If you have problems updating quantity in checkout/cart

Post by artcore » Fri Jun 19, 2015 2:21 am

On products with any options and or recurring profiles I was unable to use the update quantity feature in checkout/cart/edit
The result was an empty []
After some hunting I found that the product[key] gets too long and is filtered by Suhosin PHP protection.
This will give an empty array thus

Code: Select all

if (!empty($this->request->post['quantity']))

never gets fired to do its job.

The standard Suhosin settings for the length is 64 but one product_id + one recurring_id base_encoded and serialized makes up 82 chars.

Code: Select all

var_dump(strlen('quantity[YToyOntzOjEwOiJwcm9kdWN0X2lkIjtpOjUxO3M6MTI6InJlY3VycmluZ19pZCI7aToxO30=]')); //82

Only took my all afternoon as I first suspected mod_security and then a possible bug with OC

Add the following lines to your php.ini

Code: Select all

suhosin.post.max_array_index_length = 256;
suhosin.post.max_name_length = 256;
suhosin.post.max_array_depth = 256;
suhosin.request.max_array_index_length = 256;
suhosin.request.max_varname_length = 256;
suhosin.request.max_array_depth = 256;

You can try to add it to your php.ini in the catalog part or, depending on your hosting create a .user.ini (there's a dot in front of user!)

I hope this will be of any help. I read some people really moved hosts on this matter but it's an easy fix!

Thanks Ernie,
It's always a good feeling to find a fix but takes some effort to not feel bad about the lost hours

Hi Artcore,

Thanks for your reply. I did try adding it to the php.ini in my shop root but no luck.

I have tried removing product options and yes that does now work. I don't have any products with recurring profiles so that isn't a problem. I do need the product options though.

Have sent a link to this thread to my hosting company to see if they can help. They are usually very good at sorting these things so I am quite optimistic!

Peter

All sorted

My hosting company made some changes to allow config of the Suhosin values through my .htaccess file so now all is working perfectly.

Thanks again for your help

Peter

Just double checked the code for 2.1 and it seems 'they' reverted back to the old system for generating keys.
So just use 2.1 onward! You can easily verify this by installing 2.1 in another folder on your hosting account and add a product with options to the cart > update quantity and see what happens.

Code: Select all

//VERSION 2.0
$product['product_id'] = (int)$product_id;

		if ($option) {
			$product['option'] = $option;
		}

		if ($recurring_id) {
			$product['recurring_id'] = (int)$recurring_id;
		}

		$key = base64_encode(serialize($product));

Code: Select all

//VERSION 2.1
$key = (int)$product_id . ':';

		if ($option) {
			$key .= base64_encode(serialize($option)) . ':';
		}  else {
			$key .= ':';
		}

		if ($profile_id) {
			$key .= (int)$profile_id;
		}
