More information would be needed here.

- Which OC version are you using?
- Does this error occur by using the API from the admin orders or from the customer's checkout page?

What I am noticing is this error from your first post:
SyntaxError: JSON.parse: unexpected character at line 1 column 1 of the JSON data

OK

<b>Notice</b>: Undefined index: comment in ...
"Comment in ..." (...) where exactly? A location should be provided from the error window.

The most generated errors being found on Opencart forum originates from contributed programming. The increased post counters are caused by redundancies of the same solutions that were already provided prior.

While the fax is not a mandatory field, it may need to be modified.

In catalog/controller/checkout/guest.php file,

find:

Code: Select all

$this->session->data['guest']['fax'] = $this->request->post['fax'];
replace with:

Code: Select all

$this->session->data['guest']['fax'] = '';

if (!empty($this->request->post['fax'])) {
    $this->session->data['guest']['fax'] = $this->request->post['fax'];
}
In catalog/controller/checkout/shipping_method.php file,

find:

Code: Select all

$this->session->data['comment'] = strip_tags($this->request->post['comment']);
replace with:

Code: Select all

$this->session->data['comment'] = '';

if (!empty($this->request->post['comment'])) {
    $this->session->data['comment'] = strip_tags($this->request->post['comment']);
}

In catalog/controller/checkout/payment_method.php and catalog/controller/checkout/shipping_method.php file,

find:

Code: Select all

$this->session->data['comment'] = strip_tags($this->request->post['comment']);
replace both with:

Code: Select all

$this->session->data['comment'] = '';

if (!empty($this->request->post['comment'])) {
	$this->session->data['comment'] = $this->request->post['comment'];
}

Hi

I have this same issue, and thanks to the above posts, I was able to fix all but one JSON error

I've updated onto a copy of my store and the upgrade script worked like a charm from 2.0.3.1 to 2.2.0.0

I had this same error for guest.php and shipping_method.php but was able to find the fix on the forum.

I haven't been able to find a fix for this one though:
SyntaxError: JSON.parse: unexpected character at line 1 column 1 of the JSON data

OK

<b>Notice</b>: Undefined index: comment in <b>/.../catalog/controller/checkout/payment_method.php</b> on line <b>186</b>[]
Any help greatly appreciated

Nabtrans Payment Gateway is a contributed extension as it is not part of the core. Contact the payment gateway developer of that extension to resolved this issue.

I've just completed testing the rest of the different checkout processes to trigger the JSON errors (I only have default/no wholesale account log in so haven't tested different account type log ins)
The following checkout processes produce these errors - I've tried making changes, to the above suggestions, and editing shipping/payment address , but I receive internal error message, and not sure what causes it.

Any help to let me know what to replace the associated lines with, greatly appreciated

**LOGGED IN ACCOUNT CHANGE OF ADDRESS**

I made these edits: same again for address_2 - THIS FIXED THE ABOVE ERROR
replaced this

Code: Select all

$this->session->data['shipping_address']['company'] = $this->request->post['company'];

}
with

Code: Select all

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

This code change will create an missing } ending.

			}
at the end of your change. ;D
