><?php echo $product['productsImage']; ?><?php echo $product['productsName'] . '' . $product['flagStockCheck'] . ''; ?></a>

I changed it back to the default for the ZCA Bootstrap 4 default and it fixed the linking problem.

to this:

[CODE]<a href="<?php echo $product['../../MYTEMPLATE/templates/linkProductsName']; ?>">.......

Interesting.

I've never used that mod. Good to know it has "issues".
