Product Attributes - Option type big problem!

Hi there

 

I recently downloaded and installed the Product Attributes - Option Type Feature contribution, by Didier Debbaut, published on 17 Nov 2004.

 

I am normally pretty good at installing these contributions, however since i've uploaded it all i get the following problem.

 

When I start up my home page all I see is the following:

 

Parse error: parse error, unexpected T_DOUBLE_ARROW in /home/readingniguk/public_html/catalog/includes/classes/shopping_cart.php on line 348

 

Nothing else at all, it seems to be dying straight away.

 

I have included the code for the shopping_cart.php file for anyone in the know to have a look at and point out where i've gone wrong.

 

Any other pages that i could've "messed" up which this problem might stem from?

I was having a similar problem. My resolution was as follows:

 

Change (see part in red)

 

'attributes' => (isset($this->contents[$products_id]['attributes']) ? $this->contents[$products_id]['attributes'] : ''));

 

TO (see the part in red)

 

'attributes' => (isset($this->contents[$products_id]['attributes']) ? $this->contents[$products_id]['attributes'] : ''),

 

Hope that helps.
