Fatal error: Cannot redeclare class order_total

[doremient]

I get:

Fatal error: Cannot redeclare class order_total in /home/recover5/public_html/store1/includes/classes/order_total.php on line 13

 

here is the code for that page. Someone ina previous forum mentioned something about a duplicate require calss field but I couldn't find it.

 

I have read through the forums to find this issue come up numerous times but no clear solution for it.

I am using paypal IPN as my payment method.

 

I would appreciate any help you can provide on this!

[spooks]

u have included the same file twice, or similar, check your code, its not a common issue, its a bug u have created!!

[Gauravs]

When was it working properly?

What has changed?

When do you get the error? - and thus narrow down to the file that may have reference to this file

Open it in notepad / any word editor and verify if order_total.php has been included or required

If yes - go ahead and comment out the line to see if you can continue to work without the error.

 

As spooks has said correctly - it is an error to indicate that you are trying to include something that is already occupying the lone seat it should occupy and thus no more place for second instance to get seated and thus the error ..

Thanks I have looked in a a few files and I don't see it doubled.

It happens when I use the paypal IPN and after completing the transaction on return to checkout process.

However, it works fine when I use paypal payments standard.

 

I am not sure If I should look at all the payment modules or the checkout modules. I guess I will just have to look at all of them.

 

You have said this isn't common however I have seen quite a few posts about this issue, just not really and ideas except for the doubling.

[Gauravs]

One of the tools I often use is called Agent Ransack (google it..)

 

If you have a backup copy of your server files on your desktop, simply search for the string using agent ransack - and it would help to speed up the process and show where all the particular file has been referenced. You may use other tools too - if you have any !!!

 

Cheers

I'm getting a similar problem!

 

Except I'm trying to use an original OSC shipping module - item.php!!!

 

This brings up the following error on the shipping modules screen:

 

"Fatal error: Cannot redeclare class item in \catalog\includes\modules\shipping\item.php on line 13".

Where does the error occur? During checkout?

[doremient]

Where does the error occur? During checkout?

 

I get my error after the payment process and it is the redirect from paypal back to my store.

However this only happens when I use the paypal ipn and not web payments standard

[Gauravs]

Replace

require(DIR_WS_CLASSES . 'order_total.php');

with

 require_once(DIR_WS_CLASSES . 'order_total.php');

 

in checkout_confirmation.php & checkout_process.php

 

Also,

were you able to run search and find out if where all does

 require(DIR_WS_CLASSES . 'order_total.php');

appear in your codebase?

 

* You may also change in one file at a time to narrow down further. Again, if this class is being referenced at any other place, making these changes will NOT change the outcome - so you do need to find out where all is it declared as required.

 

Thx

[Nullachtfuffzehn]

To which page are you redirected from the payment when the error occurs?
